Supported Monitoring Metrics (with Agent Installed)

Description

This section describes monitoring metrics reported by BMS to Cloud Eye as well as their namespaces and dimensions. You can use the management console or APIs provided by Cloud Eye to query the metrics of the monitored objects and alarms generated for BMS.

After installing the Agent on a BMS, you can view its OS monitoring metrics. Monitoring data is collected at an interval of 1 minute.

Monitored Object

Monitoring Interval (Raw Data)

cpu_usage

(Agent) CPU Usage

CPU usage of the monitored object

Obtain its value by checking metric value changes in the /proc/stat file in a collection period.

Run the top command to check the %Cpu(s) value.

Unit: percent

0-100%

BMS

1 minute

load_average5

(Agent) 5-Minute Load Average

CPU load averaged from the last 5 minutes

Obtain its value by dividing the load5/ value in /proc/loadavg by the number of logical CPUs.

Run the top command to check the load5 value in the /proc/loadavg file.

≥ 0

mem_usedPercent

(Agent) Memory Usage

Memory usage of the monitored object

Obtain its value by checking the file /proc/meminfo. Memory Usage = (MemTotal - MemAvailable)/MemTotal

Unit: percent

0-100%

BMS

1 minute

mountPointPrefix_disk_free

(Agent) Available Disk Space

Available disk space of the monitored object

Run the df -h command to check the data in the Avail column.

The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).

Unit: GB

≥ 0 GB

BMS

1 minute

mountPointPrefix_disk_usedPercent

(Agent) Disk Usage

Disk usage of the monitored object. It is calculated as follows: Disk Usage = Used Disk Space/Disk Storage Capacity.

Disk Usage = Used Disk Space/Disk Storage Capacity

The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).

Unit: percent

0-100%

BMS

1 minute

disk_ioUtils

(Agent) Disk I/O Usage

Disk I/O usage of the monitored object

Obtain its value by checking data changes in the thirteenth column of the corresponding device in the /proc/diskstats file in a collection period.

The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).

Unit: percent

0-100%

BMS

1 minute

disk_inodesUsedPercent

(Agent) Percentage of Total inode Used

Percentage of used index nodes on the disk

Run the df -i command to check data in the IUse% column.

The path of the mount point prefix cannot exceed 64 characters. It must start with a letter, and contain only digits, letters, hyphens (-), dots (.), and swung dashes (~).

Unit: percent

0-100%
