Customer got few AGs up and running and every thing was good till they start to drop dead, because of JAVA error but that is not the issue now, the question is how to get alert for dynatrace admin if and when AG is disappearing from the grid.
Thanks in advance for your inputs
Solved! Go to Solution.
There's a couple of solutions that come to mind.
One way is to install the OneAgent along with the ActiveGate and monitor the ActiveGate process with it. The upside is you have a lof of visibility into the ActiveGate thanks to the OneAgent but the downside is that it will consume licenses. Some people are afraid this is not possible, but it's absolutely compatible to have both on the same machine.
Another solution is to use the built-in metrics for self monitoring, like dsfm:active_gate.communication.agent_modules.connected. You can create metric events for this metric for the host.name or dt.active-gate.id dimensions, and alert when data is missing or the value is 0, which could indicate a problem. The upside is it costs no licenses and it's a built-in solution, the downside is you have to create the metric events yourself and make sure they are configured correctly with the host names or active gate IDs you're interested in. You can obviously also use any of the other dsfm:active_gate metrics to monitor your ActiveGates in many different ways (CPU, Memory, network, agent load, etc.).
Hope this helps.
But adding OA will cost HU, adding custom metric ,which I was also thinking about, will consume DDU 🤑
Actually we are looking for something more strait forward like the OA alerts on system notifications 🤔
The second solution does not consume any licenses, metric events do not consume DDUs, and the metrics I mention above are not custom metrics, they are built-in, so they also do not consume DDUs.
