PRTG's most useful network services include packet inspection, analyzing and storing statistical data into the database, viewing the network map in real time (you can also get historical information about network behavior), collecting technical parameters about devices connected to the network, as well as analyzing the degree of load on network equipment. This software can be used not only to scan devices that are currently connected to the local network, but also serve as an excellent assistant in detecting network attacks. It’s not free (unless you count its 30-day trial period). This PRTG software component, compatible with Windows devices, is designed for network monitoring. You can use either a demo version (which, based on our experience, has an insufficient set of features), or a full license (by paying £200 for each year). All the reports that are generated by analyzing the event log can be presented in the form of diagrams and graphs, clearly demonstrating the vulnerable aspects of the network. You can also obtain information about the technical specifications of all equipment currently connected to the network. Thanks to its well-designed user interface, this software provides sysadmins with a ton of configuration options, from IP ranges for auto-discovery to SNMP protocol settings needed to start collecting network information.
This solution integrates with hardware from Cisco, Windows, Linux, HP, Juniper, Dell, FreeBSD, Brocade, Netscaler, NetApp, and other vendors. Observium is an application that operates using the SNMP protocol and allows not only to examine the state of a network of any scale in real time, but also to analyze its performance.
If you have a small network, then you won’t even need to buy a license: the program will work in free mode. All network activity will be monitored in the activity log and special reports. Each chain element can be edited at any time and will immediately apply to all devices assigned to the scenario. You can use it to organize monitoring schemes of virtually any complexity in order to accurately identify problems and malfunctions, as well as automate the process of eliminating them.Ī scenario is a kind of a workflow based on a sensor, and from it you can construct logic chains, which will, depending on the success of a check, generate different notifications and actions aimed at addressing the problems. The main feature here is the scenario builder, which allows to escape from configuring just primitive checks, that don’t take certain circumstances of device operation into account. Network Olympus operates as a service and has a web-based interface, which makes for greater flexibility and convenience.
