gmetad sends unspecified data to carbon with graphite_path #187

Open jillr opened 9 years ago

jillr commented 9 years ago

On Ubuntu 14.04 with Ganglia 3.6.0-1ubuntu2 and Graphite 0.9.12-3, "graphite_path" in gmetad.conf is effectively non-functional as tested with "customer.gmetad", "customer.gmetad.%s", "customer.gmetad.%s.%h.%m". Running gmetad in debug

shows a "carbon forwarding ready to send..." on start and events are written to rrds, however only "unspecified" metrics are sent to carbon and I can't determine what these data are. Swapping out for "graphite_prefix customer.gmetad" works as expected.

packet captures and stack traces can be uploaded/linked if helpful.

If you can attach the packet captures and stack traces that would be helpful.

Sounds similar to #175

Does sound similar, dup me away if appropriate.
strace from today, changed setting in gmetad back to graphite_path and restarted: https://gist.github.com/jillr/8570ec5be616c66ce46b pcap from Tuesday: https://mega.co.nz/#!2EE2wTJQ!pY9ZK62QRM9aLfo3z7qPlSsYjWO5PzQDgprNU6d0lgk
