Functions of Monitoring
You must monitor a system to ensure that it is operating properly and to recognize
when corrective action is required. By monitoring a system, you can:
•
Verify whether components are currently up or down
•
Be quickly notified of error conditions, state changes, and threshold conditions that
have been exceeded or are reaching their limits
•
View a chronological list of events that can help with problem diagnosis and
resolution
•
Determine how much of a particular resource is being used; for example,
processor capacity, disk or file space, or communications line bandwidth
•
Find performance problems that can affect the users of the system
•
Make better use of existing resources
•
Ensure that products such as HP NonStop SQL/MP, HP NonStop SQL/MX, HP
NonStop Transaction Management Facility (TMF), and Pathway are available
•
Prevent many problems and outages from occurring
Monitoring Tasks
Regardless of the shift you work, certain areas of your hardware and software
environment need to be checked on a regular basis. This subsection provides
guidelines that will enable you to determine the general areas you should monitor.
Working With a Daily Checklist
A good method for ensuring that certain areas of your operations environment are
monitored is to develop a checklist. Monitor these items on a system frequently. At
least daily, monitor:
•
OSM Service Connection GUI
•
Event messages
•
Alarms
•
Problem incident reports
•
The status of all system components
•
The status of processes
•
The status of all applications
•
The performance of processors, disks, and communications lines (Monitoring
performance is not discussed in this guide.)
