I've configured ESXi monitoring in nagios. i'm using vCenter read-only user session to monitor all esxi. there are around 200 esxi & in total nagios has 850 checks for all esxi. vCenter user session file is used for authentication of each nagios check. Now, the issue is that session file getting ended unexpectedly not sure why this is happening.
I've observed that session file remains active if i use that only for few ESXi And only gets ended if there are lots of esxi checks are using same session file.
how to overcome from this issue ?
is there any configuration changes needed in vCenter server ?
do i need provide any extra parameters while creating session file ?
i'm using below script for creating session file----
#!/usr/bin/perl -w
