Overview of Monitoring and Recovery

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.)
