  • Monitor total service uptime using Icinga

    - by dhh
    I am using Icinga (Nagios fork) for monitoring ~10 webservers, each one providing different services. I would now like to provide an aggregated view on the server states on our companies intranet, providing information like: server | state | last downtime | Ø uptime (month) | Ø uptime (year) Srv1 | OK | 2013-10-09 | 99,5% | 99,8 % Srv2 | ERROR | 2013-10-31 | 73,1% | 85,4 % Is there a possibility to get those values from icinga?

  • Hot-swap drive got new name, can I change it on-the-fly?

    - by T.J. Crowder
    One of the HDDs in my server's RAID config failed, so I took it out of the array and had the data center hot-swap it. They've done that, but now the new drive is /dev/sdc rather than /dev/sda. I suspect — correct me if I'm wrong — that if I reboot the server, it will be /dev/sda again, so I'm hesitant to add it back to the array as /dev/sdc because I don't want to lay a trap for myself to fall into on the next reboot. I'd just as soon not reboot the server if I don't need to (if I do need to, well, too bad for me). Is there a way I can change the device name from /dev/sdc to /dev/sda without rebooting? This is on Ubuntu 10.04 LTS. It's an md array ("Linux Software RAID"), where currently one of the devices (there are a couple of them) looks like this ("degraded" because I've removed the old /dev/sda from it): # mdadm --detail /dev/md0 /dev/md0: Version : 00.90.03 Creation Time : Sun Oct 11 21:07:54 2009 Raid Level : raid1 Array Size : 97536 (95.27 MiB 99.88 MB) Used Dev Size : 97536 (95.27 MiB 99.88 MB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Thu Jun 30 09:31:16 2011 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 UUID : 496be7a5:ab9177ed:7792c71e:7dc17aa4 Events : 0.112 Number Major Minor RaidDevice State 0 8 17 0 active sync /dev/sdb1 1 0 0 1 removed Thanks, Update: Reading through the kernel md documentation, I suspect that if the name changes on reboot, it won't matter. (Good design, that.) Here's why: Boot time autodetection of RAID arrays When md is compiled into the kernel (not as module), partitions of type 0xfd are scanned and automatically assembled into RAID arrays. This autodetection may be suppressed with the kernel parameter "raid=noautodetect". As of kernel 2.6.9, only drives with a type 0 superblock can be autodetected and run at boot time. The kernel parameter "raid=partitionable" (or "raid=part") means that all auto-detected arrays are assembled as partitionable. I do have md compiled into the kernel, so I'm rebuilding the array now and will do the reboot to see what happens. Even if it works, the above doesn't answer the question I actually asked, so unless someone comes along and answers that question in the meantime (I'd be interested, even if it's not necessary for what I'm doing this very moment), I'll just delete the question to keep noise down.

  • Opsview Notifications, how to report event duration

    - by dotwaffle
    At present, Opsview reports recoveries in the following format: RECOVERY: Internal Alarm is OK on host Ellie: SNMP OK - 0 Service: Internal Alarm Host: Ellie Alias: Ellie Address: 1.2.3.4 State: OK Comment: () Date/Time: Mon Oct 5 14:57:53 BST 2009 Additional Info: SNMP OK - 0 What I would ideally like to do is add a "duration" field, so that you can tell without scrolling back on a Blackberry how long the event has been at fault for. Is there an easy solution to this?

  • Celery - minimize memory consuption

    - by Andrew
    We have ~300 celeryd processes running under Ubuntu 10.4 64-bit , in idle every process takes ~19mb RES, ~174mb VIRT, thus - it's around 6GB of RAM in idle for all processes. In active state - process takes up to 100mb of RES and ~300mb VIRT Every process uses minidom(xml files are < 500kb, simple structure) and urllib. Quetions is - how can we decrease RAM consuption - at least for idle workers, probably some celery or python options may help? How to determine which part takes most of memory?

  • Enforce user time restrictions to log out or off from Windows 7

    - by javamonkey79
    How can I limit the time spent on the computer or force a log out from a Windows 7 machine? I used to use Windows Steady State to limit users (kids) from being on too long but SteadyState does not work with Windows 7 Home Premium and is discontinued. Is there a way to set this up in Windows 7 where it will kick off a user after a set time? Or perhaps there's an alternative program that can help limit the time one user is at the computer.

  • Create kickstart configuration file from existing configuration.

