Version A.03.20.01 of High Availability Monitors (B5736DA)
includes media, license, and manual. Version A.03.20.01 runs on
HP-UX 11i. The following high-availability monitors are included
in this bundle:
HA Database Monitor checks the status of Oracle
8 databases and Informix 7 and their application servers.
HA Disk Monitor checks the status of LVM managed disks
and detects disconnected busses, power-failed or missing disks,
and stale or missing mirrors. It provides summary status for both
physical and logical volumes in a volume group and for individual
status for each disk and logical volume.
The MIB Monitors:
HA Cluster Monitor checks the status of ServiceGuard clusters, nodes,
packages, and services.
HA Network Interface Monitor reports the status of LAN interfaces.
HA System Resource Monitor checks the number of users, the system
load, and the amount of file system space.
The High Availability Monitors (HA Monitors) bundle depends
on, and includes, the Event Monitoring Service (EMS) (B7609BA).
When you install HA Monitors, the install process automatically
installs EMS.
The Event Monitoring Service has two main parts:
The EMS graphical user interface (GUI)
that runs under SAM and allows you to create, modify, and remove
monitoring requests. It also displays a list of all current monitors
and monitoring requests.
The EMS framework queries monitors, accepts status
messages, interprets them according to your configured monitoring
requests, and sends notification when and where you request.
Define monitoring requests through either the EMS GUI or with high-availability
software, such as MC/ServiceGuard and ServiceGuard OPS Edition. The EMS framework
(either through the EMS GUI or through MC/ServiceGuard) shows you a list
of all the configured monitoring requests. To add a monitoring request,
you navigate through the list of discovered and available resources.
Using either the MC/ServiceGuard or the EMS GUI you can configure more
than one request for each HA Monitor. For example, you may want to
send notification to syslog at one value and also send an email message
at another value.
All HA Monitors can be used with enterprise system management software
such as HP OpenView.
To use HA Monitors using the EMS GUI:
Log on to the system as root and enter sam to open the HP-UX System Administration Manager.
In SAM, you double-click an icon to open Resource Management, then
double-click another icon to start EMS.
Use the EMS GUI to configure a monitoring request
to warn you before a failure. This warning gives you time to take
action to prevent application downtime.
To use HA Monitors using the MC/ServiceGuard or ServiceGuard OPS Edition:
Log on to the system as root and enter sam. In SAM, double-click the icons to open Volume
Groups (/vg) or Databases (/rdbms).
Through MC/ServiceGuard or ServiceGuard OPS Edition you
can configure an HA Monitor's resource as part of a package
dependency. If the resource fails, MC/ServiceGuard may restart the package
on the local system or an alternate system.
