NAME
rasqlinsert - write argus(8) data into mysql database tables.
SYNOPSIS
rasqlinsert [raoptions] [-- filter-expression]
DESCRIPTION
Rasqlinsert writes argus data into a mysql database.
The principal function of rasqlinsert is to insert and update flow data attributes, into a MySQL
database table. Using the same syntax and strategies for all other ra* programs, rasqlinsert creates
databases and database tables, based on the print specification on the either the command-line or the
.rarc file.
The concept is that where a ra* program would print fields to standard out in ascii, rasqlinsert will
insert those fields into the database as attributes. The flow key, as defined by the "-m fields" option,
provides the definition of any keys that would be used in the schema. A "-m none" option, will remove
the use of any DBMS keys for inserted data, and is the method to use when inserting streaming,
unprocessed, primitive argus data into a database table.
The schema is important for database utility and performance. You can use MySQL querys against the
attributes that you insert into the tables, such searching and sorting on IP addresses, time, packet
counts, etc.... While rasqlinsert does not limit you to the number of attributes (columns) per record
you provide, the RDBMS performance will quide you as to how many fields are useful.
Rasqlinsert by default, includes the actual binary argus 'record' in the schema, and inserts and updates
the binary record when needed. This enables a large number of fucnctions that extend beyond simple RDBMS
schema's that are useful. Adding the 'record' is expensive, and some will elect to not use this feature.
This can be controlled using the option '-s -record' as a print field option in the standard ra.1 command
line. When the 'record' attribute is present, rasql.1 can read the records directly from the database,
to provide additional processing on the database table contents.
When keys are used, the database will enforce that any insertions meet the relaitional requirements, i.e.
that the keys be unique. This requirement demands a sense of caching and key tracking, which rasqlinsert
is specifically designed to provide.
Rasqlinsert by default, will append data to existing tables, without checking the schema for consistency.
If your schema has keys, and you attempt to append new records to an existing table, there is a high
likelyhood for error, as rasqlinsert will attempt to insert a record that collides with an existing flow
key. Use the "-M cache" option to cause rasqlinsert to reference the table contents prior to aggregation
and insertion.
The binary data rasqlinsert inserts by default, is read using rasql.
RASQLINSERT SPECIFIC OPTIONS
Rasqlinsert, like all ra based clients, supports a number of ra options including filtering of input
argus records through a terminating filter expression. Rasqlinsert(1) specific options are:
-M cache
This causes rasqlinsert to use the database table as its persistent cache store. This mechanism is
used to control memory use when dealing with large amounts of data and flow keys.
-M drop
This causes rasqlinsert to drop any pre-existing database table that has the same name as the target
table name, on startup.
INVOCATION
This invocation writes aggregated argus(8) data from the file into a database table. The standard 5-tuple fields, 'saddr daddr proto sport dport' are used as keys for each entry. rasqlinsert will aggregate all the data prior to inserting the data into the database: rasqlinsert -r file -w mysql://user@localhost/db/table Because aggregation can require a lot of memory, rasqlinsert provides an option '-M cache' to have rasqlinsert use the database table as the persistent cache store for the aggregation. With this example, the standard 5-tuple fields, ´saddr daddr proto sport dport' are still used as keys for each entry, but rasqlinsert will aggregate data over short spans of time as it reads the data from the file, and then commit the data to the database. If additional data arrives that matches that unique flow, rasqlinsert will fetch the entry from the database, aggregate, and then update the data entry in the database. rasqlinsert -M cache -r file -w mysql://user@localhost/db/table rasqlinsert can provide the same function for streaming data read directly from an argus data source. This allows rasqlinsert to reassemble all status records for an individual flow, such that the resulting table has only a single entry for each communciation relationship seen. rasqlinsert -M cache -S argus -w mysql://user@localhost/db/table This invocation writes argus(8) data from the file into a database table, without aggregation, by specifying no relational key in the data. rasqlinsert -m none -r file -w mysql://user@localhost/db/table This invocation writes argus(8) data from the stream into a database table, without modification. rasqlinsert -m none -S argus -w mysql://user@localhost/db/table This invocation writes argus(8) data from the stream into a daily database table, without modification. rasqlinsert will generate table names based on time and insert its data relative to the timestamps found in the flow records it processes. In this specific example, "-M time 1d" specifies daily tables. rasqlinsert -m none -S argus -w mysql://user@localhost/db/table_%Y_%m_%d -M time 1d
