How Many CPU and Memory Resources Are Occupied by the Agent While It Is Running?

HSS uses lightweight agents, which occupy only a few resources and do not affect your services.

The CPU and memory usage is as follows.

Maximum CPU Usage

A running agent occupies a maximum of 10% of a vCPU. The actual usage depends on your server specifications. For details, see Resource usage of different specifications while the agent is running.

If the CPU usage reaches 10% of a vCPU, the agent will automatically reduce CPU usage, spending more time on scans. This does not affect your services.

The agent is scheduled to scan your servers from 00:00 to 04:00 every day, avoiding your service busy hours.

Peak Memory Usage

A running agent occupies about 150 MB memory.

If the memory usage reaches 200 MB, the agent will be automatically restarted within 5 minutes.
