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
orwget
:curl -fsSL https://www.percona.com/get/pmm | /bin/bash
wget -qO - https://www.percona.com/get/pmm | /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
topmm-server-{timestamp}
. This oldpmm-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:
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:
Install the following with
root
permission:-
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
-
Install the PMM Client package:
apt update apt install -y pmm2-client
Install the following with
root
permission:-
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
-
Install the PMM Client package:
yum install -y pmm2-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 thepg_stat_monitor
online documentation for details about available parameters. -
Set or change the value for
shared_preload_library
in yourpostgresql.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 thepostgres
database so that you can receive access to statistics from each database.CREATE EXTENSION pg_stat_monitor;
-
