Read the FAQ: Q1(a). Can I store data in a SQL database? Q1(b). When ntop stops I lose all my data. Why? Q1(c). Why doesn't the -S option work?
A. ntop used to optionally store some data in a SQL database. The code was broken, difficult to maintain, etc. and was removed. A LONG TIME AGO. If you are reading about this in 'some' documentation - update. Current ntop is 3.1, which is the only version we support. There are scripts that various users have offered to take the data dump and insert it into a SQL database. Search the back traffic on the mailing list for them. Yes, ntop uses memory based structures to hold usage data and they are lost when you reset or restart ntop. Persistent storage is in the RRD databases - there's a paper @ SourceForge that explains them. There was another option for some persistence - it was -S - look down about 5K lines in this FAQ for an article about it, "What was the -S option?". What part of "Yes, ntop uses memory based structures to hold usage data and they are lost when you reset or restart ntop." can I make any clearer??? -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of nicola mondinelli Sent: Friday, May 27, 2005 4:42 AM To: [email protected] Subject: Re: [Ntop] persistent data storage on ntop I had read the FAQ, l know the property of rrd, but pratically, by the command line, how can i tell to ntop daemon when it start to load the old data from rdd? in my case i use thoose flags ""-u ntop -P /var/lib/ntop" My aim is to have ntop start from the point when it crashed, or stopped. When i read the data from the html server from the port 3000 i wish to read all data inherent the period from ntop install on, not only from the last run. Thanks in advance.
