Version A.01.00 is the first release of the EMS HA Monitors product.
Benefits
The EMS HA Monitors product enhances your high availability environment:
• EMS monitors make is easier to monitor many systems with little or no human
intervention except to fix problems. EMS monitors system resources, such as
disks, file systems, and network interfaces and sends events when these
resources reach user-defined critical levels. For example, the disk monitor can
detect disk failure and loss of redundant data and send an event to a central
location where a person can interpret the event and fix the problem.
• EMS works with a wide range of system management tools. Because it supports
a variety of protocols (opcmsg, SNMP traps, TCP, and UDP), events can be sent
to any number of system management tools, including HP OpenView’s
IT/Operations and Network Node Manager.
• The EMS framework allows you to add new monitors without having to reinstall
or reconfigure existing monitors. This includes custom monitors you write to
monitor your own applications.
• In addition to sending events to system management software, the EMS HA
Monitors product is designed to work with MC/ServiceGuard to allow a more
flexible way of adding resources as package dependencies. The A.10.10 release
of MC/ServiceGuard will support configuring EMS resources as package
dependencies.
Features
EMS contains the following:
• The disk monitor checks the status of LVM managed disks and detects
disconnected busses, power-failed or missing disks, and stale or missing mirrors.
The disk monitor provides summary status for both physical and logical volumes
in a volume group as well as individual status for each disk and link and logical
volume.
• The cluster monitor checks the status of clusters and detects failed clusters,
nodes, or packages. It is mainly for environments without ClusterView.
