[Analytics] Adding fields to cache (=squid, varnish, nginx) log format ($ssl_cipher)

Hi, it seems ops received a request to add the negotiated cipher suite to the cache logs for https requests. Would it hurt any of our tools or would we expect breakage if for example $ssl_cipher from http://nginx.org/en/docs/http/ngx_http_ssl_module.html#variables got append as field #17 to the format currently described at https://wikitech.wikimedia.org/wiki/Cache_log_format ? Do we know of other reasons to veto such a change? (If I do not hear of problems until 2014-01-22, I'll let ops know that appending $ssl_cipher is ok for us) Best regards, Christian P.S.: * Webstatscollector ignores additional fields, hence should be safe. * Wikipedia zero ignores additional fields, hence should be safe. * The mobile jobs that we moved out of Hadoop some time ago and I guess are currently unused ignore additional fields, hence should be safe. -- ---- quelltextlich e.U. ---- \\ ---- Christian Aistleitner ---- Companies' registry: 360296y in Linz Christian Aistleitner Gruendbergstrasze 65a Email: christian(a)quelltextlich.at 4040 Linz, Austria Phone: +43 732 / 26 95 63 Fax: +43 732 / 26 95 63 Homepage: http://quelltextlich.at/ --------------------------------------------------------------- OpenPGP key transition from 0xEF78CCDE to 0x13C1072F: http://quelltextlich.at/openpgp-transition-0xEF78CCDE-to-0x13C1072F.txt
