Log monitoring

  • Host id information is missing for docker container logs (APM-181651)


  • Odd UI behavior when setting the value of the global setting for Infra memory usage. (APM-180907)
  • We have wrong label for ec2 machines. It was AWS Elastic Container Service instead of AWS Elastic Compute Service. (APM-182008)
  • Firefox - tooltips on infographic not showing up (APM-182009)
  • Old network overview - nic/pgi list is not filtered by management zone (APM-182335)
  • In special case, when two plugins creates the same group of chart we may create a single chart with series from two different plugins. (APM-182657)
  • On Network overview page, appears a filter even though we have no monitored networks (APM-182814)
  • Deployment status filter: inconsistency of operating system name 'linux' vs. 'Linux' (upper / lower case) (APM-183150)
  • Technology tiles - affected instances not displayed correctly (APM-183968)
  • zLinux agent install command line contains parameter that is not valid for this platform (APM-184354)

  • Oracle DB Insights: Configurations were not visible when configuration entries with the same fields were added (APM-183675)
  • USQL: Selecting useraction.navigationStart and grouping by useraction.navigationStart leads to empty results (APM-184069)
  • Specific USQL query returns the fully qualified Java class in the user-visible response (APM-182883)
  • Customer is unable to change the sensitivity for Anomaly detection on service RentalAgreement. Possible UI Bug. (APM-182527)
  • Not being alerted on problems (APM-182316)
  • Fixed notification bug that if a problem was already notified to an integration and a new event correlated into the problem afterwards which is part of a maintenance window which is configured to suppress problem creation/alerting, no resolved notification would be sent out and problems would forever stay open in stateful integrations (e.g. PagerDuty, OpsGenie) (APM-182919)
  • AWS initial connection test is now checking all regions in partition (APM-182129)
  • Users which have a very large number of Management Zones assigned may have issues sharing dashboards (APM-172801)
  • Dashboard sharing: Sharing cannot be disabled if sharing token cannot be created (APM-182130)
  • Single host view response time regression (APM-182957)
  • ActiveGates before sprint 154 may cause performance impact on cluster nodes if the cluster has a very large number of API tokens. (APM-183401)
  • Previously available token permissions are no longer possible to assing in the token REST API. (APM-183782)
  • Default behavior of the VMware monitoring flag of old Environment ActiveGates corrected: AGs < Sprint 100 now have the flag "on" as default AGs >= Sprint 100 act as configured by the customer (APM-181908)
  • Improved Agent HEAD request handling in ActiveGates: Previously the ActiveGate defaulted to a valid 204 if an Agent sent a HEAD request due to the missing server information on the Http request. ActiveGates now check if at least one server is reachable to return a valid 204. This improves re-connection of agents if the ActiveGate has network connectivity problems (as in this case where the ActiveGate had a problem with certificate resolution due to missing certificate store) (APM-182700)
  • The introduction of a quality of service control mechanism in release 170 introduced an unexpected thread pool bottleneck that temporarily blocked the Cluster REST API endpoints under very heavy load scenarios for one particular customer. Data ingest from agents was not affected and therefore no data was lost during that timeframe. The original default values have been restored. (APM-183527)
  • A new PHP Agent flag was introduced which can lead to an agent crash if sent to PHP agents with a version older than Sprint 171. The cluster now handles this case and skips the flag for older agents (APM-184726)
  • Can not save User-Agent value while configuring HTTP monitor (APM-181229)
  • Fixed problems with selecting sections of infographic on process overview page. (APM-184910)
  • Improvements for value formatting in network charts. Values may be slightly different from real values. (APM-183891)
  • AWS ASGs that were defined empty and didn't have any EC2s assigned during selected timeframe were removed from list of ASGs. (APM-184290)
  • [Deploy Dynatrace] Windows link directs to Linux installer (APM-184544)
  • Improvement when selecting a build unit based on the associated version. Now we check all installer versions in build unit matching by type, not only the first matching installer version, as was done previously (APM-184610)
  • AWS Custom Alerts - Elastic Load Balancer should be called Classic Load Balancer (APM-184999)
  • Limits on Docker overview page for displaying more data and not limiting view too early. (APM-185506)
  • Problem notifications tiles are too short (APM-186314)
  • Oracle DB tablespaces monitoring was showing summed metrics instead of current information about space used by database. The fix has changed the way of consuming metrics responsible for tablespaces usage information and allowed customer to using aggregations. (APM-184503)
  • USQL: Selecting useraction.navigationStart and grouping by useraction.navigationStart leads to empty results (APM-184069)
  • Fixed changing of log perspective on sources selection (APM-175844)


  • Fixed that users that only had the rights to Access the environment on a Management zone could not pin USQL tiles to a dashboard. (APM-186103)
  • Fixed an issue where Internet Explorer users experienced an error when clicking in the suggestion list. (APM-185605)
