• Monitoring bespoke software with Zenoss

  - by Andy S

  We've got a lot of back-end applications that we need to monitor the performance of (metrics such as orders waiting to be processed, time since last run, etc). Currently, this is done by an in-house watchdog application that fires out emails whenever a threshold is exceeded, but there's no way to acknowledge an issue and squelch these alerts. Rather than build our own complete alerting system, we'd like to tie in to the Zenoss installation we use to monitor our servers. I've found a few articles on creating events programmatically, but I'd rather Zenoss itself monitors the values that the current watchdog app is looking at (so we get the benefits of graphing and history as well). Is it possible, then, to programmatically provide a data feed (rather than an event) to Zenoss? Or is there another way to go about this?

• Creating an office network and monitoring all activity without a proxy

  - by Robert

  We are setting up our office network and would like to track all the websites visited by our employees. However, we would not like to use any proxy based solutions. Our work is highly dependent on applications in which you cannot configure a proxy. Hence, the approach we would like to follow is setting up a router inside a computer (something like this : http://www.techrepublic.com/article/configure-windows-server-2003-to-act-as-a-router/5844624) This will also allow us to attach multiple ethernet cards and have redundancy in internet connectivity with complete abstraction from the user about which connection is being used. But most importantly, since all the traffic will be going through the computer (configured as a router) I assume there will be a way to run packet analysis on all the request / responses being made. For example, list all the FTP servers connected to (port 21), give a graph of all the URLs visited per day by frequency. Is there already a software which does this ? Or is it possible to build something like this ?

• Network monitoring solution

  - by Hellfrost

  Hello Serverfault ! I have a big distributed system I need to monitor. Background: My system is comprised of two servers, concentrating and controlling the system. Each server is connected to a set of devices (some custom kind of RF controllers, doesnt matter to my question), each device connects to a network switch, and eventually all devices talk to the servers, the protocol between the servers and the devices is UDP, usually the packets are very small, but there are really a LOT of packets. the network is also somewhat complex, and is deployed on a large area physically. i'll have 150-300 of these devices, each generating up to 100+ packets per second, and several network switches, perhaps on 2 different subnets. Question I'm looking for some solution that will allow me to monitor all this mess, how many packets are sent, where, how do they move through the network, bandwidth utilization, throughput, stuff like that. what would you recommend to achieve this? BTW Playing nice with windows is a requirement.

• Looking for comprehensive computer monitoring software

  - by cornjuliox

  Summer in this country is insanely hot. So hot in fact, that I think we just lost a machine due to overheating (last recorded CPU/GPU temp was close to 100 C, now it wont start and lets out a long series of short beeps on power up), but that's not my concern here. Since heat is such a problem for me, I use several different pieces of software to monitor temperatures in my machine. I use MSI Afterburner to monitor GPU temp, control GPU fan speed and for some light overclocking, and then I use Speccy and SpeedFan to monitor the rest of the system, CPU temp and everything. The setup works fine for now, but I want to consolidate all this into one program so I'm not juggling several windows at once. Is there any program out there that will let me monitor the following from a single window: CPU Temp and Fan Speed CPU clock GPU Temp and Fan Speed GPU clock, both core and memory Additionally, mobo temp (Speccy lists both CPU and Motherboard temp, I assume that the latter is referring to North and Southbridge temperatures. I'm also looking for the ability to chart these data points on a graph over time, basically to see just how high the temperatures spike under load and for general analysis. It'd be nice if it could handle overclocking of both CPU and GPU in real time too. Any suggestions? Edit: I forgot to mention that I'm on Windows 7, 64-bit

• Monitoring Dell/HP Servers Running ESXi (Free)

  - by Untalented

  What are you all doing to monitor ESXi servers that run the free edition? With the lack of SNMP support, it seems fairly limited to me. What'd I'd like to be able to do is get some type of alert when a drive or other hardware fails. I've seen a few articles on getting OpenManage installed on an ESXi box (to rebuild an array), but it seems to be quite a pain as well. Even if I get OpenManage working, I won't have alerts without SNMP. Any comments, input, or guidance would be greatly appreciated.

• Convert Spanned Dynamic disk to Basic Help needed.

  - by Mouradb

  Hello all, Here is my scenario; Windows 2008 server on a VM Two VM disks; Disk1 OS Basic Disk2 Data and an Installed Application. Basic Durng the weekend, I was playing with this VM, I wanted to add some space to the Disk2. Created a new disk (disk3), converted it to a Dynamic volum and added this to disk 2 (disk 2 also converted to Dynamic volume) and for some reason these now are spanned volumes. just like an IDOT, I haven't taken any snapshot of this before I've made the changes. My question, is there a way I can re-convert this again to Basic? I don't want to delete and recreate the disk volumes because of the application installed on the disk 2 Any solution or tips I can use?

