  • Is there a small business router that shows bandwidth usage graphs in the admin panel?

    - by Robert Drake
    I support a large number of public libraries that are having their networks upgraded in response to a grant application. These libraries are generally home to between 6-15 computers and have little or no tech services either onsite or contracted remotely. In order to justify current and future purchases, a number of the libraries have requested routers that can provide bandwidth usage graphs that they can show to their managing boards. Is there a small business router that displays traffic graphs in the router administration web interface? The router needs to suppport DHCP and basic firewalling. No other features are required. Further, the reports just need to show overall trends. It is not necessary to show traffic by IP, by protocol/application, or by time of day. They just need an overall week to week, month to month, trend line. I'm familiar with MRTG/PRTG/tools that collect SNMP data from the router, but the libraries don't have the expertise for the configuration. I've considered installing the tomato firmware on some cheap home/home office routers, but if there's a commercial product that can be purchased that would be significantly simpler. Also the library boards would be much more likely to approve the purchase of a commercial product over a 'hacked' one. Any assistance would be appreciated.

  • Stripping a spike from rrdtool when removespike.pl doesn't find any

    - by raccettura
    I know when rrdtool graphs (using rrdtool 1.4) network traffic and the host is restarted a spike is a pretty normal thing to see. In the past I've just run that removespike.pl script that is hosted by the author and it strips the spike and I'm good to go. The last few times I've rebooted removespike.pl finds no spikes, but it's obvious that there are spikes. So my question is, how can I easily remove these spikes and get my graphs usable again? Right now it's so skewed it's meaningless.

  • IPMI sdr entity 8 (memory module) only showing 3 records?

    - by thinice
    I've got two Dell PE R710's - A has a single socket and 3 DIMMs in one bank B has both sockets and 6 (2 banks @ 3 DIMMs) filled The output from "ipmitool sdr entity 8" confuses me - according to the OpenIPMI documentation these are supposed to represent DIMM slots. Output from A (1 CPU, 3 DIMMS, 1 bank.): ~#: ipmitool sdr entity 8 Temp | 0Ah | ok | 8.1 | 27 degrees C Temp | 0Bh | ns | 8.1 | Disabled Temp | 0Ch | ucr | 8.1 | 52 degrees C Output from B (2 CPUs, 3 DIMMS in both banks, 6 total): ~#: ipmitool sdr entity 8 Temp | 0Ah | ok | 8.1 | 26 degrees C Temp | 0Bh | ok | 8.1 | 25 degrees C Temp | 0Ch | ucr | 8.1 | 51 degrees C Now, I'm starting to think this output isn't DIMMS themselves, but maybe a sensor for each bank and something else? (Otherwise, shouldn't I see 6 readings for the one with both banks active?) The CPU's aren't near 50 deg C, so I doubt the significantly higher reading is due to proximity - Is anyone able to explain what I'm seeing? Does the output from my ipmitool sdr entity 8 -v here on pastebin seem to hint at different sensors? The sensor naming conventions are poor - seems like a dell thing. Here is output from racadm racdump

  • Alerting system for Munin

    - by akirk
    I am very satisfied with munin as a monitoring tool (as I only have a simple 2-server setup) but its alerting system is very annoying as you can only configure it to send an e-mail upon every check which generates a warning or an error. It seems like the only option is to use Nagios but in Debian it has Apache as a dependency and I already use nginx on my monitoring machine. All I want is to have the possibility to silence/acknowledge the alarm while I am working on a fix, so that I don't get bombarded with e-mails. Nagios seems like an oversized solution for that anyway. Is there any simple solution for that or am I the only one who feels like he needs such a tool?

  • Request bursting from web application Load Tests

    - by MaseBase
    I'm migrating our web and database hosting to a new environment on all new machines. I've recently performed a Load Test using WAPT to generate load from multiple distributed clients. The server has plenty of room to handle the traffic load, but I'm seeing an odd pattern of incoming traffic during the load tests. Here is the gist of our setup: Firewall server running MS Forefront TMG 2010 on Win 2k8 server Request routing done by IIS Application Request Routing on firewall machine Web server is a Hyper-V VM on the Database server (which is the host OS) These machines are hefty with dual-CPU's with six cores (12 total procs) Web server running IIS 7.5 Web applications built in ASP.NET 2.0, with 1 ISAPI filter (Url Rewrite) in front What I'm seeing during the load tests is that the requests all come through in bursts. Even though I have 7 different distributed clients sending traffic loads, the requests come through about 300-500 requests at a time. The performance monitor shows nearly all of the counters moving through this pattern, where a burst of requests comes in the req/sec jumps to 70, the queued requests jumps to 500, the current requests jumps up, the CPU jumps up, everything. Then once it's handled that group of requests, it has a lull for nearly 10 seconds where nearly nothing is happening. 0-5 req/sec, 0 queued requests, minimal CPU usage. Then after 10 seconds of inactivity, another burst comes through, spiking all of the counters once again. What I can't figure out is why the requests are coming through in bursts when I know that the load being generated is not sent that way, especially considering the various load-generating clients sending traffic all in different intervals with random think time's between each request. Is there something in the layers between Hyper-V or perhaps in the hardware which might cause this coalesce of requests together? Here is what i'm looking at, the highlighted metric is Requests/sec, but the others critical counter go with it: Requests Queued (which I'd obviously like to keep as close to 0 as possible). Any ideas on this?

