    Nagios Alternatives

    Nagios is a monitoring system that helps organizations identify and resolve IT infrastructure issues. If you need to monitor a complex web of services internally, this is a hugely helpful tool that can save a huge amount of time in identifying and resolving potential problems.

    Nagios is free and available on Linux, but it is not open source. This is especially important to consider when dealing with highly confidential and sensitive infrastructure. In this case, the added transparency and potential for modularity that open source Nagios alternatives can provide could very well be preferred.

    Nagios is mainly a Network Monitor but alternatives to it may also be Uptime Monitor Services or Website Monitors. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of Nagios.

      The guided SaaS setup has extremely useful. I was able to get my 18 servers monitored in less than 30 min - and all the settings were preset at reasonable values.
