SOS: pacemaker.log isn't collected by the plugin on HA deployments.
At the request of the pacemaker and cluster developers we collect crm_report data for these components. This includes several log files (although I don't know if any map directly to pacemaker.log since they are renamed in the crm_report archive). I'd rather not work around this so if you need additional data collected on pacemaker systems please ask for it to be included in crm_report.
