Host View
The host view displays information about host resource usage and health status, as well as common metrics of system devices such as disks and file systems, so you can better monitor a node.
Metric Description
You can view the host metrics in the following table.
Metric |
Unit |
Description |
---|---|---|
CPU Usage |
% |
Usage of each CPU core. |
Load Average |
N/A |
CPU contention.
|
Used Memory |
byte |
Memory usage in each mode. |
Memory Usage |
% |
Host memory usage. |
Disk Written |
byte/s |
Write rate of each disk. |
Disk Read |
byte/s |
Read rate of each disk. |
Used Disk Space |
byte |
Used and available disk space. |
Disk Space Usage |
% |
Disk usage of each device. |
Disk I/O Latency |
second |
Disk I/O read/write latency, in seconds. |
TCP Connection |
N/A |
The number of TCP sockets.
|
UDP Usage |
N/A |
UDP usage.
|
File Descriptor |
exabyte |
Maximum number of file descriptors. |
Used File Descriptor |
N/A |
The number of allocated file descriptors. |
Socket Usage |
N/A |
Socket usage.
|
Abnormal File System |
N/A |
File system status.
|
Disk I/O Rate |
N/A |
The number of read/write operations on a disk per second. |
Disk Read/Write Latency |
second |
Disk read/write latency. |
I/O Queues |
N/A |
Average I/O queue length of the disk device, which is the weighted number of seconds spent doing I/O operations. A larger value indicates better disk performance of the node. |
Process State |
N/A |
The number of processes in each state. |
Connection Tracking Table Entries |
N/A |
|
Metric List
Metric |
Type |
Description |
---|---|---|
node_cpu_seconds_total |
Counter |
Seconds the CPUs spent in each mode. |
node_load1 |
Gauge |
Average CPU load within 1 minute, which reflects the competition of CPU resources.
|
node_load15 |
Gauge |
Average CPU load within 15 minutes. |
node_memory_MemTotal_bytes |
Gauge |
Total memory of a node. |
node_memory_MemAvailable_bytes |
Gauge |
Available memory of a node. |
node_disk_written_bytes_total |
Gauge |
Total number of bytes written successfully. |
node_disk_read_bytes_total |
Gauge |
Total number of bytes read successfully. |
node_filesystem_size_bytes |
Gauge |
