This document lists the quotas and system limits that apply to Cloud Monitoring.
- Quotas have default values, but you can typically request adjustments.
- System limits are fixed values that can't be changed.
Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.
The Cloud Quotas system does the following:
- Monitors your consumption of Google Cloud products and services
- Restricts your consumption of those resources
- Provides a way to request changes to the quota value and automate quota adjustments
In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.
Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.
For more information, see the Cloud Quotas overview.To adjust most quotas, use the Google Cloud console. For more information, see Request a quota adjustment.
There are also system limits on Monitoring resources. System limits can't be changed.
Monitoring API quotas and limits
Category | Maximum value |
---|---|
Limits to API usage |
To find the API quotas and limits, do one of the following:
|
Lifetime of API page tokens | 24 hours |
Data retention
Metric data points older than the retention period are deleted from time series.
Category | Value |
---|---|
Retention of data points for some Google Cloud services, including most
metrics within the following categories:
|
24 months1 |
Retention of all other Google Cloud metrics | 6 weeks |
Lifetime of API page tokens | 24 hours |
Resource groups
Category | Value |
---|---|
Number of resource groups per metrics scope | 500 |
Maximum number of groups included in an email report1 | 10 |
1 When you configure Cloud Monitoring email reports, you can request information on utilization of your resource groups. Due to a limitation in the email reporter, the generated reports include information for only 10 groups.
Limits for synthetic monitors
Category | Value |
---|---|
Uptime checks per metrics scope * | 100 |
Maximum number of ICMP pings per public uptime check | 3 |
Synthetic monitors per metrics scope | 100† |
