Argus Versions Save

Noteworthy features:

• Serialize entire alert object (while writing to the queue) when scheduling so that alert evaluators need not get hit the DB to read alert definition
• /meta API performance improvements for dashboards and alerts
• CachedUserService implementation that persists user objects on the cache
• Enhancements to Discovery Service API
• ElasticSearch based schema service implementation. Can be configured using (service.binding.schema=com.salesforce.dva.argus.service.schema.ElasticSearchSchemaService)
• Changes/Enhancements to the following Transforms:
  1. GROUPBY: The scope is now set as the captured group. This helps in identifying different groups
  2. DOWNSAMPLE: Add capability to calculate percentiles when downsampling. E.g. DOWNSAMPLE(-1h:scope:metric:avg, #5m-p90#)
  3. PERCENTILE: Please see the wiki
  4. MOVING: Add sum capabilities to MOVING Transform to perform moving sum. E.g. MOVING(-1h:scope:metric:avg, #10m#, #sum#)
• Enable configuring multiple writeEndpoints with round robin and retry. E.g. (service.property.tsdb.endpoint.write=http://tsdbwrite1.mycompany.com:4477,http://tsdbwrite1.mycompany.com:4488,http://tsdbwrite2.mycompany.com:4477,http://tsdbwrite2.mycompany.com:4488)

Release Notes:

UI Features and Bug Fixes:

• Fullscreen mode: View a single chart in fullscreen
• Synchronize charts: Link multiple charts together to show the Y-axis line on each chart
• Chart options: New dialog for all chart options. can apply to all charts on page - which will reload the dashboard
• New table listing for metrics info (ag-table)
• Updates to Status Indicator to allow a decimal "." in the name and evaluate 0 values
• Update code-mirror plugin to prevent <style> tag causing error in markup field
• Other minor fixes to Annotations & chart rendering during brushing & zooming

Core/Platform Features and Bug Fixes:

• Add support for GOC Severity to notifications
• Add callback notifier for REST endpoint
• Shared dashboards are now accessible by users other than the owner
• User cache that holds top n user objects in memory
• OpenTSDB queries to use POST instead of GET
• Transform changes related to metric/scope name
• SchemaService format change, performance improvements and bug fixes (This is a non-backwards compatible change. Existing meta data created by schema service will no longer be useful. Please delete the old data and start the schema commit client to use the new meta data format.)

Release Notes:

• Firefox D3 Fix
• Shared Alerts UI and History/Audit support for shared alerts
• Better rendering of Annotation data on UI
• Notifications (cooldown, clear notifications, notifications sent) are now associated with each time series rather than an alert expression
• Distributed Scheduling Bug Fixes
• ALIAS by scope and metric E.g. ALIAS(-1h:argus.jvm:mem.heap.used{host=*}:avg, #newMetricName#, #literal#, #newScopeName#, #literal#)
• Perf metrics breakdown by user E.g. -1d:argus.custom:perf.ws.read.latency{user=,endpoint=}:avg
• Tags validation when submitting data to Argus
• Subtract time from parameterized date controls E.g. $start-2h$:$end-2h$:argus.core:commit.client.datapoint.writes:zimsum
• Add internal monitoring metrics:
  • No. of Notifications sent (can be broken down by status, type and host) E.g. -8h:argus.core:notifications.sent{type=,status=}:zimsum
  • No. of time series that violated a triggering condition E.g. -8h:argus.core:triggers.violated{host=*}:zimsum
• Other Bug Fixes and Improvements

2. SR Actionable flag for GOC Notifications.