    - by ÜMineiro
    Is there a script or another way to automatically generate a kickstart configuration file from the system state of an existing server so that the file can be use to replicate (not clone) the configuration of the system in another install? I know that the anaconda-ks.cfg file is stored on the /root dir. but the system in question have been extensively changed since it's installation, and the file is of no use now.

  • Strange Ubuntu linux boot behaviour

    - by Slartibartfast
    I've recently installed Ubuntu 9.10 on a desktop machine as the only OS. If put in a hibernate, it wakes up normally, but if turned of completely, after turning on there is no "beep" sound from BIOS and HD lamp blinks for a while then stops. When I hit reset in that state, it bots normally. What is going on and how could I fix it?

  • Nagios Availability Report plotting in Graphite

    - by Roman Zenka
    I would like to plot my Nagios availability reports over time. Does anyone know a plugin that would do so? I found 'graphios' at https://github.com/shawn-sterling/graphios that would plot extra data provided by plugins. What I need instead is a plugin that would plot information such as: 'the service was in ERROR state 0.5% of the time last week, while the week before it was 1%'. This would be useful for knowing whether the overall stability is getting better.

  • Spanning-Tree and redundant links

    - by Franko
    I have 2 switches which have redundancy between them, meaning fa0/1 on SW1 is connected to fa0/1 on SW2, and fa0/2 on SW1 is connected to fa0/2 on SW2. Both of the switches have the same BID, however the MAC address of SW1 is numerically lower, hence making it the root bridge. Now my question is, on SW2, what determines which of fa0/1 and fa0/2 becomes the RP (Root Port) and the other on blocking state?

  • rsync & rdiff backup combination giving erros

    - by Maikel van Leeuwen
    On the server I'm making every day a backup with rdiff-backup like: rdiff-backup /home/ /backup/home Then every week I want to make a rsync backup offside with sshfs like: rsync -avz /home/server/backup/home /backup/server-home/ This is giving me the following errors: Fatal Error: Previous backup to /backup/server-home/. seems to have failed. Rerun rdiff-backup with --check-destination-dir option to revert directory to state before unsuccessful session. Does anybody have a good solution to deal with this errors/situation? *2x edit for typo's

  • Puppet and launchd services?

    - by Joel Westberg
    We have a production environment configured with Puppet, and want to be able to set up a similar environment on our development machines: a mix of Red Hats, Ubuntus and OSX. As might be expected, OSX is the odd man out here, and sadly, I'm having a lot of trouble with getting this to work. My first attempt was using macports, using the following declaration: package { 'rabbitmq-server': ensure => installed, provider => macports, } but this, sadly, generates the following error: Error: /Stage[main]/Rabbitmq/Package[rabbitmq-server]: Could not evaluate: Execution of '/opt/local/bin/port -q installed rabbitmq-server' returned 1: usage: cut -b list [-n] [file ...] cut -c list [file ...] cut -f list [-s] [-d delim] [file ...] while executing "exec dscl -q . -read /Users/$env(SUDO_USER) NFSHomeDirectory | cut -d ' ' -f 2" (procedure "mportinit" line 95) invoked from within "mportinit ui_options global_options global_variations" Next up, I figured I'd give homebrew a try. There is no package provider available by default, but puppet-homebrew seemed promising. Here, I got much farther, and actually managed to get the install to work. package { 'rabbitmq': ensure => installed, provider => brew, } file { "plist": path => "/Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist", source => "/usr/local/opt/rabbitmq/homebrew.mxcl.rabbitmq.plist", ensure => present, owner => root, group => wheel, mode => 0644, } service { "homebrew.mxcl.rabbitmq": enable => true, ensure => running, provider => "launchd", require => [ File["/Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist"] ], } Here, I don't get any error. But RabbitMQ doesn't start either (as it does if I do a manual load with launchctl) [... snip ...] Debug: Executing '/bin/launchctl list' Debug: Executing '/usr/bin/plutil -convert xml1 -o /dev/stdout /Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist' Debug: Executing '/usr/bin/plutil -convert xml1 -o /dev/stdout /var/db/launchd.db/com.apple.launchd/overrides.plist' Debug: /Schedule[weekly]: Skipping device resources because running on a host Debug: /Schedule[puppet]: Skipping device resources because running on a host Debug: Finishing transaction 2248294820 Debug: Storing state Debug: Stored state in 0.01 seconds Finished catalog run in 25.90 seconds What am I doing wrong?

