Nagios XI is being used as a network, server, and database monitoring tool in the Information Technology Department. SMTP settings are available and whenever the server will be down, it will generate an email and inform the server administrator.
  • Network monitoring.
  • Database monitoring.
  • Windows Server monitoring.
  • Cluster Service monitoring.
  • Graphical user interface must be enhanced.
  • More monitoring agents must be included.
Nagios is best suited in an large organization where it is production 24/7, but in SME (small/medium enterprise) you have to pay a lot to the administrator. Instead use some graphical and easy to use tool like IDERA.
  • Minimize downtime.
  • Improved RTO.
  • Improved RPO.
Cost efficiency is the main reason which we opted [for] Nagios as we were previously using IDERA tool with comprehensive database monitoring solutions, but the slow performance we are getting while monitoring the instance of the database.

For in-house infrastructure monitoring and application performance monitoring across the entire organization. Some 1000 hosts, 50+ Applications, various 3rd party integrations. We do both monitoring and logging, also using a single view Fusion product provided by Nagios. We have started using Nagios to collect and store detailed performance information about our infrastructure and ended up developing end-2-end monitoring solutions, talking back to Nagios XI via its API for alerting and reporting purposes.
  • 3rd party integrations via open API.
  • Extremely flexible and configurable long term storage of the very detailed performance information (years of per 1-5 min perf data numbers).
  • Small Nagios XI footprint (very efficient MySQL DB and flat files for perf data), making it powerful tool for thousands of checks and hundreds of reports.
  • Responsive support, willing to provide resolution outside the box and by various means possible.
  • Robust, but visually old interface. Requires a lot of work to become presentable.
  • Small selection of dashlets to construct new views.
  • No MS Azure monitoring ability, nothing for “as service,” very limited Amazon cloud monitoring abilities.
  • Questionable price politics (could make it a lot less for developing markets to actually increase use of the product and R&D budgets).
  • No report designers nor the ability to create new reports. No changes in this area for years.
  • Overall lack of new developments, making this product more and more outdated.
Nagios XI is suitable for inexpensive and very detailed monitoring of the physical hosts and VMs. Both Windows and Linux. This would require configuring 2-3 ways of monitoring for the same set of hosts and some time spent to fine tune the configurations. It may also be used for SQL and Apache front-ends such as Tomcat, Glassfish, etc.
  • Very good ROI.
  • Good results as capacity mgmt tool.
  • Good results as application monitoring tool.
Nagios XI is better supported vs SolarWinds, needs less manual administration work vs Datadog and a lot less expensive for a long as you are willing to compromise on the look and some functionalities. Moreover, SolarWinds database design prevents one from storing any meaningful data for an extended period of time (creating averages of the averages of the averages), where Nagios could be set for keeping years of detailed information without large storage or the overutilized DB engine. In both Datadog and SolarWinds trials we could not get answers to many of our questions, configure working solutions out of the box by using the inline documentation. Nagios XI does not have limitations, offers such as AppOptics impose on the customers (making it very expensive and absolutely not a real life product). Overall, Nagios XI is a great tool, requiring a lot of R&D “yesterday” to make it beat all the competition on all fronts. That is assuming you have an extensive knowledge in the many areas of IT (thus knowing what should be monitored and how to interpret the data).
Only because I never give out 10s.
Nagios support goes above and beyond in helping with issues, workarounds, specific cases and requirements. Tracks customer implementation and history of the most important issues. Can’t complain (except that the team is small and quite probably overworked). Time to resolution could be much improved if only there were more folks to help around.

Nagios XI is helping us to do the monitoring completely automatic. The advance dashboard and admin dashboard are designed so well and are easy to configure as per each user's need. The scheduled managed report help in scaling up the capacity planning of the infrastructure. Nagios XI is providing the complete and comprehensive IT infrastructure monitoring many of our projects, and helps us to deliver the project in faster and more efficient ways.
  • Nagios XI has an exclusive feature of bulk modification of attributes that help in monitoring the same set on monitoring modules on a newly set up environment.
  • It allows you to monitor many network devices, such as switches, routers, servers, and is helping to monitor network performance and track traffic on the network interface.
  • The audit trails feature allows us to scrutinize the modification or setup.
  • The mobile interface is newly developed and needs more development. It should provide more options for the audit log and add more detail for the configuration rollback options.
  • The scheduled report should be included in standard edition.
  • Master Node is configurable on LINUX platform only. We had to hire a Linux administrator
Nagios' ability to chart website ping values over any length of time helps when trying to correlate the data with other network components. Website ping and response times can be used in combination with other data as a great first step when determining whether or not connectivity and performance issues are limited to just the local network.
  • Reduction of at least 10% of false alarms.
  • Increased network traffic by 5%.
I like to be fixed rather than just dislike: it's not user-friendly with almost anything excluding a Windows Operating System. A Linux version, for example, is visibly backward. This does not seem to be a serious issue for most people, but it is still considered a disadvantage. As I do not like the way the dashboards are supposed to be designed, I think it should be easier and take less time. The initial price is reasonable, and for this reason we decided to buy it
Nagios XI support has plans to offer the following features:
  • Access to knowledgeable IT professionals – including support staff and developers.
  • Access to customer-only tutorials, documentation, and content in the Nagios Library.
  • Access to customer-only boards on our support forum for expedited assistance.
  • Access to customer-only email support for fast, confidential assistance.
  • Discounts on future license purchases.
