Re: Does anyone use 10gR2 Grid control for enterprise wide monitoring ?

What a coincidence; my installation of GC 10gR2 became non-functional yesterday.

I'm just evaluating it; it does not monitor Production systems.

The install is very new, less than a month.

It's stopped functioning correctly on Dec 12.

It stopped monitoring for Policy Violations and Metric Threshold Violations.

The rest of it seemed to work okay; I could browse various targets I know about.

The fact that it did not notify me that it stopped monitoring seems to be a major flaw or bug.

I posted a simple question to the OTN EM-GC forum:

"Is there a checklist, flow-chart, or set of questions I can use to help guide my efforts to troubleshoot this? "

I got no answers.

I'm curious why Oracle does not provide some kind of utility which can tell me the general state of EM-GC and its various components.

Based on my reading of that forum, capturing this state is up to the DBA who knows about the location of perhaps 10 or more log files.

I poked around in the log files and used a status gathering utility for the agent. It appears that I have a communication problem between the agent and other components.

I do remember that when I installed EM-GC, runInstaller asked me if I wanted to secure communications. I said 'yes'.

So now I'm operating under the assumption that this decision has come back to haunt me.

Yesterday, I walked through some steps I found in the EM Advanced Configuration Guide [ ch 4 Enterprise Manager Security ].

I used the steps to verify that the agent and the oms are communicating securely.

Now, my EM-GC is more broken. It has completely lost contact with all of its targets.

So, my impression of EM-GC is poor. I give the product a D. It does have some nice features for browsing the DB. Otherwise, I'd give it an F.

I do, however, want to become proficient with this product.

Maybe the folks here are sharper than the people in the OTN EM-GC forum.

Here is what I see when I use emctl to tell me the state of my 1 and only agent which resides on the same host as both the EM Database and the oms:

bash-3.1$  emctl status agent

Agent is Running and Ready

Does anyone here have any general tips or set of questions which might give some clues on how to troubleshoot this broken implementation?

Notice the status statement:

Collection Status : Disabled by Upload Manager

This looks like a good place to start.

Two obvious questions:
What exactly is 'Collection' and what is 'Upload Manager' ?
