I used: Icinga2, Grafana, influxDB and snmpV3.
All work good ^^ (thanks to you).
For example, I want to have the SLA on the port 9200 (elasticsearch).
So i already can graph it, but my graph if from 9200 to 0 (it’s logical).
If I stop the service elasticsearch, the port goes to 0 (it’s normal too).
And on grafana, if i control the “average” i can will have a value between 9200 and 0 (4600 if i stop the service half time).
So now, the question: is it possible on Grafana to convert 9200 (the max value on the scale) to binaries value (0 to 1) or percent value (0 to 100).
If it’s not possible, i will do a script like:
If port = 9200, then echo 100, else echo 0, fi
And of course, I will have 100 or 0… But if you do that on Grafana that can be useful.
