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.
Note
The agent is scheduled to scan your servers from 00:00 to 04:00 a.m. local server time every day. It does not affect the normal running of the server system.
Peak Memory Usage¶
A running agent occupies about 500 MB memory. If the agent memory usage exceeds the maximum memory limit 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.
vCPUs | Max. CPU Usage of Agent | Max. Memory Usage |
|---|---|---|
1 vCPU | 20% | 500 MB |
2 vCPUs | 10% | 500 MB |
4 vCPUs | 5% | 500 MB |
8 vCPUs | 2.5% | 500 MB |
12 vCPUs | About 1.67% | 500 MB |
16 vCPUs | About 1.25% | 500 MB |
24 vCPUs | About 0.84% | 500 MB |
32 vCPUs | About 0.63% | 500 MB |
48 vCPUs | About 0.42% | 500 MB |
60 vCPUs | About 0.34% | 500 MB |
64 vCPUs | About 0.32% | 500 MB |
