Connect Grafana to Azure Log Analytics

Log Analytics

In this post I demonstrate how to connect Grafana to Azure Log Analytics using the Azure Monitor data source plugin. Grafana is an open source, data visualization and monitoring platform.  Or, as the website states “The open platform for beautiful analytics and monitoring”.  Grafana can run on Windows, Linux, ARM, as well as Docker.  There is a hosted option for those who prefer to have someone else host the environment.

Alerts Based on Rolling Averages in Log Analytics

This post will go over how to create an alert for Log Analytics that evaluates two recent time periods for comparison. It’s a little, let’s say, “in depth” as far as Log Analytics queries go. The alert is intended to trigger when a variable threshold is met based on the recent baseline as opposed to a static metric. Used with my PingTimeLog tool found here, alerts can be triggered if recent response time goes over a rolling average value. I also include a disk free space alert to identify when a large amount of data is added to a disk.
