Bug: Zero (0) values not displayed correctly
lw-mgr opened this issue · comments
Abstract
Zero values (0) will not result in a data point in grafana. The graph will falsely display the last received value greater than zero.
In CheckMK the graph displays the 0 value correctly.
Steps to reproduce
- Add CheckMK Check which will could have 0 values (e.g. using fileinfo.groups to count files in a directory, it could be a valid case that the directory is empty)
- Add grafana table panel and use this newly created checkmk service check as datasource
- Grafana only displays rows having value greater than 0
Versions
- Grafana 6.5.2
-- CheckMK Plugin 1.1.0 - CheckMK 1.6.0p7 Enterprise
I can confirm I'm having the same issue.
Grafana 7.0.0
--CheckMK Plugin 1.1.0