• GParted detects entire disk as UNALLOCATED SPACE + hd0 out of disk

  - by msPeachy

  Good day to everyone. I hope someone can help me with my problem. I have a dual boot Windows and Ubuntu system. I recently encountered an hd0 out of disk error and wasn't able to boot Ubuntu. So I booted into Windows. After 2 to 3 times of booting and rebooting Windows, I tried booting Ubuntu again but still I get the same hd0 out of disk error. I decided to run Ubuntu from LIVEUSB to try to fix my Ubuntu partition using GParted, but when I run GParted, it shows my entire disk as UNALLOCATED SPACE! The strange thing is that Nautilus still shows and mounts my partitions. Also every time I boot into Windows , my partitions exists and I am able to read and write to them. I have no idea what is wrong. Please help! I can't stand using Windows since most of the tools I use are in Ubuntu. I don't mind reinstalling Ubuntu. In fact I already tried reinstalling using the LIVEUSB but since GParted or the Ubuntu installer itself does not recognize my partitions and shows the entire disk as unallocated space, I decided not to continue. I am currently running Ubuntu from LIVEUSB. Here's the outpuf of sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xb30ab30a Device Boot Start End Blocks Id System /dev/sda1 * 2048 104869887 52433920 83 Linux /dev/sda2 104869888 105074687 102400 7 HPFS/NTFS/exFAT /dev/sda3 105074688 156149759 25537536 7 HPFS/NTFS/exFAT /dev/sda4 156151800 625153409 234500805 f W95 Ext'd (LBA) /dev/sda5 156151808 169156591 6502392 82 Linux swap / Solaris /dev/sda6 169158656 294991871 62916608 7 HPFS/NTFS/exFAT /dev/sda7 294993920 471037944 88022012+ 7 HPFS/NTFS/exFAT /dev/sda8 471041928 625121152 77039612+ 7 HPFS/NTFS/exFAT When I run, sudo parted -l, I got this error message: ubuntu@ubuntu:~$ sudo parted -l Error: Can't have a partition outside the disk! UPDATE I think I might know the problem. The total sectors of sda is 625142448 but the extended partition (sda4) ends at 625153409. Now, my question is, how do I fix this or modify the extended partition (sda4) to matched the total number of sectors? Anyone, please??? UPDATE I was able to fix the unallocated space issue with the help of Rod Smith's tool called fixparts I am now able to view my partitions via GParted in LiveUSB. But the error: hd0 out of disk. Press any key to continue... still persists on reboot. I still can't boot into Ubuntu. Can someone help me please???

