How monitor a HA failover situation?

[Luc Christiaens]

If you run with a HA protected main hub + 2 proxy servers with tunnels to all the hubs each protected by a HA probe

When HA is implemented (like in document: https://community.broadcom.com/enterprisesoftware/communities/community-home/digestviewer/viewthread?GroupId=1315&MessageKey=f28d1578-1ac9-45db-903d-b46ccbd5041c) you can find yourself running in failover mode without really remarking that you are in failover mode.

Question: What would be the best/ideal callbacks, db fields,.... to create a report/qos/dashboard that give a good overview of your HA status?

I would like to create an automated script that gives you such overview, but only the callback on HA probe: get_status is not really clear in what HA is doing.

Any suggestions, ideas?

Hi Luc,

As you are much more qualified than most of us, I don't think I can give you a useful idea, but I can use the opportunity to learn something.

I'm not sure what you actually need, but I have a few ideas that I would use:

• Process the HA alarms; the last one should give an indication on what HA is doing, assuming that HA probe is running, which you can find out with get_status callback;
• Monitor ha.log with logmon, similar to the option above;
• Find out which data_engine probe is running
• Check if primary hub is available
