# Performance monitoring

You can use logging to monitor and review system performance. Pentaho provides you with several methods to monitor system performance. PDI logging offers you summarized information on transformations and jobs, while Pentaho logging provides detailed information about exceptions, errors, and debugging. You can maintain Pentaho logging through various tools. You can also monitor performance using the Pentaho Operations Mart. Third-party logging such as SNMP is also supported.

For instructions for using logging to monitor system performance, see the following topics:

* [PDI logging](/pdia-admin/9.3-administer/optimize-the-pentaho-system/monitoring-system-performance/pdi-logging.md)
* [Maintain logging](/pdia-admin/9.3-administer/optimize-the-pentaho-system/monitoring-system-performance/maintain-logging.md)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdia-admin/9.3-administer/optimize-the-pentaho-system/monitoring-system-performance.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
