I am using Zabbix and one of the server that is being monitored is not reporting stats. What I check the zabbix agent log after restarting the service I get the following :
120556:20171212:100507.100 Starting Zabbix Agent [MTN-SA]. Zabbix 2.4.4 (revision 52334).

116620:20171212:100525.039 active check "perf_counter[\LogicalDisk(O:)\Disk Writes/sec]" is not supported

Please help as the server is not reporting stats , but on the web front end the zabbix agent is green as well
