## Usage

### Write Configuration

Write configuration to `pyinsights.yml` like:

```yaml
version: '1.0'
log_group_name:
  - '/ecs/sample'
query_string: 'field @message | filter @message like /ERROR/'
duration: '30m'
limit: 10
```

I wrote examples, so see [examples folder](https://github.com/homoluctus/pyinsights/tree/master/examples).

### Execute command

```bash
pyinsights -c pyinsights.yml -p aws_profile -r region
```

## Configuration

### version

Specify CloudWatch Logs Insights query commands.
Please see [CloudWatch Logs Insights Query Syntax](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/CWL_QuerySyntax.html).

:warning: If query_string type is array, Unix-style pipe `|` is not required. Execute in order from the top.

ex)

```yml
query_string:

```

Equal to

```yml

```

#### type: object

Specify `start_time` and `end_time`.
The format must be `YYYY-MM-DD HH:MM:SS`.

ex)

```yml

```
