Add more detailed metric logging for V3 with dashboards.

HOW TO GET STARTED

So this is where the MLS endpoints are defined:

xmtp-node-go/pkg/mls/api/v1/service.go

Line 144 in faadec1

func (s *Service) FetchKeyPackages(ctx context.Context, req *mlsv1.FetchKeyPackagesRequest) (*mlsv1.FetchKeyPackagesResponse, error) {

and identity endpoints:

xmtp-node-go/pkg/identity/api/v1/identity_service.go

Line 78 in 987ef53

func (s *Service) PublishIdentityUpdate(ctx context.Context, req *api.PublishIdentityUpdateRequest) (*api.PublishIdentityUpdateResponse, error) {

You can add any logging you might be interested in, might also be worth comparing this with any logging we might have in the old (non-MLS) endpoints:

xmtp-node-go/pkg/api/message/v1/service.go

Line 129 in faadec1

log := s.log.Named("publish").With(zap.String("content_topic", env.ContentTopic))

You can also look through metrics for the old service in our dashboards, and try to recreate them for MLS: https://app.datadoghq.com/dashboard/lists
