Accordingly, have alerts to ensure that Prometheus servers, Alertmanagers, PushGateways, and other monitoring infrastructure are available and running correctly. As always, if it is possible to alert on symptoms rather than causes, this helps to reduce noise. For example, a blackbox test that alerts are getting from PushGateway to Prometheus to ...

10.12.2014 · Currently if Prometheus restarts, we lose the 'for' state for firing alerts. While this isn't an issue for short for clauses, it presents a problem for clauses that are in the hours to days range. It'd be good to persist this state in some way, so that alerts don't have to start again from scratch. We probably don't want to count the time the ...

This can be used for alerts adjustments and debugging (the user has an overview of what pending alerts occurred recently and when). Used metrics: The dashboard uses two synthetic Prometheus time series: ALERTS and ALERTS_FOR_STATE. Dependencies: Prometheus 2.4.0 (added ALERTS_FOR_STATE metric)

For pending and firing alerts, Prometheus also stores synthetic time series of the form ALERTS{alertname="<alert name>", alertstate="<pending or firing>", <additional alert labels>}. The sample value is set to 1 as long as the alert is in the indicated active (pending or firing) state, and the series is marked stale when this is no longer the case.

Prometheus: understanding the delays on alerting 16 Nov 2016 by Marco Pracucci Comments. Prometheus is a great monitoring and alerting system. At Spreaker (self promotion - we’re hiring!) we’re slowly migrating to Prometheus, and thus a correct understanding in how it works is very important.. Today, me and my colleague Rocco were experimenting on the delays introduced …

Alerting rules. Alerting rules allow you to define alert conditions based on Prometheus expression language expressions and to send notifications about firing alerts to an external service. Whenever the alert expression results in one or more vector elements at a given point in time, the alert counts as active for these elements' label sets.

ALERTS_FOR_STATE is a newly added Prometheus-internal metric that is used for restoring alerts after a Prometheus restart.

At each evaluation cycle, Prometheus runs the expression defined in each alerting rule and updates the alert state. An alert can have the following states: inactive: the state of an alert that is neither firing nor pending; pending: the state of an alert that has been active for less than the configured threshold duration; firing: the state of an alert that has been active for longer than the configured threshold duration
