How to install collectd and send metrics to Graphite/Statsd
Collectd is a daemon which collects system and application performance metrics periodically and provides mechanisms to store the values in a variety of ways, in our case sending to Graphite. Collectd gathers metrics from various sources, e.g. the operating system, applications, log files and external devices, and stores this information or makes it available over the network. Those statistics can be used to monitor systems, find performance bottlenecks (i.e. performance analysis) and predict future system load (i.e. capacity planning). Or if you just want pretty graphs of your private server and are fed up with some homegrown solution you’re at the right place, too.

How to Setup Central Logging Server with Rsyslog in Ubuntu 20.04 – Citizix
Rsyslog is an open-source software utility used on UNIX and Unix-like computer systems for forwarding log messages in an IP network. It is an open-source utility for log processing. It permits the logging of data from different types of systems in a central repository. Rsyslog is a Syslog protocol with more extensions, features, and benefits.
Rsyslog can deliver over one million messages per second to local destinations when limited processing is applied making it so powerful. By default, Linux uses the syslog daemon to record logs about how the system is running and then putting these logs into a central repository in: /var/log where we can examine and investigate them.
In simple terms of meaning everything from kernel events to user actions is logged by Linux, allowing you to see al most any action performed on your pc or servers. -
