Hi there,
Is it possible to configure an alert upon a threshold not been exceeded but when it’s falls below a certain threshold.
Yes it is.
Example: If real memory usage fall’s below 20%, an alert is then sent
In analysis.cfg, you can specify memory parameters MEMSWAP, MEMACT and MEMPHYS. But it only alerts on passing above a specified threashold, hence your question, I'm guessing.
However, the memory parameters are stored in RRD files, and the "DS" option in analysis.cfg allows you to set a threshold in either direction. An example might be:
DS memory memory.actual.rrd:realmempct <20 COLOR=yellow TEXT="Memory usage &V% has dropped below &L%"
The "DS" option is used to modify an existing test that is otherwise green. Refer to the "DS" section of analysis.cfg for more information.
