I get this error message:
Argument "07-06-06" isn't numeric in integer ge (>=) at /usr/lib/perl5/5.8.8/Time/Local.pm line 103, <FD> line 5.
This is probably because the date format in the SAR output is not the default month-day-year format.
You should try the "-t DMY" option.
How do I concatenate data to an existing graph ?
Imagine you run "sar" and get a single output file per day. The new -C option allows you to add new values to an existing RRD file.
Is there a way to limit the size of the RRD files when I use the concatenation ?
Yes, you can add the -T #days option with the -C option.
Is there a way to generate new graphs without re-parsing the data ?
Yes, you can. Since v2.4, the main script sar2rrd.pl writes in a XML file, which contains all the necessary
parameters to build new graphs with the same RRD files. The graphs can be rebuilt with the new sar2rdd-graph.pl script.
Is there a way to generate graphs with single indicators ?
Yes, you can. The main script sar2rrd.pl allows you to generate graphs with all or some of the indicators
for the same "sar data block". Using the '-g' option, you can precisely choose what you want to generate...
