The Hardware > Daily tab provides overview statistics about the following hardware components of the last 24 hours:
- CPU Usage
- Memory/Swap Usage
- Partition Usage
CPU Usage: The histogram displays the current processor utilization in percent.
Memory/Swap Usage: The utilization of memory and swap in percent. The swap usage heavily depends on your system configuration. The activation of system services such as Intrusion Prevention or the proxy servers will result in a higher memory usage. If the system runs out of free memory, it will begin to use swap space, which decreases the overall performance of the system. The used swap space should be as low as possible. To achieve that, increase the total amount of memory available to your system.
Partition Usage: The utilization of selected partitions in percent. All charts show three graphs, each representing one hard disk drive partition:
- Root: The root partition is the partition where the root directory of Sophos UTM is located. In addition, this partition stores update packages and backups.
- Log: The log partition is the partition where log files and reporting data is stored. If you run out of space on this partition, please adjust your settings under Logging & Reporting > Log Settings > Local Logging.
- Storage: The storage partition is the partition where proxy services store their data, for example images for the Web Filter, messages for the SMTP proxy, quarantined mails and the like. In addition, the database, temporary data, and configuration files are located there.
