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
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.


Depending on your architecture other ports may also need to be exposed. - For pmm-agent, the default listen port is 7777. - The default range for agents ports can be changed with the flag --ports-min and --ports-max, or in the configuration file.
