Solaris check_mem: top not found!

[anilgupta]

Hi,

I am trying to monitor memory usages of my Solaris Servers "Oracle Solaris 10 8/11 s10s_u10wos_17b SPARC".

It throws message as below.

/usr/local/nagios/libexec/check_nrpe -H 10.92.34.49 -t 30 -c check_mem
top not found!

The script is using 'top' command which is not there in Solaris.

Alternatively, I tried check_memory.sh. It uses 'free' which is also missing on solaris.

What is workaround to get memory status on Solaris server.

Is vmstat available on your system? If so, it looks like you'll be able to use this plugin: https://exchange.nagios.org/directory/P ... ls/details

Thanks for the response cdienger.
The plugin is throwing error as below. The system has vmstat

bash-3.2# ./check_vital
WARNING - need either --vmstat or --netstat or both
bash-3.2# vmstat

bash-3.2#

please suggest

Please disregard the last post.

The command take time to return the output.

bash-3.2# ./check_vital --vmstat
OK - cpu_r=0 cpu_b=0 cpu_w=0 mem_swap=3790128 mem_free=2912160 mem_re=16 mem_mf=89 mem_pi=0 mem_po=0 sr=0 cpu_int=1530 cpu_syc=773 cpu_csw=957 cpu_usr=0 cpu_sys=0 cpu_idl=100

Glad to hear it worked. Are we okay to lock the thread at this point?

[anilgupta]

I need further support on this.

this script/plugin is taking too long to output the result. For example, below command is taking 1 min and 40 seconds. It's too long and it will have performance impact on the server. Is there any workaround for this?

Code: Select all

 date; /usr/local/nagios/libexec/check_nrpe -H 10.92.34.49 -t 600 -c check_vital; date

Secondly, I created service as shown in attached screenshot. But it is timing out after 60.2 seconds, refer attached screenshot. Please note that I updated the nrpe.cfg to increase connection time out and command time out to "600"

[cdienger]

You'll also need to increase the global timeout setting under Configure > Core Config Manager > CCM Admin > Core Configs > General. The setting is service_check_timeout and is set to 60 by default.

Does the data command exist on the Solaris system? If so, what is the output of "date;./check_vital --vmstat;date" ?

I don't know about data command. When I try to run it, I get below:

Code: Select all

bash-3.2# data
bash: data: command not found

date; /usr/local/nagios/libexec/check_nrpe -H 10.92.34.49 -t 600 -c check_vital; date

[cdienger]

"data" should have been "date". Are you able to run "date;./check_vital --vmstat;date" on the Solaris system?
