A performance monitor.
Use the docker-compose.yml to start.
You can use your /root/docker-system-performance-monitor/config.json, and the compose file will mount it to the container.
Edit the docker-compose.yml if you want to change the config.json's path.
cpustat can be set only php_cpustat or sysstat
php_cpustat: Use php_cpustat to monitor the cpu. See: https://github.com/catscarlet/cpustatsysstat: Use sar to monitor the cpu. See: https://github.com/sysstat/sysstat
Use docker logs to check the monitor log. Notice that this log didn't show the detail, only a short description about which part(cpu, memory, etc) has performance problems.
Set a email to config.json to receive the detail about your system.
This project use mirrors.aliyun.com as apt's source. Change it if you have a better source.
Memory monitor now only detect your SWAP. If it is more than the last result, it alert.
This project's idea is from my old project https://github.com/catscarlet/system_performance_monitor, but this one use Docker to deploy, much easier!
