Description Jump to heading

A resolvers section lists one or more DNS nameservers, to which the load balancer sends DNS queries. The show resolvers command lists the following information for each resolvers section that you’ve defined in your load balancer configuration:

Field	Displays the number of
`sent`	DNS requests sent to this group of nameservers
`snd_error`	Times there was an error sending the DNS query
`valid`	Valid DNS responses received from this group of nameservers
`update`	DNS responses used to update a server’s IP address
`cname`	CNAME responses
`cname_error`	CNAME errors returned from this group of nameservers
`any_err`	"Empty responses (i.e.
`nx`	Non-existent domain responses received from this group of nameservers
`timeout`	Times this group of nameservers did not answer in time
`refused`	Requests refused by this group of nameservers
`other`	Any other DNS errors
`invalid`	Invalid DNS responses (from a protocol point of view)
`too_big`	Responses that were too big to process
`truncated`	Responses that were truncated
`outdated`	Responses that arrived too late (after another nameserver)

Without any arguments, show resolvers returns information about all resolvers sections. You can filter this to show only a specific section by adding its name.
