For virtual machine monitoring to work, Zabbix should be compiled with the –with-libxml2 and –with-libcurl compilation options.
After linking it with Vcenter, here are some recommended changes to the service.
StartIPMIPollers=5 ( for ICMP – also requires installation of fping)
StartPingers=25 (ICMP etc)
StartVmwareCollectors=10 (Essential for monitoring vm’s)
VMwareCacheSize=1024M (depends on number of vm’s)
