Remote | Indicates whether or not this file system can be accessed remotely. |
KBytes Written | Total amount of bytes written to the filesystem. |
Used FS | The total amount of filesystem space that is currently in use. |
FS Ratio | The existing file system ratio. |
Used Inodes | The total number of used inodes. |
Inode Ratio | The existing inode ratio. |
User Capacity | Capacity available in the file system for the user. |
Utilization | The total utilization of the file system. |
Inode Utilization | The total utilization of inodes in the file system. |
User Utilization | The total amount of utilization of the file system by the specified user. |
Statistics Available | Indicates whether or not I/O statistics are available. 0 = No; 1 = Yes. |
NUMA Node Statistics metrics
The following table provides information about the NUMA Node Statistics metrics for Linux systems.
Metric | Description |
|---|---|
Node ID | The ID of node. |
CPU Idle Time | The measure of unused CPU time in seconds. |
CPU User Time | Measure of application-related CPU activity in seconds. |
CPU System Time | Measure of system-related CPU activity in seconds. |
CPU Wait Time | Interval that the processor spends in an I/O wait state. |
CPU Interrupt Time | Interval that the processor spends handling hardware or software interrupts. |
CPU Involuntary Wait Time | Time (in seconds) that the processor spends in involuntary wait. |
Total Memory | System installed memory in KB. |
Free Memory | Total unused memory in system in KB. |
Active Memory | The size (in KB) of the memory that is currently used by the partition. |
Inactive Memory | The memory (in KB) allocated to a process that is not running. |
Shared Memory | The memory (in KB) that is shared between processes. |
Anonymous Huge Page Memory | The size (in KB) of the huge pages that are not backed by files and are mapped into userspace page tables. |
Total Huge Page Memory | The total size (in KB) of the memory that is allocated to huge pages. |
Free Huge Page Memory | The size (in KB) of the available huge page memory. |
Surplus Huge Page Memory | The size (in KB) of the huge page memory pool that is available due to overcommitment. |
Hit Memory | The number of memory pages that were allocated to the node measured in KB. |
Miss Memory | The number of pages that were allocated on the node due to low memory on the intended node measured in KB. |
Foreign Memory | The number of pages that were intended for this node but allocated to another node measured in KB. |
Interleave Hit Memory | The number of interleave policy pages that were successfully allocated to this node measured in KB. |
Local Node Memory | The number of pages that were allocated on this node by a process on the node measured in KB. |
Other Node Memory | The number of pages that were allocated on this node by a process on another node measured in KB. |
Memory Utilization | The percentage of memory that is used. |
CPU Utilization | The measure of processor load. |
System Busy | The system that is reported as busy. |
NUMA Node Configuration
The following table provides information about the NUMA Node Configuration metrics for Linux systems.
Metric | Description |
|---|---|
Node ID | The ID of NUMA node. |
NUMA Node ID | The ID that represents association of a specific processor with a particular NUMA node. |
Number of Processors | Number of CPUs that are installed in the NUMA node. |
Total Memory | Total amount of RAM that is installed in the NUMA node. |
Processor List | String-based representation of the processors that are associated with the NUMA node. |