  • W2K INACCESSIBLE_BOOT_DEVICE, with System Commander

    - by Gary Kephart
    I have a system that was originally had Win NT. I added System Commander (SC7) and then added W2K. The relevant partitions are: 0 - Primary - MultiFAT (Has Win NT, mapped to C:) 1 - Extended - with many logical partitions: 1.1 NTFS which has W2K and is mapped to D: 1.2 other logical partitions which are irrelevant to this D: was getting full. It needed room for virus definitions and Windows upgrades. In the past, I had simple used SC7 to resize D: without problems. So I did it again this time. However, upon finishing, I got the message "Unable to create partition". It also marked the partition as unformatted. I checked that the files on the disk were still there using SC7's Partition Explorer, and they were there. I continued and the system managed to boot up fine anyways. Then I rebooted the system again. This time, I got a message saying "INACCESSIBLE_BOOT_DEVICE". I went back in to SC7 and to Partition Commander, and it was still saying that the partition was unformatted but the Partition Explorer still showed the files on the system. I finally decided to resize the partition again, figuring that this would force a rewrite of the partition information. That seemed to work, until I had to reboot again. Now I can't see the files using Partition Explorer, and the Resize button is now disabled. What now?

  • Web traffic/activity monitor

    - by DealingWithAConcernedMom
    Is there a good free monitor that will allow me to monitor my son's internet activity. I'm specifically looking for history of websites visited and time spent on the site. I think that he is visiting sites that his mom would not approve of but is erasing the history etc.

  • System chooses boot drive seemingly at random

    - by Zurahn
    I have a system with two identical 1TB harddrives, where I image to a backup drive using the dd command. When I boot up, though, despite setting harddrive priority in the BIOS, the system sometimes boots the main drive, sometimes boots the backup. My system dual-boots Xubuntu and Windows XP, if that means anything to you. Any ideas?

  • Tool to monitor file size, file existence, parse xml, etc

    - by Artur Carvalho
    I'm trying to find some tool that helps me monitor several things. What are some requirements: Shows results on a web page. Checks existence of files/folders Checks sizes of files/folders Can parse xml files Can have several status depending if it's for instance, after 9pm Ping workstations/Servers to ensure they are on or off create daily/weekly/monthly reports (pdf, html, csv) show daily/weekly/monthly scheduled tasks check if specific users are logged in a machine check which users are logged in in a machine I've looked into some solutions but could not find what I wanted. Usually tools like nagios are more focused in servers, and spiceworks is not so specific. At this point I'm using a little powershell script that does several of these items, but before losing more time probably reinventing the wheel, what tools are out there? Thank you in advance.

  • Ubuntu: Take actions when system temperature gets too high

    - by Josh
    One of the CPU fans on my Compaq Presario laptop running Ubuntu 9.10 seems to have bit the dust. The fan is deep within the case and I intend to replace the laptop in the next 6 months so it's not worth replacing it. I have the laptop on a cooling pad and most of the time the system is fine, CPU temps around 90°-110°F. Occasionally, however, I'm seeing random lockups which I believe is due to the system overheating. How can I configure the system to: Lower the CPU speed when the temperature reaches a certain level? (I.E. 110°F) Shutdown the system when the tempature reaches a critical level? (And what would that be? 130°?)

  • How can I monitor network traffic in an all Mac home network?

    - by raiglstorfer
    I have an all Mac network consisting of an Airport Extreme, 1 MacPro, 1 Mac Mini, 2 MackBook Pros, 2 iPads, and 2 iPhones. The Mac Pro is connected directly to the Airport Extreme via Cat5 and the rest is all running via Wireless. Lately I've been getting prompted by Google to enter Capchas frequently. The message states that I might have software running on my network I'm not aware of. My wireless router is password protected using WPA2 Personal and I frequently change my password so I don't think someone is using the network from outside (but I've no way to confirm this). I'm looking for a relatively cheap (preferably open source) solution that would enable me to monitor and profile the network usage by machine and port. Can someone recommend a solution?

