No data in the Grafana about dex

[0xERR0R]

Grafana loads data from prometheus. If you see the data in the Prometheus UI, it could be the communication problem between Prometheus and Grafana. Is 10.2.14.252 reachable from Grafana?

[panks21]

It is reachable. Grafana is pulling data from same prometheus for other apps like blocky / node-exporter
Here are the versions if it helps
Grafana - 8.4.2
Prometheus - 2.33.4

[panks21]

There is some issue with the query. If I run the same query in Prometheus UI, I get error as well.
count(dex_container_running{container_name=~"$container"})

In above query, it doesn't like the variable $container

There is data in Prometheus

dex_container_running{container_name="blocky", instance="10.2.14.252:8386", job="dex-Dietpi314"}

Did you create your dashboard by importing of this file: https://github.com/0xERR0R/dex/blob/master/docs/grafana8.json ?

[panks21]

Yes that one as well as the new grafana8 dashboard... I have both but "No Data" in both of them

Do you have "dex_block_io_read_bytes" metric values in prometheus?

[panks21]

No Following is what I have

[0xERR0R]

Please try to change the variable container (Dashboard settings -> variables -> conainer): set "dex_memory_usage_bytes" as query:

[panks21]

Perfect..
This works.. thanks for the tip.

[0xERR0R]

dex doesn't export the "dex_block_io_read_bytes" metric. Do you see some block I/O values if you execute "docker stats" on the machine?

[panks21]

Yes I do

[0xERR0R]

That looks good. Do you have any errors in the log output? Maybe the same reason as described in #22?

[panks21]

No errors reported in the logs. Thats all I have in the docker logs

time="2022-03-10T15:05:29Z" level=info msg="Server is ready to handle requests at :8080"

[0xERR0R]

can you try the latest version please? This should report "dex_block_io_read_bytes"

[panks21]

Indeed. It is reporting "dex_block_io_read_bytes"

[0xERR0R]

Ok, that means, the original version of the dashboard should work now on your system

[panks21]

Yup!
I reverted back to the original settings.. it is working

[0xERR0R]

fixed via #22
