Scout is server monitoring for the modern dev team: automatic monitoring of key metrics, 80+ plugins to monitor your apps, real-time (every second) streaming dashboards, and flexibile alerting.
1. Create a configuration file
2. Run the docker image
Run the scout image, mounting the
scoutd.yml file. Running the image will first download the image, if it is not already locally available.
Run the following command in the directory containing your
docker run -d --name scout-agent \ -v /proc:/host/proc:ro \ -v /etc/mtab:/host/etc/mtab:ro \ -v /var/run/docker.sock:/host/var/run/docker.sock:ro \ -v `pwd`/scoutd.yml:/etc/scout/scoutd.yml \ --net=host --privileged scoutapp/docker-scout
Reading host metrics
We want to look at resources on this host, not this container.
server_metrics Ruby gem used by the scout agent primarily looks at the
/proc directory, but, if available, will instead read from
/host/proc, which is expected to be shared from the host when running the container (see the above command sample).
server_metrics gem will also default to reading from
/host/etc/mtab (also mounted above), if it exists, to determine the drives mounted on the host. It will recognize theses hosts inside the container if they are mounted by UUID (
--net=host flag will allow gathering network metrics from the host.
--privileged flag will allow gathering the disk capacity metrics from the host.
scoutd config options
Any option may be set in the provided scoutd.yml file. This file must be world-readable and mounted to
/etc/scout/scoutd.yml (see above command).
For a list of options, see our scoutd help page.
Monitoring Docker Containers
Monitor the resource usage of your running containers with our Docker Monitoring Plugin.
The plugin requires reading from
/host/sys/fs/cgroup (mounted above). This mounting is unnecessary if the docker plugin will not be in use.
