Some custom configuration is possible through the use of the sFlowTrend-Pro properties file. Modifying this is only recommended for advanced users. The file must be editing using a standard text editor, and sFlowTrend-Pro must be restarted before any of the changes will take effect.
The properties file is called
config.prp,
and it is located in the sFlowTrend-Pro data directory (which
can be identified and changed through the sFlowTrend-Pro
→
menu selection). If the
config.prp
file does not exist in this directory, then it must first be
created.
The file is organised as a series of lines, where each line is of the form:
propertyName = value
For example,
chart.topn = 8
would change the number of entries in a top-n to 8. Note that all properties and values must be entered exactly as specified. Some of the properties that can be modified using the properties file are:
n).
The default value is 5.
true.
In this case, sFlowTrend-Pro will automatically
enable and start collecting data from the first
n
switches that it receives unsolicited (command
line configured) sFlow from, where
n
is the maximum number of switches allowed by the
software license. To control manually which
switches are enabled, set this value to
false.
If sFlowTrend-Pro is configuring the switches using SNMP to send sFlow, sFlowTrend-Pro will use this value to configure the sampling rate for all interfaces of the given ifSpeed. The default values are:
sflowtrend.samplingRate.medium = 128
sflowtrend.samplingRate.10.medium = 128
sflowtrend.samplingRate.100.medium = 256
sflowtrend.samplingRate.1000.medium = 512
sflowtrend.samplingRate.10000.medium = 1024
For example
sflowtrend.samplingRate.100.medium = 256
tells sFlowTrend-Pro to configure all interfaces with an
ifSpeed of 100 Mb/s with a sampling rate of
1 in 256. The value for
sflowtrend.samplingRate.medium
is used by sFlowTrend-Pro when configure an interface with
an ifSpeed for which a sampling rate has not been
specified. For example with the default sampling rate
settings, an interface with an ifSpeed of 1Mb/s would
be configured with a sampling rate of 1 in 128.
false
to stop the web server being started when
sFlowTrend-Pro runs. Disabling the web server also
disables the ability to integrate sFlowTrend-Pro with
other applications.
8087.
true,
which means that the web server only responds
to
localhost.
It is a good idea to restrict the web server
like this to avoid any security issues. However,
if you desire any host to be able to access the
web server, then set this to
false.
