# Wrap process monitoring

## Process Monitoring

<Tip>
  [Read our Process Monitoring documentation](/check-ins) for more information on how
  AppSignal Process Monitoring works.
</Tip>

By default, `appsignal-wrap` will not send any process monitor events. You can use the `--cron`
or `--heartbeat` command-line options to enable cron or heartbeat process monitors respectively.

The `appsignal-wrap` tool will use the name provided as the first argument as the process monitor identifier. For example, to report cron process monitor events with `backup-script` as the process monitor identifier:

<CodeGroup>
  ```sh Shell theme={null}
  appsignal-wrap backup-script --cron -- bash /var/app/backup.sh
  ```
</CodeGroup>

### Cron process monitors

When using `--cron` to send cron process monitors, `appsignal-wrap` will send a start cron process monitor event when the process starts, and a finish cron process monitor event if the process finishes successfully.

If the process exits with a failure exit status, `appsignal-wrap` will not send a finish cron process monitor event.

### Heartbeat process monitors

When using `--heartbeat` to send heartbeat process monitors, `appsignal-wrap` will send heartbeat process monitor events continuously during the lifetime of the process.

### Custom identifier

To send process monitor events to AppSignal with an identifier different from the name provided as the first argument, you can pass a different identifier as an argument to the `--cron` or `--heartbeat` command-line options. For example:

<CodeGroup>
  ```sh Shell theme={null}
  appsignal-wrap backup --cron daily-backup -- bash /var/app/backup.sh
  ```
</CodeGroup>

In the above example, `appsignal-wrap` will send cron process monitor events with `daily-backup` as the process monitor identifier, but will still use `backup` as the name to identify the process when reporting logs and errors.
