x509 Certificate Input Plugin

This plugin provides information about X509 certificate accessible via local file or network connection.

Configuration

# Reads metrics from a SSL certificate
[[inputs.x509_cert]]
  ## List certificate sources
  sources = ["/etc/ssl/certs/ssl-cert-snakeoil.pem", "https://example.org:443"]

  ## Timeout for SSL connection
  # timeout = "5s"

  ## Pass a different name into the TLS request (Server Name Indication)
  ##   example: server_name = "myhost.example.org"
  # server_name = "myhost.example.org"

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
