Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

Nagios XI's plans are primarily based on the Node-count of the license. A Node is anything with an IP address or Fully Qualified Domain Name (FQDN) that you would like to monitor (switches, routers, firewalls, workstations, and other network devices). There are no restrictions on the number of Services you can monitor. While paid licenses of Nagios XI do not contain any software-imposed limitations, we have found that systems performing more than 15,000-20,000 checks in a 5-minute interval should consider following our Server Considerations Guide to ensure the best performance on your installation. Nagios XI also offers an Enterprise add-on which enhances the software's capabilities. This addition allows users to schedule reports, project future values with capacity planning, and much more. Refer to our Enterprise documentation or contact a Nagios sales representative to learn more about the capabilities of the Enterprise-level license. With the purchase of a Nagios XI license, you receive access to Premium Features as part of your Maintenance & Support benefits for the first year. After the first year, renewal of your Maintenance & Support plan is required to maintain this feature set. This includes features such as Single-Sign On (SSO) via MS Azure AD, the Nagios Mod-Gearman user interface, and a collection of premium wizards! To learn more and see the full list of features, you can visit our article on Premium Features or contact Nagios sales.
