# Show Device Performance

Shows performance metrics for one or more persistent memory modules.

```
ipmctl show [OPTIONS] -performance [METRICS] [TARGETS]
```

## **Metrics**

Shows output of a specific performance metric by supplying the metric name. See RETURN DATA for more information. One of:

* `MediaReads`: Number of 64 byte reads from media on the module since last AC cycle.
* `MediaWrites`: Number of 64 byte writes to media on the module since last AC cycle.
* `ReadRequests`: Number of DDRT read transactions the module has serviced since last AC cycle.
* `WriteRequests`: Number of DDRT write transactions the module has serviced since last AC cycle.
* `TotalMediaReads`: Number of 64 byte reads from media on the module over its lifetime.
* `TotalMediaWrites`: Number of 64 byte writes to media on the module over its lifetime.
* `TotalReadRequests`: Number of DDRT read transactions the module has serviced over its lifetime.
* `TotalWriteRequests`: Number of DDRT write transactions the module has serviced over its lifetime.

The default is to display all performance metrics.

## **Targets**

* `dimm (DimmIDs)`: Show the performance metrics of specific modules by supplying one or more comma-separated DimmIDs. The default is to display sensors for all manageable modules.

## **Examples**

Show all performance metrics for all modules in the server

```
$ ipmctl show -dimm -performance
```

Show the number of 64 byte reads since last AC cycle for all modules in the server

```
$ ipmctl show -dimm -performance MediaReads
```

# Agent Instructions: 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:

```
GET https://docs.pmem.io/ipmctl-user-guide/instrumentation/show-device-performance.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
