PromQL is a powerful language to query metrics, but it could be challenging for beginners. To ease the learning curve of PromQL, Sysdig provides a set of curated examples, called PromQL Library. It helps you perform complex queries against your metrics with one click and get insight into your infrastructure problems which was not previously possible with Sysdig querying. For example, identify containers > 90% limit and counting pods per namespace, and so on.
You have the following categories currently to experiment with PromQL:
