- Review manual closure requirements
- Check for orphaned alerts
Issue: Premature closure
Problem: Problem areas closing while issues persist
Solution:
- Adjust closure criteria

Frequently Asked Questions
General Questions
Q: How many alerts should be in a problem area?
A: There’s no fixed number, but follow these guidelines:
Optimal Range: 3-20 alerts per problem area
Minimum: 2 alerts (configurable)
Maximum: 50-100 alerts (to prevent unwieldy groups)
Consider: Business impact over alert count
Q: Can an alert belong to multiple problem areas?
A: Generally no, but there are exceptions:
Standard Behavior: One alert, one problem area
Exceptions:
- Different policy types (Problem Area vs Correlation)
- Different scopes (Infrastructure vs Business Service)
- Hierarchical relationships (Component vs System level)
Q: How long should time windows be?
A: It depends on your environment:
Critical Systems: 1-5 minutes
Standard Systems: 5-15 minutes
Batch Systems: 15-60 minutes
Factors: Alert volume, processing speed, business impact
Configuration Questions
Q: What’s the difference between Problem Area and Correlation?
A: Different purposes and approaches:
Problem Area:
- Groups related alerts into single problem
- Reduces noise and provides focus
- Emphasizes operational workflow
Alert Correlation:
- Identifies relationships between alerts
- Maintains individual alerts
- Emphasizes analysis and root cause
Q: How do I handle alerts from different monitoring tools?
A: Normalize and correlate across sources:
Approach:
- Standardize resource naming conventions
- Map tool-specific attributes to common schema
- Use multiple correlation methods
- Implement tool-specific rules when needed
Q: Should I group by severity?
A: Consider business impact over severity alone:
Recommended:
- Group by business service or resource relationship
- Use severity for prioritization within groups
- Allow severity escalation based on group characteristics
Avoid:
- Grouping only by severity level
- Ignoring business context
- Rigid severity-based rules
Operational Questions
Q: How do I handle alert storms?
A: Implement storm protection:
Strategies:
- Set maximum group sizes
- Implement rate limiting
- Use dynamic time windows

Q: What happens during maintenance windows?
A: Adjust behavior for planned maintenance:
Maintenance Mode Options:
- Suppress problem area creation
- Extend time windows
- Change severity thresholds
- Apply maintenance-specific rules
- Group maintenance-related alerts separately
Q: How do I handle false positives?
A: Implement feedback and learning mechanisms:
Immediate Actions:
