Hopefully I chose the right forum for my issue.
We’re running the check_disk command on several hosts. The check gives a return value of free disk space and also performance data of used disk space. Both together don’t add up to 100%.
For an example look here:
You can see that there are 9% free disk space (which is correct - looking at df -h). It also shows that there are 85% of space occupied which adds up to 94%. We are using Grafana with InfluxDB to visualize stuff easier and since the value of used disk space equals the 85% the free value displayed in Grafana is off by a few percent.
Do I miss something obvious here? Is this supposed to look like this or did I run into a bug?
