(Sorry for the duplicate email, I forgot to CC the list) Assuming you're using the default setup (RadosGW, FastCGI, and Apache), it's the same as monitoring a web site. On every node, verify that request for / returns a 200. If the RadosGW agent is down, or FastCGI is mis-configured, the request will return a 500 error. If Apache is down, you won't be able to connect.
I'm also monitoring my load balancer (HAProxy). I added alerts if HAProxy marks a node offline. That's the basics, but you can get more complicated if you want. You could add a heartbeat file, and verify it's being updated. You can monitor the performance stats returned by /usr/bin/ceph --admin-daemon /var/run/ceph/radosgw.asok --format=json perf dump. I'm not doing a heartbeat, but I am monitoring performance. If the latency per operation get too high, I alert on that to. It's really noise during recovery, but useful when the cluster is healthy.
