I just built TICK setup and it seems pretty sweet! I was especially interested in the ability to set thresholds on specific metrics.
Via Chronograf, I setup a Kapacitor rule to alert on /var where used_percent > 90% (since I knew I had a machine that was almost full).
As soon as I enabled the script, it kept alerting every 20 seconds (the interval time I have set on telegraf).
Is this normal? Is there a way to only trigger when a threshold is met and then only trigger when the threshold is cleared?
