ECS Monitoring Metrics

Function

This section describes metrics reported by ECS to Cloud Eye as well as their namespaces and dimensions. You can use APIs provided by Cloud Eye to query the 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%	ECS monitored 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%	ECS monitored 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%	ECS monitored NOTE: This metric is unavailable if the image has no VMTools 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 (byte/s).	≥ 0	ECS monitored
disk_write_bytes_rate	Disk Write Bandwidth	This metric is used to show the number of bytes written to the monitored object per second (byte/s).	≥ 0	ECS monitored
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	ECS monitored
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	ECS monitored
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 (byte/s).	≥ 0	ECS monitored
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 (byte/s).	≥ 0	ECS monitored
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 (byte/s) at the virtualization layer.	≥ 0	ECS monitored 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 (byte/s) at the virtualization layer.	≥ 0	ECS monitored 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	ECS monitored

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