Hi all, hi Henrik,

at my company we have some HA (say, LVS or web proxies manager with heartbeat, active/standby setup) clusters, and wish to monitor resources only on the active node.

In a setup such as :

hosts = vs1 and vs2 procs = squid running on master only a custom test named "clustermaster" that gets green when master, and clear otherwise.

There are several ways to do so :

• add a resource in heartbeat so it starts a "abstracted" hobbit client (with hostname "vsmaster" instead of vs1 or vs2). Configure the hobbit-clients.cfg to monitor heartbeat-managed resources for this virtual host. Simple, straightforward.

• add a server-side extension that checks the "clustermaster" color and reconfigures the hobbit-clients.cfg accordingly.

• add a server-side extension that checks the "clustermaster" color and mimics the behaviour of a local client.

• add a "IF" keyword to hobbit-clients.cfg syntax to condition every check possible. (something like PROC squid 1 1 red IF vs1.clustermaster=green).

As usual, the most elegant solution (the last) in the harder. Henrik, could you imagine putting it in hobbit ? If not, I'll do it at some point.
