DNS Query Input Plugin

The DNS plugin gathers dns query times in miliseconds - like Dig

Configuration:

# Sample Config:
[[inputs.dns_query]]
  ## servers to query
  servers = ["8.8.8.8"] # required

  ## Domains or subdomains to query. "." (root) is default
  domains = ["."] # optional

  ## Query record type. Posible values: A, AAAA, ANY, CNAME, MX,  NS, PTR, SOA, SPF, SRV, TXT. Default is "NS"
  record_type = "A" # optional

  ## Dns server port. 53 is default
  port = 53 # optional

  ## Query timeout in seconds. Default is 2 seconds
  timeout = 2 # optional

For querying more than one record type make:

[[inputs.dns_query]]
  domains = ["mjasion.pl"]
  servers = ["8.8.8.8", "8.8.4.4"]
  record_type = "A"

[[inputs.dns_query]]
  domains = ["mjasion.pl"]
  servers = ["8.8.8.8", "8.8.4.4"]
  record_type = "MX"

Tags:

• server
• domain
• record_type
