Shell Completions
-----------------

`grofer` includes a subcommand to generate shell completion scripts to get autocompletion for subcommands and flags
Usage
=====

### Bash
```
grofer is a system and resource monitor written in golang.
To get completions for current session only,
While using a TUI based command, press ? to get information about key bindings (if any) for that command.
```sh
source <(grofer completion bash)
```
Usage:
grofer [flags]
grofer [command]
To load completions for each session, the generated script must be moved to the completions directory. Take a look at the third question [here](https://github.com/scop/bash-completion/blob/master/README.md#faq) to find out the right place to put the script
Available Commands:
about about is a command that gives information about the project in a cute way
completion Generate completion script
container container command is used to get information related to docker containers
export Used to export profiled data.
help Help about any command
proc proc command is used to get per-process information
### Zsh
Flags:
--config string config file (default is $HOME/.grofer.yaml)
-c, --cpuinfo Info about the CPU Load over all CPUs
-h, --help help for grofer
-r, --refresh uint Overall stats UI refreshes rate in milliseconds greater than 1000 (default 1000)
If shell completion is not already enabled in your environment you will need to enable it. You can execute the following once:
Use "grofer [command] --help" for more information about a command.
```sh
echo "autoload -U compinit; compinit" >> ~/.zshrc
```

To load completions for each session, the generated script must be placed in a directory in your [fpath](http://zsh.sourceforge.net/Doc/Release/Functions.html). For a quick-and-dirty solution, run once:
Display Overall Metrics
-----------------------

```sh
grofer completion zsh > "${fpath[1]}/_grofer"
grofer [FLAGS]
```

You will need to start a new shell for this setup to take effect.
The command displays the default root page which provides verall CPU, Memory, Network and Disk Metrics.

### Fish
Optional flags:

To get completions for current session only,
- `-c | --cpuinfo`: Enabling this flag provides detailed information about CPU loads.

- `-h | --help`: Provides help information about grofer.

- `-r | --refresh UINT`: Sets the UI refresh rate in milliseconds. The number (UINT) provided must be greater than 1000

Display Process Metrics
-----------------------

```sh
grofer completion fish | source
grofer proc [FLAGS]
```

To load completions for each session, the generated script must be moved to the completions directory
This command displays a table with information about all running processes. Additionally, it can be used to kill a running process too. Key-bindings for navigation and available process actions can be found by pressing `?` in the UI.

Optional flags:

- `-h | --help`: Provides help details for `grofer proc`.

- `-p | --pid INT32`: Provides in depth metrics about process identified by given PID.

- `-r | --refresh UINT`: Sets the UI refresh rate in milliseconds. Much like the root command, this value must be greater than 1000.

Display Container Metrics
-------------------------

```sh
grofer completion fish > ~/.config/fish/completions/grofer.fish
grofer container [FLAGS]
```

Usage
-----
This command displays information about all existing containers. Key-bindings for navigation and available container actions can be found by pressing `?` in the UI.

Optional flags:

- `-h | --help`: Provides help details for `grofer container`.

- `-c | --container-id STRING`: Provides in depth metrics about the container identified by given ID.

- `-r | --refresh UINT`: Sets the UI refresh rate in milliseconds. Much like the root command, this value must be greater than 1000.

Export Metrics
--------------

```sh
grofer export [FLAGS]
```
grofer is a system and resource monitor written in golang.

While using a TUI based command, press ? to get information about key bindings (if any) for that command.
This command exports collected information to a specifc file format.

Usage:
grofer [flags]
grofer [command]
Optional flags:

Available Commands:
about about is a command that gives information about the project in a cute way
completion Generate completion script
export Used to export profiled data.
help Help about any command
proc proc command is used to get per-process information
- `-h | --help`: Provides help details for `grofer export`.

Flags:
--config string config file (default is $HOME/.grofer.yaml)
-c, --cpuinfo Info about the CPU Load over all CPUs
-h, --help help for grofer
-r, --refresh uint Overall stats UI refreshes rate in milliseconds greater than 1000 (default 1000)
-t, --toggle Help message for toggle
- `-i | --iter UINT32`: Set the number of iterations to fetch data.

Use "grofer [command] --help" for more information about a command.
- `-p | --pid INT32`: Specify the PID of the process to profile. If not set, all processes are are measured.

```
- `-t | --type STRING`: Specify the export file format. Defaults to LJSON.

---
- `-f | --filename STRING`: Specify the file to store the exported data in. Defaults to `grofer_profile`.

Examples
--------
- `-r | --refresh UINT`: Specify frequency of data fetch in milliseconds. default value taken as 1000.

`grofer [-r refreshRate] [-c]`
------------------------------
Examples
========

This gives overall utilization stats refreshed every `refreshRate` milliseconds. Default and minimum value of the refresh rate is `1000 ms`.

This provides overall container metrics.

This allows exporting of profiled data either of system usage or data particular to that of a process. Data format is JSON by default, but XML support exists too!

The flags are explained as follows:
---

- `-i, --iter`: Number of iterations to profile for.
```
grofer container -c CID
```

- `-f, --filename`: Name of output file (exported data).
This provides per container metrics.

- `-r, --refresh`: Refresh rate, time interval between iterations (in milliseconds).

- JSON: Specifically, LJSON, where each line consists of one JSON object which contain nested fields and values.
- CPU and Per CPU utilization %

- `-p, --pid`: Specify PID of process to profile.

- Volume Mounts

- Attached Networks

- Block and Network I/O
