2. Restart Grafana.

Configuration

1. Create a new datasource and select IRONdb from the Type drop down.

HTTP

URL

• Standalone: If this datasource will access a standalone IRONdb cluster, then this is the URL where IRONdb can be accessed. Example: http://nodename:8112, or if TLS is in use, https://nodename:8443.

• Hosted: If this datasource will access data through Circonus, then the URL

• should be set as: https://api.circonus.com

IRONdb Details

1. Change the IRONdb configuration options at the bottom of the datasource configuration page.

IRONdb Type

• Standalone: An IRONdb cluster accessible directly, requires entry of Account ID.

• Hosted: An IRONdb instance hosted by Circonus, requires entry of API token.

• Depending on which of the above configurations you've chosen, you will either be presented with Account ID or API Token configuration options detailed below.

Account ID

The Account ID associated with the account to pull metrics from.

API Token

The API Token associated with the account to pull metrics from. This can be found on your API Tokens page after logging in at https://login.circonus.com/ in the "Integrations" -> "API Tokens" section.

• Note: Be sure to log into Circonus and change the Grafana App State to "allow" if that isn't the default for the provided API Token.

Usage

1. Create a new panel and set the datasource to name selected in the IRONdb datasource configuration.

Standard Queries

For standard Circonus metric queries, use the metric browser to navigate the metric hierarchy of your IRONdb instance or type queries manually using the Toggle Edit Mode menu item to the right.

CAQL Queries

CAQL queries must be entered manually by selecting the CAQL checkbox or switching manually to the editor mode.

Histograms

To visualize a histogram, you must search for the metric using find:histogram, for example:

find:histogram('foobar', 'and(hello:world)') | label('%cn')

Heatmaps

For this processed data to be displayed on the heatmap panel as the sample above, select Time Series Buckets as the Data Format to be used on the Heatmap panel.
