agent groups for many clustered java application servers
I have a websphere cell with ~20 clusters and 3 nodes, so ~20 servers on each node.
Now, I have the same amount of different agent groups, each for every cluster. The agent groups config are basicly the same, or with very few different. But sometimes I have to put some custom sensors on a cluster, what is not necessary for the other ones. It's a little bit difficult to manage so many agent groups. I am thinking about to have only one agent group for every was clusters.
Do you think is a good idea to change?
What is your configuration recommendation for this kind of architecture?
Thanks
The idea with agent groups is that you basically describe a logical tier with one agent group. If you then have 10,20 or even more servers that are part of the same tier in a clustered environment you would still use the same agent group as they logically are the same tier.
It is not wise to create so many agent groups - just for the reasons you mentioned -> too hard to maintain.
So - best practice is to define an agent group by logical tier. Every agent group will also show up as a Tier-node in the Transacton Flow with the option to collapse and expand this tier to actually see each individual server that is part of that tier.
