Prometheus

We have multiple services offered to users and actively planning to integrate all of them under a single domain. All of them will be accessible only after one acquires a license with a subscription. The problem is this individual system is developed using various technologies. We needed a central system to monitor health, uptime, and resource consumption. Prometheus was a worthy contender, along with Apache Cassandra. We embedded it in a PHP app using a third-party library. Using API & graphana, we built a dashboard with only needed metrics. it was near real-time, and I would recommend it to anyone who is purely looking for monitoring only. But it was missing some API calls, so if you're charging someone based on usage of your API, I'd say please look for another service. Apart from this, promotion is a really capable language. Setup is not that easy if you're a newbie. We can't complain much because it didn't cost us a dime as it is open source. Also, it's light on hardware and does not bring memory munching processes. We also use it to monitor some PHP-level queue jobs, and it registers each queue execution perfectly.

We are using Prometheus as a monitoring tool in our organization; it helps to track multiple applications and diagnose performance issues and bugs. Prometheus also keeps the system issues and keep application out of risk. Also, it is open source, so many tutorials and documentations are available on the internet. I personally found it very easy to use. all the data metrics are represented in a visual format, so it does a great job with visualization!

My company had several different products to monitor and alert on all aspects of IT. We began using Prometheus to consolidate all the monitoring and alerting products at the best possible cost (free). We also use Prometheus metrics to visualize the data in Grafana which helps get a better picture of our environment.

We use Prometheus to automatically collect and monitor metrics for production Cassandra clusters that we manage for our customers. Metrics like reading latency, write latency, and disk space are used. We then use Grafana to visualize the results. This combination works flawlessly and can be used for monitoring other systems. I do recommend Prometheus as a simple and easy-to-use monitoring solution.

My experience of using Prometheus is based on requirements to monitor and control our server's infrastructure. We have to monitor a lot of parameters in our data center environment (CPU / vCPU utilization, RAID status, network performance and etc.) and Prometheus is exactly what we need - it has a good list of exporters (haproxy_exporter, node_exporter, memcached_exporter and more) that gives us a perfect tool for all-aspects monitoring + YAML-like configuration. Moreover, it has a simple integration with visualization applications (Grafana in our case).
