What is Collectd?
collectd is an open source daemon that collects system performance statistics periodically and provides methods to store the values in a variety of ways. It supports collecting data from a broad range of subsystems like operating system metrics, logging daemons, network load and more.
Some key features of collectd include:
- Written in C for performance
- Modular plug-in design to support many different data sources
- Built-in server to create graphs and analyze statistics through a web interface
- Various storage plug-ins for RRD, CSV, MongoDB, etc.
- Client/server architecture for centralized statistics collection
- Security features like encryption and authentication
collectd requires very little resources so it can run well on everything from small IoT devices to enterprise servers. The statistics it collects can be used to monitor systems, detect issues and optimize performance. Common use cases are IT infrastructure monitoring, network monitoring and application performance management.
