VMware monitoring improvements VMware performance collector based statistics retrieval was separated from VMware data retrieval: • VMware collector now sends fewer requests to VMware servers, greatly greatly improving performance of configuration data and performance collector based statistics gathering. • VMware performance collector based statistics retrieval is much faster and can be done more frequently memory, otherwise the agent may not start and you will see ”Cannot allocate shared memory for collector.” in the agent log file. This may happen on Solaris 8. If you have installed Zabbix proxy, run