• JMX Based Monitoring - Part Four - Business App Server Monitoring

  - by Anthony Shorten

  In the last blog entry I talked about the Oracle Utilities Application Framework V4 feature for monitoring and managing aspects of the Web Application Server using JMX. In this blog entry I am going to discuss a similar new feature that allows JMX to be used for management and monitoring the Oracle Utilities business application server component. This feature is primarily focussed on performance tracking of the product. In first release of Oracle Utilities Customer Care And Billing (V1.x I am talking about), we used to use Oracle Tuxedo as part of the architecture. In Oracle Utilities Application Framework V2.0 and above, we removed Tuxedo from the architecture. One of the features that some customers used within Tuxedo was the performance tracking ability. The idea was that you enabled performance logging on the individual Tuxedo servers and then used a utility named txrpt to produce a performance report. This report would list every service called, the number of times it was called and the average response time. When I worked a performance consultant, I used this report to identify badly performing services and also gauge the overall performance characteristics of a site. When Tuxedo was removed from the architecture this information was also lost. While you can get some information from access.log and some Mbeans supplied by the Web Application Server it was not at the same granularity as txrpt or as useful. I am happy to say we have not only reintroduced this facility in Oracle Utilities Application Framework but it is now accessible via JMX and also we have added more detail into the performance tracking. Most of this new design was working with customers around the world to make sure we introduced a new feature that not only satisfied their performance tracking needs but allowed for finer grained performance analysis. As with the Web Application Server, the Business Application Server JMX monitoring is enabled by specifying a JMX port number in RMI Port number for JMX Business and initial credentials in the JMX Enablement System User ID and JMX Enablement System Password configuration options. These options are available using the configureEnv[.sh] -a utility. These credentials are shared across the Web Application Server and Business Application Server for authorization purposes. Once this is information is supplied a number of configuration files are built (by the initialSetup[.sh] utility) to configure the facility: spl.properties - contains the JMX URL, the security configuration and the mbeans that are enabled. For example, on my demonstration machine: spl.runtime.management.rmi.port=6750 spl.runtime.management.connector.url.default=service:jmx:rmi:///jndi/rmi://localhost:6750/oracle/ouaf/ejbAppConnector jmx.remote.x.password.file=scripts/ouaf.jmx.password.file jmx.remote.x.access.file=scripts/ouaf.jmx.access.file ouaf.jmx.com.splwg.ejb.service.management.PerformanceStatistics=enabled ouaf.jmx.* files - contain the userid and password. The default configuration uses the JMX default configuration. You can use additional security features by altering the spl.properties file manually or using a custom template. For more security options see JMX Security for more details. Once it has been configured and the changes reflected in the product using the initialSetup[.sh] utility the JMX facility can be used. For illustrative purposes I will use jconsole but any JSR160 complaint browser or client can be used (with the appropriate configuration). Once you start jconsole (ensure that splenviron[.sh] is executed prior to execution to set the environment variables or for remote connection, ensure java is in your path and jconsole.jar in your classpath) you specify the URL in the spl.runtime.management.connnector.url.default entry. For example: You are then able to track performance of the product using the PerformanceStatistics Mbean. The attributes of the PerformanceStatistics Mbean are counts of each object type. This is where this facility differs from txrpt. The information that is collected includes the following: The Service Type is captured so you can filter the results in terms of the type of service. For maintenance type services you can even see the transaction type (ADD, CHANGE etc) so you can see the performance of updates against read transactions. The Minimum and Maximum are also collected to give you an idea of the spread of performance. The last call is recorded. The date, time and user of the last call are recorded to give you an idea of the timeliness of the data. The Mbean maintains a set of counters per Service Type to give you a summary of the types of transactions being executed. This gives you an overall picture of the types of transactions and volumes at your site. There are a number of interesting operations that can also be performed: reset - This resets the statistics back to zero. This is an important operation. For example, txrpt is restricted to collecting statistics per hour, which is ok for most people. But what if you wanted to be more granular? This operation allows to set the collection period to anything you wish. The statistics collected will represent values since the last restart or last reset. completeExecutionDump - This is the operation that produces a CSV in memory to allow extraction of the data. All the statistics are extracted (see the Server Administration Guide for a full list). This can be then loaded into a database, a tool or simply into your favourite spreadsheet for analysis. Here is an extract of an execution dump from my demonstration environment to give you an idea of the format: ServiceName, ServiceType, MinTime, MaxTime, Avg Time, # of Calls, Latest Time, Latest Date, Latest User ...

• Alignment requirements: converting basic disk to dynamic disk in order to set up software RAID?

  - by 0xC0000022L

  On Windows 7 x64 Professional I am struggling to convert a basic disk to a dynamic one. Under Disk Management in the MMC the conversion is supposed to be initiated automatically, but it doesn't. My guess: because of using third-party partitioning tools there isn't enough space in front and after the partitions (system-reserved/boot + system volume) to store the required meta-data. When demoting a dynamic disk to a basic disk manually, I noticed that some space seems to be required before and after the partitions. What are the exact alignment requirements that allow the on-board tools in Windows to do the conversion?

• Trying to get Hobbit clients to show cpu, mem, disk, etc

  - by Bryan Agee

  I have a Hobbit server set up with a handful of hosts using conn, http, ssh, and sslcert services, but would like to add the other tests as well. I've installed hobbit-client on a server, and added: # CLIENT:fqdn.example.com to it's host line in bb-hosts, and added: HOST=fqdn.example.com before the default configuration in hobbit-clinets.cfg, but no joy. Does anyone know what else I need to do for those tests to register?

• Get exact size in bytes of a disk & partitions in windows

  - by Antonius Bloch

  Hi, I'm using dd (under cygwin) to copy a shadow image of a disk in windows. Shadow copy will only give me a partion, so what I am doing is: 1) using dd to grab the disk header (32k on Win2003) 2) using dd to copy the shadow partition 3) using dd to copy the end of of the disk (8 meg reserved on Win2003) 4) stitch them all together and boot on KVM I need the exact size of all the partitions and non partitioned space on this windows drive. Unfortunately most windows disk tools seem to fudge the numbers a bit, or at least give me a different size than Linux does. I could guess like this 32k + partition size + 8M, but I want to double check. If I make a mistake I could lose data. This is on a remote & live Windows 2003 server so no offline solutions will be helpful. Latest cygwin is installed.

