In order to monitor a database’s tablespaces I have time series like the following:
To build alerts,
1- first I have a simple query named insMetric:
2- then a reduce expression on insMetric called insMin:
3- and finally a math expression, on insMetric, called insAlert:
$insMin > 20
This works fine but there’s just one threshold, 20, for all series. I would like to have multiple thresholds in a single alert rule, let’s say 20 for SYS and 25 for SYSTEM. Is this possible? How?
