pt-mongodb-summary
==================
**pt-mongodb-summary** collects information about a MongoDB cluster.

Usage
-----
pt-mongodb-summary [options] [host:[port]]

Default host:port is `localhost:27017`.
For better results, host must be a **mongos** server.

Binaries
--------
Please check the `releases <https://github.com/percona/toolkit-go/releases>`_ tab to download the binaries.

Parameters
^^^^^^^^^
|Short|Long|Default|Description|
|-----|----|-------|-----------|
|-a|--auth-db|admin|database used to establish credentials and privileges with a MongoDB server|
|-f|--output-format|report output format|Valid values are text, json. Default: text|
|-f|--output-format|text|output format: text, json. Default: text|
|-p|--password|empty|password to use when connecting if DB auth is enabled|
|-u|--user|empty|user name to use when connecting if DB auth is enabled|


``-p`` is an optional parameter. If it is used it shouldn't have a blank between the parameter and its value: `-p<password>`
It can be also used as `-p` without specifying a password; in that case, the program will ask the password to avoid using a password in the command line.

This program needs to run some commands like ``getShardMap`` and to be able to run those commands
it needs to run under a user with the ``clusterAdmin`` or ``root`` built-in roles.
