Consumers and CLI commands can be monitored.

## Displaying CLI Monitoring Data

The consumers and CLI command monitoring data can be displayed toggling the Web/CLI dropdown.

## Enabling CLI Monitoring

Instrumentation of CLI commands and consumers needs to be manually triggered:

**PHP Application**

```php
// As of Blackfire PHP Probe 1.78.0
\BlackfireProbe::startTransaction('My CLI command');

// code

\BlackfireProbe::stopTransaction();
```

**Python Application**

```python
from blackfire import apm

# As of Blackfire Python Probe 1.6.1
apm.start_transaction()
apm.set_transaction_name('My CLI command')

# code

apm.stop_transaction()
```

CLI transactions should be manually named either before, during, or after the Instrumentation.
