Pros

“The pricing structure can also get steep quickly as your host count scales up.”

Drew L.

SR SYS Admin

“Nagios XI can be quite complex to set up the first time you use it.”

Yohan S.

Engineer

“Nagios XI was easy to setup (from the tools we tested), although it has many plugins you can always and easily create your own plugin (anything that is measurable), it has good alerting system when it comes to emails, seems like the GUI/UX could have been more modern but overall experience is very good.”

Gil B.

DevOps

Pros

“It has been very useful for monitoring critical business applications, reducing downtime, and improving overall operational efficiency. Although the initial setup and advanced customization can sometimes be complex, the platform offers strong monitoring capabilities at a cost-effective price compared to many other enterprise APM solutions.”

Rahul R.

Tool Administrator

“It provides comprehensive monitoring, proactive alerting, and valuable performance insights that help maintain application availability and quickly resolve issues.”

Mohd A.

Assistant manager

“Integration between OPM and APM still feels clunky. If more things were shared between the two, such as notification profiles, assets, dependencies, etc. were shared, setting up a large org would be a lot easier”

Travis R.

System Operations Engineer

Cons

“The GUI doesn't seem to be most updated and some of the features are hard to find (UX issue)”

Gil B.

DevOps

“Certain features doesn't help you get down to the root-cause of the issues and investigation has to be done outside the tool.”

VINAYAK S.

AGM

Cons

“Limited Cloud-Native Monitoring Depth While it supports AWS, Azure, and GCP, it lacks the deep, contextual cloud-native observability you get from tools like Datadog or Prometheus/Grafana stacks.”

kabelo m.

security analyst

“The alerting system produces many false positives, especially when it notices that certain services or hosts are down during the nights reserved for routine maintenance tasks.”

Nermin M.

Data Engineer

“At some time the system may take some time to update some screens, for example the dashboard may take some time to refresh during peak usage. If the latency is short it can hamper decision-making whenever decisions are most urgent.”
