Generally speaking the poller will spit out a number, its cached in the temporal buffer. Then the last poller/backend in the group takes all the cached items and puts them into the RRD file.
Is the problem for the standard interface types or ones you made? > "The RRDTool files for Interface ID 15 (from Host ID 2), has > not been created by the Poller Process yet" The file might be there, that's an obvious one to check. Check also the permissions are right. Almost always this bug points to a graph problem, not a polling problem. You can send pretty much anything from the pollers and not get this problem (you get a graph of NaNs instead) The easiest way is to edit lib/api.rrdtool.inc.php. Line 57 has //debug($command); Remove the comments, try to look at your broken graph and on the webpage you should get the rrdtool graph command. On a cli paste that command (even better do it sudo/su as the www-data user). The cli should at least tell you what is going wrong. The next thing is why are you getting that error and that is dependent on the error message. - Craig PS (not relevant to your bug) I've started working on the C consolidator. It caches a lot of things so should be a hell of a lot faster, or at least less load on your database.The main problems I've had is the generic database libraries are buggy. I've tried libdbi and apr-util. -- Craig Small GnuPG:1C1B D893 1418 2AF4 45EE 95CB C76C E5AC 12CA DFA5 http://www.enc.com.au/ csmall at : enc.com.au http://www.debian.org/ Debian GNU/Linux, software should be Free ------------------------------------------------------------------------------ _______________________________________________ jffnms-users mailing list jffnms-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jffnms-users
