GCP Compute Metrics¶

This page lists the Compute metrics collected by the GCP app.

In the table below, the metric type prefixes are omitted. For example, the full name of the dropped_bytes_count metric, of type firewall, is compute.googleapis.com/firewall/dropped_bytes_count.

Firewall¶

Metric type prefix: compute.googleapis.com/firewall

Metric	Description
`dropped_bytes_count`	Count of incoming bytes dropped by the firewall.
`dropped_packets_count`	Count of incoming packets dropped by the firewall.

Guest¶

`disk/queue_length`	The queue length on the disk averaged over the last 60 seconds. For Container-Optimized OS, or Ubuntu running GKE.
`disk/weighted_io_time`	The cumulative weighted IO time spent on the disk. For Container-Optimized OS, or Ubuntu running GKE.

`memory/bytes_used`	Memory usage by each memory state, in Bytes. Summing values of all states yields the total memory on the machine. For Container-Optimized OS, or Ubuntu running GKE.
`memory/dirty_used`	Dirty pages usage, in Bytes. For Container-Optimized OS, or Ubuntu running GKE.

Instance¶

Metric type prefix: compute.googleapis.com/instance

Metric	Description
`cpu/guest_visible_vcpus`	Number of vCPUs visible inside the guest. For many GCE machine types, the number of vCPUs visible inside the guest is equal to the `compute.googleapis.com/instance/cpu/reserved_cores` metric. For shared-core machine types, the number of guest-visible vCPUs differs from the number of resereved cores. For example, e2-small instances have two vCPUs visible inside the guest and 0.5 fractional vCPUs reserved. Therefore, for an e2-small instance, `compute.googleapis.com/instance/cpu/guest_visible_vcpus` has a value of 2 and `compute.googleapis.com/instance/cpu/reserved_cores` has a value of 0.5.
`cpu/reserved_cores`	Number of vCPUs reserved on the host of the instance.
`cpu/scheduler_wait_time`	Wait time is the time a vCPU is ready to run, but unexpectedly not scheduled to run. The wait time returned here is the accumulated value for all vCPUs. The time interval for which the value was measured is returned by Monitoring in whole seconds as start_time and end_time. This metric is only available for VMs that belong to the e2 family or to overcommitted VMs on sole-tenant nodes.
`cpu/usage_time`	Delta vCPU usage for all vCPUs, in vCPU-seconds. To compute the per-vCPU utilization fraction, divide this value by (end-start)*N, where end and start define this value’s time interval and N is `compute.googleapis.com/instance/cpu/reserved_cores` at the end of the interval. This value is reported by the hypervisor for the VM and can differ from `agent.googleapis.com/cpu/usage_time`, which is reported from inside the VM.
`cpu/utilization`	Fractional utilization of allocated CPU on this instance. Values are typically numbers between 0.0 and 1.0 (but some machine types allow bursting above 1.0). Charts display the values as a percentage between 0% and 100% (or more). This metric is reported by the hypervisor for the VM and can differ from `agent.googleapis.com/cpu/utilization`, which is reported from inside the VM.
`disk/max_read_bytes_count`	Disk’s maximum per-second read throughput over a period of time specified by the user. The period must be one minute or longer.
`disk/max_read_ops_count`	Disk’s maximum per-second read requests count over a period of time specified by the user. The period must be one minute or longer.
`disk/max_write_bytes_count`	Disk’s maximum per-second write throughput over a period of time specified by the user. The period must be one minute or longer.
`disk/max_write_ops_count`	Disk’s maximum per-second write requests count over a period of time specified by the user. The period must be one minute or longer.
`disk/read_bytes_count`	Count of bytes read from disk.
`disk/read_ops_count`	Count of disk read IO operations.
`disk/write_bytes_count`	Count of bytes written to disk.
`disk/write_ops_count`	Count of disk write IO operations.
`integrity/early_boot_validation_status`	The validation status of early boot integrity policy.
`integrity/late_boot_validation_status`	The validation status of late boot integrity policy.
`network/received_bytes_count`	Count of bytes received from the network.
`network/received_packets_count`	Count of packets received from the network.
`network/sent_bytes_count`	Count of bytes sent over the network.
`network/sent_packets_count`	Count of packets sent over the network.
`uptime`	Delta of how long the VM has been running, in seconds. Note: to get the total number of seconds since VM start, use compute.googleapis.com/instance/uptime_total.
`uptime_total`	Elapsed time since the VM was started, in seconds.
