Docker Plugin
This module keeps track of Docker instances on your machine. The module uses the Docker stats command to retrieve the statistics.
Metrics
- Memory usage
- Total memory
- Network in
- Network out
- Disk write
- Disk read
- CPU usage
- Docker container count
Dependencies
The agent360
user needs sudo access to run Docker stats. Open the /etc/sudoers
file and append the following at the end of the file.
agent360 ALL=(ALL) NOPASSWD: /usr/bin/docker
This command assumes that docker
exists in in /usr/bin/docker
.
Configure the plugin
To enable the plugin, edit the /etc/agent360-custom.ini
file and add the following lines:
[docker]
enabled = yes
Test the plugin
Run the sudo -u agent360 agent360 test docker
command to see if everything is installed correctly.
dockerdocker:
{
"containers": 2,
"goofy_lewin":
{
"cpu": "0.00",
"disk_in_bytes": 0,
"disk_out_bytes": 0,
"mem_pct": "0.05",
"mem_total_bytes": 1040501964.8,
"mem_usage_bytes": 483328.0,
"net_in_bytes": 0,
"net_out_bytes": 0
},
"pensive_austin":
{
"cpu": "0.00",
"disk_in_bytes": 0,
"disk_out_bytes": 0,
"mem_pct": "0.05",
"mem_total_bytes": 1040501964.8,
"mem_usage_bytes": 483328.0,
"net_in_bytes": 0,
"net_out_bytes": 0
}
}
Now you can restart the agent with the service agent360 restart
command.
