Installation

The easiest way to install this plugin is to clone or unzip this repository on the grafana plugins folder. For example:

cd /var/lib/grafana/plugins
git clone https://github.com/pueteam/datasource-plugin-solr

Then restart grafana to reload the plugins folder.

Configuration

1. Add a new datasource and choose "Solr" as the type.

2. Fill in the "Url" and other server parameters. If you run Solr in a kerberized cluster, you'll need LDAP authentication enabled, and provide the credentials here.

3. Optionally, add the collection to use. This is required if you plan to use templates.

4. Click "Test Connection" to verify that you entered the information correctly.

5. Cick "Save".

Queries

First, select the query type. You can choose between standard and group. The standard query is the default.

• Standard Queries: The standard queries will execute regular queries against Solr. You'll need to fill the Collection, the Timestamp field, the Fields list (space or comma separated) and the Query in the Solr format *:*.

• Group Queries: The group type allows you to group results by Group By Field parameter. You'll also need to fill the Group Value Field and this parameter should be numeric. You can also limit the Max Group Rows results.

Template Support

This plugin supports Templates/Variables to be used, for example, in the Query parameter. You'll need to specify the Collection parameter in the Datasource parameters.

CR:$CR AND city:$city

Autocompletion Support

This plugin supports auto completion for the Query Parameters.

Annotation Support

This plugin also supports Annotations. You'll need to provide:

• Collection
• Query
• Tags
• Title
• Text
• Time

Development

To compile, run the following commands:

npm install
grunt

To install in your Grafana server locally, either point Grafana at the repository directory by editing grafana.ini to contain:

[plugin.solr]
path = /path/to/some/directory/datasource-plugin-solr

Or symlink the repository directory into the Grafana server's plugin directory:

cd /path/to/grafana/data/plugins
ln -s /path/to/some/directory/datasource-plugin-solr .

Then restart the Grafana server.
