Interpreting Agent and Advisor display information

Successfully interpreting the various flags and indicators that appear in Advisor and Agent displays can help you identify configuration problems, or might help explain why workloads are not being distributed as expected. For information on each field in the Advisor and Agent displays, see z/OS Communications Server: IP System Administrator's Commands. Some portions of the displays are described in more depth in Table 1, Table 2, and the subtopics that follow.

Table 1. Summary of selected Advisor display output fields and flags
Flag or field name	Location	Description
ABNORM	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	The rate of abnormal transaction completions per 1000 total transaction completions for this application. This value is optionally provided to WLM by the application. WLM provides this value along with the server-specific recommendation on the system where the member is. For 1000 total transactions completed, it displays the number of those transactions that could not successfully complete. If the value is nonzero, WLM uses it to reduce the server-specific recommendation (WLM weight).
AVAIL	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	Indicates whether the member is available for workload balancing requests.
BASEWLM	GROUP FLAGS field of the group area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	WLM system weight recommendations were configured or specified by default for the members of this group, and are being used as a component of the net weight.
BASEWLM*	GROUP FLAGS field of the group area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	Server-specific WLM recommendations were configured or specified by default for the members of this group. However, WLM system weight recommendations are actually being used as a component of the net weight.
CP	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	When shown on the next line after ProcType, indicates the proportion that is applied against the CP weight. When shown on the line starting with RAW, indicates the raw CP weight that was returned by WLM. When shown on the line starting with Proportional, indicates the proportionally adjusted raw CP weight that was used to determine the BASEWLM or SERVERWLM composite weight.
CS WEIGHT	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	Communications Server weight. A value calculated by the Agent that owns the member, representing the health of the application with respect to its ability to process the work that has recently been received.
HEALTH	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	The general health of the application. This value is optionally provided to WLM by the application. WLM provides this value along with the server-specific recommendation on the system where the member is. If the value is less than 100, WLM uses it to reduce the server-specific recommendation (WLM weight).
LB INDEX	For the MODIFY procname,DISPLAY,LB and MODIFY procname,DISPLAY,LB,INDEX=nn commands, an output field of the load balancer area	A unique identifier assigned to a load balancer for the purpose of referencing the load balancer in subsequent operator commands
LBQ	FLAGS field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	The load balancer has quiesced the member.
NET WEIGHT	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	The weight the Advisor passes to the load balancer, representing the desirability of the member to receive additional workload requests relative to the other members of the same group. The net weight is calculated using the WLM weight and Communications Server weight.
NOCHANGE	For the MODIFY procname,DISPLAY,LB and MODIFY procname,DISPLAY,LB,INDEX=nn command output, the FLAGS field of the load balancer area	The load balancer has requested that it be sent only information about members that have changed their status or weights since the last time the load balancer received information on its members.
NODATA	FLAGS field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	A transient flag indicating that the responsible Agent has not had enough time to calculate a Communications Server weight.
NOTARGETAPP	FLAGS field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	The target application of this application member is not active.
NOTARGETIP	FLAGS field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	This is an unusable system member.
NOTARGETSYS	FLAGS field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	The Advisor is not aware of the system that owns the IP address of the member.
OPQ	FLAGS field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	The z/OS® operator has quiesced the member.
ProcType	A field of the group area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	Indicates that CP, zAAP, and zIIP proportions were configured. These proportions are applied against the processor weights to determine the composite BASEWLM weight.
PUSH	For the MODIFY procname,DISPLAY,LB and MODIFY procname,DISPLAY,LB,INDEX=nn command output, the FLAGS field of the load balancer area	The load balancer has requested to receive information from the Advisor on a scheduled basis, rather than having to poll the Advisor for the information.
SERVERWLM	GROUP FLAGS field of the group area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	Server-specific WLM recommendations are being used for the members of this group as a component of the net weight.
TRUST	For the MODIFY procname,DISPLAY,LB and MODIFY procname,DISPLAY,LB,INDEX=nn command output, the FLAGS field of the load balancer area	The load balancer will allow other system components besides itself to register members with the load balancer. The z/OS Load Balancing Advisor does not currently exploit this feature.
WLM WEIGHT	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	WorkLoad Manager weight. The value received from WLM on the system where the member is, representing the displaceable capacity of that system relative to other systems in the sysplex (system weight), or the value received from WLM representing how well the server is performing relative to its WLM policies (server-specific weight). This weight is a composite weight determined from the displayed CP, zAAP, and zIIP weights.
zAAP	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	When shown on the next line after ProcType, indicates the proportion that is applied against the zAAP weight. When shown on the line starting with RAW, indicates the raw zAAP weight that was returned by WLM. When shown on the line starting with Proportional, indicates the proportionally adjusted raw zAAP weight that was used to determine the BASEWLM or SERVERWLM composite weight.
zIIP	A field of the member area of the MODIFY procname,DISPLAY,LB,INDEX=nn command output	When shown on the next line after ProcType, indicates the proportion that is applied against the zIIP weight. When shown on the line starting with RAW, indicates the raw zIIP weight that was returned by WLM. When shown on the line starting with Proportional, indicates the proportionally adjusted raw zIIP weight that was used to determine the BASEWLM or SERVERWLM composite weight.

Table 2. Summary of selected Agent display output flags
Flag or field name	Location	Description
ANY	FLAGS field of the member area of the MODIFY procname,DISPLAY,MEMBERS command output	The target application is bound to the unspecified address, 0.0.0.0 for IPv4 or :: for IPv6.
V6	FLAGS field of the member area of the MODIFY procname,DISPLAY,MEMBERS command output	The target application was bound using the IPV6_V6ONLY socket option.
