1121: W3SVC performance counter HTTP site failure
The IIS World Wide Web Publishing Service is responsible for managing the HTTP protocol and HTTP performance counters. It collects HTTP-specific performance counters for web sites. It initializes the counters and receives them from HTTP.Sys, the protocol listener for HTTP. If W3SVC is not available, HTTP performance counter data cannot be gathered.
Event 1121 is generated when the World Wide Web Publishing Service failed to obtain site performance counters from HTTP.Sys.
How could you resolve this situation?
If updated performance counters are required by the web sites, restart the World Wide Web Publishing Service.
