CDM Metrics

Function

Cloud Eye monitors the running status of cloud services and usage of each metric, and creates alarm rules for monitoring metrics.

After you create a CDM cluster, Cloud Eye automatically associates with CDM monitoring metrics to help you understand the running status of the CDM cluster.

This section describes the CDM metrics that can be monitored by Cloud Eye as well as their namespaces and dimensions.
For details about CDM monitoring metrics, see Querying CDM Metrics.
For details about how to set alarm rules, see Configuring CDM Alarm Rules.

Prerequisites

You have obtained required Cloud Eye permissions.

Namespace

SYS.CDM

Metrics

Table 1 lists the CDM metrics.

**Table 1** CDM metrics
ID	Name	Description	Value Range	Monitored Object	Monitoring Period (Raw Data)
bytes_in	Bytes In	Measures the network inbound rate of the monitored object. Unit: byte/s	≥ 0 bytes/s	Cloud Data Migration	1 minute
bytes_out	Bytes Out	Measures the network outbound rate of the monitored object. Unit: byte/s	≥ 0 bytes/s	Cloud Data Migration	1 minute
cpu_usage	CPU Usage	Measures the CPU usage of the monitored object. Unit: %	0% to 100%	Cloud Data Migration	1 minute
mem_usage	Memory Usage	Measures the memory usage of the monitored object. Unit: %	0% to 100%	Cloud Data Migration	1 minute
pg_pending_job	Number of Queued Jobs	Number of jobs in the PENDING state in the CDM instance. Unit: count NOTE: This metric is available in version 2.10.0.300 and later versions.	>=0	Cloud Data Migration	1 minute
pending_threads	Maximum Concurrent Extractors	Number of concurrent extraction threads in the Waiting state in the CDM instance. Unit: count NOTE: This metric is available in version 2.10.0.300 and later versions.	>=0	Cloud Data Migration	1 minute
disk_usage	Disk Usage	Measures the disk usage of the physical server accommodating the monitored ECS, which is not accurate as that obtained on the monitored ECS. Unit: %	0.001% to 90%	Cloud Data Migration	1 minute
disk_io	Disk I/O	Measures the bytes read from and written to a disk per second on the physical server accommodating the monitored ECS, which is not accurate as those obtained on the monitored ECS. Unit: Byte/s	0 GB to 10 GB	Cloud Data Migration	1 minute
tomcat_heap_usage	Heap Memory Usage	Measures the heap memory usage of the physical server accommodating the monitored ECS, which is not accurate as that obtained on the monitored ECS. Unit: %	0.001% to 90%	Cloud Data Migration	1 minute
tomcat_connect	Tomcat Concurrent Connections	Measures the number of Tomcat concurrent connections on the physical server.	0 to 2,147,483,647	Cloud Data Migration	1 minute
tomcat_thread_count	Tomat Threads	Measures the number of Tomcat threads on the physical server.	0 to 2,147,483,647	Cloud Data Migration	1 minute
pg_connect	Database Connections	Measures the number of Postgres database connections on the physical server.	0 to 2,147,483,647	Cloud Data Migration	1 minute
pg_submission_row	Rows	Measures the number of rows in the submission table of the Postgres database on the physical server.	0 to 2,147,483,647	Cloud Data Migration	1 minute
pg_failed_job_rate	Job Failure Rate	Measures the job failure rate of the sqoop process on the physical server. Unit: %	0.001% to 100%	Cloud Data Migration	1 minute
inodes_usage	Inodes Usage	Measures the disk inodes usage of the physical server accommodating the monitored ECS, which is not accurate as that obtained on the monitored ECS. Unit: %	0.001% to 100%	Cloud Data Migration	1 minute
