Free Premium Trial: Every new Stackdriver account receives a 30-day free trial of the Premium Tier. When the trial expires, you can upgrade to the Premium Tier or choose the Basic Tier. All projects monitored by an account are subject to the account's service tier. For more information, see Frequently-asked questions.

Additional details

This section contains more details and explanations about Stackdriver pricing.

Start of billing

When your Stackdriver account's free trial expires you must either upgrade your account to the Premium Tier or accept the Basic Tier of service:

  • When you upgrade to the Premium Tier, you will be billed for your chargeable resources. If you upgrade before your free trial ends, then billing begins when your free trial ends.

  • If you choose the Basic Tier, you will not be billed. However, you will lose access to AWS monitoring and logging information; your logs allotment and retention period will be reduced; you won't be able to use the Monitoring agent on your VM instances, and your account will be subject to other Basic Tier limitations.

For more information, see Service tiers and Frequently-asked questions on this page.

Chargeable resources

In the Premium Tier, your Stackdriver account is charged $8.00 per month, prorated hourly, for the following resources. To estimate the Premium Tier pricing for your own system, use the Stackdriver Pricing Calculator.

GCP chargeable resources

  • Each App Engine standard environment instance (running, not idle)
  • Each Compute Engine VM instance (running)
  • Each Container Engine node instance in a cluster
  • Each Cloud SQL instance (runnable)

AWS chargeable resources

  • Each Amazon EC2 VM instance (running)
  • Each Elastic Load Balancer (ELB)
  • Each Elasticache cluster
  • Each RDS instance
  • Ten (10) SQS queues
  • Each SNS topic
  • Each DynamoDB table

Exempt and non-exempt logs

Each log in Stackdriver Logging is classified as exempt or non-exempt. Exempt logs do not count toward your monthly logs allotment and do not have overage charges if you have exceeded your allotment. The following logs are exempt:

Non-exempt logs count against your monthly logs allotment and any overage charges. All logs not listed as exempt are non-exempt, including Data Access audit logs from sources other than BigQuery.

Log allotments and overage charges

Stackdriver service tiers include a monthly allotment of non-exempt logs and an overage charge for logs received over that allotment:

Tier Retention Monthly allotment Overage charge
Basic 7 days 5 GB per project $0.50 per GB
Premium 30 days 10 GB per chargeable resource $0.50 per GB

Log entries are held in Stackdriver Logging for the retention period and then removed. The logs allotment is a limit on the amount of non-exempt logs that your project receives. In Premium Tier accounts, overage charges are billed automatically. In Basic Tier accounts you must sign up to pay overage charges.

How it works. When you approach your monthly logs limit, Stackdriver displays a warning notification in your project. When the allotment limit is reached, one of two things happen:

  • If you are paying for logs overage charges, you are billed for the extra logs and your non-exempt logs continue to flow into Stackdriver Logging.

  • If you are not paying for logs overage charges, Stackdriver Logging discards all new, non-exempt log entries coming into your project for the remainder of the month. However, you can still export your non-exempt logs to avoid losing them entirely.

For example, suppose your project is in the Basic Tier and you do not sign up for logs overage charges. Suppose also your project receives roughly the same amount of non-exempt logs each day, and it reaches its Basic Tier allotment limit at the start of March 28. At that time, Stackdriver begins discarding all non-exempt log entries, even though about 75% of your March logs have already been removed under the 7-day retention policy. On April 1, Stackdriver stops discarding log entries and you see new, non-exempt log entries in your project. However, you still see a 4-day gap in the non-exempt logs, from March 28 until April 1.

In the same example, before you reach your logs allotment limit you can choose to export your non-exempt logs to Google Cloud Storage. In that case, all your non-exempt logs are in Cloud Storage, but you still see a 4-day gap when you look at your logs in Stackdriver Logging. For more information, see Exporting logs.

Exporting logs

You can export the logs you receive to services outside Stackdriver Logging, including Google Cloud Storage, Google BigQuery, and Google Cloud Pub/Sub. You can export both exempt and non-exempt logs, even if you are over your monthly log allotment and you choose not to pay overage charges. Exporting logs has no Stackdriver cost, but you will have storage costs from the service storing your logs. For instructions on how to export logs, see Exporting Logs.

Metric allotments and overage charges

Stackdriver offers access to over a thousand predefined metrics that keep six weeks of data. Your access to predefined metrics depends on your service tier, but there is no limit on your use of the metrics you have access to:

Tier Retention Available predefined metrics
Basic 6 weeks GCP metrics
Premium 6 weeks GCP metrics, AWS metrics, and Stackdriver Monitoring Agent metrics

For a complete list of predefined metrics, see Metrics List.

