Metrics

CPU

Metric	Unit	Description
cpu_num	CPUs	The number of CPUs available in the system (physical and logical)
cpu_util	percent	The average CPU utilization % across all the CPUs (i.e., how much time on average the CPUs are busy doing work)
cpu_util_details	percent	The average CPU utilization % broken down by usage type and cpu number (e.g., cp1 user, cp2 system, cp3 soft-irq)
cpu_load_avg	tasks	The system load average (i.e., the number of active tasks in the system)

Memory

Metric	Unit	Description
mem_util	percent	The memory utilization % (i.e, the % of memory used)
mem_util_nocache	percent	The memory utilization % (i.e., the % of memory used) without considering memory reserved for caching purposes
mem_util_details	percent	The memory utilization % (i.e., the % of memory used) broken down by usage type (e.g., active memory)
mem_used	bytes	The total amount of memory used
mem_used_nocache	bytes	The total amount of memory used without considering memory reserved for caching purposes
mem_total	bytes	The total amount of installed memory
mem_fault_minor	faults/s	The number of minor memory faults (i.e., faults that do not cause disk access) per second
mem_fault_major	faults/s	The number of major memory faults (i.e., faults that cause disk access) per second
mem_fault	faults/s	The number of memory faults (major + minor)
mem_swapins	pages/s	The number of memory pages swapped in per second
mem_swapouts	pages/s	The number of memory pages swapped out per second

Network

Metric	Unit	Description
network_tcp_retrans	retrans/s	The number of network TCP retransmissions per second
network_in_bytes_details	bytes/s	The number of inbound network packets in bytes per second broken down by network device (e.g., wlp4s0)
network_out_bytes_details	bytes/s	The number of outbound network packets in bytes per second broken down by network device (e.g., eth01)

Disk

Notice: you can use a device custom filter to monitor a specific disk with Prometheus. You can find more information on Prometheus queries and the %FILTERS% placeholder here: Prometheus provider and here: Prometheus provider metrics mapping.

Metric	Unit	Description
disk_swap_util	percent	The average space utilization % of swap disks
disk_swap_used	bytes	The total amount of space used by swap disks
disk_util_details	percent	The utilization % of disk, i.e how much time a disk is busy doing work broken down by disk (e.g., disk D://)
disk_iops_writes	ops/s	The average number of IO disk-write operations per second across all disks
disk_iops_reads	ops/s	The average number of IO disk-read operations per second across all disks
disk_iops	ops/s	The average number of IO disk operations per second across all disks
disk_response_time_read	seconds	The average response time of IO read-disk operations
disk_response_time_worst	seconds	The average response time of IO disk operations of the slowest disk
disk_response_time_write	seconds	The average response time of IO write-disk operations
disk_response_time_details	ops/s	The average response time of IO disk operations broken down by disk (e.g., disk /dev/nvme01 )
disk_iops_details	ops/s	The number of IO disk-write operations of per second broken down by disk (e.g., disk /dev/nvme01)
disk_io_inflight_details	ops	The number of IO disk operations in progress (outstanding) broken down by disk (e.g., disk /dev/nvme01)
disk_write_bytes	bytes/s	The number of bytes per second written across all disks
disk_read_bytes	bytes/s	The number of bytes per second read across all disks
disk_read_write_bytes	bytes/s	The number of bytes per second read and written across all disks
disk_write_bytes_details	bytes/s	The number of bytes per second written from the disks broken down by disk and type of operation (e.g., disk /dev/nvme01 and operation WRITE)
disk_read_bytes_details	bytes/s	The number of bytes per second read from the disks broken down by disk and type of operation (e.g., disk /dev/nvme01 and operation READ)

Filesystem

Metric	Unit	Description
filesystem_util	percent	The space utilization % of filesystems broken down by type and device (e.g., filesystem of type overlayfs on device /dev/loop1)
filesystem_used	bytes	The amount of space used on the filesystems broken down by type and device (e.g., filesystem of type zfs on device /dev/nvme01)
filesystem_size	bytes	The size of filesystems broken down by type and device (e.g., filesystem of type ext4 for device /dev/nvme01)
