</span>Pacemaker has the built-in capability to monitor resources, but it<br>
doesn't do that unless you tell it to. Without a monitor, Pacemaker will<br>
never know when a resource has failed.<br>
<br>
How you configure a monitor depends on whether you use crm shell, pcs,<br>
or whatever, but basically you just specify that you want to create an<br>
operation for the resource of type "monitor" with some interval (such as<br>
30 seconds).<br>
