ECS Monitoring Metrics

Function

This section describes monitoring metrics reported by ECS to CES as well as their namespaces and dimensions. You can use APIs provided by CES to query the monitoring metrics of the monitored object and alarms generated for ECS.

Namespace

SYS.ECS

Monitoring Metrics

Metric

Name

Description

Value Range

Remarks

cpu_util

CPU Usage

This metric is used to show CPU usages (%) of monitored objects.

0% to 100%

Monitored object: ECS

NOTE:

The metrics collected using vmtools are accurate.

mem_util

Memory Usage

This metric is used to show memory usages (%) of monitored objects.

0% to 100%

Monitored object: ECS

NOTE:

This metric is unavailable if the image has no vmtools installed.

disk_util_inband

Disks Usage

This metric is used to show disk usages (%) of monitored objects.

0% to 100%

Monitored object: ECS

NOTE:

This metric is unavailable if the image has no vmtools installed.

disk_read_bytes_rate

Disks Read Rate

This metric is used to show the number of bytes read from the monitored object per second (bytes/second).

≥ 0 bytes/s

Monitored object: ECS

disk_write_bytes_rate

Disks Write Rate

This metric is used to show the number of bytes written to the monitored object per second (bytes/second).

≥ 0 bytes/s

Monitored object: ECS

disk_read_requests_rate

Disks Read Requests

This metric is used to show the number of read requests sent to the monitored object per second (requests/second).

≥ 0

Monitored object: ECS

disk_write_requests_rate

Disks Write Requests

This metric is used to show the number of write requests sent to the monitored object per second (requests/second).

≥ 0

Monitored object: ECS

network_incoming_bytes_rate_inband

Inband Incoming Rate

This metric is used to show the number of incoming bytes received by the monitored object per second (bytes/second).

≥ 0 bytes/s

Monitored object: ECS

network_outgoing_bytes_rate_inband

Inband Outgoing Rate

This metric is used to show the number of outgoing bytes sent by the monitored object per second (bytes/second).

≥ 0 bytes/s

Monitored object: ECS

network_incoming_bytes_aggregate_rate

Outband Incoming Rate

This metric is used to show the number of incoming bytes received by the monitored object per second (bytes/second) at the virtualization layer.

≥ 0 bytes/s

Monitored object: ECS

NOTE:

This metric is unavailable if SR-IOV is enabled.

network_outgoing_bytes_ aggregate_rate

Outband Outgoing Rate

This metric is used to show the number of outgoing bytes sent by the monitored object per second (bytes/second) at the virtualization layer.

≥ 0 bytes/s

Monitored object: ECS

NOTE:

This metric is unavailable if SR-IOV is enabled.

inst_sys_status_error

Failed to check the system status.

This metric is used to monitor the cloud platform on which ECSs run.

The system periodically checks the system status and returns check results using value 0 or 1.

  • 0: The system is running properly. All check items are normal.
  • 1: The system is not running properly. One or multiple check items are abnormal.

    When the power source of the physical host fails or the hardware/software becomes faulty, the check result is 1.

0 or 1

Monitored object: ECS

Value

instance_id

Specifies the ECS ID.
