Provided that your archives have the historical data, this is definitely
One way to do this is to setup your data definitions with the correct time
frame and then set the --start and --end parameters for your graph.
Step 1: Setting up the data definitions
#(Keep in mind, "myrrd.rrd" and "latency" below are arbitrary values)
#Data for last month
#Data for 2 months ago
#Data for 3 months ago
If you intend to only plot one month per graph, you can just set your
--start and --end parameters accordingly as you were doing before. If you
would like to transpose several months on to the same graph (for example,
the last 3 months) you can then use the shift function to set the Data
definitions in the correct time frame. The link from Alex's website
provides a great example on how to do this:
I hope this helps.
