free software tool for network monitoring. It allows to monitor and record the status of several services in a network of computers, servers or hardware of the network itself. It is available under the Free GPL software license. Among its features include, Check the availability and response level of various services such as web services or mail, It allows to obtain statistics how to load a CPU, disk usage, network bandwidth, It allows to monitor services through protocols such as SNMP, TCP, ICMP or SSH and telnet.
It is very complex to use,The user manuals are very extensive which makes many users desist from using it.
By way of conclusion, if you are looking for a new network monitoring tool, either for an installation that does not have a monitoring system or for one that already has a system that you want to migrate, I recommend you evaluate Zabbix
Obviously I can not recommend one of these tools for it would have to know the installation and its features, but from my point of view, with these 3 options you will surely cover your monitoring of networks, and servers.
What did you think of my experience? I hope I can help you in your decision process. Do not hesitate to ask me any questions you have.
I use zabbix to monitor the infrastructure of our company (which is only 6 servers + all the network material). I have had zabbix for more than two years and it works very well. I like the fact that it is all in one application and does not require the installation of tons of plugins. The interface does not win any design awards, but it comes surprisingly well in terms of functionality. I've had some intermittent hardware problems on our servers in the past and having a lot of historical data in zabbix definitely helped a lot in narrowing them.
Some versions seemed to have stability problems and crashed from time to time, but monit took care of that.
I recommend putting zabbix in a separate box (and some hardware of the unarmed server of 3-4 years will work quite well) The application itself is not very heavy, but puts a significant strain on the database (mysql in my case) Save all Historical data is not cheap.
