Red Hat Memory Analyzer visualizes memory usage on your system based on information captured by the SAR utility. In the dynamic chart, RAM shows the percentage of used memory, cache, buffer and free memory while SWAP shows the percentage of used swap.
It provides two additional functions.
- Checks memory configuration in sysctl.conf file and shows you the parameters whose current values are different from their default values. This can help you to decide whether the non-default values were assigned purposefully or just by mistakes.
- Shows HugePage information. You need to upload the meminfo file from your system.
