After changing the rules file, you'll need to trigger a prometheus reload, either by hitting a special API endpoint or sending it a SIGHUP. See https://prometheus.io/docs/prometheus/latest/management_api/#reload
(Note: *don't* restart the prometheus process! That's a much slower operation as it has to dump out and reload its WAL and can take several minutes on a busy server) On Tuesday, 28 February 2023 at 06:55:24 UTC inmar tzemach wrote: > Thanks! > > How can I change the threshold from outside for giving expression while > Prometheus running? > > On Monday, February 27, 2023 at 5:06:27 PM UTC+2 Brian Candler wrote: > >> No, but you can expand the rules files using a preprocessor of your >> choice. >> >> If you want the threshold to be different for different time series, then >> see https://www.robustperception.io/using-time-series-as-alert-thresholds >> >> On Monday, 27 February 2023 at 13:58:47 UTC inmar tzemach wrote: >> >>> Is it possible to add parameters in rules files expression? >>> Something like: >>> expr: (100 - (avg by (instance) >>> (irate(node_cpu_seconds_total{mode="idle"}[5m])) * 100)) > {{ $treshhold}} >>> >>> Thanks >>> >> -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
