Feature updates

Application Observability | OneAgent

Added support for Red Hat Enterprise Linux 10.0

You can now install OneAgent on Red Hat Enterprise Linux 10.0.

Digital Experience | Session Replay

Session Replay for Mobile Apps is available for all customers

Session Replay for mobile apps lets you watch how users interact with your native mobile apps in a video-like playback that captures taps, gestures, and navigation flows. It helps practitioners resolve customer complaints, reproduce issues, analyze user behavior, and improve overall mobile experience with real-world context and no guesswork.

For more information, see Configure Session Replay for iOS and Configure Session Replay for Android.

Application Observability | Live Debugger

Live Debugger now available across all host monitoring modes

Live Debugger can now be activated in the lightweight Discovery and Infrastructure monitoring modes, expanding its functionality beyond full-stack monitoring. This allows you to troubleshoot issues in real time for your 2nd and 3rd tier applications, enabling faster resolution without the need to switch to full-stack mode.

Application Observability | Log Analytics

OneAgent log module can ignore timestamps in lines starting with whitespace characters

You can configure the OneAgent log module to ignore timestamps in lines starting with white characters.

To configure it

  1. Go to Settings > Collect and capture > Log monitoring > Timestamp / Splitting patterns.
  2. Create or edit your rule to turn on Skip indented lines.

Digital Experience | RUM Web

Send Space as a standalone user interaction event and ignore pointer events with pointerId of -1

Rum Web Agent will now also send a user interaction event when a standalone Space key is pressed. Trusted synthetic click events that have pointerId of -1 are now ignored. This can happen if you tab on an element and press Space on it to activate it, for example, on a native button. This would result is sending duplicate events such as click and keypress.

Infrastructure Observability | Hosts

Host metrics no longer reported in Discovery mode: host total swap, disk used percentage, and process total I/O bytes used

The following metrics are no longer reported in Discovery mode:

  • dt.host.memory.swap.total (builtin:host.mem.swap.total)
  • dt.host.disk.used.percent (builtin:host.disk.usedPct)
  • dt.process.io.bytes_total (builtin:tech.generic.io.bytesTotal)

Platform | OneAgent

  • Latch suspension time
  • Number of SELECTS
  • Number of INSERTS
  • Number of UPDATES
  • Number of DELETES
