Hello,

 

The UCMDB Server checks the Probe status periodically, with a period of 3 minutes.

There is possible to see an obsolete status of the probe at a point in time.

Hello,

 

In general, the probe status becomes disconnected when the probe does not ask the server for tasks for at least 5 minutes (note that it does not mean that the probe doesn’t communicate with the server at all. Even if the probe sends results to the server during this time, but does not ask for tasks, the status will be disconnected after 5 minutes). So usually if the the probe status is disconnected for a long time and  the probe service is up,  this would indicate that there is some problem that prevents the probe from getting new tasks from the UCMDB Server.

 

For example, it could be that there is something that the probe is downloading  for a long time (more than 5 minutes).  As long as the probe hasn’t finished downloading a certain resource, it won’t ask the server for the next task.

 

For troubleshooting, you can try check on the UCMDB server side mam.autodiscovery.log. When the probe asks the server for tasks you can see the following (INFO) message in mam.autodiscovery.log: “Total time to retrieve probe <probe_name> tasks is:…”). If you indeed find a long enough timeframe with no such messages for a certain probe, go the wrapperProbeGw log and try to check what was the probe doing during this time.

 

Regards,

Irina

Some of our probes are behind a firewall with not full duplex, but probe initated communication

Will this also cause a disconnect?

 

We were told by HP that did not need full duplex

 

Thanks

TR;

 

The earlier response is good to check.  There are a couple of reasons a probe will show as disconnected (like downloading files from UCMDB, etc).  The mam.autodiscovery.log is the right place to look to see if the probe is connecting to the server.  I'd check the probe logs as well probe-error.log, probe-infra.log and WrapperGW.log to see if there are issues with the probe connecting to UCMDB (which is where you would see the messages if the duplex settings were causing issues).
