Hi,
I have a metric which sends data only in case of a specific event. In
other words, it will not have regular continuous telemetry every 15
seconds, but it will be there for a single data point. Now, I
configured an alert to check if the metric exists (did not include any
'for' condition in the rule as there is no need to wait), an alert
should trigger. What is happening is that when the metric becomes
available in Prometheus, the rule gets activated to yellow, but
instead of firing, it automatically goes away within 15 seconds. Is
there some additional setting I have to do to alert on event based
metric which lasts for only 1 single datapoint or 15s ?
As Brian mentions the metric should continue to exist, rather than
regularly disappearing. Normally you would use a counter which is
incremented every time an event happens. Are you using one of the
Prometheus client libraries, as these should make it very easy to setup?
