x509 Certificate Input Plugin

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

When using a UDP address as a certificate source, the server must support DTLS.

Configuration

# Reads metrics from a SSL certificate
[[inputs.x509_cert]]
  ## List certificate sources, support wildcard expands for files
  ## Prefix your entry with 'file://' if you intend to use relative paths
  sources = ["tcp://example.org:443", "https://influxdata.com:443",
            "udp://127.0.0.1:4433", "/etc/ssl/certs/ssl-cert-snakeoil.pem",
            "/etc/mycerts/*.mydomain.org.pem", "file:///path/to/*.pem"]

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

  ## Pass a different name into the TLS request (Server Name Indication).
  ## This is synonymous with tls_server_name, and only one of the two
  ## options may be specified at one time.
  ##   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"
  # tls_server_name = "myhost.example.org"

  ## Set the proxy URL
  # use_proxy = true
  # proxy_url = "http://localhost:8888"
