Monitoring Metrics

List of all supported metrics

General Metrics

Metric	Unit	Description
CPU Utilization	percentage	Total CPU utilization (all cores). 100% here means there is no CPU idle time at all.
System Load 1	system load	Current system load, i.e. the number of processes using CPU or waiting for system resources (usually CPU and disk).
Available Memory Size	percentage	Available Memory is estimated by the kernel, as the amount of RAM that can be used by userspace processes, without causing swapping.
Available Swap Space	megabytes	System swap memory usage. Swap space is used when the amount of physical memory (RAM) is full. When the system needs more memory resources and RAM is full, inactive pages in memory are moved to the swap space (usually a disk, a disk partition or a file).
Uptime	seconds
System Load 5	system load	Current system load, i.e. the number of processes using CPU or waiting for system resources (usually CPU and disk).
System Load 15	system load	Current system load, i.e. the number of processes using CPU or waiting for system resources (usually CPU and disk).
CPU Utilization Without Low Priority Processes	percentage	Total CPU utilization (all cores). The used metric is calculated as 100% - cpu idle time so is a sum of user, system, softirq, irq, guest, iowait, nice and steal. Some processes with low priority may be occupying the CPU but can be killed to make place for high priority tasks. The metric used_no_low_priority_processes does not include iowait, nice and steal and shows the CPU occupied only by high priority processes.
Available Memory	megabytes	Available Memory is estimated by the kernel, as the amount of RAM that can be used by userspace processes, without causing swapping.

Network Metrics

Metric	Unit	Description
Network Inbound Bandwidth	megabits/s	Total bandwidth of all physical network interfaces. This does not include lo, VPNs, network bridges, IFB devices, bond interfaces, etc. Only the bandwidth of physical network interfaces is aggregated.
Network Outbound Bandwidth	megabits/s	Total bandwidth of all physical network interfaces. This does not include lo, VPNs, network bridges, IFB devices, bond interfaces, etc. Only the bandwidth of physical network interfaces is aggregated.

Storage Metrics

Metric	Unit	Description
Root Disk Available Space	gigabytes	Root Disk Available Space
Disk Read Bandwidth	kilobytes/s	Amount of data transferred to and from disk.
Disk Write Bandwidth	kilobytes/s	Amount of data transferred to and from disk.
Disk Read Operation per Second	operations/s	Completed disk I/O operations. Keep in mind the number of operations requested might be higher since the system is able to merge adjacent to each other.
Disk Write Operation per Second	operations/s	Completed disk I/O operations. Keep in mind the number of operations requested might be higher since the system is able to merge adjacent to each other.
Root Disk Used Space	gigabytes
Used Root Disk	percentage
Disk I/O Operation per Second	operations/s	Completed disk I/O operations. Keep in mind the number of operations requested might be higher since the system is able to merge adjacent to each other.
Disk Bandwidth	kilobytes/s	Amount of data transferred to and from disk.
