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.

I use IBM Instana for real-time application performance monitoring across our applications and infrastructure. It helps me track service dependencies, analyze distributed traces, identify performance bottlenecks, and investigate incidents more quickly. What I like most about IBM Instana is the level of automatic visibility it provides with relatively little manual configuration. The automatic discovery of applications, services, infrastructure, and their dependencies is especially valuable, as it quickly builds a clear picture of how the environment is connected. I also appreciate the combination of real-time monitoring, distributed tracing, and infrastructure metrics in one interface. This makes it easier to move from a high-level alert to the specific service, request, or infrastructure component causing the issue. The visual service maps and detailed transaction traces stand out because they make complex microservices environments much easier to understand and troubleshoot. The initial setup was very easy, taking just one day. Review collected by and hosted on G2.com.
