I have a 3 node replicaset monitored by MMS. The two secondary nodes show up and report data in MMS, the primary does not.

When I add it manually, it shows in the MMS dashboard as "No Data" for about 20 minutes, then disappears. The only data in the log is shown below.

I've tried to increase the logging level of the agent by changing the logLevel to logging.DEBUG in logConfig.py, but was unsuccessful.

2013-08-29 10:46:20,508 INFO starting non-blocking stats monitoring: 10.X.X.X:27018
2013-08-29 10:46:20,508 INFO starting blocking stats monitoring: 10.X.X.X:27018

2013-08-29 11:06:39,896 INFO stopping non-blocking stats monitoring: 10.X.X.X:27018

Anyone have any ideas how to troubleshoot why the node disappears or increase the logging level to get additional info from the agent?

I opened a ticket with Mongo Inc. and was able to get all of my servers reporting into MMS. Not sure which events were the triggers for success, but I'll post all of the details here: After James added one of the servers back in (see previous comments) it was listed in MMS, but not reporting data. I restarted the MMS agent and the server began reporting into MMS.

I also had two other servers - each a member of a different replica set that didn't show up in MMS. Mongo Inc suggested I add the servers manually to MMS using the "+ Add Host" option. Sure enough- they were identified and after about 10 minutes began reporting data.

In summary- it looks like a combination of adding hosts manually and restarting my local MMS agent were necessary keys in resolving this issue.
