# pmdapostfix(1)

Postfix performance metrics domain agent (PMDA)

## NAME

**pmdapostfix** - Postfix performance metrics domain agent (PMDA)

## DESCRIPTION

**pmdapostfix** is a Performance Metrics Domain Agent (PMDA) which exports mail queue sizes as reported by [**qshape**(1)](/qshape/1.md), as well as aggregate statistics collected from mail.log.

## INSTALLATION

If you want access to the names and values for the Postfix performance metrics, do the following as root:

```
# cd $PCP_PMDAS_DIR/postfix
# ./Install
```

To uninstall, the following must be done as root:

```
# cd $PCP_PMDAS_DIR/postfix
# ./Remove
```

**pmdapostfix** is launched by [**pmcd**(1)](/pmcd/1.md) and should never be executed directly. The Install and Remove scripts notify [**pmcd**(1)](/pmcd/1.md) when the agent is installed or removed.
