[Xymon] Creating graphs on the fly?

[Paul J R]

Hi All,

Im trying to create a graph on the fly from a custom script. Currently 
im monitoring a piece of software via an external script, and depending 
on whats happening with the software the script creates or deletes 
column's within xymon (i.e. what gets monitored by xymon changes over 
time). That all works fine, but im now trying to add/remove a graph each 
time a column is added/removed and i've found two ways of doing this so 
far (automated from the script):

1) change the test2rrd/graphs in xymonserver.cfg and add an entry in 
graphs.cfg then send my data via the "trends" data channel.
2) same as above but add an ncv variable to xymonserver.cfg and send 
data via the data channel for the column, kills off the xymon_rrd processes.

In both cases my ext script modifies xymonserver.cfg and graphs.cfg on 
the fly and im curious to know if theres a better way of doing this?
