Kener Documentation

DNS monitors query records for a host and compare returned values to your expected values.

Minimum setup

Configure:

host
lookupRecord (default A)
matchType (ANY or ALL, default ANY)
at least one expected value in values

nameServer is optional (leave blank for resolver defaults).

Configuration fields

Field	Type	Default	Notes
`host`	`string`	—	Required
`nameServer`	`string`	`""`	Optional override
`lookupRecord`	`string`	`A`	Required
`matchType`	`ANY\|ALL`	`ANY`	Required
`values`	`string[]`	`[]`	Required (non-empty values)

Match behavior

ANY: monitor is UP when at least one expected value is present
ALL: monitor is UP only when all expected values are present

Normalization rules

Before comparison, values are normalized by runtime logic:

lowercased
trailing . removed
trimmed whitespace

Example

{
    "type": "DNS",
    "type_data": {
        "host": "example.com",
        "lookupRecord": "A",
        "matchType": "ANY",
        "values": ["93.184.216.34"]
    }
}
