[Xymon] Xymon Digest, Vol 14, Issue 27

[James McDonald]

Hi again,


I found a Xymon config file which seems to hold the default setup for the
RRD graphs created within Xymon (rrddefinitions.cfg).  The contents look
like this:


# 576 datapoints w/ 5 minute interval = 48 hours @ 5 min avg.

RRA:AVERAGE:0.5:1:576

# 576 datapoints w/ 6*5 minute averaged = 12 days @ 30 min avg.

RRA:AVERAGE:0.5:6:576

# 576 datapoints w/ 24*5 minute averaged = 48 days @ 2 hour avg.

RRA:AVERAGE:0.5:24:576

# 576 datapoints w/ 288*5 minute averaged = 576 days @ 1 day avg.

RRA:AVERAGE:0.5:288:576


Would I be correct saying that if I *add / append* the following lines,
this would include the LAST value to all new graphs created still keepign
the AVERAGE?

 # 576 datapoints w/ 5 minute interval = 48 hours @ 5 min avg.

RRA:LAST:0.5:1:576

# 576 datapoints w/ 6*5 minute averaged = 12 days @ 30 min avg.

RRA:LAST:0.5:6:576

# 576 datapoints w/ 24*5 minute averaged = 48 days @ 2 hour avg.

RRA: LAST:0.5:24:576

# 576 datapoints w/ 288*5 minute averaged = 576 days @ 1 day avg.

RRA: LAST:0.5:288:576


Thanks,
James
