SAP Web Dispatcher Monitoring
SAP Web Dispatcher is a software component within the SAP landscape that acts as a reverse proxy server and load balancer. Its primary function is distributing incoming HTTP(S) requests from users or clients across multiple application servers in an SAP system landscape by virtualizing/decrypting/forwarding network traffic. It also serves as a single point of entry for applications, managing and directing traffic to the appropriate backend SAP systems, while isolating internal servers from public networks for a more secure environment. Thus, SAP Web Dispatchers are often critical to an SAP customer’s ecosystem internally and externally (when deployed in a DMZ network).
Key Monitoring Metrics
Monitoring SAP Web Dispatcher involves tracking several critical parameters to ensure optimal performance and reliability within the SAP landscape.
The following key metrics should be monitored regularly:
HTTP(S) Connections Count - refers to the number of active connections handled by the SAP Web Dispatcher.
Server Load - refers to the average number of processes waiting in the system’s run queue over a certain period.
Server Stateful Request Count - refers to the number of requests that require the server to maintain information or context on any state or interaction with the client.
Server Stateless Request Count - refers to the number of requests that do not require the server to maintain information or context on any state or interaction with the client.
Server Response Time - refers to the time the SAP Web Dispatcher takes to process incoming client requests.
