In our sample database environment, we use this article link to install HAProxy 2.5.5 from the source code.

ENJOY!Īs shown in the sample database environment, we have 3 database servers running as a cluster. Once done, you can use the provided link and the custom port to log in and change the default password. If this is the case, Chrome users may want to type 'thisisunsafe' to bypass the warning. Note: Some browsers may not trust the default SSL certificate when you first open one of the urls above. The default username is 'admin' and the password is 'admin' :) You can access your new server using one of the following web addresses: PMM Server has been successfully setup on this system! Use the following command if you ever need to update your container by hand:ĭocker run -d -p 8443:443 -volumes-from pmm-data -name pmm-server -restart always /percona/pmm-server:2 Gathering/downloading required components, this may take a momentĬhecking docker installation - installed. #get percona images from docker hubĭocker pull /percona/pmm-server:2 For us, we are using the following command to get it done. Use this link for the easy install script method provided by the Percona team or you can try another setup method based on your environment. INSTALL PERCONA MONITORING AND MANAGEMENT SERVER (PMM SERVER) Docker installed on monitoring host act as PMM server.ġ.Docker installed on database cluster (Master, and 2 Standby) which is used to expose statistics or matrics of Pgbouncer, the pooling of each database cluster. In our experiment, we have set up Percona Monitoring and Management Server using docker and monitor 3 services PostgreSQL, PgBouncer, and HAProxy as shown in the below sample database environment architecture. By choosing a tool such as Percona we believe it will help the productivity and efficiency of your monitoring task. Database administrators can choose to monitor databases manually, but this choice is a time-consuming and inefficient approach. We have to do database monitoring to find out database issues in time, which can help the application/system remain healthy and accessible. PMM collects performance metrics from databases and other supported services, then show visualized data in the web UI dashboard.Explore patterns in their behavior, troubleshoot, and perform database management tasks anytime.Allows users to observe the health of their database systems.The official website below shows the significant functionalities of PMM (Percona Monitoring and Management). In this article, we will introduce a tool called " Percona Monitoring and Management" which is an open-source database monitoring, management, and observability solution for popular databases available in the market such as MySQL, PostgreSQL, and MongoDB.
