LogCentral's functionnalities are described on our public site.
We explain a little more the way it works here.
The display of real time syslogs allows:
Verify the proper functionning of your system, that is to say the ingestion of logs, and seeing them arrive in real time
Filtering where you can type free text in the right-end search box
This features generates a flow of logs displayed straight in your browser. Technically we use Server Sent Events (SSE), which is an Event Stream.
This functionnality is accessible from every active location page.
