Here are just a few sample of what they have to say...

What People Are Saying about Nagios

"Hi Shamas, BTW Nagios proved its worth last night; part of our infrastructure outside of the main ‘production’ data center got hit by a power spike last night; which meant that one of the development teams in Sweden no longer had a server to build on; which meant a possible 12 hour delay before someone even noticed. Nagios noticed within a minute and we could get someone over to the building to flip a few circuit breakers. Then this morning part of one of our VM clusters died during a sw upgrade. We noticed even before IT did – and now I’m working through the list of impacted systems to verify that they all came back cleanly. All in all a good day." - Nagios XI Customer

"Thanks Andy. You have been great help. After working and creating so many tickets, I can say NAGIOS SUPPORT IS AWESOME. " - Nagios XI Customer

"Really loving the very active nature of the support forum. A real blessing from God." - Nagios XI Customer

"Thumbs up to the team at Nagios. Best support I've encountered in 20 years of being in the IT game." - Nagios XI Customer

"This ticket can be closed. I'd like to point out that Nagios support is the best I've encountered! And, I've been doing IT for a dozen years." - Nagios XI Customer

"I know that this forum is for reporting issues, but I just wanted to take the time to say thanks for the phenomenal support and work you guys do. I was REALLY concerned when I was told that nagios support is forum based, but you guys have always responded to my issues with awesome results for me. Thanks you guys and make your boss get you a round of <insert non-alcoholic beverage of choice here>, you deserve it." - Nagios XI Customer

"I am happy to say I am back on track for the proof of concept. I initially started out with the install of R2.0 and discovered an install bug. This prompted a fix by your team and the release of R2.1. When I went to install 2.1, I most likely did not have a clean system. The last response of Ludmil made me connect the dots of not having a clean install. I proceeded to remove NagiosXI from the server as well as cleaning the data out of the DB's. I was able to run the install and configure the system without issues. I am seeing all of the hosts in the dashboard. Thanks again for your help and the Nagios support team. I am excited to start working with XI and presenting a final product to our team for production use. The quick response by your team also demonstrated the type of support we can expect as an enterprise customer. That also helps a lot." - Nagios XI Customer

"Thank you everyone, especially Mike from Sales and Nick Scott, for your help in getting our XI monitoring system back up and running. About an hour before our big demonstration all of our pre-configured Hosts and Services disappeared. Wow, we were in a panic mode to say the least. Mike recognized the urgency and contacted Nick from the Support team. Nick went above and beyond, and brought our system back from the “dead”. We truly appreciate your product but it is moment like this that we valued and it shows that you care. " - Nagios XI Customer
