Table 42: How the PM System Determines if a Threshold Condition Is Met
If the threshold condition is composed of...
...an attribute, an operation, and a specific value,

PM Threshold Monitoring Overview
Then...
The threshold condition is absolute because the
PM system determines whether any instance of the
attribute exactly matches the threshold condition
after each sample interval elapses.
• For example, suppose that a threshold
condition for an entity is configured to check
whether an attribute for an instance is greater
than 2000. After the sample interval elapses,
the PM system, accordingly, determines
whether any instance of the attribute matches
the condition.
• The PM system generates a system logging
message for each instance of the attribute that
matches the threshold condition after the
sample interval elapses.
• If no instances of the attribute match the
threshold condition, system logging messages
are not generated for that sample interval.
