Workloads metrics

 

Table 4. Workloads metrics

Metric name	Description
CPU Usage Rate	CPU usage rate on all cores in millicores/second.
CPU Request	CPU request (the guaranteed amount of resources) in millicores.
CPU Limit	CPU hard limit in millicores.
CPU Utilization	Percentage of CPU usage / CPU limit if user configured CPU limit for this pod.
Memory Usage	Total memory usage in bytes.
Memory Working Set	Total working set usage. Working set is the memory being used and not easily dropped by the kernel.
Memory RSS	RSS memory usage.
Memory Cache	Number of bytes of page cache memory.
Memory Swap	Container swap usage in bytes.
Memory Request	Memory request (the guaranteed amount of resources) in bytes.
Memory Limit	Memory hard limit in bytes.
Memory Utilization	Percentage of Memory usage / Memory limit if user configured Memory limit for this pod.
Network Send Bytes Rate	Network send bytes per second.
Network Receive Bytes Rate	Network receive bytes per second.
Network Transfer Bytes Rate	Network send and receive bytes per second.
Network Send Errors Rate	Network send errors count per second.
Network Receive Errors Rate	Network receive errors count per second.
Network Transfer Errors Rate	Network send and receive errors count per second.
Network Send Packets Rate	Network send packets count per second.
Network Receive Packets Rate	Network receive packets count per second.
Network Transfer Packets Rate	Network send and receive packets count per second.
Network Send Dropped Packets Rate	Network send dropped packets count per second.
Network Receive Dropped Packets Rate	Network receive dropped packets count per second.
Network Transfer Dropped Packets Rate	Network send and receive dropped packets count per second.
Filesystem Usage	Number of bytes that are consumed by the container on this filesystem.
Filesystem Capacity	Number of bytes that can be consumed by the container on this filesystem.
Filesystem Utilization	Percentage of Filesystem Usage / Filesystem Capacity.
Filesystem Read Bytes Rate	Filesystem read bytes per second.
Filesystem Write Bytes Rate	Filesystem write bytes per second.
Filesystem Read Rate	Filesystem read counts per second.
Filesystem Write Rate	Filesystem write counts per second.

 

NOTE:   • Workloads metrics are for the following workloads types, Deployment, Daemon Set, Stateful Set, Replica Set, Replication Controller, Cron Job, Job, and Pod. • For workloads types except Pods, the metrics values come from the aggregated metrics values of the related Pods.
