Msgstat
----------
Msgstat provides a CLI tool which analyses status-go log files and generates corresponding aggregated data
related to messages delivery over whisper (either rpc or p2p) protocols.

## Usage

Msgstat spits out structures that provide commulation of all related facts about a given message based on desired output format supported.

*It by defaults expects processed data to be delivered either through pipes through `stdin` or through the use of the `file` flag.*

- Processing log lines through stdin

```bash
> cat ./logs/status-im/status-go/11.21.2017.log | msgstat
```

- Processing log lines through stdin with `yaml` output format

```bash
> cat ./logs/status-im/status-go/11.21.2017.log | msgstat -format=yaml
```

- Processing log lines from a file

```bash
> msgstat -file=./logs/status-im/status-go/11.21.2017.log
```

All processed data is written through `stdout`, except when the use of the `-out` flag is used to point to a output file to contain
created data.

### Flags

#### `-file=./status-log`

This flag is used to indicate that file should be used to retrieve all log lines to be processed.

#### `-out=./processed-log.json`

This flag is used to indicate that all processed data should be stored into provided path.

#### `-format=json|yaml|toml`

This flag is used to dictate the encoding format which should be used for aggregated data.


### Log Input Format

Msgstat expects that all log contain log lines separated by new lines, and targets log lines such has below:

```

```

Msgstat will extract any log lines with matching `Message Delivery Notification` header, extracting the `state` field and it's value which contains base64 encoding delivery data.


### Output Format
