    This article is out of date for Pricing. XI is much more expensive. RIght now it’s $1,995 for up to 100 hosts, $2,995 for 100-200 hosts and a whoping $4,995 for unlimited. A far cry from the previous $1,295 for unlimited.

    Yes, agreed, the current pricing makes it far less cost effective to go for Nagios XI.

    how u are saying $1,295 nagios xi price ?
    I checked on website its about $6000.

    Exactly, and even while you still may consider the new price affordable for your organization this does not speak well of the company behind Nagios products. Why?

    Not only they doubled in price but they limited it to 100 hosts !!! And now in their Enterprise edition they force the annual plan. Its not an optional maintenance, but it seems its required.

    So to any prospect buyer (like me) I will not purchase the product, because for all I care tomorrow they change their 100 nodes to 100 sensors instead !!! It seems this is where they are going. First 1 price per monitoring instance or installation. Then per monitored end machines but unlimited services on each and I bet in the future per sensor.

    I don’t understand why this software companies license their products as if its they who are paying for the monitoring. They don’t. If you install Nagios on a server, it can only monitor a fixed numbers of things before you run out of resources (which you are paying) so its makes no sense how the monitoring software company want to rip off their customers. The license should be per INSTALLED machine. So if you have 2 in a fail over, they charge 2. Regardless of how many end devices or things you monitor. Otherwise just use some cloud monitoring service where everything is included and you don’t bother with anything.

    This models sucks for on premise software. They get some customers with cheap or free beta products, then start to raise prices. I really wanted to buy several of their products…I guess I will stick to my current solution (which is paid and expensive but was looking into Nagios to save some bucks)
