GCP Compute Engine Instance by HTTP

Overview

This template is designed to monitor Google Cloud Platform Compute Engine instances by Zabbix.

Requirements

Zabbix version: 7.4 and higher.

Tested versions

This template has been tested on:

  • GCP Compute Engine

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

This template will be automatically connected to discovered entities with all their required parameters pre-defined.

Macros used

Name Description Default
{$GCP.DATA.TIMEOUT}

A response timeout for an API.

 15s
{$GCP.TIME.WINDOW}

Time interval for the data requests.

Supported usage type:

1. The default update interval for most of the items.

2. The minimal time window for the data requested in the Monitoring Query Language REST API request.

 5m
{$GCP.PROXY}

Sets HTTP proxy value. If this macro is empty then no proxy is used.

Items

Name Description Type Key and additional info
Metrics get

GCP Compute Engine metrics get in raw format.

 Script gcp.gce.metrics.get

Preprocessing

  • Check for not supported value: any error

    ⛔️Custom on fail: Discard value
Firewall: Dropped packets

Count of incoming packets dropped by the firewall.

 Dependent item gcp.gce.firewall.dropped_packets_count

Preprocessing

  • JSON Path: $.dropped_packets_count
Firewall: Dropped bytes

Count of incoming bytes dropped by the firewall.

 Dependent item gcp.gce.firewall.dropped_bytes_count

Preprocessing

  • JSON Path: $.dropped_bytes_count
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 reserved 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.

 Dependent item gcp.gce.cpu.guest_visible_vcpus

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.

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.
