# 17.1.1. pmix_info

pmix_info — Display information about the PMIx installation

## 17.1.1.1. SYNOPSIS

`pmix_info [options]`

## 17.1.1.2. DESCRIPTION

`pmix_info` provides detailed information about the PMIx installation. It can be useful for at least three common scenarios:

1. Checking local configuration and seeing how PMIx was installed.

2. Submitting bug reports / help requests to the PMIx community (see Getting help).

3. Seeing a list of installed PMIx plugins and querying what MCA parameters they support.

## 17.1.1.3. OPTIONS

`pmix_info` accepts the following options:

- `-h` | `--help <arg0>`: Show help message. If the optional argument is not provided, then a generalized help message similar to the information provided here is returned. If an argument is provided, then a more detailed help message for that specific command line option is returned.

- `-v` | `--verbose`: Enable debug output.

- `-V` | `--version`: Print version and exit.

- `-a` | `--all`: Show all configuration options and MCA parameters.

- `--arch`: Show architecture on which PMIx was compiled.

- `-c` | `--config`: Show configuration options

- `--hostname`: Show the hostname on which PMIx was configured and built.

- `--internal`: Show internal MCA parameters (not meant to be modified by users).

- `--param <arg0>:<arg1>,<arg2>`: Show MCA parameters. The first parameter is the framework (or the keyword “all”); the second parameter is a comma-delimited list of specific component names (if only <arg0> is given, then all components will be reported).

- `--path <type>`: Show paths that PMIx was configured with. Accepts the following parameters: `prefix`, `bindir`, `libdir`, `incdir`, `pkglibdir`, `sysconfdir`.

- `--pretty-print`: When used in conjunction with other parameters, the output is displayed in “prettyprint” format (default)

- `--parsable`: When used in conjunction with other parameters, the output is displayed in a machine-parsable format

- `--parseable`: Synonym for `--parsable`

- `--show-failed`: Show the components that failed to load along with the reason why they failed

- `--selected-only`: Show only variables from selected components.

Returns 0 if successful, non-zero if an error is encountered
