DNS Query Input Plugin
The DNS plugin gathers dns query times in miliseconds - like Dig
Configuration:
# Query given DNS server and gives statistics
[[inputs.dns_query]]
## servers to query
servers = ["8.8.8.8"]
## Network is the network protocol name.
# network = "udp"
## Domains or subdomains to query.
# domains = ["."]
## Query record type.
## Possible values: A, AAAA, CNAME, MX, NS, PTR, TXT, SOA, SPF, SRV.
# record_type = "A"
## Dns server port.
# port = 53
## Query timeout in seconds.
# timeout = 2
Metrics:
- dns_query
- tags:
- server
- domain
- record_type
- result
- rcode
- fields:
- query_time_ms (float)
- result_code (int, success = 0, timeout = 1, error = 2)
- rcode_value (int)
- tags:
