eG Monitoring
 

Measures reported by WDispServListTest

For each destination connected to the SAP Web Dispatcher, this test reports the current operational state, load, the number of connections, requests made to this destination etc.

Outputs of the test : One set of results for each System:Destination of the SAP Web Dispatcher being monitored

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
state Indicates whether/not this destination is valid.   The values reported by this measure and their numeric equivalents are available in the table below:

Measure Value Numeric Value
No 0
Yes 1

Note:

This measure reports the Measure Values listed in the table above while indicating whether /not this destination is valid. However, in the graph of this measure, this measure is indicated using only the Numeric Values listed above.

capacity Indicates the current capacity value for this destination. Number SAP Web dispatcher needs information about the capacity of a server in order to balance its workload in relation to the other servers. The capacity is used as an estimated value of the actual “power” of an application server.

Each application server has a capacity value for each of the services it provides (ABAP, Java). The number following DIA= or LB= is the capacity value for ABAP or Java.

For a destination in an ABAP system, the value of this measure is the number of configured work process and for a destination in a JAVA system, the value of this measure is the number of configured server nodes.

The value of this measure is taken into account by the SAP Web Dispatcher during load balancing.
load Indicates the current load on this destination. Number The value of this measure and the Capacity measure is used during load balancing of the SAP Web Dispatcher.
curr_conn Indicates the current number of HTTP connections to this destination. Number If the value of this measure is close to the value set against the wdisp/HTTP/ max_pooled_con parameter, then it indicates that the SAP Web Dispatcher is handling too much of load and will not be able to accept new connections anymore.
perc_curr_conn Indicates the percentage of HTTP connections to this destination. Percentage This measure is the ratio of the curr_conn to the maximum number of HTTP connections setting.
sec_cur_conn Indicates the current number of HTTPS connections to this destination. Number If the value of this measure is close to the value set against the wdisp/HTTPS/ max_pooled_con parameter, then it indicates that the SAP Web Dispatcher is handling too much of load and will not be able to accept new connections anymore.
per_sec_conn Indicates the percentage of HTTPS connections to this destination. Percentage The value of this measure is the ratio of the sec_cur_conn to the maximum number of HTTPS connection setting.
req_stateless Indicates the current number of stateless requests to this destination. Number Stateless requests are the requests that are assigned to the next application server in the queue in accordance with load balancing.
req_group Indicates the number of requests for groups in this destination. Number  
req_stateful Indicates the current number of stateful requests to this destination. Number If a stateful request is made, the system selects the application server that should process the transaction.
resptime_last Indicates the average time taken by a request to this destination. Seconds  
pingtime_last Indicates the most recent response time for a ping request to this destination.   The value of this measure can be used to detect overall load trends for the destination. A sudden/gradual increase in the value of this measure indicates bottlenecks in the destination.
