XCF System Statistics attributes

The XCF System Statistics attributes monitors XCF signals (messages) sent between z/OS systems in the sysplex and transport class buffer utilization. The situations you create using these attributes let you identify where changes to transport class definitions can be made to optimize XCF performance and resource utilization.

Buffer Length Buffer length for the indicated transport class. Valid value is an integer.

Default Sequence A sequence number for sorting rows of this group in a meaningful order. This attribute is provided for information only. It cannot be used to create situations or queries, or to set thresholds and filters.

Managed System A sysplex in your enterprise that is being monitored by OMEGAMON XE for z/OS agents. Valid value is a character string with a maximum length of 32 bytes, in the format <plexname>:MVS:SYSPLEX.

Percent Degraded Percent of messages sent where the message length was larger than the transport class buffer length and caused degraded performance. Valid value is a percentage with one decimal point precision.

Percent Fit Percent of messages sent where the message length fit the transport class buffer length. Valid value is a percentage with one decimal point precision.

Percent Larger Percent of messages sent where the message length was larger than the transport class buffer length. Valid value is a percentage with one decimal point precision.

Percent Smaller Percent of messages sent where the message length was smaller than the transport class buffer length. Valid value is a percentage with one decimal point precision.

Signals Received Number of messages received. Valid value is an integer.

Signals Sent Number of messages sent. Valid value is an integer.

System From Name of the z/OS System where the messages originated. Valid value is an 8 character string.

System Name of the z/OS System on which data was collected. Valid value is an 8 character string.

System To Name of the z/OS System that is the destination of the messages. Valid value is an 8 character string.

Transport Class Transport class used for messages sent. Transport classes are used to segregate message traffic according to message size or performance needs, and may be used to dedicate signalling paths to particular workloads. Valid value is an 8 character string.

Times Buffer Unavailable Number of times a 'no buffer' condition occurred for the indicated transport class. Valid value is an integer.

Times Path Unavailable Number of times a 'no path' condition occurred for the indicated transport class. Valid value is an integer.
