ECS Metrics

Function Description

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

Namespace

SYS.ECS

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 OTC tools 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 OTC Tools 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 OTC Tools installed.

disk_read_bytes_rate

Disk Read Bandwidth

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

Disk Write Bandwidth

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

Disk Read IOPS

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

Disk Write IOPS

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

System Status Check Failed

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 more 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

ib_card_state

InfiniBand NIC status

This metric is used to monitor the status of an InfiniBand NIC on a high-performance h2 ECS to ensure proper InfiniBand NIC running.

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

  • 0: The system is running properly. That is, the InfiniBand NIC is functional.
  • 1: The system is not running properly. That is, the InfiniBand NIC malfunctions.

0 or 1

Monitored object: ECS

NOTE:

Only Mellanox EDR 100 GB single-port InfiniBand NICs are supported.

NOTE:

The image based on which the target ECS is created must have OTC Tools installed. Otherwise, the Memory Usage and Disk Usage metrics are unavailable. For details about how to install the OTC Tools, visit https://github.com/UVP-Tools/UVP-Tools/.
