Monitor

We provide monitoring services for your host, network and other resources, allowing you to keep track of the system operation status and resource usage at any time, which is convenient for locating and analyzing problems.

Host monitoring items by default include CPU utilization rate, disk read/write, and network interface inbound/outbound bandwidth and packet volume. If you install our monitoring agent, you can also monitor more metrics such as memory utilization rate and disk space utilization rate.
