Google Cloud Compute Engine


Overview

Google Cloud Compute Engine is an Infrastructure as a Service (IaaS) offering that provides a scalable number of virtual machines (VMs) to serve as large compute clusters.

Monitored Parameters

Go to the Monitors Category View by clicking the Monitors tab. Click on the Compute Engine instance available under Google Cloud Platform in the Cloud Apps section. Displayed is the Google Cloud Compute Engine bulk configuration view distributed into three tabs:

  • Availability tab gives the Availability history for the past 24 hours or 30 days.
  • Performance tab gives the Health Status and events for the past 24 hours or 30 days.
  • List view enables you to perform bulk admin configurations.

Cloud monitoring software like Applications Manager provide complete visibility into your Google Cloud Compute Engine environments altogether in a single window based on the following tabs:

Configuration

Parameter Description
Instance name Name of the instance.
Instance ID Unique ID of the instance.
Project ID Unique ID of the project.
Zone Zone in which the instance is created.
Status Current status of the instance. Possible Values: PROVISIONING, STAGING, RUNNING, PENDING_STOP, STOPPING, TERMINATED, REPAIRING, SUSPENDING, SUSPENDED.
Creation Timestamp Date and time at which the instance was created.
Machine Type Virtualized hardware resources available to the instance.
External IP IP Address of the instance.
CPU Platform Base platform of the instance.
OS Platform Operating system running in the instance.
Start Restricted Restriction on the instance to perform start operation (True/False).
Deletion Protection Restriction on the instance to perform delete operation (True/False).

Troubleshooting

1. Data unavailable for performance metrics

  • When an instance is started and polled immediately, data might not be collected for some of the performance metrics. Wait for some time and then poll the monitor to get the data.
  • If the data is still not populated, go to Stackdriver Console and check if data is available.
  • If data is available in Stackdriver and is not getting populated in Applications Manager, reach out to our support with the latest SIF generated with print all logs enabled.

2. Data unavailable for memory and disk utilization metrics

  • Install Stackdriver Monitoring Agent in the instance, to get memory and disk utilization metrics. Click here for information on installing the Stackdriver agent.
  • When an instance is started and polled immediately, data might not be collected for some of the performance metrics. Wait for some time and then poll the monitor to get the data.
