Ntopng vmware appliance9/20/2023 ![]() ![]() We recommend installing Centreon via RPM or via our ISO file. If this is not the case, consider using our turnkey solution (iso installation system in the "Appliances" tab) that lets you install supervision platform very easily. Before downloading Centreon, please validate that you can meet the prerequisites. This is the Centreon web interface, configuration management of demons to monitor resources. Information is clustered per: (Capture) Network Device Flow Host. When using multiple interfaces in the same system, the bandwidth of the PCI bus can easily become a bottleneck.Centreon Web is commonly called Centreon. Part 2: ntopng+Wireshark Monitoring Use Cases Using ntopng. In environments where extremely high throughput through several interfaces is required, especially with gigabit interfaces, PCI bus speed must be taken into account. Remember if you want to use your pfSense installation to protect your wireless network, or segment multiple LAN segments, throughput between interfaces must be taken into account. Server class hardware with PCI-e network adapters. Server class hardware with PCI-e network adapters, or newer desktop hardware with PCI-e network adapters. No less than a modern Intel or AMD CPU clocked at 2.0 GHz. We recommend a modern 1.0 GHz Intel or AMD CPU. We recommend a modern (less than 4 year old) Intel or AMD CPU clocked 500MHz or greater. All of the following numbers also assume no packages are installed. The numbers stated in the following sections can be increased slightly for quality NICs, and decreased (possibly substantially) with low quality NICs. Vendors will begin shipping products pre-installed on virtual machine images to reduce cost and complexity, and the virtualization platforms will relinquish. Above 1Gbps, other factors, and other NIC vendors dominate performance. We therefore strongly recommend purchasing Intel cards, or systems with built-in Intel NICs up to 1Gbps. GitHub ntop / ntopng Public Notifications Fork 607 Star 5.NICs based on Intel chipsets tend to be the best performing and most reliable when used with pfSense software. When using pfSense software to protect your wireless network or segment multiple LAN segments, throughput between interfaces becomes more important than throughput to the WAN interface(s). A quality NIC can substantially increase system throughput. Inexpensive NICs can saturate your CPU with interrupt handling, causing missed packets and your CPU to be the bottleneck. Selection of network cards (NICs) is often the single most important performance factor in your setup. Requirements Specific to Individual Platforms: You may be able to get by with less than the minimum, but with less memory you may start swapping to disk, which will dramatically slow down your system. Note the minimum requirements are not suitable for all environments. The following outlines the minimum hardware requirements for pfSense software version 2.x. PfSense Hardware Requirements and Guidance Snort and ntop are two that should not be installed on a system with less than 1GB RAM. Packages - Some of the packages increase RAM requirements significantly. For large environments requiring state tables with several hundred thousand connections, or millions of connections, ensure adequate RAM is available. For example, a firewall with 1 GB of RAM will default to 100,000 states which when full would use about 100 MB of RAM. The default state table size is calculated based on 10% of the available RAM in the firewall. Large State Tables - State table entries require about 1 KB of RAM each. AES-NI acceleration of IPsec significantly reduces CPU requirements on platforms that support it.Ĭaptive Portal - While the primary concern is typically throughput, environments with hundreds of simultaneous captive portal users (of which there are many) will require slightly more CPU power than recommended above. I believe that having eth1 and eth2 on the same network isnt a wise choice, for instance. So forget ntopng for a second (that is passive) and make sure that the basic networking is ok on your system. The number of connections is much less of a concern than the throughput required. In this configuration all the routing/bridging is implemented by the kernel, and ntopng is inspecting the traffic. Encrypting and decrypting traffic is CPU intensive. VPN - Heavy use of any of the VPN services included in the pfSense software will increase CPU requirements. Most features do not factor into hardware sizing, although a few will have a significant impact on hardware utilization: The following outlines the best practices for choosing the appliance best suitable for your environment. 2.5 Gigabit, and 10 Gigabit SpeedsĤx Intel 2.5 GbE i226 Discrete (unswitched) ![]()
