NAME
pdbtool - An application to test and convert syslog-ng pattern database
rules
SYNOPSIS
pdbtool [command] [options]
DESCRIPTION
This manual page is only an abstract; for the complete documentation of
syslog-ng and pdbtool, see The syslog-ng Administrator Guide[1].
The syslog-ng application can match the contents of the log messages to
a database of predefined message patterns (also called patterndb). By
comparing the messages to the known patterns, syslog-ng is able to
identify the exact type of the messages, tag the messages, and sort
them into message classes. The message classes can be used to classify
the type of the event described in the log message. The functionality
of the pattern database is similar to that of the logcheck project, but
the syslog-ng approach is faster, scales better, and is much easier to
maintain compared to the regular expressions of logcheck.
The pdbtool application is a utility that can be used to:
· test message patterns;
· convert an older pattern database to the latest database format;
· merge pattern databases into a single file;
· dump the RADIX tree built from the pattern database (or a part of
it) to explore how the pattern matching works.
THE MATCH COMMAND
match [options]
Use the match command to test the rules in a pattern database. The
command tries to match the specified message against the patterns of
the database, evaluates the parsers of the pattern, and also displays
which part of the message was parsed successfully. The command returns
with a 0 (success) or 1 (no match) return code and displays the
following information:
· the class assigned to the message (e.g., system, violation, etc.),
· the ID of the rule that matched the message, and
· the values of the parsers (if there were parsers in the matching
pattern).
The match command has the following options:
--color-out or -c
Color the terminal output to highlight the part of the message that
was successfully parsed.
--debug-pattern or -D
Print debugging information about the pattern matching.
--message or -M
The text of the log message to match (only the $MESSAGE part
without the syslog headers).
--pdb or -p
Name of the pattern database file to use.
--program or -P
Name of the program to use, as contained in the $PROGRAM part of
the syslog message.
Example:
pdbtool match -p patterndb.xml -P sshd -M "Accepted publickey for myuser from 127.0.0.1 port 59357 ssh2"
THE MERGE COMMAND
merge [options]
Use the merge command to combine separate pattern database files into a
single file (pattern databases are usually stored in separate files per
applications to simplify maintenance). If a file uses an older database
format, it is automatically updated to the latest format (V3). See the
The syslog-ng Administrator Guide[1] for details on the different
pattern database versions.
--directory or -D
The directory that contains the pattern database XML files to be
merged.
--pdb or -p
Name of the output pattern database file.
Example:
pdbtool merge --directory /home/me/mypatterns/ --pdb /var/lib/syslog-ng/patterndb.xml
Currently it is not possible to convert a file without merging, so if
you only want to convert an older pattern database file to the latest
format, you have to copy it into an empty directory.
THE DUMP COMMAND
dump [options]
Display the RADIX tree built from the patterns. This shows how are the
patterns represented in syslog-ng and it might also help to track down
pattern-matching problems. The dump utility can dump the tree used for
matching the PROGRAM or the MSG parts.
--pdb or -p
Name of the pattern database file to use.
--program or -P
Displays the RADIX tree built from the patterns belonging to the
$PROGRAM application.
--program-tree or -T
Display the $PROGRAM tree.
Example and sample output:
pdbtool dump -p patterndb.xml -P ´sshd´
´p´
´assword for´
