Nagios Support Forum

Hi Box293,

it makes times i would like to thank you for the great job regarding the plugin box_293_check_vmware. It works well and the manual is really simple and pretty straight forward.
As i m growing in hosts/services monitoring in nagios i m encountering an issue in my vcenter, it s becoming unstable with the service "CIM HEALTH SERVICE" running over 100%. i decreased the concurrents execution to 10 but the problem still remains the same. VMWARE tells me that this is because of the plugin that generates huge log entries in auth log (in my opinion this not true BUT ...) . They told me to implement "session lock file"... that keeps a session opened that nagios can use for the plugin execution.

my question, is it something true? is it something easy to use with your plugin?

best regards

How much memory and CPU's do you have configures on the vma server?
You can try and increase them and see if that helps out.

thx for your answer.
i have set 12Gb Ram and 4 vCPU up for the vma, with 10 concurrents connections the vma rarely up over 20% CPU usage.
my vcenter has 16Gb RAM and 4 vcpu, i don t understand why my vcenter is so impacted

It doesn't seem like it should be a performance issue. Could you post your nagios.cfg?

Also, can you post the output of tail -100 /usr/local/nagios/var/nagios.log

What version of Core are you running? Did you compile from source or install from distro repos? On what OS is Core running?
