Description

Value Range

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

BMS

1 minute

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

mountPointPrefix_disk_ioUtils and volumePrefix_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

mountPointPrefix_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%

net_bitSent

(Agent) Outbound Bandwidth

Number of bits sent by this NIC per second

Check metric value changes in the /proc/net/dev file in a collection period.

Unit: bit/s

net_packetRecv

(Agent) NIC Packet Receive Rate

Number of packets received by this NIC per second

Check metric value changes in the /proc/net/dev file in a collection period.

Unit: count/s

≥ 0 counts/s

BMS
