Thanks Ken.We realized that agent's monitor still needs to be implemented. So, we are implementing a mechanism of sending fail/restore events from external monitoring service to the resource agent.From: Ken Gaillot <kgaillot at redhat.com>Sent: Mon, 13 Apr 2020 19:31:19To: Cluster Labs - All topics related to open-source clustering welcomed <users at clusterlabs.org>Subject: Re: [ClusterLabs] Integrate external alerts with pcs clusterOn Sat, 2020-04-11 at 11:04 +0000, Ajay Srivastava wrote:>> Hi,> In my environment I have a pacemaker cluster running which has> various software services as resource agents.> These services have dependency on some hardware components.

In that case your approach is good.However you still need the probe action to work. The normal agent'smonitor should still be able to successfully detect running or notrunning when run once. Pacemaker will do this on every node beforedeciding whether to start the resource.> 2) I can find --fail option in crm_resource but not in pcs cli.
