Node exporter 0.16.0 is out, and with some big changes. Let’s take a look.
You may have come across a mBean attribute with a value such as STARTED or RUNNING. How do you convert that to a more useful boolean metric?
While the JMX attributes you are usually working with will be numbers, the JMX exporter also has support for strings.
When using the count aggregation operator you may have noticed that it sometimes returns nothing rather than 0. Why is this?
Wouldn’t it be nice to have arbitrary locations on the Worldmap panel?
The Worldmap Panel for Grafana allows displaying of metrics on a map.
You may have noticed that notifications from the Alertmanager are text. Wouldn’t it be nice if Prometheus sent graphs along?
If your applications are restarting regularly, whether due to segfaults or OOMs, it’d be nice to know.
Prometheus 2.2.0 is now out, following on from 2.1.0 back in January with several fixes and improvements.
Worried that your application metrics might suddenly explode in cardinality? sample_limit can save you.
