View Device Metrics for Prisma Browser
The ADEM Browser Extension collects endpoint hardware specifications and browser
resource metrics, displayed as device attributes and dynamic health trend charts.

When the ADEM Browser extension is active on a user's browser, it collects two categories
of metrics: static hardware attributes gathered once at session start and dynamic
browser resource metrics gathered every 30 seconds. Static attributes appear in the
Device Details view on the User
Details page. Dynamic metrics appear as trend charts in the
Device Health Metrics section under Synthetic
Trends.
Device Details
The Device Details view displays six hardware specification
cards in a single row. The previous Hardware card is
replaced by separate CPU, Memory, and
Disk cards. Browser Type and Browser Version are combined
into a single Browser card.
| Card / Field | Description |
|---|
| DEVICE — Device Name | Hostname of the monitored endpoint. |
| OS — OS Version | Full operating system version string including the
build number. For example, macOS 15.2 (24C101) or
Windows 11 23H2 (22631.4890). |
| CPU — CPU Model | Processor model name as reported by the operating
system. For example, Apple M2 or Intel Core
i5-1235U. If unavailable, displays as
Unknown. |
| CPU — CPU Cores | Number of logical CPU cores available to the
operating system, including hyperthreading virtual cores. Virtual
machines report the core count allocated to the VM. |
| MEMORY — Total RAM | Total physical memory installed on the device,
rounded to the nearest whole GB. |
| DISK — Hard Disk Total | Total capacity of the primary OS volume (normally
C:\ on Windows, / on macOS). External drives,
network drives, and secondary volumes are excluded. |
| DISK — Hard Disk Free | Available space on the primary OS volume. On macOS
with APFS, purgeable space counts as free. |
| BROWSER | Browser type and version. |
Static metrics are collected once at session start and updated when a change is
detected on the device.
Device Health Metrics
The Device Health Metrics section of Synthetic
Trends includes four new browser resource trend charts alongside the
existing Memory, CPU, Battery, Disk Usage, and Disk Queue Length charts. Select a
metric's check box to show or hide its trend chart.
| Metric | Description |
|---|
| Tabs Open | Count of all open browser tabs across all windows of
the current browser instance. |
| Browser Windows | Count of distinct browser windows open, including
incognito and private windows. Each browser application (for
example, Prisma Browser and Chrome running simultaneously) is
counted separately. |
| Avg Memory per Tab | Total tab renderer process memory divided by the
number of open tabs. Extension processes, the GPU process, and
utility processes are excluded from the calculation. If all tabs are
closed, the value is 0. Discarded tabs report approximately 0 MB and
reduce the average. |
| Total Browser Memory | Sum of all memory consumed by the browser
application, including tab renderers, extension processes, the GPU
process, utility workers, and the browser main process. This is
browser-specific memory, not system-wide memory. |
All four browser metrics are collected every 5 minutes. Browser metric charts do not
include threshold lines or notification badges. If the browser extension stops
reporting, the trend line shows a gap for that period.
The Top 5 Tabs Consuming Most Memory section appears below
the Avg Memory per Tab chart. It lists the five tabs with the highest memory usage
at the selected point in the trend, showing the full page URL and memory in MB.
Discarded or suspended tabs display approximately 0 MB and are labeled as
(suspended). Select the section header to expand or collapse the list.
The list updates every 30 seconds, correlated with the Avg Memory per Tab
trend.
