I converted this to bps (by multiplying 1000) and entered the data in rrdtable. Then I used rrdgraph to display the CURRENT throughput. I expect that the CURRENT throughput would be the same as the input data but the CURRENT throughput (in kbps) displayed in rrdgraph is different from the input data. Your help would be greatly appreciated. Hi Judith, If you update your rrd file exactly on step boundaries, the output data will be exactly your input data. So if you want your output data exacly, make sure your timestamp on update is exactly e.g. 12:00:00 and not 12:00:02. When the update timestamp is slightly off, rrdtool compensates the input value for that, because internally it doesn't store your update time. So, in effect, rrdtool compensates for my sloppy system where cron jobs don't run EXACTLY on time. That is probably why you don't see your input values exactly on output.

[rrd-users] Fw: Changing default font on a Windows system

If the two of you disagree, well no wonder I'm confused! If there is some reason I don't understand that you'd like the freedom to change this behaviour, and therefore would prefer to leave it undocumented? I don't mind submitting a .pod patch e.g. to doc/rrdfetch.pod documenting the current behaviour, if that is what we should stick with. Something along the lines of Alex's examples. For my script to break for unpredictable and undocumented reasons - well that *is* some small harm to me, because my script needs the data from exactly the N last good samples, not N-1 or N+1. And until I discovered the '+1' trick I didn't know how to do that. Would such a documentation patch be considered?

Hi Peter, Aha! Thanks for that - at least I kn= ow why it's not working now! I can use the --font option (and have done successfully), but as I have about500 graphs I don't *really* want to have to (a) modify each of those config lines, and (b) add that much extra data to the batch file that runs. That, after all, is the beauty of a default! Is there any way of getting either a simple config file that is read dynamically, or else having someone point me to a dummies guide to compilingRRDTool etc for Windows? Thanks!

[rrd-users] Re: How are --start and --end supposed to behave?
Hi Peter, what Alex says about time stamps I agree with (I think), so if you see data with a time stamp then this means that it is valid for the interval ending at that point in time so if the time stamp says 11:00 then the data associated with it is valid between 10:55 and 11:00 (assuming a 300 second step) As for the amount of data fetch returns, the intended behavior is for it to return enough data to 'cover' the requested time interval at a resolution equal or better than requested ... if you have a suggestion for a documentation change to better convey this intention, please send it my way. cheers Tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten http://it.oetiker.ch [EMAIL PROTECTED] ++41 62 213 9902 -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdminhttp://lists.ee.ethz.ch/lsg2.cgi
[rrd-users] rrdtool 1.2.17 is out
Hi Users, It seems that the stricter parsing for string formatting escapes I introduced in 1.2.16 has interesting side effects. Until now, any \X sequence where X was not one of the documented escapes was treated as \l this lead some people to believe that \n was a valid sequence. There was even contributed documentation in the RRDtool distro suggesting as much. I have therefor release 1.2.17 with the sole change that \n is now a valid and documented alias to \l. http://oss.oetiker.ch/rrdtool/pub cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten http://it.oetiker.ch [EMAIL PROTECTED] ++41 62 213 9902 -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdminhttp://lists.ee.ethz.ch/lsg2.cgi
