Observation¶

Graphs on https://stats.openqa-monitor.qa.suse.de/d/7W06NBWGk/job-age?orgId=1&from=now-30d&to=now show negative values. That leads to Grafana appending "ago" to durations displayed at the very top of the dashboard. You can also see the negative values if you select the table view in edit mode of the affected graphs/panels. I think all panels that are using one of the job_age_p* fields are affected.

Acceptance criteria¶

• AC1: Negative values are no longer written to the job_age_p* fields so the graphs/panels using them don't show "ago" or negative values in the table view anymore (because it makes no sense for an age to be negative).

Suggestions¶

• Checkout the Telegraf config for how those values are computed and fix the computation

Out of scope¶

• Fixing/removing negative values that are already in InfluxDB (although it may be worth a try if it is easy)
