Hi I’m sure I’m being extremely stupid here but I have tried to read the docs ;-) using the former I get entries in syslog like URL: /getHids in /usr/local/openresty/api/bin/../lib/api.pm l. 47 With the latter I get URL: /getHids I assume I need to tweak the log_format I have tried this (only reference I could find to the format string is in Log4perl) LogReport: log_format: '%a%i%m in %F at %L' But it continues to just display as before - not even with the ‘in’ or the ‘at’ as indeed does commenting it out - so I assume %a%i%m is a default Are the log_format string options defined anywhere? What have I missed? TIA config I am using logger: LogReport: log_format: '%a%i%m in %F at %L' app_name: api dispatchers: default: type: SYSLOG identity: api facility: local0 flags: "pid ndelay nowait" mode: DEBUG logsocket: host: 172.16.101.16 port: 10010 type: udp — Clive Eisen
