Considering the answer posted and question, If we think we do not need Stackdriver monitoring, we can disable stackdriver monitoring API using bellow steps:
- From the Cloud Console,go to APIs & Services.
- Select Stackdriver Monitoring API.
- Click Disable API.
In addition you can view Stackdriver usage by billing account and also can estimate cost using Stackdriver pricing calculator [a] [b].
View Stackdriver usage by billing account:
- From anywhere in the Cloud Console, click Navigation menu and select Billing.
- If you have more than one billing account, select Go to linked billing account to
view the current project's billing account. To locate a different billing account,
select Manage billing accounts and choose the account for which you'd like to get
usage reports.
- Select Reports.
4.Select Group By > SKU. This menu might be hidden; you can access it by clicking Show
Filters.
- From the SKUs drop-down list, make the following selections:
- Log Volume (Stackdriver Logging usage)
- Spans Ingested (Stackdriver Trace usage)
- Metric Volume and Monitoring API Requests (Stackdriver Monitoring usage)
- Your usage data, filtered by the SKUs you selected, will appear.
You can also select just one or some of these SKUs if you don't want to group your usage data.
Note: If your usage of any of these SKUs is 0, they don't appear in the Group By > SKU pull-down menu. For example, who use only the Cloud console might never generate API requests, so Monitoring API Requests doesn't appear in the list.
Use the Stackdriver pricing calculator [b]:
- Add your current or projected Monitoring usage data to the Metrics section and click Add to estimate.
- Add your current or projected Logging usage data to the Logs section and click Add to estimate.
- Add your current Trace usage data to the Trace spans section and click Add to estimate.
- Once you have input your usage data, click Estimate.
Estimates of your future Stackdriver bills appear. You can also Email Estimate or Save Estimate.
