Best practices to prevent alert fatigue

As your environment changes, new trends can quickly make your existing monitoring less accurate. At the same time, building alerts after every new incident can turn a straightforward strategy into a convoluted one. Treating monitoring as a one-time or reactive effort can both result in alert fatigue. Alert fatigue occurs when an excessive number of alerts are generated by monitoring systems or when alerts are irrelevant or unhelpful, leading to a diminished ability to see critical issues. Updating your alerts infrequently or too often can cause false positive alarms and redundant alerts that overwhelm your team. A desensitized team won’t be able to detect issues early and will lose trust in their monitoring systems, which can disrupt production and negatively impact your business.

The good, the bad and the ugly of templating YAML in Kubernetes

In this blog post, I’d like to argue that templated YAML has a bad reputation in the Kubernetes community for the wrong reasons, and that it actually is not as evil as one might believe, even with the bad experiences that all of us have likely made in the past.
