How Many CPU and Memory Resources Are Occupied by the Agent When It Performs Scans?

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 20% 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 exceeds 20% of a vCPU, the agent will automatically reduce CPU usage, spending more time on scans. This does not affect your services. If the CPU usage exceeds 25% of a vCPU, the agent will be automatically restarted.

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 500 MB memory.

If the memory usage reaches 500 MB, the agent will be automatically restarted within 5 minutes.

Resource Usage of Different Specifications While the Agent Is Running

The following table describes the CPU and memory usage of different specifications when the agent is running.

**Table 1** Resource usage of the agent
vCPUs	Max. CPU Usage of Agent	Max. Memory Usage
1 vCPU	20%	500MB
2 vCPUs	10%	500MB
4 vCPUs	5%	500MB
8 vCPUs	2.5%	500MB
12 vCPUs	About 1.67%	500MB
16 vCPUs	About 1.25%	500MB
24 vCPUs	About 0.84%	500MB
32 vCPUs	About 0.63%	500MB
48 vCPUs	About 0.42%	500MB
60 vCPUs	About 0.34%	500MB
64 vCPUs	About 0.32%	500MB
