Monitoring of hosts on Windows is supported, as well as network equipment using SNMP protocols. Icinga can also generate reports on the collected data, the data can be presented in the form of graphs using external add-ons. Message notifications can be viewed in the web interface, or you can receive them by email or any other convenient messenger. Monitoring remote hosts requires the installation of an agent on a remote server.

Both products are treated as source code distributed under the GPL license. Nagios is written in C and Perl, MySQL, Oracle RDBMS, and PostgreSQL can be used as a DBMS. Nagios has a web interface, and in Icinga 2 it has been significantly redesigned on the remote side. Nagios and Icinga come standard with a large number of add-ons, most of which are not found on any Linux server.
Plugins for Nagios and Icinga can be a regular bash script that performs some kind of check and, depending on the result, returns one of the possible values: Nagios and its fork Icinga allow you to monitor the status of services through the SMTP, SNMP, POP3, HTTP, ICMP, and NTP protocols, it is also possible to monitor the status of hosts and system resources. Network monitoring tools, unlike system systems, allow you to monitor almost the entire server environment, from detecting the availability of a host for the ICMP protocol to monitoring the status of a RAID array, and ending with messages in the publication of the protocol. Based on the observation of the creation of products, and on the server agents who are the holders of communication with the server. Typically, network monitoring tools for remote monitoring. There is an alternative netstat called ss. The netstat utility is detected, so lsof is recommended, but many system administrators still prefer Republican netstat because of its simplicity and visibility. Also, lsof can display a list of files, and processing protocol. l sof has a little more functionality, it can also display a list of network connections, as well as test the process using this connection. Netstat displays a list of connections and their status. The interface allows you to easily switch between blocks of information. The utility requires an increase in consumption, displays a list of running processes, disk space used, system resource usage, and displays initial resource usage graphs. These utilities are used in functionality with top similar ones, however, they do not display a list of processes, therefore they are often used to assess the load on system resources, most often to analyze the load on the server disk subsystem.
