[Bug]: Temperature alerts break in v1.45
kmlucy opened this issue · comments
Bug description
Several of my alerts for temperatures break in v1.45. The temperature the alert is reading is normal, but the alert itself is an order of magnitude high:
v1.44.3 works as expected, v.45.3 has this issue.
Expected behavior
Alerts get correct values from charts
Steps to reproduce
- Create alerts as shown below
- Update to v1.45
Installation method
docker

Hi, @kmlucy. The foreach option was deprecated. It was mentioned in the v1.45.0 deprecation notice.
Added "wontfix" because there is no problem with the health engine.
Collectors should be updated - create a chart per instance instead of a dimension per instance.
Added go.d/hddtemp and go.d/sensors: both create a chart per instance. foreach is not needed, filtering/selection can be applied using chart labels.
@ilyam8 Thank you for updating those so quickly. Is it possible to do the same thing for smartd? It also creates a dimension per drive instead of a chart.
Yes, we need to rewrite smartd as well. I am thinking of dropping reading smartd logs instead of just executing the binary and parsing the response.
@ilyam8 Thank you for updating those so quickly. Is it possible to do the same thing for smartd? It also creates a dimension per drive instead of a chart.
Smartd was rewritten too - go.d/smartctl.
Thank you for fixing that so quickly. These updates will come in v1.46?
Yes.
