Basic ECS Metrics

Description

This section describes basic monitoring metrics reported by ECS to Cloud Eye. You can use Cloud Eye to view these metrics and alarms generated for ECSs.

Namespace

SYS.ECS

Basic ECS Metrics

Basic ECS metrics vary depending on ECS OSs and types. For details, seeTable 1. Y indicates that the metric is supported, and x indicates that the metric is not supported.

Note

To monitor the memory usage and disk usage, you need to install the Agent on your ECS.

Table 2 describes these basic ECS metrics.

The monitoring intervals for the following ECSs with raw monitoring metrics are as follows:

  • KVM and QingTian ECS: 5 minutes

cpu_util

CPU Usage

CPU usage of an ECS

Unit: Percent

Formula: CPU usage of an ECS/Number of vCPUs in the ECS

>= 0

ECS

5 minutes

mem_util

Memory Usage

Memory usage of an ECS

This metric is unavailable if the image has no OTC Tools installed.

Unit: Percent

Formula: Used memory of an ECS/Total memory of the ECS

Note

The memory usage of QingTian ECSs cannot be monitored.

>= 0

ECS

5 minutes

disk_util_inband

Disk Usage

Disk usage of an ECS

This metric is unavailable if the image has no OTC Tools installed.

Unit: Percent

Formula: Used capacity of an ECS disk/Total capacity of the ECS disk

>= 0

ECS

5 minutes

disk_read_bytes_rate

Disk Read Bandwidth

Number of bytes read from an ECS disk per second

Unit: byte/s

Formula: Total number of bytes read from an ECS disk/Monitoring interval

byte_out = (rd_bytes - last_rd_bytes)/Time difference

>= 0

ECS

5 minutes

disk_write_bytes_rate

Disk Write Bandwidth

Number of bytes written to an ECS disk per second

Unit: byte/s

Formula: Total number of bytes written to an ECS disk/Monitoring interval

>= 0

ECS

5 minutes

disk_read_requests_rate

Disk Read IOPS

Number of read requests sent to an ECS disk per second

Unit: request/s

Formula: Total number of read requests sent to an ECS disk/Monitoring interval

req_out = (rd_req - last_rd_req)/Time difference

>= 0

ECS

5 minutes

disk_write_requests_rate

Disk Write IOPS

Number of write requests sent to an ECS disk per second

Unit: request/s

Formula: Total number of write requests sent to an ECS disk/Monitoring interval

req_in = (wr_req - last_wr_req)/Time difference

>= 0

ECS

5 minutes

network_incoming_bytes_rate_inband

Inband Incoming Rate

Number of incoming bytes on an ECS per second

Unit: byte/s

Formula: Total number of inband incoming bytes on an ECS/Monitoring interval

>= 0

ECS

5 minutes

network_outgoing_bytes_rate_inband

Inband Outgoing Rate

Number of outgoing bytes on an ECS per second

Unit: byte/s

Formula: Total number of inband outgoing bytes on an ECS/Monitoring interval

>= 0

ECS

5 minutes

network_incoming_bytes_aggregate_rate

Outband Incoming Rate

Number of incoming bytes on an ECS per second on the hypervisor

Unit: byte/s

Formula: Total number of outband incoming bytes on an ECS/Monitoring interval

This metric is unavailable if SR-IOV is enabled.

>= 0

ECS

5 minutes

network_outgoing_bytes_aggregate_rate

Outband Outgoing Rate

Number of outgoing bytes on an ECS per second on the hypervisor

Unit: byte/s

Formula: Total number of outband outgoing bytes on an ECS/Monitoring interval

This metric is unavailable if SR-IOV is enabled.

>= 0

ECS

5 minutes

ib_card_state

InfiniBand NIC status

Status of an InfiniBand NIC on an H2 ECS

The system periodically checks the 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. When the physical NIC corresponding to a virtual NIC becomes faulty, for example, the network cable is not securely connected to the NIC, the switch or adapter is incompatible with the InfiniBand NIC, or the NIC is disabled, the returned value is 1.

Note

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