dex_block_io errors while serving metrics

I ran the container with docker-compose as the readme file, but when I run curl on the port, I get the following:

An error has occurred while serving metrics:

38 error(s) occurred:
* collected metric "dex_block_io_read_bytes" { label:<name:"container_name" value:"node-exporter" > counter:<value:1.292288e+07 > } was collected before with the same name and label values
* collected metric "dex_block_io_write_bytes" { label:<name:"container_name" value:"node-exporter" > counter:<value:0 > } was collected before with the same name and label values
* collected metric "dex_block_io_read_bytes" { label:<name:"container_name" value:"prometheus" > counter:<value:4096 > } was collected before with the same name and label values
* collected metric "dex_block_io_write_bytes" { label:<name:"container_name" value:"prometheus" > counter:<value:4096 > } was collected before with the same name and label values
.......

And it continues having the same errors for those 2 metrics on the rest of my containers.

Emitting metrics for cpu usage seconds

For my home lab, I've got a few layers of virtualization involved (Proxmox, LXC, Docker, etc.). Measuring the CPU usage percent in my situation doesn't easily surface the overall system utilization being consumed by containers. Instead, having metrics for CPU usage seconds like what cadvisor also emits would be more usable in my situaiton.

I still see the benefit of CPU usage percent, such as detecting if a container has constrained resources. ps: dex is awesome! It's great to use it as opposed to cadvisor.

Error -- client version 1.41 is too new

Trying this on a new centos 7.9 machine. But I get following error

docker logs -f dex
time="2022-05-13T14:27:56Z" level=info msg="Server is ready to handle requests at :8080"
time="2022-05-13T14:28:10Z" level=error msg="can't list containers: Error response from daemon: client version 1.41 is too new. Maximum supported API version is 1.37"
time="2022-05-13T14:28:25Z" level=error msg="can't list containers: Error response from daemon: client version 1.41 is too new. Maximum supported API version is 1.37"
time="2022-05-13T14:28:40Z" level=error msg="can't list containers: Error response from daemon: client version 1.41 is too new. Maximum supported API version is 1.37"

I even tried to export 1.37 as the API version but still no luck
export DOCKER_API_VERSION=1.37

docker --version
Docker version 18.03.1-ce, build 9ee9f40

Anything we can do to fix this??

IO write and read always zero

Hi, does anyone know if I need to change something to be able to read this data?

Grafana 8 Dashboard

Hi i am a somewhat new and somewhat happy dex user :)
And it so happened that I created my own Grafana dashboard based on the latest Grafana 8 panels. I would be happy to share those if you are interested?

Kind regards

No data in the Grafana

Queries on Prometheus work fine but when I am trying to get the Grafana dashboard working, I see no data for each and every chart. The grafana docker logs reports this as one of the errors

logger=tsdb.prometheus t=2022-03-02T05:02:15.29+0000 lvl=eror msg="Exemplar query failed" query="count(dex_container_running{container_name=~"()"}) by (container_name)" err="Get "http://10.2.14.252:9090/api/v1/query_exemplars?end=1646197200&query=count%28dex_container_running%7Bcontainer_name%3D~%22%28%29%22%7D%29+by+%28container_name%29&start=1646186400\": context canceled"

Any inputs??
