There doesn't appear to be a fixed limit in the rrdtool source. You may still be limited by a maximum command line length or maximum parameter count in the shell or C library. > -if a timestamp:value pair is sent in an update command, but we > already have data for that timestamp slot, is the original entry left > in place, or is it replaced with the new?

Data can only be inserted into an rrd file in order of increasing timestamps. If rrdtool encounters an older timestamp than the most recent update, an error is printed and the command aborts. If you expect this to happen, you may not want to combine multiple updates in the same rrdtool update invocation. -Sam _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