  • Macbook Pro 2010 13,3'' 2,4 vs. 2,66Ghz

    - by Milde
    Hi, is the 13,3'' MBP 2,66ghz worth the extra 300€, comparing it to the 2,4ghz version? What CPUs are installed? P8600/P8800 ? 300€ for 70GB more space and 0,26ghz or would it be better to use the 300€ for a solid state disk? What's your opinion? Thanks in advance, Milde

  • iptables intercept local traffic

    - by Anonymous
    i hope someone can help me out with somewhat simple task. I'm trying to redirect a client in my router through my desktop PC, so i can dump the traffic and analyze it (its potential source of poisoning the network with malicious packets). However i don't have a second NIC on my hands and i was hoping i can redirect all the traffic from that IP through my PC. In essence to become MITM for the client. Does anyone have any idea where to start: Current state: (localip)-(router)-(internet) And what i want to do: (localip)-(pc)-(router)-(internet)

  • How to make a persistent acknowledgment in Icinga/Nagios?

    - by blerontin
    I am using Icinga (Nagios fork) to also monitor uptime of external hosts and services. Currently when looking at the "Critical" count I find it difficult to decide if an internal service is affected (I should take immediate action) or an external service (I just acknowledge the problem). Is there a way to keep a problem acknowledgement for future down-times of the checked host/service? Is there some way to auto-acknowledge the state change of external hosts/services?

  • What is the best way to secure MySQL data on a laptop *without* whole-disk-encryption?

    - by GJ
    I need to have the mysql data on my laptop stored in an encrypted state so that in case of the laptop being lost/stolen it will extremely difficult to recover the data without the password. I don't wish to use whole disk encryption, due to the performance impact it will have on other disk-intensive programs' usage. What could be the ideal solution for me balancing security and performance? Thanks!

  • Is this iptables NAT exploitable from the external side?

    - by Karma Fusebox
    Could you please have a short look on this simple iptables/NAT-Setup, I believe it has a fairly serious security issue (due to being too simple). On this network there is one internet-connected machine (running Debian Squeeze/2.6.32-5 with iptables 1.4.8) acting as NAT/Gateway for the handful of clients in 192.168/24. The machine has two NICs: eth0: internet-faced eth1: LAN-faced, 192.168.0.1, the default GW for 192.168/24 Routing table is two-NICs-default without manual changes: Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 (externalNet) 0.0.0.0 255.255.252.0 U 0 0 0 eth0 0.0.0.0 (externalGW) 0.0.0.0 UG 0 0 0 eth0 The NAT is then enabled only and merely by these actions, there are no more iptables rules: echo 1 > /proc/sys/net/ipv4/ip_forward /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # (all iptables policies are ACCEPT) This does the job, but I miss several things here which I believe could be a security issue: there is no restriction about allowed source interfaces or source networks at all there is no firewalling part such as: (set policies to DROP) /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT And thus, the questions of my sleepless nights are: Is this NAT-service available to anyone in the world who sets this machine as his default gateway? I'd say yes it is, because there is nothing indicating that an incoming external connection (via eth0) should be handled any different than an incoming internal connection (via eth1) as long as the output-interface is eth0 - and routing-wise that holds true for both external und internal clients that want to access the internet. So if I am right, anyone could use this machine as open proxy by having his packets NATted here. So please tell me if that's right or why it is not. As a "hotfix" I have added a "-s 192.168.0.0/24" option to the NAT-starting command. I would like to know if not using this option was indeed a security issue or just irrelevant thanks to some mechanism I am not aware of. As the policies are all ACCEPT, there is currently no restriction on forwarding eth1 to eth0 (internal to external). But what are the effective implications of currently NOT having the restriction that only RELATED and ESTABLISHED states are forwarded from eth0 to eth1 (external to internal)? In other words, should I rather change the policies to DROP and apply the two "firewalling" rules I mentioned above or is the lack of them not affecting security? Thanks for clarification!

  • How to I alias a hostname?

    - by Jonas Byström
    Is it possible to keep a network alias - without specifying the IP address in the hosts file? For instance, I have abcd.efgh.com but want abcd -> abcd.efgh.com so that ping and ssh work as they normally would. I want it to work with dynamic IP on abcd.efgh.com, that's why I don't want to state the IP address explicitly.

  • Ubuntu home directory selectively reverting

    - by Zurahn
    This is perhaps the most bizarre problem I've ever come across, but my home directory in Ubuntu 9.10 seems to be occasionally reverting to a previous state. For example, I'll change a setting in Opera (whose settings folder is in my home directory), then upon subsequent restart, may or may not have reset to what it was previously. This happens with all programs with settings in the home directory. I have the Kubuntu desktop downloaded as well, so I am using KDE4. Any ideas?
