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.
