0.8.0-Preview Release Notes

Bosun

Upgrading

Since it has been over a year since the previous release it is possible not all breaking changes are accounted for, so you should test this out first and backup your redis/ledis data. Some known breaking changes:

• The elastic configuration is different, see System configuration :: ElasticConf for an example of what it should look like
• In order to support linking related incidents, a migration will run on the redis/ledis data on the first startup which will need to complete before Bosun starts running

Major Changes

• Notification Overhaul [PR #2135]. HTTP notifications are now much more flexible and can be used to interact with rest apis. See customizing notifications documentation. Please note that escalations on posts via notification chains are broken in this version, see issue 2304.
• New Azure Monitor datasource [PR #2283] which supports querying these metrics from Azure. There are also template function for Azure.
• Support connecting to multiple elastic clusters and of different versions of elasticsearch at runtime [300ebd8] [PR #2316].
• Incidents with the same alert keys are now linked to provide more context when handling alerts [PR #2323]. These links are displayed in the dashboard and incident view, and can also be used to include information (such as previous close messages and links to previous incidents) in templates using the new template property .PreviousIds and the .GetIncidentState template function.
• Rendered templates are no longer stored in redis/ledis indefinitely in order to control memory growth over time [PR #2167]. This can be set using MaxRenderedTemplateAge in the system configuration.
• Add Delayed Close so active alerts can be closed without waiting for the alert to go normal. 90cc3a9. Note: Needs Documentation

Expression Language Changes

• Add the generic SetVariant Type 95be5d9 so certain functions can take either a numberSet or a seriesSet such as addtags, filter and limit, and abs.
• Add aggr function to aggregate time series by group within a seriesSet. [PR #2294].
• Add OpenTSDB query functions with end duration parameter: shiftBand, overQuery, and bandQuery #2310.
• Add percentiles to OpenTSDB window func #2254
