Nope, Ken, I really meant debug - as in the #define in the source. I'll bet it's the usual culprit - permissions... debug should show the error messages, although most errors should have already appeared in the log.
I'd focus on rrdPlugin.c first. Nothing in mainline code is going to matter. The enumeration code - such that it is - is in initDevices(), but it just calls uses what you give on the -i parameter or calls pcap_findalldevs. I highly doubt that's got major problems. -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kenneth Porter Sent: Friday, May 27, 2005 9:47 PM To: [email protected] Subject: RE: [Ntop] rrd not updating --On Friday, May 27, 2005 7:58 AM -0500 Burton Strauss <[EMAIL PROTECTED]> wrote: > I used to see that.

I'm assuming you mean tracing. I set it to 7 but don't see anything reported from the RRD plugin after it says that it's started. > (2) Check the mtime (modification times) of the .rrd files.

I tried renaming the old rrd file and creating a new empty one. The plugin recreates the 3 subdirectories at startup, but it doesn't create the "eth1" interface subdirectory, and complains of its absence when I try to view data. Seems like data collection just mysteriously won't start. My system has eth0 shut down. Could that be an issue? (Just thinking that the collector might fall over while enumerating interfaces.) I'll poke through the sources and see what I can see. _______________________________________________ Ntop mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop _______________________________________________ Ntop mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop
