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.
0-value
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
