[mrtg] Incoming errors only? gvolk's interface-errors.template

[Arvon Griffiths]

Now that the cfgs are being generated and since outgoing errors are always zero, is there a way to modify the template file to only log incoming errors?

 
Here's the template file:
###############################################################################
#
# interface-errors.template v20030106 by gvolk at gvolk.com ( mailto:gvolk at gvolk.com )
#
# The following is a mrtg template that can be used in conjunction with
# cfgmaker for automatically building configs for monitoring interface
# errors.
#
# Usage: cfgmaker --if-template=interface-errors.template public at router
