If you are talking about the "Global TCP/UDP Protocol Distribution", "Historical View" on the trafficStats.html page it is built by scanning (look in plugins/rrdPlugin.c for graphSummary(), case 4) based on the .rrd files ntop finds in the interface directory which are not Flows and have IP_ in their names, then yes...
Deleting the .rrd file (obviously) removes any information. ntop will simply recreate the file if it finds data, but there won't be any history in the rings. And if it doesn't find the file, it won't show up in the graph. Since those IP_xxxx files are based on the protocols you are monitoring, this can be a good thing to do if you drastically change the protocols you are monitoring. E.g.: 01:03:31 tigger [Linux] user=ntop pwd=/devel/ntop/rrd/interfaces/eth2 $ ls -lt | grep -v Flow | grep IP_ -rw-r--r-- 1 ntop users 62940 Sep 2 01:02 IP_SNMPBytes.rrd -rw-r--r-- 1 ntop users 62940 Sep 2 01:02 IP_SSHBytes.rrd -rw-r--r-- 1 ntop users 62940 Sep 2 01:02 IP_DNSBytes.rrd ... -rw-r--r-- 1 ntop users 62940 Aug 17 11:01 IP_NFS_AFSBytes.rrd -rw-r--r-- 1 root root 35292 Aug 17 11:01 IP_VoIPBytes.rrd -rw-r--r-- 1 root root 35292 May 25 12:03 IP_TelnetBytes.rrd The ones that haven't been updated in MONTHS are good candidates to nuke, just to cleanup the graph. -----Burton PS: Just for reference, this kind of question is fine to ask on ntop (user list). Answers in ntop-dev tends to get more codish... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kurt Swank Sent: Thursday, September 01, 2005 8:44 PM To: [email protected] Subject: [Ntop-dev] RRD/Historical information How can I clear out the data in the RRD database that is used for the historical graphs? It looks like the legends in the historical graphs are coming from the ntop.conf file that was used when I initially started ntop I have since removed many of these protocols, but historical graph still show these old protocols. If I clear the RRD database can I also get rid of these old labels? _______________________________________________ Ntop-dev mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop-dev _______________________________________________ Ntop-dev mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop-dev
