Fping (open source) VS Netactview

fping is a program to send ICMP echo probes to network hosts, similar to ping, but much better performing when pinging multiple hosts.

Speed
Fping is designed to send out multiple ICMP Echo Requests in parallel, allowing it to quickly scan large numbers of hosts compared to traditional ping commands.
Scripting Friendly
Fping is suitable for use in shell scripts due to its output format, making it useful for automated network monitoring and management tasks.
IPv4 and IPv6 Support
Fping supports both IPv4 and IPv6, providing flexibility for various network environments.
Customizable Options
It offers a wide range of options for setting the number of pings, intervals, and timing, allowing users to tailor the tool to suit specific needs.
Resource Efficiency
Fping consumes fewer system resources compared to some GUI-based network tools, making it ideal for running on servers and low-power devices.

Command-Line Interface Only
Fping does not have a graphical user interface, which may make it less accessible to users who are not familiar with command-line operations.
Advanced Configuration Complexity
While it is highly configurable, the range of options and parameters can be overwhelming for new users who may not have a deep understanding of networking.
Limited To Echo Requests
Fping is designed specifically for ICMP Echo Requests, limiting its usefulness for scenarios that require more in-depth network diagnostics.
Lack of Built-In Analysis
Unlike some more comprehensive network monitoring tools, Fping does not include features for detailed analysis and visualization of network data.
Potential Security Restrictions
Some networks may have security policies that restrict the use of ICMP packets, which could limit Fping's effectiveness or even prevent it from functioning.