• Getting an alert when my oracle database goes up or down

  - by CodeSlave

  How can I get an e-mail alert when my oracle database comes up or down? I have a database that I need to know when it goes down (it would be nice to know if it has come back up), preferably from a remote machine. Conceivably I could hack together something that TNSPings my DB and e-mails me when that changes, but I'm hoping there's a free package out there. Something that would run on windows. Any strong recommendations?

• Disable XP disk check using FAT32

  - by mike xie

  Right now I'm using Windows XP and Macintosh on my MacBook Pro via Bootcamp. Sometimes my XP would crash and when I restarted it it would have to go through disk check, although it says I can skip it by pushing a key, but this never worked for me. I did a bit of research online on how to disable disk check and found chkntfs /x c: but when I tried this out in my cmd it said the disk is FAT32 format. I tried to convert my C: drive from FAT32 to NTFS by using convert c: /FS:NTFS but when I tried this it told me to locate my C: drive. I tried to type C: and Bootcamp but couldn't really get past it. I later saw someone said to use this: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager] "AutoChkTimeOut"=dword:0000000 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager] "BootExecute"=hex(7):61,00,75,00,74,00,6f,00,63,00,68,00,65,00,63,00,6b,00,20,\ 00,61,00,75,00,74,00,6f,00,63,00,68,00,6b,00,20,00,2a,00,00,00,00,00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] "SFCScan"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\cleanuppath] @=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,\ 00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,63,00,6c,00,\ 65,00,61,00,6e,00,6d,00,67,00,72,00,2e,00,65,00,78,00,65,00,20,00,2f,00,44,\ 00,20,00,25,00,63,00,00,00 (Save it as .reg and execute it) I have just tried running it but am not really sure if it did anything (my laptop hasn't crashed yet :) ) Firstly, I am wondering if someone can tell me how to check if that script worked? Secondly, if that script didn't work, does anyone have any solution for these problems? Is there another way to disable disk check or is there another way for me to change my FAT32 to NTFS?

• Is there a service for monitoring secured WCF endpoints in the same way that HTTP monitoring service

  - by Ryan ONeill

  Hi all, A service I have in WCF occasionally goes down due a problem with a COM component. While I am troubleshooting I would like to setup another host to make regular calls to this service to monitor availability. It is slightly more complicated that a simple HTTP call though as the service is secured by SSL and WCF authentication (username / password). I'd also like to be able to parse successful calls to see if they return warning / fail states from my code. Would you recommend any monitoring providers for this or is it beyond the simple monitoring they normally provide? Regards Ryan

• How do I refresh Disk Utility?

  - by detly

  I do a lot of live system building, which eventually involves imaging a USB drive with the built binary image: dd if=binary.img of=/dev/sdX sync ...where /dev/sdX is a USB drive. As part of my workflow, I like to have Ubuntu's Disk Utility open so I can verify the drive letter and unmount anything that gets mounted automatically. I also use it to create extra partitions for persistence. The trouble is, after writing the image to the device — and even after the sync operation — Disk Utility doesn't show the new partition. It just shows free space. GParted sees it and fdisk sees it. Even after closing and opening Disk Utility, it still shows only free space. If I click "Safe Removal" and physically unplug and replug the USB drive, Disk Utility will then see the partition. Why do I need to remove and re-insert the drive for Disk Utility to see the partitions on it? Can I force Disk Utility to update its information without needing to do this? (using Disk Utility 3.0.2 under Ubuntu 11.10.)

• SMART says disk failure is imminent due to bad blocks, what do I need to do?

  - by flix

  I have on my hard drive 2 OSes: Ubuntu 12.04 and Windows Vista (I keep it just because of school). Everything was OK on both OSes, but one day on Ubuntu I was getting awkward noises from my notebooks' hard drive and then everything stopped and I couldn't do anything. On Windows everything was OK. Every time I boot Ubuntu I can get 5 minutes normal run time, without problems. After that the hard drive sounds crazy and nothing works. I could run S.M.A.R.T tests from a older Ubuntu CD (10.04) from the GUI (Disk Utility, or something like that and from terminal). From the GUI, I got that the DISK FAILURE IS IMMINENT and I have ~700 bad blocks (or broken blocks, I had that test I while ago) on my HDD. From the terminal (I don't remember if it was fsck or a SMART test command) I got that the HDD will fail in under 24 hours. Since then it passed 2-3 weeks. I've tried "badblocks" but after 10 hours it was still running and I had to stop it. Now I have to use cygwin and other alternatives for my Linux apps on Windows. How can I separate the bad blocks from Ubuntu so it wouldn't use them? Please help.

