Get started with PMM¶

To get up and running with Percona Monitoring and Management (PMM) in no time, install PMM on Bare Metal/Virtual using the Easy-install script for Docker.

This is the simplest and most efficient way to install PMM.

Alternative installation options

For alternative setups, explore the additional installation options detailed in the Setting up chapter:

Prerequisites¶

Before you start installing PMM, verify that your system meets the compatibility requirements.

Verify system compatibility

Disk: Approximately 1 GB of storage per monitored database node with data retention set to one week. By default, retention is 30 days.
Memory: A minimum of 2 GB per monitored database node. The increase in memory usage is not proportional to the number of nodes. For example, the data from 20 nodes should be easily handled with 16 GB.
Ports: Your system’s firewall should allow TCP traffic on port 443.

Install PMM¶

The Easy-install script only runs on Linux-compatible systems. To use it, run the command with sudo privileges or as root:

Download and install PMM using cURL or wget:

cURLwget

curl -fsSL https://raw.githubusercontent.com/percona/pmm/refs/heads/v3/get-pmm.sh | /bin/bash

wget -qO - https://raw.githubusercontent.com/percona/pmm/refs/heads/v3/get-pmm.sh | /bin/bash

After the installation is complete, log into PMM with the default admin:admin credentials.

What’s happening under the hood?

This script does the following:

Installs Docker if it is not installed on your system.
Stops and renames any currently running PMM Docker container from pmm-server to pmm-server-{timestamp}. This old pmm-server container is not a recoverable backup.
Pulls and runs the latest PMM Docker image.

Connect database¶

Once PMM is set up, choose the database or the application that you want it to monitor:

MySQL PostgreSQL MongoDB ProxySQL HAProxy

To connect a self-hosted MySQL database:

Create database account for PMM using the following command example. This creates a database user with name pmm, password <your_password>, and the necessary permissions:

CREATE USER 'pmm'@'127.0.0.1' IDENTIFIED BY '<your_password>' WITH MAX_USER_CONNECTIONS 10;
GRANT SELECT, PROCESS, REPLICATION CLIENT, RELOAD, BACKUP_ADMIN ON *.* TO 'pmm'@'127.0.0.1';

To optimize server-side resources, install PMM Client via Package Manager on the database node:
Debian-based Red Hat-based
Install the following with root permission:
1. Install the Percona Release Tool. If this is already, make sure to update it to the latest version:
  
  wget https://repo.percona.com/apt/percona-release_latest.generic_all.deb dpkg -i percona-release_latest.generic_all.deb
2. Enable the PMM client repository:
  
  percona-release enable pmm3-client release
3. Install the PMM Client package:
  
  apt update apt install -y pmm-client
Install the following with root permission:
1. Install percona-release tool. If this is already installed, update percona-release to the latest version.
  
  yum install -y https://repo.percona.com/yum/percona-release-latest.noarch.rpm
2. Enable the PMM client repository:
  
  percona-release enable pmm3-client release
3. Install the PMM Client package:
  
  yum install -y pmm-client

Register PMM Client:

pmm-admin config --server-insecure-tls --server-url=https://admin:admin@X.X.X.X:443

Add the MySQL database using Performance Schema:

pmm-admin add mysql --query-source=perfschema --username=pmm --password=<your_password>

Alternative database connection workflows

While the default instructions above focus on connecting a self-hosted MySQL database, PMM offers the flexibility to connect to various MySQL databases, including AWS RDS, Azure MySQL or Google Cloud MySQL.

The PMM Client installation also comes with options: in addition to the installation via Package Manager described above, you can also install it as a Docker container or as a binary package. Explore alternative PMM Client installation options for more information.

Additionally, if direct access to the database node isn’t available, opt to Add remote instance via User Interface instead.

To connect a PostgreSQL database:

Create a PMM-specific user for monitoring:

CREATE USER pmm WITH SUPERUSER ENCRYPTED PASSWORD '<your_password>';

Ensure that PMM can log in locally as this user to the PostgreSQL instance. To enable this, edit the pg_hba.conf file. If not already enabled by an existing rule, add:
```
local   all             pmm                                md5
# TYPE  DATABASE        USER        ADDRESS                METHOD
```
Set up the pg_stat_monitor database extension and configure your database server accordingly.

If you need to use the pg_stat_statements extension instead, see Adding a PostgreSQL database and the pg_stat_monitor online documentation for details about available parameters.
Set or change the value for shared_preload_library in your postgresql.conf file:
```
shared_preload_libraries = 'pg_stat_monitor'
```
Set up configuration values in your postgresql.conf file:
```
pg_stat_monitor.pgsm_query_max_len = 2048
```
In a psql session, run the following command to create the view where you can access the collected statistics. We recommend that you create the extension for the postgres database so that you can receive access to statistics from each database.
```
CREATE EXTENSION pg_stat_monitor;
```

For detailed instructions and advanced installation options, see Adding a PostgreSQL database.

To connect a MongoDB database:

Run the following command in mongo shell to create a role with the monitoring permissions:

db.createRole({
    "role":"explainRole",
    "privileges":[
        {
            "resource":{
                "db":"",
                "collection":""
            },
            "actions":[
                "collStats",
                "dbHash",
                "dbStats",
                "find",
                "listIndexes",
                "listCollections"
            ]
        }
    ],
    "roles":[]
})

Create a user and grant it the role created above:

db.getSiblingDB("admin").createUser({
    "user":"pmm",
    "pwd":"<your_password>",
    "roles":[
        {
            "role":"explainRole",
            "db":"admin"
        },
        {
            "role":"clusterMonitor",
            "db":"admin"
        },
        {
            "role":"read",
            "db":"local"
        }
    ]
})

Check database monitoring results¶

After installing PMM and connecting the database, go to the database’s Instance Summary dashboard. This shows essential information about your database performance and an overview of your environment.

For more information, see PMM Dashboards.
