Autonomous Digital Experience Management (ADEM) gives you a sense of the performance of an application by
assigning the app domain an
Experience Score.
ADEM
calculates the experience score for an app domain using synthetic and real user
monitoring (RUM) metrics available for the selected time period.
Synthetic Metrics Score
To calculate experience score from synthetic metrics,
ADEM uses
two key metrics:
Time to First Byte (TTFB) and
Availability.
Availability:
TTFB, composed of:
DNS Resolution Time
TCP Connect Time
SSL Connect Time
HTTP Latency
When the experience score drops below
70,
ADEM
identifies the root cause by analyzing the following segments:
ADEM calculates the synthetic metrics score every 5
minutes. If ADEM detects poor performance, it will associate a
single root cause with the application for the next 5-minute window, until the issue
is resolved.
Real User Monitoring (RUM) Metrics Score
ADEM evaluates user experience with the following RUM metrics:
Largest Contentful Paint (LCP): Measures the time taken to
render the largest visual element in the viewport.
Interaction to Next Paint (INP): Assesses interface
responsiveness by measuring how quickly the app responds to user
interactions (e.g., clicks or keypresses).
Availability:
RUM Experience Score Calculation
If Availability = 0: The application score is set to 0.
Otherwise, the score is the minimum of LCP Score and INP
Score.
Combined Experience Score
When both Synthetic and RUM metrics are available, the
experience score uses only RUM metrics.
When RUM metrics are unavailable, the experience score uses only
synthetic metrics.
