+ =item B<RestoreAffinityPolicy> I<AllCPUs>|I<Restore>
+
+ Reading data from CPU has side-effect: collectd process's CPU affinity mask
+ changes. After reading data is completed, affinity mask needs to be restored.
+ This option allows to set restore policy.
+
+ B<AllCPUs> (the default): Restore the affinity by setting affinity to any/all
+ CPUs.
+
+ B<Restore>: Save affinity using sched_getaffinity() before reading data and
+ restore it after.
+
+ On some systems, sched_getaffinity() will fail due to inconsistency of the CPU
+ set size between userspace and kernel. In these cases plugin will detect the
+ unsuccessful call and fail with an error, preventing data collection.
+ Most of configurations does not need to save affinity as Collectd process is
+ allowed to run on any/all available CPUs.
+
+ If you need to save and restore affinity and get errors like 'Unable to save
+ the CPU affinity', setting 'possible_cpus' kernel boot option may also help.

+ The C<write_stackdriver> plugin writes metrics to the

+
+ This plugin supports two authentication methods: When configured, credentials
+ are read from the JSON credentials file specified with B<CredentialFile>.
+ Alternatively, when running on
+ I<Google Compute Engine> (GCE), an I<OAuth> token is retrieved from the
+ I<metadata server> and used to authenticate to GCM.

+ =item B<CredentialFile> I<file>
+
+ Path to a JSON credentials file holding the credentials for a GCP service

+ If B<CredentialFile> is not specified, the plugin uses I<Application Default
+ Credentials>. That means which credentials are used depends on the environment:

+ freely when creating a new project. The I<Project Number> is a 12-digit decimal
+ number. You can look up both on the I<Developer Console>.
+
+ This setting is optional. If not set, the project ID is read from the
+ credentials file or determined from the GCE's metadata service.
+
+ =item B<Email> I<Email> (GCE only)
+
+ Choses the GCE I<Service Account> used for authentication.
+
+ Each GCE instance has a C<default> I<Service Account> but may also be

+ the permissions of services running on the GCE instance to the required
+ minimum. The I<write_stackdriver plugin> requires the
