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

I have this error NRPE: Command 'check_cpu_usage' not defined. It is the same for all other commands.
This command works on my remote server which i want to monitor . /usr/local/nagios/libexec/check_nrpe -H localhost -c check_load
However running /usr/local/nagios/libexec/check_nrpe -H localhost -c /usr/local/nagios/libexec/check_linux_stats.pl -M
does not work. it says that the plugin requires that i have NRPE daemon running on the remote host. My remote host does have NRPE daemon running. Furthermore, adding the command into nrpe.cfg and adding it into the service gives me NRPE: Command "check_memory_usage"not defined.
sorry for bad english

Second, memory usage is reporting used as used+cached, so it could be misleading, I'll modify for my environment IDK if you would like to patch your code.
THANK YOU for sharing your amazing piece of work!

Hi,
Please let me know what is means..

Hi,
This format is the same as the default format that is used by the command 'uptime', 'w', or 'cat /proc/loadavg'
./check_linux_stats.pl -L -w wload1,wload5,wload15 -c cload,cload5,cload15
Very nice plugin!
But how to use for remote hosts and syntax in
commands.cfg...
Thanks a lot!

Hi,
Did you try nrpe (or nsca) :
# command.cfg on nagios server
# $ARG1$ = check_cpu_usage,check_mem_usage,etc..
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
# nrpe.cfg on the remote server

Hi,
The Usage message for the script suggests there is a "-H " option, but it doesnt appear to be actually implemented. Any chance you have a version in the pipeline that will have that working? At the moment I would need too use NRPE to utilise this plugin. No biggie I suppose, but a "-H" option would mean I dont need to configure NRPE on all linux hosts.

Well, i have the same query as the guy above..how do i generate the graph? it works fine so far with command configs but the graph part i have no idea how to go by it! please assist!
Owner's reply
Hi, you mean the plugin returns perfdata but you cannot getting graph in nagios ?
Hi, this is a really nice plugin based on my module Sys::Statistics::Linux. You should also view the original bloonix plugins on http://download.bloonix.net/sources. Note that the statistic output is in YAML format.
install the package libsys-statistics-linux-perl, it comes with /usr/share/perl5/Sys/Statistics/Linux.pm
but how can i use the graph?
but how can i use the graph?
When i do a local check with the example
./check_linux_stats.pl -C -w 90 -c 100 -s 5
I get a error (see underneath).
It seems he misses a perl module. Is this right?
I could find a perl-Sys-Statistics-Linux rpm (I'm on SLES 10 SP2). Do I have to install this?

Right, you must install Sys-Statistics-Linux perl package.
