There is an ongoing effort to standardize TLS options across plugins. When possible, plugins will provide the standard settings described below. With the exception of the advanced configuration available TLS settings will be documented in the sample configuration.
Client Configuration
For client TLS support we have the following options:
## Root certificates for verifying server certificates encoded in PEM format.
# tls_ca = "/etc/telegraf/ca.pem"
## The public and private keypairs for the client encoded in PEM format. May
## contain intermediate certificates.
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Skip TLS verification.
# insecure_skip_verify = false
Server Configuration
The server TLS configuration provides support for TLS mutual authentication:
## Set one or more allowed client CA certificate file names to
## enable mutually authenticated TLS connections.
# tls_allowed_cacerts = ["/etc/telegraf/clientca.pem"]
## Add service certificate and key.
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
Advanced Configuration
For plugins using the standard server configuration you can also set several advanced settings. These options are not included in the sample configuration for the interest of brevity.
## Define list of allowed ciphers suites. If not defined the default ciphers
## supported by Go will be used.
## ex: tls_cipher_suites = [
## "TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305",
## "TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305",
## "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256",
## "TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256",
## "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384",
## "TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384",
## "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256",

## "TLS_RSA_WITH_AES_128_CBC_SHA256",
## "TLS_RSA_WITH_AES_128_CBC_SHA",
## "TLS_RSA_WITH_AES_256_CBC_SHA"
## ]
# tls_cipher_suites = []
## Minimum TLS version that is acceptable.
# tls_min_version = "TLS10"
## Maximum SSL/TLS version that is acceptable.
# tls_max_version = "TLS13"
