Features

• DynaTrace Topology Integration:
  • Create the topology in StackState from Dynatrace smartscape topology 
• Added support for integrations to send events that can be linked to the topology in StackState using Event Context 
• ServiceNow Integration:
  • ServiceNow Change Request are monitored in StackState with all updates to the Change Request state reflected as external events in StackState, such that potential failures can be related to a change in ServiceNow 
  • Added support for filtering ServiceNow CI's using a custom sysparm_query 
  • Support for custom cmdb_ci field that acts as the Configuration Item identifier 
• Integrations:
  • Added local persistent state that can be used by integrations to persist a JSON object per check instance to disk 
  • Support dynamic identifier building from check configuration using identifier_mappings 
• Kubernetes Integration:
  • Map Kubernetes events to Kubernetes components in StackState as events 
  • Add extra topology component for ExternalName K8s services, that can merge with the actual service in use

Improvements

• Integrations:
  • Kubernetes, Kubelet, Kubernetes State and OpenMetrics integrations are monitored by StackState 
  • Check API supports auto snapshots when setting with_snapshots to True in the TopologyInstance 
  • Sanitize events and topology data in the base check, encoding Unicode to string, before propagating data upstream 
  • Added functionality to the Identifiers utility to provide lower-cased identifiers for all StackState-related identifiers
• Trace agent:
  • Interpret Traefik traces so that the Traefik component is not the parent of a service-instance 

Bugfix

• VSphere Integration:
  • Reconnect on an authentication session timeout 
  • Metric collection for components in Vsphere is now limited to the configured config.vpxd.stats.maxQueryMetrics value 
• Integrations:
  • Fixed python2 UTF-8 string encoding in data produced by all integrations 
  • Fixed spurious updates of Agent Integrations components in StackState 
  • Fixed a memory leak in the integrations caused by yaml.safe_load when loading large objects 
• Nagios Integration:
  • Fixes service name not visible in check details 
• Remove reference of datadog in the log for core ntp check 
• Network Tracer:
  • Fix loopback address detection
