Monitoring Compute Engine service
Scenario
Dennis is a Google Cloud Platform Technology Specialist in an IT organization. He is responsible for monitoring the virtual machines that are created by using the Google Compute Engine service. He monitors the performance of the virtual machines so that he can identify the current capacity of resources and forecast the future requirements.
Current problem: Dennis wants to know whether the virtual machines that are created by using the Google Compute Engine service are running smoothly.
He wants to determine the level of consumed resources, that is, the number of disk reads and writes, CPU usage, network traffic, and status of the virtual machine.
Solution: Dennis can use the Compute Engine metrics to quickly get the information that he wants. The metrics in the following monitor types can help him identify how the resources are currently being utilized by the Compute Engine instance.
Prerequisites: Let us assume that John, the TrueSight Presentation Server administrator, has already completed the necessary prerequisite tasks to set up the PATROL for Google Cloud Platform product so that Dennis can use the monitor type to view data.
- Define a monitoring policy from the TrureSight console.
- Ensure that you have provided the required user permissions before configuring the KM.
- Configure the PATROL for Google Cloud Platform product for monitoring. Ensure that Compute Engine monitoring is enabled while configuring the KM.
- Grant Dennis the required permissions to view the monitored data
Workflow
The following illustration provides a high-level view of the process.
Steps
Dennis performs the following steps:
Open the Devices page
- Click Monitoring > Devices.
Select the Device that contains the configured Google Cloud Platform project
The Device Details page is displayed. In the Monitors tab, expand the Google Cloud Project monitor to view the configured monitor types.
Select the Google Compute Engine monitor. This is a container that holds the virtual machines instances.
Expand the Compute Engine Instance monitor to view the Disks, Networks, and Processors available for that virtual machine.
