Problem

I'm using Syslog source in UDP mode with internal metrics turned on. It turns out that the received events related metrics of the source like component_received_event_bytes_total and component_received_event_total are missing.

FYI, using Syslog source in TCP mode do have those received events related metrics.

Configuration

{
  "type": "syslog",
  "address": "0.0.0.0:514",
  "mode": "udp",
  "tls": {
    "enabled": false
  }
}

Version

@youtian001 I confirm this behavior. I have checked the source code of syslog source in udp mode - it doesn't send these metrics. I guess it's a bug and should be fixed.

I think the fix shouldn't be a difficult one - just add the required metrics in the corresponding places. The only possible caveat here - if the code is shared with something and it will interfere with other functionality. We will need to check it more carefully.
