# pmdasmart(1)

S.M.A.R.T Data PMDA

## NAME

**pmdasmart** - S.M.A.R.T Data PMDA

## SYNOPSIS

**$PCP\_PMDAS\_DIR/smart/pmdasmart** \[**-D** *debug*\]

## DESCRIPTION

**pmdasmart** is a Performance Metrics Domain Agent (PMDA) which exports metric values for Device Mapper on the local system.

This PMDA collects its data through the [**smartctl**(8)](/smartctl/8.md) utility and requires that the program is installed in order to function.

Further details on smartctl and smartmontools can be found at **https://smartmontools.org**.

## INSTALLATION

Install the SMART PMDA by using the Install script as root:

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

To uninstall, do the following as root:

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

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

## FILES

- **$PCP\_PMDAS\_DIR/smart/help**

  default help text file for the smart metrics

- **$PCP\_PMDAS\_DIR/smart/Install**

  installation script for the **pmdasmart** agent

- **$PCP\_PMDAS\_DIR/smart/Remove**

  undo installation script for the **pmdasmart** agent

- **$PCP\_LOG\_DIR/pmcd/smart.log**

  default log file for error messages from **pmdasmart**

## PCP ENVIRONMENT

Environment variables with the prefix **PCP\_** are used to parameterize the file and directory names used by **PCP**. On each installation, the file **/etc/pcp.conf** contains the local values for these variables. The **$PCP\_CONF** variable may be used to specify an alternative configuration file, as described in [*pcp.conf*(5)](/pcp.conf/5.md).

## DEBUGGING OPTIONS

The **-D** or **--debug** option enables the output of additional diagnostics on *stderr* to help triage problems, although the information is sometimes cryptic and primarily intended to provide guidance for developers rather than for end-users. *debug* is a comma separated list of debugging options; use [**pmdbg**(1)](/pmdbg/1.md) with the **-l** option to obtain a list of the available debugging options and their meaning.
