When you define the attributes of resource monitoring, you are telling CICSPlex® SM exactly
which occurrences of one or more resource types are to be monitored and when
this monitoring is to occur. The resource monitoring attributes are based on information
provided in monitor specifications, monitor definitions, and, optionally,
monitor groups.
- A monitor specification identifies the types of
resources to be monitored and how frequently information about these resources
is to be gathered. After you associate a monitor specification
with a CICS® system, that specification is automatically installed every time the CICS system starts.
- A monitor definition qualifies the resource type
identified by a monitor specification. For example,
after creating a monitor specification that indicates the program resource
type is to be monitored, you might create a monitor definition that causes
all programs to be monitored or only those programs with names starting with
PAY.
A monitor definition also indicates which resources should be identified
to the resource status facility.
You can install a monitor definition either manually
or automatically. To be automatically installed, a monitor definition must
be part of a monitor group. Monitor definitions that are not part of a monitor
group must be manually installed.
- A monitor group is a collection of monitor definitions
that are treated as a single entity. This means that
you can install all of the monitor definitions associated with a monitor group
either by:
Note:
A monitor definition can be installed in variety of CICSPlex SM managed CICS systems.
However, not all resource types are supported in all of those systems. Therefore, CICSPlex SM verifies
that the resource to be monitored is supported in the target system prior
to installing the definition. If it is not, CICSPlex SM issues a message indicating
the definition cannot be installed because the resource is not supported.
This message is informative in nature and does not require any corrective
action.
Figure 54 illustrates the attributes of resource monitoring. In this example:
- Monitor specification EYUMOS01 designates that the CICS region, program,
and transaction resource types are to be monitored, using the monitor definitions
associated with the monitor groups EYUMOG01, EYUMOG02, and EYUMOG03.
- Monitor groups, such as EYUMOG01, activate resource monitoring during the designated
range of hours identified by the time period definition.
- Monitor definitions, such as EYUMOD01 and EYUMOD02, qualify the specific
resource information to be gathered. That is, the monitor definition EYUMOD01
indicates that only the program named PAYX is to be monitored; while EYUMOD02
indicates that any transaction identifiers starting with PAY are to be monitored.
Monitor definitions such as EYUMOD09 are not associated with any monitor group
and must, therefore, be manually installed. These definitions are useful when
you have a very specific resource occurrence you want to monitor occasionally.
