Dear Diego:
Welcome to the APM Community. I hope you find this an invaluable resource and a friendly electronic neighborhood to visit.
Community Members: Can you add anything to this?
I see two questions in your post.
1) What metrics can I get from the PHP Agent?
That is covered in PHP Agent - CA Application Performance Management - 10.7 - CA Technologies Documentation
The PHP Agent provides the following features:
- Deep transaction trace visibility
- Automatic frontend detection and monitoring, including frontend URL group metrics
- Displays frontend URL group HTTP GET request metrics, which also display in transaction traces.
- MySQL metrics
Supported for these clients: MySQL (original), MySQLi (both object-oriented and procedural interfaces), and PHP Data Objects (PDO) interface - Oracle database metrics
Supported client: OCI8 - Custom instrumentation of the FrontendMarker, BlamePointTracer, and BackendMarker
The second question is how can I see more metrics with the PHP Agent?
Turning on DEBUG or VERBOSE in the Agent log (covered in Monitor PHP Agent Health - CA Application Performance Management - 10.7 - CA Technologies Documentation ) may give you clues as to what is happening.
