Network¶
Ports¶
This is a list of ports used by the various components of PMM.
For PMM to work correctly, your system’s firewall should allow TCP traffic on these ports (UDP is not needed).
Ports to expose:
| PMM component | TCP port | Direction | Description |
|---|---|---|---|
| PMM Server | 80 | both | HTTP server, used for gRPC over HTTP and web interface (insecure, use with caution). |
| PMM Server | 443 | both | HTTPS server, used for gRPC over HTTPS and web interface (secure, use of SSL certificates is highly encouraged). |
Other ports:
| PMM component | TCP port | Direction | Description |
|---|---|---|---|
| PMM Server | 7771 | both | gRPC, used for communication between pmm-agent, pmm-admin. |
| PMM Server | 7772 | out | HTTP1 server, used for older links like logs.zip. |
| PMM Server | 7773 | out | Debugging. |
pmm-agent |
7777 | out | Default pmm-agent listen port. |
vm-agent |
8428 | both | VictoriaMetrics port. |
pmm-agent |
42000 - 51999 | in | Default range for pmm-agent connected agents. |
Important
Depending on your architecture other ports may also need to be exposed.
- For pmm-agent, the default listen port is 7777.
- The default port range for pmm-agent is large by default to accomodate any architecture size but it can be modified using the --ports-min and --ports-max flags, or modifying the configuration file. In network constraint environments, the range can be reduced to a minimum by allocating at least one port per agent monitored. Learn more about available settings for pmm-agent in Percona PMM-Agent documentation.
Network configuration for locked-down environments¶
For computers in a locked-down corporate environment without direct access to the Internet, make sure to enable access to Percona Platform services following the instructions in the Percona Platform documentation.
