jianglai	0fb845e81a	Remove no quota leased warning from quota handler inactive callback ... When EPP SSL handshake is unsuccessful, #channelInactive is called but there are no quotas to return, because quotas are only leased upon the first #channelRead. There is no need to log a warning and throw an exception in this case because the handshake exception would have been thrown already. Throwing a second exception just crowds the log. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=197016756	2018-05-17 21:52:35 -04:00
jianglai	ce5baafc4a	Register quota metrics in GCP proxy ... When a quota request is rejected, increment the metric counter by one. Also makes both frontend and backend metrics singleton because all the fields they have a static. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=185146804	2018-02-20 15:39:15 -05:00
