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"
