CVM monitoring metrics need to be collected through the CVM monitoring component. Users can automatically install the monitoring component by selecting Cloud Monitor when purchasing machines, or manually install it based on the Monitoring Component Installation Guide.
Cloud Monitor provides the following monitoring metrics for CVM instances:
| Metric/Event ID | Metric/Event Name | Unit | Metric Description |
|---|---|---|---|
| CPUUsage | CPU utilization | % | Real-time CPU utilization during machine operation. |
| BaseCpuUsage | Basic CPU utilization | % | Basic CPU utilization is collected and reported by the host, and data can be viewed without the need to install the monitoring component. Data can still be collected and reported even when the instance is under high load. |
| MemUsed | Memory usage | MB | Amount of memory actually used by the user, excluding the memory occupied by buffers and system cache. |
| MemUsage | Memory utilization | % | Amount of memory actually used by the user, excluding the memory occupied by buffers and system cache. |
| CvmDiskUsage | Disk utilization | % | Disk utilization monitoring. |
| DiskIOAwait | Disk I/O wait | ms | Average wait time per I/O operation for disk partitions. |
| DiskReadtraffic | Disk read traffic | KB/s | Average data read volume from disk to memory per second. |
| DiskWritetraffic | Disk write traffic | KB/s | Average data write volume from memory to disk per second. |
| LanIntraffic | Inbound private network bandwidth | MB/s | Average inbound traffic per second on private NIC. |
| LanOuttraffic | Outbound private network bandwidth | MB/s | Average outbound traffic per second on private NIC. |
| LanInpkg | Number of inbound packets on the private network | Counts/second | Average inbound packet volume per second for private NIC. |
| LanOutpkg | Number of outbound packets on the private network | Counts/second | Average outbound packet volume per second for private NIC. |
| WanIntraffic | Inbound public network bandwidth | MB/s | Average inbound traffic per second on public NIC. |
| WanOuttraffic | Outbound public network bandwidth | MB/s | Average outbound traffic per second on public NIC. |
| WanInpkg | Number of inbound packets on the public network | Counts/second | Average inbound packet volume per second for public network NIC. |
| WanOutpkg | Number of outbound packets on the public network | Counts/second | Average outbound packet volume per second for public network NIC. |
| TcpCurrEstab | Number of TCP connections | Count | Monitoring of TCP connections. |
