      Percona (PMM) One-Click App

      Percona Monitoring and Management (PMM) is an open-source tool which provides a GUI powered by Grafana for monitoring and managing MySQL, MariaDB, PostgreSQL, and MongoDB databases. You can use PMM to easily observe important metrics, logging, and statistics related to your databases and the hosts they run on. Additionally, it includes a number of tools which can help to optimize your database’s performance, manage all database instances, and track and identify potential security threats. Linode’s Percona (PMM) One-Click App deploys a Linode with PMM installed and ready for you to begin monitoring your databases.

      PMM Architecture Overview

      The PMM tool uses a client-server model which makes it easy to scale monitoring across several databases hosted on various remote hosts. See the table below to better understand how each PMM component fits into the context of Linode’s Percona (PMM) One-Click App.

      PMM ServerThe Percona (PMM) One-Click App deploys an instance of the PMM Server, which includes the Grafana web interface to visualize all the data collected from the databases it monitors.
      PMM ClientYou will need to install the PMM Client on any Linode that hosts a database that you would like to monitor. The PMM Client will help you connect to the PMM Server and relay host and database performance metrics to the PMM Server.


      Deploy a Percona (PMM) One-Click App

      Linode’s One-Click App Marketplace allow you to easily deploy software on a Linode using the Linode Cloud Manager. To access Linode’s One-Click App Marketplace:

      1. Log in to your Linode Cloud Manager account.

      2. From the Linode dashboard, click on the Marketplace button in the left-hand navigation menu.

      3. The Linode creation page will appear, with the One-Click and Marketplace tabs pre-selected.

      4. Under the Select App section, select the app you would like to deploy:

        Select a One-Click App to deploy

      5. Once you have selected the app, proceed to the app’s Options section and provide values for the required fields.

      Percona (PMM) Options

      HostnameThe hostname to assign to your new Linode. Required.

      Linode Options

      The following configuration options are possible for your Linode server:

      Select an ImageDebian 10 and Ubuntu 20.04 are currently the only images supported by the Percona (PMM) One-Click App. Required.
      RegionThe region where you would like your Linode to reside. In general, it’s best to choose a location that’s closest to you. For more information on choosing a DC, review the How to Choose a Data Center guide. You can also generate MTR reports for a deeper look at the network routes between you and each of our data centers. Required.
      Linode PlanYour Linode’s hardware resources. Percona recommends roughly 1 GB of storage on your PMM Server for each database node you would like to monitor. For more information on Percona’s system requirements see their official documentation. If you decide that you need more or fewer hardware resources after you deploy your app, you can always resize your Linode to a different plan. Required.
      Linode LabelThe name for your Linode, which must be unique between all of the Linodes on your account. This name will be how you identify your server in the Cloud Manager’s Dashboard. Required.
      Root PasswordThe primary administrative password for your Linode instance. This password must be provided when you log in to your Linode via SSH. It must be at least 6 characters long and contain characters from two of the following categories: lowercase and uppercase case letters, numbers, and punctuation characters. Your root password can be used to perform any action on your server, so make it long, complex, and unique. Required.

      When you’ve provided all required Linode Options, click on the Create button. Your PMM app will complete installation anywhere between 1-5 minutes after your Linode has finished provisioning.

      Software Included

      The Percona (PMM) One-Click App will install the following required software on your Linode:

      DockerDocker is used to containerize PMM.
      GrafanaGrafana is the visualization tool used by PMM to provides charts, graphs, and alerts for the databases that are being monitored.
      pmm-adminpmm-admin is a command-line tool used to manage PMM Clients.


      Currently, Linode does not manage software and systems updates for One-Click Apps. It is up to the user to perform routine maintenance on software deployed in this fashion.

      Getting Started after Deployment

      Access your PMM Server’s Grafana Dashboard

      After the PMM Server has finished installing, you will be able to access its Grafana dashboard over http:// and your Linode’s IPv4 address. To find your Linode’s IPv4 address:

      1. Click on the Linodes link in the sidebar. You will see a list of all your Linodes.

      2. Find the Linode you just created when deploying your app and select it.

      3. Navigate to the Networking tab.

      4. Your IPv4 address will be listed under the Address column in the IPv4 table.

      5. Copy and paste the IPv4 address into a browser window. Ensure you are using http://.

      6. You will see the PMM Home Dashboard actively monitoring your server:

      Installing the PMM Client

      To begin monitoring a database node, you will need to install the PMM Client on the Linode that hosts your database and connect the node to the PMM Server.


      The PMM Server deployed with Linode’s Percona (PMM) One-Click App is compatible with PMM Client version 1.
      1. Connect to your Linode via SSH.

      2. Update your system’s software.

        Debian or Ubuntu:

        sudo apt-get update && apt-get upgrade


        sudo yum update
      3. Install the PMM Client (version 1):

        Debian or Ubuntu:

        sudo apt-get install pmm-client


        sudo yum install pmm-client
      4. Connect your database node to the PMM Server. Replace with your PMM Server’s IPv4 address.


        sudo pmm-admin config --server

        Once complete, you should see a similar output:

        OK, PMM server is alive.
        PMM Server      |
        Client Name     | li222-111
        Client Address  |

      Monitor a Database Instance

      Once your database node and your PMM Server are communicating, the final step is to add your database instance to be monitored by your PMM Server. These steps are completed on your Database node.

      1. Connect to your Linode via SSH.

      2. Add your database instance to be monitored by your PMM Server. This command will add a MySQL database instance to be monitored. You can replace mysql with the database type that your node is hosting (i.e. postgresql or mongodb). See Percona’s Managing PMM Client documentation for details.

        pmm-admin add mysql

        Your Percona dashboard should now be monitoring your MySQL service.


      Next Steps

      The Percona Monitoring Management Tool is very powerful and can be configured to monitor and display various pieces of your database instances. Once you have completed the basic configurations outlined in this guide, you should review Percona’s documentation to learn more about the PMM tool. Here are some suggested topics:
