For SLES15 SP2 I found: monitor_scripts (string): space-separated list of monitor scripts To additionally monitor services within the virtual domain, add this parameter with a list of scripts to monitor. Note: when monitor scripts are used, the start and migrate_from operations will complete only when all monitor scripts have completed successfully. Be sure to set the timeout of these operations to accommodate this delay. > >> (This feature was added before OS containers became popular, so the >> naming is a bit unfortunate.) >> > > _______________________________________________ > Manage your subscription: > https://lists.clusterlabs.org/mailman/listinfo/users > > ClusterLabs home: https://www.clusterlabs.org/ _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
