elasticsearch stack monitoring on kubernetes(ECK)

UPDATE: Since ECK operator 1.7 there is a new way to deploy stack monitoring. I’ve added the section at the end to cover for this. The old method still works and depending on your use case you can still use the old method versus new. The main difference between the OLD and NEW is that the OLD method uses filebeat and metricbeat pods while the new method uses filebeat and metricbeat sidecar containers. Lets get started with monitoring your elastic stack in kubernetes. There are multiple ways of doing this and I will divide this up into 3 sections, using… Continue Reading

elasticsearch 8.x configure roles and users for stack monitoring

A lot of changes were made with elasticsearch 8.0 release but the main one that affected me the most was the ability to use the default elastic(superuser role) to access system indices. According to https://www.elastic.co/guide/en/elasticsearch/reference/current/release-highlights.html#_better_protection_for_system_indices we no longer have write access to system indices with the superuser role. When configuring stack monitoring using metricbeats this is an issue if you’ve been just using the elastic user to configure the monitoring. You can add allow_restricted_indices to the role to enable it back however its the lazy and insecure method. I’ve summarized the creation of roles and users for metricbeats and filebeats… Continue Reading

How to run setup for various beats(filebeat, metricbeat, & more) in kubernetes to load dashboards and more

Whenever you install beats or update beats its best if you run the setup so that the setup will update your index templates, ILM, visualizations, etc. I found that its always best before installing or upgrading to use a seed host to just run the setup before deploying or updating across your environment and to turn off template updates and dashboard loading on the beats locally so that your elasticsearch cluster is not flooded. In a baremetal environment this is easy to do but in docker and in kubernetes it gets a bit difficult. Sure you can setup a initContainer… Continue Reading
