Monitoring an OpenVMS
Galaxy with HP Availability Manager
The Availability Manager software
provides a valuable real-time view of the Galaxy system. Availability Manager
can monitor all Galaxy instances from a single workstation or PC
anywhere on the local area network. Availability Manager utilizes
a custom OpenVMS driver (RMDRIVER) that periodically gathers availability
data from the system. This information is returned to the Availability
Manager Data Analyzer using a low-level Ethernet protocol.
The Data Analyzer provides numerous views and graphs of the
system's availability characteristics. Additionally, when Availability
Manager detects one of numerous known conditions, it notifies the
user and offers a set of solutions (called fixes) that can be applied
to resolve the condition.
Every OpenVMS system comes with the Availability Manager Data
Collector (RMDRIVER) installed. To enable the collector, you must
execute its startup procedure inside SYSTARTUP_VMS.COM or manually
on each Galaxy instance you want to monitor. Enter the following
commands to start or stop the data collector:
$ @SYS$STARTUP:AMDS$STARTUP START
or:
$ @SYS$STARTUP:AMDS$STARTUP STOP
Before starting the collector, you need to specify a group
name for your Galaxy. Do so by editing the SYS$MANAGER:AMDS$LOGICALS.COM
file. This file includes a statement for declaring a group name. Choose
any unique name, making sure this file on each Galaxy instance contains
the same group name.
When using Availability Manager, OpenVMS Engineering finds
it useful to display the System Overview window and a CPU Modes
Summary Page of the Node Summary Page for each Galaxy instance.
There are a number of additional views you can monitor depending
on your specific interests. For more information about Availability
Manager, see the HP OpenVMS Availibility Manager User's Manual.
