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 notiﬁedabout 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.
