Collect Stats
The collect_stats script periodically checks resource usage for all users using the docker stats command.
For each user, data is logged within their respective folder in JSON files, located in the /usr/local/panel/core/stats/ directory.
By default, the script is configured to operate in the background at 60-minute intervals using a cronjob:
0 * * * * opencli docker-collect_stats
To modify the script's execution time, edit the crontab and adjust the cron schedule as needed to specify the desired execution frequency for the script.
To initiate the manual data collection process, execute the following command:
opencli docker-collect_stats
Example:
# opencli docker-collect_stats
Data for stefan written to /usr/local/panel/core/stats/stefan/2023-10-08-09-33-56.json
{"cpu_percent": 0.81, "mem_percent": 13.38, "net_io": "240.5k", "block_io": "409.2k"}
Data for radovan written to /usr/local/panel/core/stats/radovan/2023-10-08-09-33-56.json
{"cpu_percent": 0.01, "mem_percent": 0.02, "net_io": "50.59k", "block_io": "0"}
:::info
