we are having problems with IBM/Lenovo x3650 M5 IPMI monitoring (IMM2). we have 5 physical servers, trying to monitor 20 IPMI items per server in 1800 sec intervals. we receive tons of zabbix alerts per day like this:
Zabbix unreachable poller processes more than 75% busy
Zabbix ipmi poller processes more than 75% busy
zabbix log is full of messages like this:
CentOS 7, Zabbix 2.4.7 from repo, some settings:
any hint what could be wrong here? current situation makes IPMI monitoring pretty much unusable 
does it make any sense to play with the authentication algorithm and privilege level on the IPMI tab of the hosts? or any other suggestion?
