bosun v0.8.0 Release NotesRelease Date: 2018-10-10 // about 1 year ago
🚀 0.8.0-Preview Release Notes
🚀 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
- 📚 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
- 🔧 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

Previous changes from v0.6.0
🚀 0.6.0-beta Release Notes
🔧 The main goal of Bosun 0.6.0 was to smooth out the alert creation and editing workflow. Previously, users would have to copy the configuration from Bosun's UI, get it to the server, and then restart the process. Now users can edit the config directly from Bosun's UI, and the changes will be loaded without restarting the bosun process. Since the rules can now be edited via Bosun's UI, authorization via LDAP and SSL support has been added as well.
- 🔧 Bosun's configuration file has been split into two files:
- 💻 Bosun's RuleConf can now be edited via Bosun's UI. The changes can then be reloaded without restarting the Bosun process.
- 🔧 Bosun now has support for authorization via LDAP and Tokens that can be configured via the auth section of the system configuration.
- Bosun's dashboard loads much faster than 0.5.0 due to schema change
- 📚 Many errors can now be handled in templates making them more robust against runtime errors, and template documentation has been improved.
- 🔧 Since the configuration file has been split, you will need to move some of what used be in the config into system configuration.
- ⬆️ On the first execution, a database schema migration will take place that can take several minutes. During this time bosun will not be available. It is recommended to back up Bosun's database before the upgrade.
- 🆕 New Expression Functions:
- 🆕 New Template Functions / Variables:
- 💻 Comments are now allowed in the Expression Page in Bosun's UI.
- Bosun's navbar now shows if quiet mode is enabled.
- Notes can now be added to incidents.
- 👌 Improved Bosun's incident view.
- 👌 Improved Bosun's graph page to be more keyboard friendly: better order of fields with the TAB key and shift-enter within text fields will execute.
- ⚡️ Updated Influx library to be compatible with current versions.
- 🐎 Optimized elastic query performance by not fetching indices and fix bug caused by indices not being part of the cache key #1931.
- 🛠 Fixed issue in scheduler where adjacent runs would be given the same to represent "now" #2029.
- 👍 Allow the empty tagset to be a dependency for alerts that have tags #2027.
- 💻 Adjustments to Bosun's UI to make it more vertically compact.
- 🛠 Fixed HTTP template funcs to have a shorter timeout so they don't block template rendering for too long when they timeout.
- 👍 Allow empty tagsets in silence silence: allow empty tag sets #1860.
Expected Changes Between Beta and 0.6.0 final:
- 🔌 Tooling outside of the Bosun process doesn't have auth support (except for the Grafana Plugin). The following will have auth support before final: scollector, (cli tools: annotate, silence), tsdbrelay, BosunReporter.NET, and Opserver.
- 👌 Support for multiple Elastic backends in a single instance may be added. If this happens the syntax for the system configuration (toml file) of elastic might change.
