I am familiar with custom formats. what I mean is (sample from IIS log) so I can query it like "select * from ... where sc-status=200" without prior knowledge what field "sc-status" is (format might change from file to file)
also, I guess log exporters may take advantage from it. #Software: Microsoft Internet Information Services 8.5 #Version: 1.0 #Date: 2017-06-26 13:09:21 *#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) cs(Referer) sc-status sc-substatus sc-win32-status time-taken* 2017-06-26 13:09:21 192.168.183.152 GET / - 808 - 10.33.41.142 - - 200 0 64 11451 2017-06-26 13:09:21 192.168.183.152 GET / - 808 - 10.33.41.142 - - 200 0 0 2378 2017-06-26 13:11:23 192.168.183.152 GET /favicon2.iso - 808 - 10.33.41.142 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+5.1;+Trident/4.0) - 404 0 2 1 2017-06-26 13:11:23 192.168.183.152 GET /favicon.iso - 808 - 10.33.41.142 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+5.1;+Trident/4.0) - 404 0 2 2 пт, 20 мар. 2020 г. в 17:54, Aleksandar Lazic <[email protected]>: > Hi. > > On 20.03.20 13:15, Илья Шипицин wrote: > > Hello, > > > > there's Microsoft LogParser. > > good thing about it, it likes self-consistent CSV logs (or TSV), when > first line is fields. > > > > it helps to change log format on the fly (for example, in IIS), so IIS > starts new log once format is changed. > > > > you can query such logs without prior knowledge of fields, because > fields are in log. > > > > I did not find such possibility in haproxy. is it supported ? > > or must yet to be done. > > You can create any custom log format which you want with `log-format` > directive. > > https://cbonte.github.io/haproxy-dconv/2.1/configuration.html#8.2.4 > https://www.haproxy.com/blog/haproxy-log-customization/ > > Do this answer your question? > > > Cheers, > > Ilya Shipitcin > > Regards > Aleks >
