pmm 一些问题记录 | 易学教程

安装

 yum -y  install docker
 systemctl start docker
 docker pull percona/pmm-server:1
 docker create    -v /opt/prometheus/data    -v /opt/consul-data    -v /var/lib/mysql    -v /var/lib/grafana    --name pmm-data    percona/pmm-server:1 /bin/true
 docker run -d    -p 80:80    --volumes-from pmm-data    --name pmm-server    --restart always    percona/pmm-server:1

修改配置，主要修改pmm 数据默认保留时长：

 进入docker：
 
 vi /etc/supervisord.d/pmm.ini 
 
 --storage.local.retention=120h
 --storage.tsdb.retention=120h
 
 需要重启docker

mysql pmm库占用空间问题，系统空间使用100%

agent_log、query_class_metrics、query_global_metrics表，直接truncate 过了一段时间，还是没有数据
尝试重启一个客户端,在进行观察，就有数据了：
pmm-admin restart --all

pmm 监控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 监控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
