This virtual server gives an example of +# using radrelay functionality inside of the server. +# +# In this example, the detail file is read, and the data +# is put into SQL. This configuration is used when a RADIUS +# server on this machine is receiving accounting packets, +# and writing them to the detail file. +# +# The purpose of this virtual server is to de-couple the storage +# of long-term accounting data in SQL from "live" information +# needed by the RADIUS server as it is running. +# +# The benefit of this approach is that for a busy server, the +# overhead of performing SQL queries may be significant. Also, +# if the SQL databases are large (as is typical for ones storing +# months of data), the INSERTs and UPDATEs may take a relatively +# long time. Rather than slowing down the RADIUS server by +# having it interact with a database, you can just log the +# packets to a detail file, and then read that file later at a +# time when the RADIUS server is typically lightly loaded. +# +# If you use on virtual server to log to the detail file, +# and another virtual server (i.e. this one) to read from +# the detail file, then this process will happen automatically. +# A sudden spike of RADIUS traffic means that the detail file +# will grow in size, and the server will be able to handle +# large volumes of traffic quickly. When the traffic dies down, +# the server will have time to read the detail file, and insert +# the data into a long-term SQL database. +# +# $Id$ +# +###################################################################### + +server buffered-sql { + listen { + type = detail + + # The location where the detail file is located. + # This should be on local disk, and NOT on an NFS + # mounted location! + # + # On most systems, this should support file globbing + # e.g. "${radacctdir}/detail-*:*" + # This lets you write many smaller detail files as in + # the example in radiusd.conf: ".../detail-%Y%m%d:%H" + # Writing many small files is often better than writing + # one large file.

If the database is + # overloaded, then bad things can happen. + # + # The server will keep track of how long it takes to + # process an entry from the detail file. It will + # then pause between handling entries. This pause + # allows databases to "catch up", and gives the + # server time to notice that other packets may have + # arrived. + # + # The pause is calculated dynamically, to ensure that + # the load due to reading the detail files is limited + # to a small percentage of CPU time. The + # "load_factor" configuration item is a number + # between 1 and 100. The server will try to keep the + # percentage of time taken by "detail" file entries + # to "load_factor" percentage of the CPU time. + # + # If the "load_factor" is set to 100, then the server + # will read packets as fast as it can, usually + # causing databases to go into overload. + # + load_factor = 10 + + # + # Set the interval for polling the detail file. + # If the detail file doesn't exist, the server will + # wake up, and poll for it every N seconds. + # + # Useful range of values: 1 to 60 + # + poll_interval = 1 + + # + # Set the retry interval for when the home server + # does not respond.
