Doing Deadman Checks With Prometheus Metrics in MetricsQL

Sun, 19 Oct 2025 17:44:39 +0000

The lack of functionality to do deadman checks is one of my biggest gripes with PromQL. Fortunately, MetricsQL (a superset of PromQL) has added this functionality, and it’s very easy to use. If you’re not familiar with MetricsQL, it’s the built in query language in VictoriaMetrics, a horizontally scalable time series database. VictoriaMetrics is my go to database for storing Prometheus metrics because of how performant and easy to use it is compared to alternatives like Mimir or Thanos.

With the expanded feature set that InfluxDB V2 offers, many want to upgrade their existing V1 InfluxDB installations. The issue is that there are a lot of incompatibilities between V1 and V2. Any of your systems writing to InfluxDB, like Telegraf, will need to be updated to use the new influxdb_v2 plugin, since this new version comes with token based authentication instead of user based authentication. The query language is also different in V2, which spells trouble if you have something like Grafana set up. Even the intern doesn’t want to rewrite every panel in every dashboard to use the Flux language instead of InfluxQL.
