Stackdriver Config

CustomConfig

Custom instance configuration overrides. Provides a way to customize metrics/logs.

FieldTypeDescriptionRequired
dimensionsmap<string, string>

(Optional) Collection of tag names and tag expressions to include in the instance. Conflicts are resolved by the tag name by overriding previously supplied values.

No

PluginConfig

next id: 15

FieldTypeDescriptionRequired
max_log_batch_size_in_bytesint32

Optional. Allows configuration of the size of the LogWrite request. The size is in bytes, so that it allows for better performance. Default is 4MB. The size of one log entry within LogWrite request is approx 1Kb.

No
log_report_durationDuration

Optional. Allows configuration of the time between calls out to the stackdriver logging service to report buffered LogWrite request. Customers can choose to report more aggressively by keeping shorter report interval if needed. Default is 10s.

No
enable_audit_logbool

Optional. Controls whether to export audit log.

No
destination_service_namestring

Optional. FQDN of destination service that the request routed to, e.g. productpage.default.svc.cluster.local. If not provided, request host header will be used instead

No
enable_mesh_edges_reportingbool

Optional. Controls whether or not to export mesh edges to a mesh edges service. This is disabled by default.

No
mesh_edges_reporting_durationDuration

Optional. Allows configuration of the time between calls out to the mesh edges service to report NEW edges. The minimum configurable duration is 10s. NOTE: This option ONLY configures the intermediate reporting of novel edges. Once every 10m, all edges observed in that 10m window are reported and the local cache is cleared. The default duration is 1m. Any value greater than 10m will result in reporting every 10m.

No
max_peer_cache_sizeint32

maximum size of the peer metadata cache. A long lived proxy that connects with many transient peers can build up a large cache. To turn off the cache, set this field to a negative value.

No
disable_host_header_fallbackbool

Optional: Disable using host header as a fallback if destination service is not available from the controlplane. Disable the fallback if the host header originates outsides the mesh, like at ingress.

No
max_edges_batch_sizeint32

Optional. Allows configuration of the number of traffic assertions to batch into a single request. Default is 100. Max is 1000.

No
disable_http_size_metricsbool

Optional. Allows disabling of reporting of the request and response size metrics for HTTP traffic. Defaults to false (request and response size metrics are enabled).

No
enable_log_compressionBoolValue

Optional. Allows enabling log compression for stackdriver access logs.

No
access_loggingAccessLogging

Optional. Controls what type of logs to export..

No
custom_log_configCustomConfig

(Optional) Collection of tag names and tag expressions to include in the logs. Conflicts are resolved by the tag name by overriding previously supplied values. Does not apply to audit logs. See https://istio.io/latest/docs/tasks/observability/metrics/customize-metrics/#use-expressions-for-values for more details about the expression language.

No
metric_expiry_durationDuration

Optional. Controls the metric expiry duration. If a metric time series is not updated for the given duration, it will be purged from time series cache as well as metric reporting. If this is not set or set to 0, time series will never be expired. This option is useful to avoid unbounded metric label explodes proxy memory.

No
disable_server_access_loggingbool

Optional. Controls whether to export server access log. This is deprecated in favor of AccessLogging enum.

No

PluginConfig.AccessLogging

Types of Access logs to export. Does not affect audit logging.
