# runai mpi logs

view logs of a mpi training job

```
runai mpi logs [WORKLOAD_NAME] [flags]
```

## Examples

```
# Get logs for a mpi training
runai training mpi logs mpi-01

# Get logs for a specific pod in a mpi training
runai training mpi logs mpi-01 --pod=mpi-01-worker-0

# Get logs for a specific container in a mpi training
runai training mpi logs mpi-01 --container=mpi-worker

# Get the last 100 lines of logs
runai training mpi logs mpi-01 --tail=100

# Get logs with timestamps
runai training mpi logs mpi-01 --timestamps

# Follow the logs
runai training mpi logs mpi-01 --follow

# Get logs for the previous instance of the mpi training
runai training mpi logs mpi-01 --previous

# Limit the logs to 1024 bytes
runai training mpi logs mpi-01 --limit-bytes=1024

# Get logs since the last 5 minutes
runai training mpi logs mpi-01 --since=300s

# Get logs since a specific timestamp
runai training mpi logs mpi-01 --since-time=2023-05-30T10:00:00Z

# Wait up to 30 seconds for mpi training to be ready for logs
runai training mpi logs mpi-01 --wait-timeout=30s
```

## Options

```
  -c, --container string        Container name for log extraction
  -f, --follow                  Follow log output

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://run-ai-docs.nvidia.com/self-hosted/2.20/reference/cli/runai/runai_mpi_logs.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
