~85 MB

~875 MB including plugin updates

Note: Under certain conditions, disk usage can spike up to 3 GB or more.

~50 MB RAM

Note: In Linux environments, the Hugepagesize value plays a significant role in the usage shown by the systemctl status nessusagent command. The shown usage not only includes the agent processes' RAM consumption but also any cached data that would be stored on disk if the system experiences memory pressure.

For example, x86-64-based Linux systems typically exhibit a total usage ranging from 200 MB to 600 MB with the default Hugepagesize value of 2048 kB. ARM64-based Linux systems with a larger Hugepagesize value show correspondingly high memory usage (for example, the usage shows as multiple gigabytes with a default Hugepagesize of 512 M).