  • Monitor ASP.NET Session State Variables

    - by Dave Johnson
    We are running a number of ASP.NET applications on W2K3 Server and IIS 6.0, and are looking for a way to be able to monitor ASP.NET session state variables (InProc) that are stored in memory. We are thinking there may be some memory optimization opportunities with some of these session state variables potentially consuming large amounts of RAM. Is there a way to accomplish this through IIS or Windows rather than instrumenting all of the individual Web apps with code to monitor the session state variables?

  • Monitor ssh on non-default port with Nagios

    - by obvio171
    I just deployed Nagios on a Gentoo server and everything is fine except ssh, which it marks as "CRITICAL" because it's refusing connections. But that's because it's running on a port different from the default 22. How do I change it so that it monitors the right port?

  • performance monitor in iis 7 to monitor which website is using most resources (asp.net)

    - by Karl Cassar
    I am using Windows Server 2008 R2 and IIS 7.5, and am hosting multiple websites on the same webserver. Is it possible to use Performance Monitor to know on average which website is using the most resources? I've added a user-defined Data Collector Set in Performance Monitor collecting data for 1 day. However, I could not find any details which hint which website is using the most resources. Which counters are crucial to monitor websites? The generated report tells me that the top process is w3wp##1 - how can I know which website it corresponds to? I've also tried to add counters for ASP.Net Applications for all object instances, however % Managed Processor Time (estimated) is 0 at all times.

  • Cacti is ignoring hash marks in interface aliases

    - by Matt Simmons
    I'm attempting to set up Cacti to monitor a router's interfaces, and I'm having trouble getting the graph templates to show the information that I'd like. Our interface configuration looks like this: interface GigabitEthernet3/6 description WalljackNumber # Server info no ip address no shutdown switchport switchport access vlan 116 switchport mode access ip dhcp snooping trust spanning-tree portfast The "Server Info" string is really just the machine name, and a short relevant description, such as "PolarSprings vmnic2". The important part appears to be that it follows the hashmark. When I run snmpwalk, I get the proper output: IF-MIB::ifAlias.230 = STRING: WalljackNumber # Server info But in Cacti, when I go into the graph templates and set the title to this: |host_description| - Traffic - |query_ifName| (|query_ifAlias|) All that shows up in the graph is: switchname - Traffic - Gi3/6 (WalljackNumber #) Which strikes me as a little weird. What I suppose MAY be happening is that somewhere in the cacti stream, it's interpreting # as being a comment and stripping everything after, but I'm not sure. I was hoping someone could tell me that this was a known documented behavior, or that I could change it in a setting that I wasn't aware of. The alternative answer is to change the delimiter from # to something else, but I've got over a thousand lit switchports on an old college infrastructure, and I'm not sure what else might be relying on them.

  • Simple tool to graph memory usage?

    - by dbr
    Is there a script that will show memory usage as a graph, for example as a pie-chart, with each process being being a separate slice? I'm not looking for something like Munin to graph memory usage over time, but rather show the memory usage per-process at a single point in time. To make my request even more obscure, it is for a headless server (so no X applications). The simplest way would be to write a PNG file, or possibly an HTML file (which could use Javascript to allow the filtering of processes, changing between graph-types and so on)

  • ICMP Data Field Modified - What does it Mean?

    - by Lucretius
    Normal ICMP Data fields are composed of a pretty standard 32 byte string of alphabet characters. abcdefghijklmnopqrstuvwabcdefghi I have captured a series of ICMP echo requests using WireShark with a modified Data field and I have no idea what it means. (Underscores represent spaces.) abcdefghijklmnopprstuvwxyzabcdefghi abcdefghijklmnoparstuvwxyzabcdefghi __abcdefghijklmnopsrstuvwxyzabcdefghi __abcdefghijklmnopsrstuvwxyzabcdefghi __abcdefghijklmnopwrstuvwxyzabcdefghi __abcdefghijklmnopdrstuvwxyzabcdefghi__ Note: The position of the "q" character The addition of "xyz" The addition of spaces before and after the payload When you look at the position of "q" horizontally it spells "passwd" which is a Linux/Unix command for changing a users password. Any ideas?

  • Script to monitor free space in Hdd

    - by s.mihai
    I have a server app that crushes when the HDD free space it's a multiple of 4Gb (on a Windows Server 2003). In general i keep track myself o that weekly since i use the machine from time to time. Can you point out an app or script (i don't wanna install powershell, is this doable???) that copies some larger files from one folder to another to get the free space out of the multiple of 4Gb range. Best regards, Mike

  • How to monitor the total number of SQL Server logins

    - by Shiraz Bhaiji
    We have an SQL Server 2005 that is the backend of a web application. The application is partly SharePoint and partly web services accessing the database via Entity Framework. In the performance monitor I am seeing average SQL Logins is ca, 60 per second (max 170), but the average logouts is less than 1. Where can I see the total number of SQL Server logins? Anyone have an idea what could be causing this?
