telemetry.metrics_enabled

Controls whether telemetry metrics are collected or not.

telemetry.otel_exporter_otlp_metrics_protocol

The OLTP transport protocol.

telemetry.otel_exporter_otlp_metrics_endpoint

Endpoint metric signals are sent to.

telemetry.otel_exporter_otlp_metrics_network_namespace

(Linux only) Network namespace to use when sending data to the metrics endpoint.

telemetry.otel_exporter_otlp_metrics_certificates

The trusted certificate to use when verifying a server's TLS credentials.

telemetry.otel_exporter_otlp_metrics_client_key

Client's private key in PEM format.

telemetry.otel_exporter_otlp_metrics_client_certificates

Client certificate/chain trust for clients private key in PEM format.

telemetry.otel_exporter_otlp_metrics_min_tls

Minimum TLS version to use for metrics.

telemetry.otel_exporter_otlp_metrics_max_tls

Maximum TLS version to use for metrics.

telemetry.otel_exporter_otlp_metrics_cipher

Current list of TLS 1.2 ciphers to use for metrics. The current default is:

ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:
ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:
ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES256-CCM:ECDHE-ECDSA-AES128-CCM:
DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-CCM:
DHE-RSA-AES128-CCM:DHE-RSA-CHACHA20-POLY1305

telemetry.otel_exporter_otlp_metrics_cipher_suite

Current list of TLS 1.3 ciphers to use for metrics. The current default is:

 TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_CCM_SHA256

telemetry.otel_exporter_otlp_metrics_headers

Key-value pairs to be used as headers associated with HTTP requests.

telemetry.otel_exporter_otlp_metrics_secret_headers

Name of a secret, that contains the sensitive data for metrics headers. The data content and format depends on the secret provider implementation provided with system variable telemetry.secret_provider.

telemetry.otel_exporter_otlp_metrics_compression

Compression used by exporter

telemetry.otel_exporter_otlp_metrics_timeout

Time in milliseconds the OLTP exporter waits for each batch export.

telemetry.metrics_reader_frequency_1

Mandatory. Defines the interval in seconds (f1) between meter evaluations for meters with a frequency less than or equal to the interval, f1. For example:

SELECT * from performance_schema.setup_meters WHERE FREQUENCY <= telemetry.metrics_reader_frequency_1

            

telemetry.metrics_reader_frequency_2

Optional. Defines the interval in seconds (f2) between meter evaluations for meters with a frequency greater than the interval, f1. For example, if f1 and f2 are defined:

SELECT * from performance_schema.setup_meters WHERE FREQUENCY <= telemetry.metrics_reader_frequency_1
            

and, every f2 seconds:

SELECT * from performance_schema.setup_meters 
      WHERE FREQUENCY > telemetry.metrics_reader_frequency_1 
      AND FREQUENCY <= metrics_reader_frequency_2;
 
            

telemetry.metrics_reader_frequency_3

Optional. Defines the interval in seconds (f3) between meter evaluations for meters with a frequency greater than the interval, f2. For example, if f1, f2, and f3 are defined:

SELECT * from performance_schema.setup_meters WHERE FREQUENCY <= telemetry.metrics_reader_frequency_1
            

and, every f2 seconds:

SELECT * from performance_schema.setup_meters 
      WHERE FREQUENCY > telemetry.metrics_reader_frequency_1 
      AND FREQUENCY <= metrics_reader_frequency_2;
 
            

and, every f3 seconds:

SELECT * from performance_schema.setup_meters WHERE FREQUENCY > telemetry.metrics_reader_frequency_2;
