Files

• bin/metrics-cgroup.sh
• bin/metrics-cgroup.rb

Usage

Collect all cgroup metrics, tested only on CentOS.

metrics-cgroup.rb -g "/sys/fs/cgroup/**/**"

Collect only systemd service metrics

metrics-cgroup.rb -g "/sys/fs/cgroup/**/system.slice/*"

Collect only user.slice only

metrics-cgroup.rb -g "/sys/fs/cgroup/**/user.slice"

Collect only mesos task metrics

metrics-cgroup.rb -g "/sys/fs/cgroup/**/mesos/*"

Collect only docker container metrics (may not be meaningful if you already collect metrics from docker)

metrics-cgroup.rb -g "/sys/fs/cgroup/**/docker/*"

Collect only system.slice, user.slice, docker and mesos and nothing else

metrics-cgroup.rb -g "/sys/fs/cgroup/**/{system.slice,user.slice,docker,mesos}{,/*}"

Instead of collecting breakdown of each docker instance, or mesos task, or systemd service metric; this could let to collect/compare overall docker, mesos, systemd and user recources in total.

metrics-cgroup.rb -g "/sys/fs/cgroup/**/{system.slice,user.slice,docker,mesos}"

sensu-plugins-cgroups's Issues

Dependabot can't resolve your Ruby dependency files

Dependabot can't resolve your Ruby dependency files.

As a result, Dependabot couldn't update your dependencies.

The error Dependabot encountered was:

Bundler::VersionConflict with message: Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    bundler (~> 1.7)

  Current Bundler version:
    bundler (2.2.15)

Your bundle requires a different version of Bundler than the one you're running.
Install the necessary version with `gem install bundler:1.17.3` and rerun bundler using `run.rb _1.17.3_`

If you think the above is an error on Dependabot's side please don't hesitate to get in touch - we'll do whatever we can to fix it.
