Determining What to Monitor
As shown in Figure 5-1, multiple constraints affect a number of related objects. You
need to understand the constraints in your applications to determine which objects are
critical to those applications and, therefore, require monitoring.
Object Attributes
Next, you must identify the attributes of each object to be monitored. An attribute is a
named property of an object describing the data value held by that object. Each object
can have many attributes. Some attribute values, such as a program name or the object
file name of a server, can be static. Other attributes have values that can change
frequently; examples include the state of an object, the processor and priority of a
running process, or the end-of-file (EOF) pointer of a log file. For each object, you must
identify at least two key attributes, the object name and state.
