Tips for Hardware Monitoring

Here are some tips for using hardware monitoring.

✓Keep hardware monitoring enabled to protect your system from undetected failures. Hardware monitoring is an important tool for maintaining high-availability on your system. In a high-availability environment, the failure of a hardware resource makes the system vulnerable to another failure. Until the failed hardware is repaired, the backup hardware resource represents a single-point of failure. Without hardware monitoring you may not be aware of the failure. But if you are using hardware monitoring, you are alerted to the failure. This allows you to repair the failure and restore high-availability as quickly as possible.

✓Integrate the peripheral status monitor (PSM) into your MC/ServiceGuard strategy. An important feature of hardware monitoring is its ability to communicate with applications responsible for maintaining system availability, such as MC/ServiceGuard. The peripheral status monitor (PSM) allows you to integrate hardware monitoring into MC/ServiceGuard. The PSM gives you the ability to failover a package based on an event detected by hardware monitoring. If you are using MC/ServiceGuard, you should consider using the PSM to include your system hardware resources in the MC/ServiceGuard strategy. In addition, the necessary notification methods are provided for communicating with network management application such as HP OpenView.

✓Utilize the many notification methods available. The notification methods provided by hardware monitoring provide a great deal of flexibility in designing a strategy to keep you informed of how well your system hardware is working. The default monitoring configuration was selected to provide a variety of notification for all supported hardware resources. As you become familiar with hardware monitoring, you may want to customize the monitoring to meet your individual requirements.

✓Use email and/or textfile notification methods for all your requests. Both of these methods, which are included in the default monitoring, receive the entire content of the message so you can read it immediately. Methods such as console and syslog alert you to the occurrence of an event but do not deliver the entire message. You are required to retrieve the message using the resdata utility, which requires an additional step.

✓Use the `All monitors' option when creating a monitoring request. This applies the monitoring request to all monitors. This has the benefit of ensuring a new class of hardware resource added to your system will automatically be monitored. This means that new hardware is protected from undetected hardware failure with no effort on your part.

✓Easily replicate your hardware monitoring on all your systems. Once you have implemented a hardware monitoring strategy on one of your system, you can replicate that same monitoring on other systems. Simply copy all of the hardware monitor configuration files to each system that will use the same monitoring. The monitor configuration files live in /var/stm/config/tools/monitor. Of course, you must have installed hardware event monitoring on each system before you copy the configuration files to it. Be sure to enable monitoring on all systems.