• DPM 2010 "Disk failed or disk not found"

  - by SysAdmin

  I have an HP Proliant ML110 G5 server with Windows server 2008R2 only dedicated for DPM 2010. This server has a limit in HD of 8TB which has already been met. I'm now stuck in this situation where my disk keeps failing "Disk failed or Disk not found" in the disk management. Only after I reboot the system the disk comes back up. Today I was running my monthly tape backup on a certain protection group and the disk failed again while the tape job was running (so the job wasn't completed). This is the description of the error in the alerts: "The disk Disk 1 - Hitachi HDS722020ALA330 SCSI Disk Device cannot be detected or has stopped responding. All subsequent protection activities that use this disk will fail until the disk is brought back online. (ID 3120)". My backup system is becoming useless! I don't think that is a hardware issue (please correct me if I'm wrong) since the HD works fine for a certain period of time which is becoming shorter and shorter. I basically have no more option to fix this problem. I tried to fix any error that was coming up in the event viewer with no luck (included one regarding the SQL2008 compatibility issue). The disk keeps failing! Now I'm only trying to recover/migrate the data from the disk that is having problem but my issue now is that I cannot add any drives to my server since I already got installed the maximum storage capacity 8TB. I thought about 2 simple options. Please tell me what you guys think about it; Unplug one of the 2 storage pool disks (disk0, that one without problem) from the machine and install a new one in order to migrate the data with the Migration tool for DPM. Remove the defective disk (disk1), put back the disk0 and run the synchronization/consistency check on all the groups to recreate replicas and recovery points. Run diskpart.exe and clean up the disk (loosing all data) and hoping that he will work after I sync all the protection groups. Both solutions are not elegant but I have no better options at the moment. Please I need some help. Thanks for your time Angelo

• Dual boot Windows 7 with Windows 8- Dynamic Disk

  - by MeetM

  Its a long explanation. I have a HP Pavilion dm4 notebook. It has pre installed Windows 7 Home Pre. Recently, I tried to install Windows 8 developer preview on my notebook, but while installing, it only allowed me to insatll it on my primary Windows 7 drive I.e. drive C. I had kept 1 empty partition for Windows 8 but when I selectced that option, the next button at the bottom of the window just grey with some error saying Windows cannot boot from this drive....blah blah blah So I googled and found another way of doing it by VHD(virtual hard disk). This seemed to work but on restarting gave me "VHD_BOOT_INITIALIZATION_FAILED" error. After trying all possible ways for around 10 times, I gave up. I noticed that d only thing difference in d tutorials and my notebook is the Disk type. They all had Basic and I have Dynamic. Is that the reason m not able to boot Windows 8? Any suggestions?

• Monitoring GWT Website

  - by Raf

  We currently monitor our webapps using curl. More and more of our webapps use the GWT framework, which uses tons of javascript, and we can't rely on our curl system to monitor anymore. Therefore, we search the right tool to monitor, but it seems difficult to find a crawler which is light (no Selenium please) but handles javascript correctly. PS : we host our webapps as well as the probes, we don't want any Internet monitoring service.

• Unmounted disk still spins up regularly

  - by Erik Johansson

  I just added a disk, with partitions but none of them are mounted. The disk will still spin up every now and then. it goes like this: ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.37.08 CET ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.46.12 CET Also it always spins up when I shut down the computer. Any tips are welcome, e.g. how can I figure out which process is accessing the disk, are there any daemons doing this? I know it isn't a cron job.

• Can't write to disk

  - by nofacts

  I have seen questions similar to this, but the answers are either beyond me or the situation doesn't quite match mine. Would appreciate some direction. I recently installed Ubuntu 12.04 LTS. The OS is on a disk formatted as ext4. I added another disk to the system and formatted it as W95 FAT 32 (LBA) (0x0c). I did this because I am moving from Windows to Linux, will be needing to go back and forth with data for a while, and might need to move the disk to a Windows machine. There may have been a better format to use, but if so I didn't know any better. I was able to transfer data from an external drive to this FAT32 drive with no problem. Now, though, when I try to create a new folder or write a file to the disk I get a message that the disk is read-only. If I go to the properties, permissions for the disk, for Folder Access it says 'create and delete files'. If I try to change File Access underneath to 'read and write', either nothing happens or I get a message it can't be done. Thank you for any help.

• Windows 7 detects my 1 TB disk as a disk with only 31 MB space

  - by ZelluX

  I've added another 1 TB Western Digital disk on my computer (there is a disk with 250 GB already), and after booting to Windows 7, it recognise the disk, but in the Disk Management panel, it says the disk has only 31 MB TOTAL space, so is what it shows in the EVEREST information. And when I rebooted the computer and entered BIOS, it said the new disk has 0 MB disk capacity. Is there any way to fix this problem?
