Hi! I’m using grafana with prometheus+cAdvisor and want to create a panel with information about containers state.
My query: time() - container_start_time_seconds{image="my_image"}
and legend : {{instance}} because i will have multiple targets in prometheus.
The problem is that if cAdvisor hasn’t information about my_image container - it returns nulls:
Left side is time, right - value.
I want to fill these nulls with zeroes.
I changed units to duration (d hh:mm:ss) and made a value mapping:
Special → Null → 123 → orange (123 for test).
This is how query response looks like now when formatted. And how graph looks:
This gap has no values still. How can I fill it?
The No Value: What to show when there is no value option doesn’t do anything too.
