Logging System Utilization Data on a Schedule with nmon
In this hands-on lab, we are going to use nmon to capture server performance statistics. The first step will be to connect to the server, install nmon, and confirm it launches. After the install has completed, we will create a log directory for nmon logging and make sure that we can write to the directory. Next, we will test the `nmon` logging command to verify it collects data and can write that data to the directory. The last step will be to create a cronjob to run the `nmon` command once a week at a specific time.
