* Switch to the 'parser' view mode when the user hits ';' so they
|
||||
* can easily see what columns are available.
|
||||
*
|
||||
* select * from logline;
|
||||
* select itemfrom(csv_key, 0) from logline;
|
||||
* select itemfrom(csv_key, -1) from logline;
|

* select itemfrom(dict_key, "key") from logline;
|

* select itemfrom(dict_key, "key[0]") from logline;
|
||||
* select itemfrom(csv_key, 0:3) from logline; support splices ?
|
||||
*
|
||||
* Add a command to create a logline table with a given name so the user can
|
||||
* do joins across the tables:
|
||||
*
|
||||
* create-logline-table sudo_logline
|
||||
* select * from logline, sudo_logline where sudo_logline.COMMAND=logline.COMMAND;

*
|

* select timestmap / 60 as minute, sc_status, count(*) from access_log
|
||||
* group by minute, sc_status
|
||||
* order by minute, sc_status desc;
|
||||
* (use group_concat() here?)
|
||||
*
|
||||
* The "itemfrom()" function parses the group and lets you specify an
|
||||
* expression to query the contents.
|
||||
*
|
||||
* For 'report-on' command:
|
||||
* 'report-on PWD'
|
||||
* select PWD,count(*) as amount from logline group by PWD order by amount desc;
|
||||
* 'report-on num_col num_col2'
|
||||
* select avg(num_col),stddev(num_col),... from logline;
|
||||
* Instead of a command, we should automatically create views with the
|
||||
* relevant select statements.
|
||||
*
|
||||
* Add a tojson() aggregate function to sqlite:
|
||||
* select foo,tojson(bar) group by foo;
|
||||
*
|
||||
* 1 ["a", "b", "c"]
|
||||
* 2 ["d", "e", "f"]
|
||||
*
|
||||
* We should automatically detect sqlite files provided on the command line
|
||||
* and attach the database.
|
||||
*
|
||||
* add a 'metadata' view that has all the metadata crud (sql tables/log)
|
||||
*
|
||||
* Add support for sqlite_log that writes to a temp file and is displayed in the
|
||||
* metadata view.
|
||||
*
|
||||
* Add a function that bookmarks all lines in the log view based on line_numbers
|
||||
* in the sql query result.
|
||||
*
|
||||
* select line_number from logline where A="b";
|
||||
* hit 'y/Y' to move forward and backwards through sql results
|
||||
* hit 'R' key and all the lines are bookmarked
|
||||
*
|
||||
* add path manipulation functions like basename, dirname, splitext
|
||||
*
|
||||
* use the vt52_curses emulation to embed a editor for editing queries. For
|
||||
* example, you could hit 'ctrl+;' and it would split the window in half with
|
||||
* the bottom being used for nano. When the file was written, lnav should
|
||||
* notice and do a 'prepare' on the sql to make sure it is correct.
|
||||
*
|
||||
* Maybe add other tables for accessing lnav state. For example, you could do
|
||||
* a query to find log lines of interest and then insert their line numbers
|
||||
* into the 'bookmarks' table to create new user bookmarks.

generic_log 'Generic' log format. This table contains messages

|

DYNAMIC LOG LINE TABLE (experimental)
|
||||
----------------------
|
||||
|
||||
(NOTE: This feature is still very new and not completely reliable yet,
|
||||
use with care.)
|
||||
|
||||
For log formats that lack message structure, lnav can parse the log
|
||||
message and attempt to extract any data fields that it finds. This
|
||||
feature is available through the "logline" log table. This table is
|
||||
dynamically created and defined based on the message at the top of
|
||||
the log view. For example, given the following log message from "sudo",
|
||||
lnav will create the "logline" table with columns for "TTY", "PWD",
|
||||
"USER", and "COMMAND":
|
||||
|
||||
May 24 06:48:38 Tim-Stacks-iMac.local sudo[76387]: stack : TTY=ttys003 ;
|
||||
PWD=/Users/stack/github/lbuild ; USER=root ;
|
||||
COMMAND=/bin/echo Hello, World!
|
||||
|
||||
Queries executed against this table will then only return results for
|
||||
other log messages that have the same format. So, if you were to
|
||||
execute the following query while viewing the above line, you might
|
||||
get the following results:
|
||||
|
||||
;select USER,COMMAND from logline;
|
||||
|
||||
USER | COMMAND
|
||||
---- | -------------------------
|
||||
root | /bin/echo Hello, World!
|
||||
mal | /bin/echo Goodbye, World!
|
||||
|
||||
|
||||
The log parser works by examining each message for key/value pairs
|
||||
separated by an equal sign (=) or a colon (:). For example, in the
|
||||
previous example of a "sudo" message, the parser sees the "USER=root"
|
||||
string as a pair where the key is "USER" and the value is "root".
|
||||
If no pairs can be found, then anything that looks like a value is
|
||||
extracted and assigned a numbered column. For example, the following
|
||||
line is from "dhcpd":
|
||||
|
||||
Sep 16 22:35:57 drill dhcpd: DHCPDISCOVER from 00:16:ce:54:4e:f3 via hme3
|
||||
|
||||
In this case, the lnav parser recognizes that "DHCPDISCOVER", the MAC
|
||||
address and the "hme3" device name are values and not normal words. So,
|
||||
it builds a table with three columns for each of these values. The
|
||||
regular words in the message, like "from" and "via", are then used to
|
||||
find other messages with a similar format.
