## Meta Queries Plugin for Grafana:
Meta Queries plugin is built as a data source plugin and can be used in conjunction with other data source to show computed metrics like Moving Average, Time Shift.
  
## Installation
Need to clone this repo into your grafana plugins directory (default /var/lib/grafana/plugins if your installing grafana with package).
Restart grafana-server and the plugin should be automatically detected and used.

```
git clone git@github.com:GoshPosh/grafana-meta-queries.git
sudo service grafana-server restart
```

## Usage
1. Create a new datasource and select `MetaQueries` as the desired type.

2. And new panel and set the `MetaQueries` as the data source.

3. On the top right corner, Click on Add query. Select the desired data source and specify the query as desired (add a few more).

4. Add a `MetaQueries` query, and preform the wanted manipulation (examples listed below)
The Reference to the queries should be made both by query and it's metrics names.
For example, from query `A` we'd like to work against metric calls `Test`, the refferer should be A['test'].

## Examples
#### Arithmetic
Lets you perform arithmetic operations on one or more existing queries.
