Checking the Redis Server's health status is important in troubleshooting issues. By monitoring the metrics and statistics information, we can often see what has happened or is happening on the server and may deduce the root cause of the issues. In this recipe, we will introduce a couple of Redis Server metrics or statistics that you should keep an eye on when troubleshooting issues.
