The ZEN OSA MONITOR for William Data Systems - OSA Monitoring Made Simple
The ZEN OSA MONITOR provides a convenient single point from which you can monitor
all the OSAs accessible to the LPAR on which ZEN is running. A single OSA drop-down
menu bar item is added when you install the ZEN OSA MONITOR and you use this to
access all of the primary display panels. Where further panels are available, these
can be accessed using links which will be clearly indicated in blue on the panel.
All link fields also have pop-up tooltips which tell you which panel will be accessed
using a left mouse-button click.
The OSA MONITOR automatically detects all accessible OSAs as soon as you start it,
and activates its basic Monitoring and History Collection functions. Other available
features such as Alert Monitoring are not activated by default so can be adjusted later
using the various OSA MONITOR panels. The available panels incorporate data extracted
from the OSA MIB and some statistics such as throughput bytes and packets and average
percentage OSA usage are extracted from your TCP/IP stack or calculated by the OSA MONITOR.
Particularly useful is the Health Check function which provides a way of dynamically
checking whether there are any problems or potential problems with your OSAs. Drill-down
options are available from the Health Check panel right to the full OSA MIB display for
the specific OSA element (channel, LPAR, Ethernet or token ring port and so on).
First Steps with the OSA MONITOR
When the ZEN OSA MONITOR is first started it automatically detects all the OSAs on the
LPAR on which it is running. It adds these dynamically to your ZEN OSA MONITOR Configuration,
with History Collection activated for each OSA. This means that you have no configuration
to do for local OSAs if you are content for the OSA MONITOR to capture history and do no
alerting for your local OSA devices.
Although the OSA MONITOR can detect the OSAs on your local system, it cannot do this for
other LPARs. Therefore, if you are sharing the OSA and want a ‘global’ view of the throughput
statistics for the OSA across all LPARs that share the device, you will need to add the other
LPARs using the OSA Configuration panel. IP stack interfaces sharing the same OSA are
associated by using the same user-defined name for each interface.
Also, if you have particular requirements, for example, you do not want to collect
History Data for one or more of your OSAs, and especially if you want to activate the
Alert Monitoring function, the OSA Configuration panel is the place to do this. You
can also delete an OSA from the Configuration should you not want to monitor it at all.
The OSA Configuration panel, and all other panels relating to the administration of this
ZEN component, are accessed using the ‘OSA Admin’ menu item which will be available from
the main ‘Admin’ item in ZEN’s menu bar.
When you make changes to the Configuration you need to save them so that they will hold
across OSA MONITOR restarts. The ZEN OSA MONITOR will always use a saved Configuration
rather than using its auto-discovery mode so your personal preferences will always be honored.
As well as verifying that your OSA configuration is as you require, there are some other
settings that you may want to review: the History Data Sampling interval, OSA contact timeout
period, and History Graph refresh rate. These are available for review and update from the
‘OSA Settings’ panel. The OSA MONITOR is shipped with reasonable values for all of these
settings so you can leave them as they are without any fear of the supplied values causing
Once this basic setup is done, a good starting place for checking your OSAs are the
OSA Summary and OSA Device Information panels. It is also a good idea to access the
Health Check panel since this provides you with the means to do a dynamic check on
the current status of your OSAs.
