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
Down or nonresponding CPUs
Down or nonresponding subsystems
Down or nonresponding network nodes
Nonresponding or hung devices
Nonresponding or hung applications
Audible Alert State Threshold Drop-Down List
The Audible Alert State Threshold drop-down list controls whether an audible alert is
sounded when a certain state threshold is reached.
When you select No Audio, audible alert thresholds are disabled.
When you select an audible alert state threshold, an audible alert is sounded if an
object changes to that state. For example, if you set the audible alert state threshold to
the Down state, an audible alert is sounded if any object changes to Down. State
