Problems Flashcards
How does Dynatrace determine when to trigger alerts based on performance deviations? What types of thresholds are used?
- Automated baselines
- Built-in static thresholds
Dynatrace categorizes events based on their severity level. What are the six event types, ordered from most to least severe?
Availability (most severe)
Error
Slowdown
Resource
Custom
Info (least severe)
Where in Dynatrace can you adjust the sensitivity of event alerting to fine-tune how and when alerts are triggered?
Global settings -> Anomaly detection
What are the four levels of impact that Dynatrace uses to categorize problems?
Application
Services
Infrastructure
Environment
How long does Dynatrace retain problem details for analysis after a problem is detected?
10 days
What are the 4 baselines used to distinguish between normal and anomalous situations?
Traffic
Error rate
Response time
Multidimensional
When creating baselines for applications in Dynatrace, what are the four dimensions that can be considered
User action
Geolocation
Browser
OS
What are the two dimensions that Dynatrace uses for establishing baselines for services(Service baseling)?
Service method
Service method group
How long does Dynatrace typically take to learn traffic patterns before it starts alerting on unusual traffic spikes or drops?
After a week
What condition must be met before Dynatrace starts alerting on an increase in error rates for an application or service?
After the app has run for at least 20% of a week(7 days)
What triggers Dynatrace to start alerting on an increase in response time(slowdown event) for an application or service?
After the median or the 90th percentiles degrade
How can you customize the static thresholds that Dynatrace uses for monitoring your infrastructure?
Global Settings -> Anomaly detection -> Infrastructure
What are the Dynatrace maintenance windows
one-time, daily, weekly, monthly or on a custom schedule
