Changelog and Release Notes

Version 5.2.1

New features

  • Elasticsearch: uberAgent now supports Elasticsearch 7


  • Browsers/IE add-on [I9]: the add-on now works in Internet Explorer’s Enhanced Protected Mode, too
  • GPU metrics [I12]: per-machine and per-process GPU compute usage now switches to an alternative algorithm if the original algorithm fails (observed with Nvidia Grid). This requires Windows 10 1709 or later.
  • GPU metrics: uberAgent now determines per process which GPU engine is used most heavily (requires Windows 10 1709)
  • Service: reduced verbosity of service interrogation debug messages


  • Citrix ADC [I8]: fixed error in Citrix ADC service group determination
  • Citrix ADC [I7]: fixed error in Citrix ADC gateway determination
  • Service [I6]: field names of KV sourcetypes are now normalized so that illegal characters are removed. This affects sourcetypes with dynamic field names, specifically uberAgent:System:PerformanceCounter. Allowed characters: [a-zA-Z0-9_]
  • Process startup [I14]: duplicate process GUIDs in the field ProcGUID if processes were started very quickly
  • Process startup [I15]: process starts missing in sourcetype uberAgent:Process:ProcessStartup if processes were started very quickly
  • Apache Kafka [I20]: fixed wrong timestamp format

Known issues

  • GPU: values for the fields ComputeUsagePercentAllEngines, ComputeUsagePercentEngine0 and so on, can be higher than 100 when using an Intel Iris GPU in combination with Windows Server 2016 1607
  • Citrix ADC: in very rare cases the content of the Virtual Server Performance field vServerName contains spaces in wrong places
  • Citrix XA/XD Machines: when running the Citrix VDA on a Citrix Delivery Controller, some per-machine information is missing
  • Browsers/IE add-on: metrics are not collected on page reload
  • Browsers/IE add-on: metrics are collected incompletely for the configured start page
  • IE browser performance monitoring does not work if IE is running as a Citrix XenApp published application. It does work from published desktops, however.
  • Boot duration: the metrics TotalBootTimeMs, MainPathBootTimeMs and PostBootTimeMs cannot be determined for every system boot
  • Browser web app performance: websites may modify the JavaScript performance variable. When that happens, uberAgent cannot determine the page load duration.
  • Update inventory: not all installed Windows updates may be reported due to API limitations

Release notes

  • Process GUIDs: changed the process GUID algorithm to drastically reduce the likelihood of collisions. ProcGUID field values generated with this version are different from the values generated by previous versions.
  • Splunk: removed the obsolete files eventtypes.conf and tags.conf from the dashboard app.
  • Sourcetype uberAgent:Process:ProcessDetail has new fields: ProcGpuEngineMostUsed and ProcGpuEngineMostUsedDisplayName
