Version A.03.20.01 of the Event Monitoring Service (B7609BA), includes media, license and manual. Version A.03.20.01 runs on HP-UX 11i B.11.11. It is available for HP 9000/Series 700 and 800.

Use the Event Monitoring Service (EMS), together with one or more EMS monitors, to monitor various system resources. The EMS product includes the framework and general monitors. You can configure EMS monitoring through monitoring requests. In the request, you define how and when you want to be notified about system resource events. EMS can enhance your high-availability environment by warning you about a single point of failure before it can make an application unavailable.

Monitors that register with the EMS framework are automatically discovered and displayed in the EMS interface. Monitors that use the interface can place information in the interface button, View Resource Description. All monitors come with EMS dictionary files that can be found in /etc/opt/resmon/dictionary.

EMS contains the following:

The framework: Provides discovery, configuration, and notification for EMS monitors. Depending on the monitor, EMS may actively poll or it may wait for event messages. It compares the return value with the threshold configured in the request. If it matches, the framework sends notification to the source specified, using the protocol specified.
The graphic interface: You start the EMS interface from an icon in SAM. Use the interface to create, modify, and remove monitoring requests. You can also see a list of the available resources that EMS has discovered on your system, and a list of all current configured monitoring requests.
The resls and resdata EMS utilities.
The MIB Monitors:
- HA Cluster Monitor checks the status of ServiceGuard clusters, nodes, or packages and services.
- HA Network Interface Monitor reports the status of LAN interfaces.
- HA System Resource Monitor checks the number of users, tge system load, and the amount of file system space.

EMS can be used with:

HP OpenView, ServiceGuard, and any other software that can receive SNMP traps, TCP, or UDP protocol messages
text to email, console, syslog or regular files that use text messages

Users can write their own monitors, using the EMS Developers' Kit. For more information, go to http://www.software.hp.com and click High Availability, then Event Monitoring Service Developers' Kit. The manual and software can be downloaded free from this web site.
