6. cfdcollect configuration
cfdcollect uses a simple configuration file, typically named
cfdcollect.conf and located in the /usr/local/arts/etc/
directory. cfdcollect.conf should contain two types of stanzas:
a single 'system' stanza specifying system-wide values for
cfdcollect, and one or more 'cflowd' stanzas (one for each instance
of cflowd).
6.1 system stanza
The system stanza is used to set system-wide values for cfdcollect.
There should be only one of these in cfdcollect.conf, and it
should be the first stanza. Following are descriptions of each of
the variables in the system stanza.
logFacility
Sets the syslog facility to be used for logging by cfdcollect.
dataDirectory
Sets the top-level directory in which to store ARTS data for each
router. cfdcollect actually writes into subdirectories under
dataDirectory for each router, with the subdirectories named by the IP
address of each router (corresponding to the HOST setting for routers in
cflowd.conf). For example, if you set dataDirectory
to /usr/local/arts/cflowd/data, the data for router
204.212.46.1 would wind up in the
/usr/local/arts/cflowd/data/204.212.46.1 directory.
filePrefix
Sets the file prefix to be used when writing ARTS data to files.
cfdcollect uses filenames of the form
filePrefix.YYYYMMDD to store ARTS data. Ther normal
filePrefix setting is 'arts'. Continuing with the example from
the last section, data for router 204.212.46.1 for September 23, 1998
would wind up in
/usr/local/arts/cflowd/data/204.212.46.1/arts.19980923
pidFile
Specifies the full path to the file in which cfdcollect should
store its process ID.
Example
An example system stanza is shown below. It tells cfdcollect
to syslog with the local6 facility, place data in the
/usr/local/arts/data/cflowd directory, use 'arts' as the
file prefix when creating data files, and to store its process ID
in /usr/local/arts/etc/cfdcollect.pid.
system {
logFacility: local6 # Syslog to local6 facility.
dataDirectory: /usr/local/arts/data/cflowd
filePrefix: arts
pidFile: /usr/local/arts/etc/cfdcollect.pid
}
6.2 cflowd stanza
The cflowd stanza is used to set configuration variables for an instance
of cflowd from which we want cfdcollect to retrieve
data. Following are the descriptions of each of the variables in the
cflowd stanza.
host
The host running cflowd. This may be a hostname or an IP
address.
tcpCollectPort
Sets the port to which to connect to on the host running
cflowd. This is the TCP port on which cflowd
is listening, corresponding to the TCPCOLLECTPORT setting in the OPTIONS
stanza of cflowd.conf.
minPollInterval
Sets the minimum interval between connections to cflowd. This
is not an exact interval timer, since cfdcollect processes all
cflowd instances with a single thread (serially).
Example
Following is an example cflowd stanza. It tells cfdcollect
to contact cflowd on foo.mydomain.net port 2056 every 300
seconds (5 minutes) to retrieve the tabular data from cflowd.
cflowd {
host: foo.mydomain.net
tcpCollectPort: 2056
minPollInterval: 300
}
