Is there any way for a Pacemaker/Corosync/PCS setup to send a notification when it detects that a node in a cluster is down? I read that Pacemaker and Corosync logs events to syslog, but where is the syslog file in CentOS? Do they log events such as a failover occurrence?
Pacemaker/corosync do extensive logging, even more so if debug is set to on in corosync.conf. Syslog is configurable to log the messages however you want; the default file locations vary from OS to OS.
Monitoring and notification are usually handled by a dedicated package for that purpose, such as nagios, icinga, monit or zabbix. These packages can monitor services on the nodes directly, as well as the health of pacemaker itself. Here, we use icinga with Phil Garner's check_crm plugin:
