2.1. Latency Test for Connection Issues
New Latency Tester Tool
The Evergreen 3.1 Web Staff Client now includes a section called Tests linked from Administration → Workstation. The Tests page houses a simple tool that can be used to test the latency of the websocket connection between the client and the server (via the opensrf.echo service).
This page displays which Evergreen host server is being queried. Upon hitting the blue "Start Test" button for the first time, it will issue 10 sequentially fired requests in order to get a solid initial average. Clicking the button a second time will take one more measurement and recalculate the average latency. The results can be copied to clipboard for troubleshooting purposes and also cleared from display.
