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.

Account ID

The Account ID associated with the account to pull metrics from. For standalone installations, this is the account_id setting as configured in the "Graphite Listener" section of the /opt/circonus/etc/irondb.conf file.

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://www.circonus.com/ in the "User Profile" section.

Query Prefix

Prefix to be added to all queries sent to IRONdb.

• For standalone installations, this defaults to "graphite.".
• For hosted installations, this defaults to "reconnoiter.".

Usage

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

Normal Queries

For normal 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. The query prefix configured for the selected datasource is prepended to all queries against the IRONdb instance.

CAQL Queries

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

Histograms

Histograms currently require a special checkbox to be selected in order for the returned data to be processed correctly. Once selected, histogram data processing will be utilized for any returned data related to the specific metric.

Heatmaps

Using the histogram checkbox to process returned data allows for histograms to be displayed on the heatmap panel type.

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.
