Table 1 describes the basic monitoring metrics of Workspace Application Streaming.

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

**Table 1** Basic monitoring metrics supported by Workspace Application Streaming
Metric ID	Metric Name	Metric Description	Value Range	Unit	Number System	Monitored Object (Dimension)	Monitoring Interval (Raw Metrics and KVM Only)
cpu_util	CPU Usage	CPU usage of an ECS. This metric is used to show the CPU usage of the physical server accommodating the monitored ECS, which is not as accurate as the CPU usage obtained on the monitored ECS. For details, see Formula: CPU usage of an ECS/Number of CPU cores on the ECS	0-100	%	N/A	Application Streaming instance	1 minute
mem_util	Memory Usage	Memory usage of an ECS. Formula: Memory usage of an ECS/Total memory of the ECS	0-100	%	N/A	Application Streaming instance	1 minute
disk_util_inband	Disk Usage	Disk usage of an ECS. Formula: Disk usage of an ECS/Total disk capacity of the ECS	0-100	%	N/A	Application Streaming instance	1 minute
disk_read_bytes_rate	Disk Read Rate	Number of bytes read from an ECS per second. Formula: Total number of bytes read from an ECS/Monitoring interval byte_out = (rd_bytes - last_rd_bytes)/Time difference	≥ 0	byte/s	1024(IEC)	Application Streaming instance	1 minute
disk_write_bytes_rate	Disk Write Rate	Number of bytes written to an ECS per second. Formula: Total number of bytes written to a disk of the ECS/Monitoring interval	≥ 0	byte/s	1024(IEC)	Application Streaming instance	1 minute
disk_read_requests_rate	Disk Read IOPS	Number of read requests sent to an ECS per second. Formula: Total number of read requests sent to a disk of the ECS/Monitoring interval req_out = (rd_req - last_rd_req)/Time difference	≥ 0	Request/s	N/A	Application Streaming instance	1 minute
disk_write_requests_rate	Disk Write IOPS	Number of write requests sent to an ECS per second. Formula: Total number of write requests sent to a disk of the ECS/Monitoring interval req_in = (wr_req - last_wr_req)/Time difference	≥ 0	Request/s	N/A	Application Streaming instance	1 minute
network_incoming_bytes_rate_inband	Inband Incoming Rate	Number of incoming bytes on an ECS per second. Formula: Total number of inband incoming bytes on an ECS/Monitoring interval	≥ 0	byte/s	1024(IEC)	Application Streaming instance	1 minute
network_outgoing_bytes_rate_inband	Inband Outgoing Rate	Number of outgoing bytes on an ECS per second. Formula: Total number of inband outgoing bytes on an ECS/Monitoring interval	≥ 0	byte/s	1024(IEC)	Application Streaming instance	1 minute
network_incoming_bytes_aggregate_rate	Outband Incoming Rate	Number of incoming bytes on an ECS per second on the hypervisor. Formula: Total number of outband incoming bytes on an ECS/Monitoring interval This metric is unavailable if SR-IOV is enabled.	≥ 0	byte/s	1024(IEC)	Application Streaming instance	1 minute
network_outgoing_bytes_aggregate_rate	Outband Outgoing Rate	Number of outgoing bytes on an ECS per second on the hypervisor. Formula: Total number of outband outgoing bytes on an ECS/Monitoring interval This metric is unavailable if SR-IOV is enabled.	≥ 0	byte/s	1024(IEC)	Application Streaming instance	1 minute
user_session_num	Number of User Sessions	Number of user sessions on an ECS.	0-100	%	N/A	Application Streaming instance	1 minute
