Overview ¶
Package dns is a generated protocol buffer package.
It is generated from these files:
github.com/google/cloudprober/probes/dns/config.proto
It has these top-level messages:
ProbeConf
Package dns implements a DNS prober. It sends UDP DNS queries to a list of targets and reports statistics on queries sent, queries received, and latency experienced.
This prober uses the DNS library in /third_party/golang/dns/dns to construct, send, and receive DNS messages. Every message is sent on a different UDP port. Queries to each target are sent in parallel.

Types ¶
type Client ¶
type Client interface {
Exchange(*dns.Msg, string) (*dns.Msg, time.Duration, error)
SetReadTimeout(time.Duration)
}
Client provides a DNS client interface for required functionality. This makes it possible to mock.
type ClientImpl ¶
ClientImpl is a concrete DNS client that can be instantiated.
func (*ClientImpl) SetReadTimeout ¶
func (c *ClientImpl) SetReadTimeout(d time.Duration)
SetReadTimeout allows write-access to the underlying ReadTimeout variable.
type Probe ¶
type Probe struct {
// contains filtered or unexported fields
}
Probe holds aggregate information about all probe runs, per-target.
type ProbeConf ¶
type ProbeConf struct {
// Domain to use when making DNS queries
ResolvedDomain *string `protobuf:"bytes,1,opt,name=resolved_domain,json=resolvedDomain,def=www.google.com." json:"resolved_domain,omitempty"`
// Export stats after these many milliseconds
StatsExportIntervalMsec *int32 `` /* 138-byte string literal not displayed */
XXX_unrecognized []byte `json:"-"`
}
