COREDNS-ERRORS(7) CoreDNS Plugins COREDNS-ERRORS(7)

errors - enables error logging.

Any errors encountered during the query processing will be printed to standard output. The errors of particular type can be consolidated and printed once per some period of time.

This plugin can only be used once per Server Block.

The basic syntax is:

errors

Extra knobs are available with an expanded syntax:

errors {
    consolidate DURATION REGEXP
}

Option consolidate allows collecting several error messages matching the regular expression REGEXP during DURATION. After the DURATION since receiving the first such message, the consolidated message will be printed to standard output, e.g.

2 errors like '^read udp .* i/o timeout$' occurred in last 30s

Multiple consolidate options with different DURATION and REGEXP are allowed. In case if some error message corresponds to several defined regular expressions the message will be associated with the first appropriate REGEXP.

For better performance, it's recommended to use the ^ or $ metacharacters in regular expression when filtering error messages by prefix or suffix, e.g. ^failed to .*, or .* timeout$.

Use the whoami to respond to queries in the example.org domain and Log errors to standard output.

example.org {
    whoami
    errors
}

Use the forward to resolve queries via 8.8.8.8 and print consolidated error messages for errors with suffix " i/o timeout" or with prefix "Failed to ".

. {
    forward . 8.8.8.8
    errors {
        consolidate 5m ".* i/o timeout$"
        consolidate 30s "^Failed to .+"
    }
}
