Step 1—Detecting and Isolating the Problem
To respond to problems quickly, operations personnel must be aware that a problem
exists. Active system monitoring can help reduce the time needed to detect and resolve
problems. Tandem provides a number of tools to help you perform the three basic tasks
of problem detection and isolation:
•
Monitoring Messages
•
Monitoring Objects
•
Monitoring Performance
