Overview of Monitoring and Recovery Functions of Monitoring

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.)
