修改配置，主要修改pmm 數據默認保留時長：
進入docker： vi /etc/supervisord.d/pmm.ini --storage.local.retention=120h --storage.tsdb.retention=120h 需要重啓docker
mysql pmm庫佔用空間問題，系統空間使用100%
agent_log、query_class_metrics、query_global_metrics表，直接truncate 過了一段時間，還是沒有數據 嘗試重啓一個客戶端,在進行觀察，就有數據了： pmm-admin restart --all
pmm 監控mysql
rpm -ivh pmm-client-1.17.2-1.el7.x86_64.rpm pmm-admin config --server <serverip>:<server port> pmm-admin add mysql --user pmmuser --password pmmpassword
pmm 監控mongo
rpm -ivh pmm-client-1.17.2-1.el7.x86_64.rpm pmm-admin config --server <serverip>:<server port> pmm-admin add mongodb --cluster <cluster tag> 非正常端口比如端口32000 pmm-admin add mongodb --cluster <cluster tag> --uri 127.0.0.1:32000
