描述

Use Case

I want to use the socket_listener to join and receive messages from Source-Specific-Multicast (SSM) groups using IGMPv3.

Expected behavior

When the socket_listener is configured with a specific "multicast_source" and a multicast "service_address", I expect telegraf to join the multicast group using IGMPv3 "IP_ADD_SOURCE_MULTICAST".

Actual behavior

Currently telegraf's socket_listener can only join Any-Source-Multicast (ASM) groups using "IP_ADD_MEMBERSHIP". No SSM messages can be received as SSM requires listeners to join using the correct join request.

研究方向
Investigate the socket listener plugin in Telegraf, specifically the code that handles multicast joins (likely using syscall.Setsockopt). Research Go's net package for IP ADD SOURCE MEMBERSHIP (syscall.IP ADD SOURCE MEMBERSHIP) and how to implement IGMPv3. Review existing multicast implementation to understand the structure. Test on Linux with a known SSM source. Look for any related issues or PRs in the repository.
