Hello list, This is my feedbacks on Ntop.
1) - It would be nice if we can have an option into configure to enable or disable XMLDump, by defaut if libxml2, dome, and very OLD glib1 are not available, then the XML feature is not functional, that's correct but I don't understand why "libxmldumpPlugin" and "xmldumpPlugin.so" are still compilled and installed!! Therefore having an option to enable or disable this feature could be a good addition to the source, also why you still use glib version 1.x? 2) - Running Ntop for home user or small company using Hub work fine because they have not lot of trafics on their network and Ntop work nice on this environement but when we talk about medium or large entreprises using switches (Cisco, FoundryNetwork), then Ntop become a problem. For Ntop to work, we have to use additional switch features like Netflow for Ntop to see the trafic or SPAN if we don't have US 3000$ to buy a Netflow card. In both way activating Netflow or SPAN will generate lot of trafics on the server (also on the switch for SPAN) where Ntop is running and even with an Intel Pro 1000 Ethernet Adapters supporting Jumbo Frame, NAPI, etc, the server and Ntop are not able to handle the load. Ntop consume 80% of all CPU resources and all 3GB of RAM + 1GB of swap in a minute. Since the kernel still need to manage other process, it will automaticaly kill the process causing the problem by consuming all resources (yes Ntop). So which server should I have to run it? A 4 Xeon processors hypertheading with 50GB of RAM on a RAID SCSI system? Ok there is a PF_RING solution that ONLY work with old libpcap version and old Linux Kernel with old GCC version too, so when you use a new Linux system to be update and bug fix, you cannot use this solution and even applying this solution with old software version doesn't fix the above problem. Yes ntop is a great software and I like it, but I'm affraid to explain all of the above in the entreprise when I've to deploy it.
