The Event Monitoring Service (EMS) isa software product you can use to
request notification when some resource reaches a certain level. You
install an EMS monitor, then configure a monitoring request in EMS,
specifying how and when you want to be notified. EMS enhances your
high-availability environment by warning you before a single point of
failure can stop availability.
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. Most monitors place text information in one of the EMS
dictionary files in the /etc/opt/resmon/dictionary directory when
they are installed.
EMS contains the following:
• The framework: Once a monitoring request is configured, the
framework receives status from the monitor. 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 all the monitors that EMS
discovered on your system, and a list of all current configured
monitoring requests.
