Prometheus doesn't have an explicit boolean type or functionality. However there is a convention and enough power in PromQL to work with booleans.
The Prometheus client library guidelines recommend having a Child

. Why?
There's so many monitoring systems out there these days that it's difficult to figure out what's actually different, and what just has a different name or falls under a different concept.

A handy feature of the Alertmanager is that almost all notification fields are templatable. This can be used to route emails based on labels.
As I mentioned in a previous post, I made some memory-related improvements to Prometheus that'll be in the 1.5 release. Let's look at how I came across unneeded memory allocations and ultimately improved the code.
There's various ways Prometheus federation can be used. To ensure your monitoring is scalable and reliable, let's look at how to best use it.
It can be a little confusing to figure out Prometheus memory usage. Let's break part of it down.
A common question around Prometheus client libraries is how much RAM they'll use on a busy process. There tends to be disbelief when we say it's the same as an inactive server. Let's look deeper.
