Why is line not visible on graph?

[nicholastripp]

Grafana 8.5.4

Expect to see the line. Hovering shows the value.

Trying to graph process metrics and get usable name and associate with service name.

old query (running a forked version of wmi_exporter that uses a wmi call to rename the process names to the service name)

sum by (process)(rate(wmi_process_cpu_time_total{process=~"$PROCESS_VAR"}[1m]))

new:

sum((rate(windows_process_cpu_time_total{}[1m])) 
* on(instance, process_id) group_left(name, display_name, run_as) windows_service_info{display_name=~"$PROCESS_VAR"}) 
without (mode,process_id)

There is a connect null configuration, might that help?

[nicholastripp]

you can see above 3.85 is the value. it is not null. no graph line is created

[yosiasz]

where is the next value. the connect null configuration is for when there is a gap between one value in time series to the next

[nicholastripp]

i tried your suggestion. did not help

Seems something going on with thanos … craziest thing. When i search for 1 hour 1 data point shown. When i search 6 hours one data point shown at different time. The 1 hour being part of 6 both should show.
