Media types are processed Retry interval: • Functionality of the database watchdog process has been merged into the alert manager and the watchdog process itself removed. 6 Improved notifications 6.1 Notification on problem acknowledgement number of IPMI pollers this could easily overloaded BMC controllers. Since Zabbix 3.4, a new IPMI manager process has been added to schedule IPMI checks by IPMI pollers. Now a host is always polled by the
