if I understand you correctly, you have a RS242 to ethernet converter.
It provides a TCP port you can connect to and once you've done that, you
receive everything the device provides on the serial interface via that
In theory it is possible to write a simple plugin which connects to that
port, listens for incoming data and writes that data to CSV files using
a) If all you want to do is write that data to a text file as-is,
writing a plugin is probably not much less work than writing a
simple program which achieves that.
b) From your formulation I guess you want to collect information about
“events”, i. e. data appears at irregular intervals. collectd
*requires* data at regular intervals, which would mean that collectd
is not the right tool for the job. I've been thinking about adding
an “event” infrastructure, so this type of data can be processes,
too. Currently, no such interface is available, though.
