acadock-monitoring's Issues

Replace the use of `github.com/facebookgo/grace`

github.com/facebookarchive/grace is deprecated. It should be replaced. From what I remember, this is the same as github.com/cloudflare/tableflip used in git-repository-core, but this is yet to be confirmed.

Docker image is not up-to-date

Latest Docker image available is 0.4.0 whereas the latest version is 0.5.1. This image version is used in the docker-compose.yml from appsdeck-node

[Docker Compose] "host" network_mode is incompatible with port_bindings

With Docker Compose 1.29.2, running this service leads to the error:

docker.errors.InvalidArgument: "host" network_mode is incompatible with port_bindings

This is not the case with Docker Compose 1.25.0.

Ignore first data

Do not send first data and use it only to compute next values

[LoggingMiddleware] Update `github.com/urfave/negroni` from v1 to v3

https://github.com/urfave/negroni/blob/master/CHANGELOG.md

Sometimes CPU usage value is wrong

This service should support authentication

Monitor correctly cgroupv2 paths

When using cgroupv2 on our workstation, metrics are not fetched correctly. We should fix that to have the compatibility with cgroupv1 and cgroupv2

https://docs.docker.com/config/containers/runmetrics/#find-the-cgroup-for-a-given-container

Discussion about that issue: https://scalingo.slack.com/archives/C01L24C2Y2W/p1681916119303509

Add some information about the current node

Add an endpoint to fetch those informations about the node:

Free memory
Available Memory
Swap memory used
CPU usage in percentable
CPU count
Queue length

Sometimes, CPU keeps returning 0 even if there is load

/cpu is not working

Hi people, nice work here! I have been playing with your API, but i'm unable to obtain data for my containers CPU usage. Memory and network usage returns correct data, but cpu is just always at 0 (while docker stats and cAdvisor show the real usage correctly).

My set up:

 docker run -v /sys/fs/cgroup:/host/cgroup:ro         -e CGROUP_DIR=/host/cgroup \
            -v /proc:/host/proc:ro                    -e PROC_DIR=/host/proc \
            -v /var/run/docker.sock:/host/docker.sock -e DOCKER_URL=unix:///host/docker.sock \
            -p 4244:4244 --privileged --pid=host \
            --name acadock -d scalingo/acadock-monitoring

$ docker --version
Docker version 1.5.0, build a8a31ef

An example of the issue:

$ docker ps | grep redis
396e7635c892        redis:3                              "/entrypoint.sh redi   28 hours ago        Up 28 hours         0.0.0.0:6379->6379/tcp   redis

$ docker stats 396e7635c892
CONTAINER           CPU %               MEM USAGE/LIMIT       MEM %               NET I/O

$ curl -L http://localhost:4244/containers/396e7635c892/cpu

And the result is always the same, 0. Even with other containers. Any hint?
