 Description   

Agent collector process makes heavy load on Solaris with zone (vm) and many cpu cores.

For example

  • Solaris machine has 32 cores
  • 18 VMs work on that machine
  • Zabbix agent works on each VMs

This case agents makes 10% cpu usage.

Hello, Solaris users!

When started, Zabbix collector determines number of processors and allocates memory accordingly.
Can we assume that number of processors does not change over time ?
Or new processors can be added, old ones can disappear at any time without rebooting Solaris and the Zabbix collector needs to understand it?

Code reviewed and substantially modified to include caching pointers to kstat list elements and to deal with changing number of processors. Testing was done only with fixed number of processors. It would be good if somebody could test it with dynamic adding/removing processors (if that is possible at all).

Proposed modifications in development branch svn://svn.zabbix.com/branches/dev/ZBX-6576, r35710.

Successfully tested. No visible load (0.00%) detected by zabbix agent on a 24 core sparc machine.
