Huawei Cloud EVS Disk

Collect Huawei Cloud EVS disk metric data

Configuration

Install Func

Recommended to activate Guance Integration - Extensions - DataFlux Func (Automata): All prerequisites are automatically installed. Please proceed with script installation.

For self-deploying Func, refer to Self-deploying Func

Install Script

Note: Please prepare the required Huawei Cloud AK in advance (For simplicity, you can directly grant the global read-only permission Tenant Guest).

Activate Script on Managed Version

  1. Log in to the Guance console.
  2. Click the [Integration] menu, select [Cloud Account Management].
  3. Click [Add Cloud Account], select [Huawei Cloud], fill in the required information on the interface. If the cloud account information has been configured before, ignore this step.
  4. Click [Test]. After a successful test, click [Save]. If the test fails, please check if the relevant configuration information is correct and test again.
  5. Click [Cloud Account Management]. You can see the added cloud account in the list. Click the corresponding cloud account to enter its details page.
  6. Click the [Integration] button on the cloud account details page. Under the Not Installed list, find Huawei Cloud EVS Disk, click the [Install] button, and install via the pop-up installation interface.

Manually Activate Script

  1. Log in to the Func console, click [Script Market], enter the Guance script market, search for integration_huaweicloud_evs.
  2. After clicking [Install], enter the corresponding parameters: Huawei Cloud AK, SK, and account name.
  3. Click [Deploy Startup Script]. The system will automatically create the Startup script set and configure the corresponding startup scripts.
  4. After activation, you can see the corresponding automatic trigger configuration under "Management / Automatic Trigger Configuration". Click [Execute] to run it immediately without waiting for the scheduled time. Wait a moment, then you can check the execution task records and corresponding logs.

Verification

  1. Under "Management / Automatic Trigger Configuration", confirm whether the corresponding task has the corresponding automatic trigger configuration. You can also check the corresponding task records and logs for any exceptions.
  2. In Guance, check under "Infrastructure - Resource Catalog" to see if asset information exists.
  3. In Guance, check under "Metrics" to see if there is corresponding monitoring data.

Metrics

Huawei Cloud EVS Disk metrics are located under the huaweicloud_sys_evs Measurement. Below is the metric description.

Metric Metric Name Description Unit
disk_device_read_bytes_rate Disk Read Bandwidth This metric counts the amount of data read from the measured object per second. bytes/s
disk_device_write_bytes_rate Disk Write Bandwidth This metric counts the amount of data written to the measured object per second. bytes/s
disk_device_read_requests_rate Disk Read IOPS This metric counts the number of read requests from the measured object per second. requests/s
disk_device_write_requests_rate Disk Write IOPS This metric counts the number of write requests to the measured object per second. requests/s
disk_device_queue_length Average Queue Length This metric counts the average number of read or write operation requests waiting to be completed on the measured object during the measurement period. count
disk_device_io_util Disk Read/Write Utilization This metric counts the percentage of time the measured object spent processing read or write operations during the measurement period. %
disk_device_write_bytes_per_operation Average Write Operation Size This metric counts the average number of bytes transferred per write IO operation for the measured object during the measurement period. KB/op
disk_device_read_bytes_per_operation Average Read Operation Size This metric counts the average number of bytes transferred per read IO operation for the measured object during the measurement period. KB/op
disk_device_write_await Average Write Operation Latency This metric counts the average time taken per write IO operation for the measured object during the measurement period. ms/op
disk_device_read_await Average Read Operation Latency This metric counts the average time taken per read IO operation for the measured object during the measurement period. ms/op
disk_device_io_svctm Average IO Service Time This metric counts the average service time per read or write IO operation for the measured object during the measurement period. ms/op
disk_device_io_iops_qos_num IOPS Limit Reached (Count) This metric counts the number of times the IOPS of the measured object reached its limit. count
disk_device_io_iobw_qos_num Bandwidth Limit Reached (Count) This metric counts the number of times the bandwidth of the measured object reached its limit. count
