I have a agent that change to grey and don't receive data. I want receive alert when it change to grey. How I do this?
Now for those of you who attended Mike Sydor's broadcast on APM Tips and Tricks (or watched the replay [hint hint]), you would have seen his recommendation about using the Metric Count, along with using ConnectionStatus to feed into ABA.
Here's the link to the replay => http://goo.gl/PZwTeu
Thank you very much for your hint.
I don't understand how this solve my problem. Can you help me?
You should not be monitoring when the agent goes completely unavailable; that is too late and does not show performance.
You should instead monitor ConnectionStatus in conjunction with Metric Count to see whether your JVM is actually performing any work.
I would highly recommend you take the time to watch Mike's presentation on BrightTalk on this subject.
