The most common cause is that ntop is seeing the same traffic twice (for example you have on multiple NICs, one monitoring inside the firewall and one outside - traffic outside your network is seen twice).
This can create two HostTraffic entries that are sufficiently similar to point at the same .rrd file (but not quite identical enough to get merged together) (typically the MAC address gets changed by an intervening switch or router). Check the -O | --no-mac switch and read the FAQ on it. -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of n d Sent: Friday, June 30, 2006 10:52 AM To: [email protected] Subject: [Ntop] RRD Warnings Fri Jun 30 11:39:10 2006 **WARNING** RRD: rrd_update(/usr/local/var/ntop/rrd/interfaces/hme0/matrix/10.1.1.125/10.1.1. 2/bytes.rrd) error: illegal attempt to update using time 1151681950 when last update time is 1151681950 (minimum one second step) Fri Jun 30 11:39:10 2006 **WARNING** RRD: rrd_update(/usr/local/var/ntop/rrd/interfaces/hme0/matrix/10.1.1.125/10.1.1. 4/pkts.rrd) error: illegal attempt to update using time 1151681950 when last update time is 1151681950 (minimum one second step) Fri Jun 30 11:39:10 2006 **WARNING** RRD: rrd_update(/usr/local/var/ntop/rrd/interfaces/hme0/matrix/10.1.1.125/10.1.1. 4/bytes.rrd) error: illegal attempt to update using time 1151681950 when last update time is 1151681950 (minimum one second step) Fri Jun 30 11:39:10 2006 **WARNING** RRD: rrd_update(/usr/local/var/ntop/rrd/interfaces/hme0/matrix/10.1.1.125/10.1.1. 5/pkts.rrd) error: illegal attempt to update using time 1151681950 when last update time is 1151681950 (minimum one second step) Fri Jun 30 11:39:10 2006 **WARNING** RRD: rrd_update(/usr/local/var/ntop/rrd/interfaces/hme0/matrix/10.1.1.125/10.1.1. 5/bytes.rrd) error: illegal attempt to update using time 1151681950 when last update time is 1151681950 (minimum one second step) Nicholas Donato 919.961.1280 "There is nothing as permanant as change." -Heraclitus 540-480 B.C. _______________________________________________ Ntop mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop _______________________________________________ Ntop mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop
