It guarantees graphic visibility of the data (thanks to the Grafana frontend) and it is very important that the data stored is useful. I’ll give you an example of how simple it can be to produce obsolete data in Influx: Suppose I create a…

Monitor Cluster Disk Space with Icinga2

The Problem If you’re trying to monitor a Microsoft Cluster, you’ll surely want to monitor the disk space of a single cluster service. In this case there’s a problem with Icinga2 Agent:  you can’t use it with more than one IP address.  So you can’t simultaneously monitor the resources of the “physical” host and a…

We often hear about predictive monitoring, alongside the words machine learning and anomaly detection. Today, just as in the past, the “data” is invaluable and what we will try to do here is use simple data we can easily collect (data which individually might have no value) and apply Machine Learning techniques in order to identify anomalies, and then…
