This page provides details on the limits that apply to using Stackdriver Profiler.
Profiler API quotas and limits
The Profiler API quotas place limits on the number of API requests that the Profiler backend can support for a specific Google Cloud project. The quotas include limits on all of the following:
- Number of new deployments per day
- Number of update requests per minute
- Number of update requests per day
If you exceed a quota, the Profiler backend rejects the API request. For example, if the quota for the number of new deployments per day is 75 and if 80 new deployments are created in one day, then you won't collect profiling data for 5 of your deployments.
As a second example, if you have 10 deployments for a service that collects Heap and Wall time profiling, then the quota for the number of update requests per minute must be at least 20:
10 deployments x 2 profile types per deployment x 1 update request per profile type per minute = 20 update requests per minute (on average)
If this quota is less than 20, some profiles won't be transmitted successfully to the Profiler backend.
