Minimum State Change Monitored List
Minimum State Change Monitored List
The Minimum State Change Monitored list specifies the minimum state to be
monitored. When you select a minimum state, you are specifying the minimum state
change that ASAP monitors.
For example, if you select Warning as the minimum state change monitored, changes
into states less significant than Warning are not logged in the OSC log. In this case,
state changes to Up, Low, Medium, or High alert are not logged in the OSC log.
Maximum Change History Retained in Log List
The Maximum Change History Retained in Log list specifies the maximum number of
state changes that the OSC log retains.
When you select the maximum change history, you specify how much history is
retained in the OSC log.
For example, if you select 200 as the maximum, up to 200 of the most recent state
changes are retained in the OSC log.
The OSC log is retained in workstation memory for fast access.
Because detailed statistics are stored in the ASAP server, the OSC log is small, and
uses little workstation memory.
Late Data Integrity Check Drop-Down List
The Late Data Integrity Check drop-down list controls whether late data integrity
checking is performed and, if so, how early or late data can be before it is flagged as a
down time.
When you select Automatic, ASAP automatically determines whether data received
from each node, entity, and object is arriving in a timely manner. If not, ASAP flags the
time for the object as down time.
When you select a Late Data time, ASAP delays its Automatic late data check by that
amount. For example, if you select 30 seconds, ASAP delays its late data alert by an
additional 30 seconds. During this delay, data might arrive from the nonresponding
object. Manually specifying this value lets you account for marginal queuing delays in
your system or network.
If you select No Check, late data integrity checks are disabled. This option overrides
any Graph Time settings for individual entity Time attributes shown on the Attribute Tab
of the ASAP Property sheet. To globally disable late data checks, select this option.
HP does not recommend that you disable this option. Late Data integrity checks
performed by the ASAP client are one of the key features performed by ASAP. By
checking for late or early data, ASAP can detect many types of serious availability
outages. Anomalies detected when Late Data checks are enabled include:
•
Excessive queuing delays affecting availability
