How Octopussy works

Logs received by your Octopussy server are handled by 3 modules in that order:

  • rsyslog/syslog-ng
  • octo_dispatcher
  • octo_parser(s)

Logs received by your rsyslog/syslog-ng are forwarded to octo_dispatcher.

octo_dispatcher dispatchs these logs in each device directories like this:

/var/lib/octopussy/logs/<devicename>/Incoming/<YYYY>/<MM>/msg_<HH>h<MM>_<xx>.log

Each octo_parser(s) (one octo_parser by Device) detects new files in previous directory, and if it maches Service(s) pattern(s) defined for this Device, then sort logs from these files in directories like this:

/var/lib/octopussy/logs/<devicename>/<servicename>/<YYYY>/<MM>/msg_<HH>h<MM>.log.gz

else if it didn't match any Service pattern(s) defined for this Device, it saves logs in these directories:

/var/lib/octopussy/logs/<devicename>/Unknown/<YYYY>/<MM>/msg_<HH>h<MM>.log.gz

Note: So, you can not create Service named 'Incoming' or 'Unknown'.
