ScyllaDBTop: real-time monitoring for ScyllaDB in the terminal

ScyllaDBTop is a diagnostic tool designed to provide real-time monitoring of ScyllaDB nodes directly from the terminal by connecting to the collectd data gathering service, allowing users to view a variety of metrics without the need for complex monitoring setups. This lightweight program requires no additional dependencies beyond the standard Linux distribution and can be configured to display both ScyllaDB-specific and general metrics by leveraging collectd plugins. ScyllaDBTop, included in the ScyllaDB package and preinstalled on its Amazon EC2 AMI, is not meant to replace comprehensive monitoring solutions like ScyllaDB Monitoring or Grafana but rather serves as a complementary tool for quick and straightforward node diagnostics. The program must be run on the same host as collectd, which can be configured to use various plugins to monitor network errors, disk I/O, and more, enhancing its flexibility and utility in managing and understanding system performance.
