--- Comment #42 from Asher Feldman <afeld...@wikimedia.org> 2011-07-21 02:31:55 UTC --- We now have a build of varnish 3.0 with a udp logging daemon that should be transparently compatible with our squid log collection infrastructure. There are some VCL language changes in 3.0 and the bits/geo-ip vcl needs porting and testing before bits will be upgraded. Mobile is getting varnish 3.0 first in the next week or two, then bits testing can begin. I performed a days worth of local sampling internally on one of the bits varnish servers last week however and found rare 503's caused by first byte timeouts from the backend apache's (1:1000000 requests or less.) I filtered out 404's however due to the huge amount of legitimate ones being served due to malformed requests, bots, and broken bits installed on some wikis. I did just catch an interesting 404 on sq67 however, that was requested by Firefox 3.6.18 The RxURL listed is : http://bits.wikimedia.org/en.wikipedia.org/load.php?debug=false&lang=en&modules=mediawiki%21legacy%21commonPrint%7Cmediawiki%21legacy%21shared%7Cskins%21vector&only=styles&skin=vector That's a good URL except, the RxURL field doesn't contain the protocol or host portion of the url - this means it was a request for : http://bits.wikimedia.org/http://bits.wikimedia.org/en.wikipedia.org/load.php?debug=false&lang=en&modules=mediawiki%21legacy%21commonPrint%7Cmediawiki%21legacy%21shared%7Cskins%21vector&only=styles&skin=vector Not something I'd expect a 3.6 build of firefox to do - this could be an occasional bug in page rendering but it could also be due to factors outside of our control. I'm going to dig around further to see if I can find a load.php 404's that's been properly requested. 3724 SessionOpen c 209.226.31.161 50441 :80 3724 ReqStart c 209.226.31.161 50441 3365871486 3724 RxRequest c GET 3724 RxURL c http://bits.wikimedia.org/en.wikipedia.org/load.php?debug=false&lang=en&modules=mediawiki%21legacy%21commonPrint%7Cmediawiki%21legacy%21shared%7Cskins%21vector&only=styles&skin=vector 3724 RxProtocol c HTTP/1.1 3724 RxHeader c Host: bits.wikimedia.org 3724 RxHeader c User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.18) Gecko/20110614 Firefox/3.6.18 3724 RxHeader c Accept: text/css,*/*;q=0.1 3724 RxHeader c Accept-Language: en-us,en;q=0.5 3724 RxHeader c Accept-Encoding: gzip,deflate 3724 RxHeader c Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 3724 RxHeader c Keep-Alive: 115 3724 RxHeader c Proxy-Connection: keep-alive 3724 RxHeader c Referer: http://en.wikipedia.org/wiki/James_I_of_England 3724 VCL_call c recv lookup 3724 VCL_call c hash hash 3724 VCL_call c miss fetch 3724 Backend c 3775 appservers srv249 3724 TTL c 3365871486 RFC 120 1311214434 0 0 0 0 3724 VCL_call c fetch deliver 3724 ObjProtocol c HTTP/1.1 3724 ObjStatus c 404 3724 ObjResponse c Not Found 3724 ObjHeader c Date: Thu, 21 Jul 2011 02:13:54 GMT 3724 ObjHeader c Server: Apache 3724 ObjHeader c Content-Type: text/html; charset=iso-8859-1 3724 VCL_call c deliver deliver 3724 TxProtocol c HTTP/1.1 3724 TxStatus c 404 3724 TxResponse c Not Found 3724 TxHeader c Server: Apache 3724 TxHeader c Content-Type: text/html; charset=iso-8859-1 3724 TxHeader c Content-Length: 342 3724 TxHeader c Date: Thu, 21 Jul 2011 02:13:54 GMT 3724 TxHeader c X-Varnish: 3365871486 3724 TxHeader c Age: 0 3724 TxHeader c Via: 1.1 varnish 3724 TxHeader c Connection: keep-alive 3724 Length c 342 3724 ReqEnd c 3365871486 1311214434.264867306 1311214434.265794277 0.000029802 0.000903606 0.000023365 -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list Wikibugs-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
