Emmanuel Appiah Boateng - PeerSpot reviewer
Network and Security Engineer at a educational organization with 1,001-5,000 employees
Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
BasilJiji - PeerSpot reviewer
System Engineer at a retailer with 10,001+ employees
Real-time alerts have reduced server outage impact and support fast incident response
In the dashboard, if they could show a little more metrics regarding the application and related things, that would be how New Relic could be improved. Currently, there are things showing from the server level and application level, but it can be improved. That is what I felt. Regarding user interface, I do not feel much concern, but for some kind of issues when we are trying to get support from the New Relic team, their SLA seems to be long. They are taking seven to ten working days for resolving some kind of scenario or issue. That is a bit difficult for us. If they could improve the customer support by reducing their SLA within three to five days, if they could remediate everything, that will be so much helpful. When it comes to the customer support part, I felt they need to be a little more improved on that part. The support overall is good, but they can improve. That is the reason I have given it eight out of ten.
