Changelog

0.9.28

Adjusted frequency of autocomplete requests to improve performance.

0.9.27

Added anonymized usage statistics so we can prioritize development time based on feature usage.

0.9.26

A new variable query type is available: "Last Metric Value" which will support text metric values. This allows you to show text metric values in text panel widgets.

0.9.25

Now when histogram streams are found by Graphite-style searches, their data is displayed, even on line graphs which aren't set to heatmap rendering.

0.9.24

Eliminates the need for a call to the graphite_translate IRONdb extension in the alerting backend for Graphite style queries.
Ensures that all CAQL queries issued via the API /caql endpoint by the alerting backend contain a #min_period prefix if a min_period value has been defined for the Grafana query object.
Adds handling for the possibility of null or non-numeric data values being returned to the alerting backend by its calls to the API /caql endpoint.

0.9.23

Fix base64 encoding of variable values when used inside other variable queries.

0.9.22

When substituting CAQL queries inside other CAQL queries, remove directives from sub-queries.

0.9.21

Now when CAQL warnings are returned, they're thrown as UI errors by default; there's a datasource configuration setting to hide these errors.

0.9.20

Fix Graphite-style autocomplete results when an empty leaf is returned.

0.9.19

Updates dependencies to latest versions.
Fixed a bug where the API client used by the datasource could retry on response errors multiple times, potentially causing a large number of API requests to be generated.

0.9.16

Fixed a bug where values of zero weren't being plotted from CAQL data.

0.9.15

re-synchronizing package metadata

0.9.11

The alerting backend will now process queries in parallel.
Update plugin.json to use newer grafanaDependency setting.

0.9.10

Update release build actions.

0.9.9

0.9.8

Implements support for graphite type queries in the alerting backend.

0.9.7

0.9.6

Corrects an issue caused by grafana not including the URL for the data source in the configuration JSON.
Improves the logging performed by the IRONdb alerting back end. Errors parsing JSON passed to the back end will now log better descriptions of the problem along with the erroneous JSON.

0.9.5

Fixes the alerting backend so that the min_period value for generated CAQL queries is correctly using the setting or default from the UI.

0.9.4

Fix labels for untagged metrics