Stackdriver also lets you define your own metrics, both custom metrics and logs-based metrics. Stackdriver monitors these user-defined metrics and charges for usage above the allotments for your service tier. The allotments and overages treat custom metrics and logs-based metrics together:

Tier Retention Allotment Overage charge
Basic 6 weeks none1 $0.10 per time series per month, and $1.00 per metric descriptor per month
Premium 6 weeks 500 time series per chargeable resource, and 250 metric descriptors per project $0.10 per time series per month, and $1.00 per metric descriptor per month

1 To use any custom or logs-based metrics in the Basic Tier, you must sign up to pay overage charges.

The time series allotment is pooled across resources in the same project. For example, in a project with one custom metric and two chargeable resources, the custom metric can have up to 1,000 time series without going over the allotment.

For more information, see Metrics, Time Series, and Resources, Custom Metrics, and Logs-based Metrics.

For example, as an illustration of custom metric costs, suppose you write a custom metric to duplicate the existing compute.googleapis.com/instance/disk/read_bytes_count metric. You write a measurement for each disk, every minute, from each of your VM instances. For simplicity, assume you have 100 VM instances and each has 2 disks. Here is your usage information:

  • Metric descriptors: 1
  • Time series: 200 (2 per VM instance)
  • Retained data points (6 weeks): 12 million

Here is how overage charges break down:

  • Premium Tier: $0/month. For all Stackdriver services, you pay $800 per month for your 100 VM instances. There are no overage charges for this custom metric because you are well under your allotment: 1 (vs 250) metric descriptors per project and 2 (vs 500) time series per chargeable resource.

  • Basic Tier: $21/month. You must pay overage charges for the custom metric: $1.00 per month for the metric descriptor plus $20.00 per month for 200 time series.

Alerting and notification limitations

In the Basic Tier, you can use only the Metric Threshold, Metric Absence, and Uptime Check conditions in your Stackdriver Monitoring alerting policies. In the Premium Tier, you can also use Metric Rate of Change, Group Aggregate Threshold, and Process Health.

In the Basic Tier, you can use only Email and Cloud Console Mobile App notifications in your Stackdriver Monitoring alerting policies. In the Premium Tier, you can also use SMS, PagerDuty, Webhooks, SNS, HipChat, Campfire, and Slack.

Frequently asked questions

How do I select my service tier?

Change your service tier in the billing page of your Stackdriver account. When you create a new Stackdriver account, it is in the Premium Tier for a 30-day free trial. After that, your account and the projects it monitors revert to the Basic Tier unless you upgrade. For more information about changing tiers, see Managing Service Tiers.

What if my project is not associated with a Stackdriver account?

Without a Stackdriver account, your project has the Basic Tier log allotment and retention period, and has access to Basic Tier services from Stackdriver Logging, Error Reporting, Debugger, and Trace. You cannot use Stackdriver Monitoring, upgrade to the Premium Tier, or sign up to accept overage charges.

How do I associate a Stackdriver account for my project?

With your project selected in the Cloud Platform Console, choose Stackdriver > Monitoring and follow the instructions to create a Stackdriver account. For more information, see Creating a Stackdriver account.

How much do I have to pay for the Premium Tier?

You can estimate the cost by looking at your current usage in the Stackdriver Resource Usage page and by putting those values into the Google Cloud Platform Pricing Calculator.

After the free trial expires, does my Stackdriver account change to the Basic Tier?

Yes. If you intend to upgrade, do it before your trial expires to avoid the risk of losing log entries when your logs allotment and retention period drop to the Basic Tier levels.

Can I have some Stackdriver accounts in the Premium Tier and others in the Basic Tier?

Yes.

Can I select which resources to monitor in my Stackdriver account?

No. All resources created in the projects within your Stackdriver account are monitored.

Can I change the service tier of individual projects in a Stackdriver account?

No. All the projects monitored by a single Stackdriver account share the account's service tier and other Stackdriver billing options. However, you can move projects to different Stackdriver accounts with different service tiers.

If I upgrade to the Premium Tier, can I later change back to the Basic Tier?

Yes. When you downgrade your account, you immediately lose access to Premium-only features and your logs are truncated to the shorter retention period.

Can I add custom and logs-based metrics to my Basic Tier account?

Yes. You must sign up to pay metric overage charges in your Basic Tier account.

What happens if I go over my allotments in the Premium Tier?

Premium Tier Stackdriver accounts are automatically billed for logs and metric overages. You do not lose any logs or metrics.

Log allotments are reset at the beginning of each monthly billing period. For example, if you go over your allotment on the last day of the month, then you'll have your full allotment back the next day.

Will I lose access to all my logs beyond the 5 GB Basic Tier limit?

See the example in Logs allotments.

I have a large volume of GCP logs in my project(s) that I do not use. I am concerned about charges for these logs. How do I avoid this?

If the GCP logs are classified as exempt, they will not count toward your allotment or cause overage charges. For more information, see Exempt and non-exempt logs. This is a subject that is being reviewed and may change.

Will services that send logs to my project receive an error when my allotment is exceeded?

No. Services that send log entries to your project cannot determine whether the entries were accepted, unless the service tries to read back the entries through the Stackdriver Logging API. Discarded entries will not be present, just as they are not visible in the Logs Viewer.

What about GCP features that are in Beta release?

GCP Beta features might be exempted from the pricing or other limitations of the service tiers. For more information, see the documentation for the Beta feature.
