# WHATPORT(8651)

## NAME

port 8651 — Ganglia gmetad XML port — gmetad's XML port — the aggregated view of every cluster it polls, on request.

Protocol: TCP

## DESCRIPTION

gmetad is the Ganglia component that polls gmond nodes and aggregates them into a grid. Its configuration file documents xml_port with "default: 8651", the port on which it answers requests for the full XML summary; the Ganglia web frontend reads from it. There is no IANA assignment for 8651 — the number is a project convention. Like gmond, gmetad has no authentication, only an optional trusted-hosts list.

## EXPOSURE

**Do not expose.** It returns the aggregated inventory of every cluster gmetad knows about. Restrict it to the monitoring host and the web frontend; there is no auth to fall back on.

## CHECK

```sh
nc TARGET 8651 | head -40
```
