A perl plugin using Sys::Statistics::Linux
Thanks to Jonny Schulz, the author of Sys::Statistics::Linux, for his great work (http://search.cpan.org/~bloonix/) !
v1.2 Changelog :
- Add Paging statistics
- Add swapused and active memory on perfparse statistics
- Remove unused -H option (mthuijs)
v1.3 Changelog :
- Add uptime check, warning threshold in minutes (csterley)
- Replace /usr/local/nagios/libexec with FindBin (eulen)
- Fix reports network traffic in bytes (dbsanders)
v1.4 Changelog :
- Illegal division by zero (helium_rday, RedFish)
- Get the cache out of the used memory (waterdeep, dbsanders)
- Removed unused $return_str on check io disk (RedFish)
- Add steal cpu statistics
v1.5 Changelog :
- Add paging statistics to check for major faults (kevin@candidsource.com)
- bug, when using unit=MB for disk usage, the perf data writtens only KB (john12)
- Bug, multiple pipe on IO perfcournter (ledistordu)
- Add CPU context switch statistics

Hi Team ,
I am new in linux and using nagios , I want to understand what are these parameters works with this scripts .
/usr/local/nagios/libexec/check_linux_stats.pl -M -w 99,50 -c 100,50
What is the meaning of -w 99,50 and -c 100,50 . What are these values .
Please help me to understand it in memory script .

Nice little collection.
Is there a set of pnp4nagios templates for it?

I have made some changes to this plugin at https://github.com/apsivam/monitoring_plugins/blob/master/check_linux_stats.pl.
How can I submit PR?
My changes:
*) percentage based check for disk usage will return percentage perfdata instead of KB
*) added an option to exclude file systems types for disk usage check so that we can exclude file systems like tmpfs, devtmpfs, etc.

Hi,
Great work.
I am fairly new to linux and nagios. But is there a tutorial/Link to import and run a plugin?
Thanks in advance!

Congratulations for the plugin. I like a lot, but it seems to have problems to execute NRPE, as when I run this plugin with NRPE it is unable to read the output. I have seen that other people have the same error. Could you help us to execute this plugin in remote? I have configured it, but it doen't work.

The plugins is great.. working with everything really fine but while i am using the unit variable with MB for Network Usages then its showing the default KB value.

Works great!

I really like this plugin and have written an extension which I'd like to send to you.
However, I can't seem to reach the owner by email at plugmon@free.fr
I get a "550 5.2.1 This mailbox has been blocked due to inactivity" error message.
How can the owner be reached?

Hi!,This plugin is great i can do a lot of things with only one command,thanks to the developer.
In the shell all works fine,but i can't show it in the WEB-GUI(Of course before that I added the plugin to the nrpe.cfg and reload the nagios service.)
Whats is the problem here?
Thanks a lot for your support.

Hello,
great check.
I've found a little bug using hte CPU count.
It show me , on the perfdata, the entire help screen, just after the steal percentage:
[root@ph742502]/usr/local/nagios/libexec# ./check_linux_stats.pl -C -w 70 -c 100 -s 2
CPU OK : idle 91.85 |idle=91.85%;70;100 user=0.59% system=0.34% iowait=7.12% steal=0.00%check_linux_stats v1.5

-h, --help
print this help message
-C, --cpu=CPU USAGE
-P, --procs
-M, --memory=MEMORY USAGE
Could be possible to solve?
i was not able to find it on the check_cpu section, it looks ok to me (but i'm not a programmer).
Thank you.

Hi,
This plugin is indeed superb.
I found a bug that when using unit=MB for disk usage, the perf data writtens only KB.
So to fix, i made changes on line no. 378 from
$perfdata .= " $mountpoint=$usage$o_unit";
To
$perfdata .= " $mountpoint=$tmpusage$o_unit;;;0;$tmptotal";
Addition $tmptotal in perf data will set the max MB in the graph.
Let me know,
regards,
John.

I have a perfcounter problem with 1.4.1 :
/usr/lib/nagios/plugins/check_linux_stats.pl -p sda2,sda5 -I -w 100,70 -c 150,100 [16:04:44]

Need this result :

I recently tried to email the owner of this plugin however I got the following error:

I ran into 2 really minor issues;
- Sys:Statistics relies on YAML:Syck, but the plugin doesn't complain if that fails.
- the plugin itself does not mention that the -I option needs 2 -w and -c variables.
and I have a small request as well; on virtual machines using lvm you often have a lot of 'disks' attached but most of them are loopback and virtual devices, if you add an option no-fake-disks-for-me-no-sirree (or a shortcut for that), you could loop through the devices in /sys/block/ and use readlink to remove the virtual devices from the list. This saves a lot of output when you don't want to use -p.

Hi,
First of all, I want to congratulate you on your excellent work with this plugin!
I have a question, I don't understand at all how are obtained the net statistics...
If I check TxBytes in /proc/net/dev to review statistics for bond0, I watch a large number in bytes: 7342573046357
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
bond0:1259548428146 14687025821 0 0 0 0 0 0 7342573046357 15194696711 0 0 0 0 0 0
But, If I check the Nagios web interface, this amount doesn't match with the previous value:
/proc/net/dev = 7342573046357
Nagios Web = 5323572.80B
How the plugin estimate these values on the Nagios web interface?
Thanks in advance.

Hi,
Thanks for the great plugin. If NFS mounts on the system are unresponsive then an unrelated disk check using this plugin times out.
Can this be fixed?
