Last time we focused on the agent side but now we are going to understand on another key component: the controller.. The controller acts as a Route Reflector, announcing… Read more →
We know that all software components and services generate log files. These log files are vital in troubleshooting and debugging problems. If the log files are not managed properly then it can be extremely difficult to get a good look into them. Although system administrators cannot control the generation of logs, they can achieve some level of log management by… Read more →
