[BUG] nvidia_triton integration fails on IPv6 clusters due to unbracketed hostname parsing

[raouf-aghrout]

In nvidia_triton/check.py, the check derives the server info URL by calling urlparse(endpoint).hostname. For IPv6 addresses, hostname returns the raw IP without square brackets. When the check appends the port (e.g., :8000/v2), it creates an invalid URI, causing urllib3 to throw a LocationParseError / AttributeError.

Workaround identified: Setting collect_server_info: false allows the check to proceed with core metrics only.

For example:
