The setting of this variable determines which types of messages are stored in the lastlog. If ALL is specified, everything that shows up on the screen is saved in the lastlog, except DCC mesages, which have to be explicitly set. eg, to get everything, use
/SET LASTLOG_LEVEL DCC,ALL
. If NONE is specified, nothing is saved in the lastlog. The <level> specification can be one of the following: PUBLIC Channel conversation MSGS Private messages NOTICES NOTICEs WALLS WALLs WALLOPS WALLOPs NOTE NOTEs OPNOTES Operator notifications SNOTES Server notices ACTIONS In and outgoing CTCP ACTION lines USERLOG1 Reserved for the user USERLOG2 Reserved for the user USERLOG3 Reserved for the user USERLOG4 Reserved for the user DCC DCC connections BEEP Beeps HELP Any help text CRAP Anything not covered by the above categories You can combine these on a command line to make the lastlog save just what you want. Also, by putting a - before any level, you remove that one from the list. For example, if you wish to save everything except NOTEs and all that CRAP, you could do: SET LASTLOG_LEVEL ALL -NOTE -CRAP which is the same as doing: SET LASTLOG_LEVEL PUBLIC MSG NOTICE WALL WALLOP OPNOTES ACTIONS SNOTES
