The absolute standout for me is how effortlessly I can spin up custom EXE sensors that pull live Modbus data straight from our legacy PLCs on the factory floor and correlate it with power draw on individual CNC machines. No other tool I’ve tried lets me do that without fighting through three layers of middleware or writing a full-blown agent. Last quarter I had one sensor flagging a 12% spike in vibration on a milling station at 2 a.m.—turned out to be a bearing starting to go. Fixed it during the next shift window instead of losing half a day of production. Review collected by and hosted on G2.com.

I like the way checkmk is configured, especially compared to 10 years ago. Today we have a nice structure with folders, contact groups, server groups, and corresponding rules. I also like the agents of checkmk because they don't perform evaluations, which is a huge advantage in database monitoring when the server is under load. Review collected by and hosted on G2.com.
Pandora FMS is the most flexible monitoring software in the market.
Also listed in Observability Software, Server Monitoring, Log Monitoring, Cloud Infrastructure Monitoring, Application Performance Monitoring (APM)
We have been using Pandora for a long time and we have always liked the support and the way the tool processes data.
For us it was and is very important that reports can be sent and that there is a clear way to display the data on the screen so that a technician and even non-technical personnel can see it.
We monitor SQL tasks, Veeam backups, temperatures, disk array status, raid, equipment through SNMP... everything we can think of.
Nowadays even more things when we use AI.
The performance of the tool is quite good, never saturating the server where it is installed. Furthermore, the price is adjusted and valid for our needs. Review collected by and hosted on G2.com.

enterprise open source monitoring solution for networks and applications

I have been using Zabbix for monitoring servers, network devices, VMware infrastructure, and services, and overall it is a powerful open-source monitoring solution for enterprise environments.
What I like most is its flexibility and wide monitoring support. It supports Linux servers, Windows systems, SNMP devices, VMware, cloud services, custom scripts, and application monitoring in a single platform. The dashboard and alerting system are highly customizable, and the proxy architecture helps in monitoring remote locations efficiently.
The template-based monitoring saves a lot of time, especially for infrastructure monitoring. Integration support for AWS, VMware, databases, APIs, and notification platforms like Slack and Telegram is also very useful.
One downside is that the initial setup and trigger configuration can be complex for beginners. The UI feels slightly outdated in some areas, and fine-tuning alerts requires experience to avoid excessive notifications. Many users in the community also mention the learning curve and configuration complexity.
Overall, Zabbix is an excellent monitoring tool for system administrators and enterprises looking for a scalable and cost-effective monitoring solution with advanced customization capabilities. Review collected by and hosted on G2.com.
