Requires Redis and MySQL running before setup, plus loading SQL schema files and compiling multiple Go services from source.

In plain English

Falcon+ is an open-source monitoring system designed for tracking the health and performance of servers and services in an organization. Monitoring systems collect data like CPU usage, memory consumption, and error rates from machines, store that data over time, and alert teams when something goes wrong. Falcon+ is an enterprise-oriented option in this category, built for teams running infrastructure at scale. The system is made up of multiple components that run as separate processes: an agent that collects data from individual machines, a transfer component that routes incoming data, a judge that evaluates alert rules, a graph component that stores time-series data, an API server, and several others. All of these can be started and managed through a single command-line binary called open-falcon. The README shows commands for starting all modules at once, checking their status, stopping individual ones, and restarting them. Setup requires Redis and MySQL to be running before you begin. The installation process involves cloning the repository, loading several SQL schema files into MySQL to create the required databases, building the source code using Go, and then running the packaged result. A Docker path is also available and documented in a separate file within the repository. The README includes a note recommending that teams using Kubernetes and microservices consider a newer project called Nightingale instead, which the same community has developed as a cloud-native successor to Falcon+. This suggests Falcon+ is mature but may not be the actively evolving option for modern infrastructure setups. A dashboard is installed separately by following instructions in a companion repository. Grafana can also be connected as an alternative visualization layer through a dedicated plugin.

Copy-paste prompts

Prompt 1

Walk me through setting up Falcon+ from scratch on a Linux server: installing Redis and MySQL, loading the SQL schemas, building the Go source, and starting all modules with the open-falcon binary.

Prompt 2

How do I configure the Falcon+ agent on a monitored server to collect custom application metrics and send alerts to a specific contact when a threshold is exceeded?

Prompt 3

I want to visualize Falcon+ metrics in Grafana instead of the built-in dashboard. What steps do I need to follow to connect Grafana to Falcon+?

Prompt 4

I'm running Kubernetes microservices. The Falcon+ README recommends Nightingale instead, what are the key architectural differences and what does a migration path look like?
