== `getdns_server_mon`
|
||||
|
||||
`getdns_server_mon` is a collection of DNS server tests. The tests examine
|
||||
both server function and server capability.
|
||||
|
||||
`get_server_mon` can optionally be run in Monitoring mode. In this mode,
|
||||
the tool output is modified to enable it to function as a plugin for
|
||||
popular monitoring systems such as https://www.icinga.org[Icinga],
|
||||
http://naemon.github.io/[Naemon], http://www.nagios.org[Nagios],
|
||||
http://www.shinken-monitoring.org/[Shinken], http://sensuapp.org/[Sensu]

||||

|

Tests:
|

lookup [<name> [<type>]] Check lookup on server
|
||||
keepalive <timeout-ms> [<name> [<type>]]
|
||||
Check server support for EDNS0 keepalive in
|
||||
TCP or TLS connections
|
||||
Timeout of 0 is off.
|
||||
OOOR Check whether server delivers responses out of
|
||||
query order on a TCP or TLS connection
|
||||
qname-min Check whether server supports QNAME minimisation
|
||||
rtt [warn-ms,crit-ms] [<name> [<type>]]
|
||||
Check if server round trip time exceeds
|
||||
thresholds (default 250,500)
|
||||
|
||||
dnssec-validate Check whether server does DNSSEC validation
|
||||
|
||||
tls-auth [<name> [<type>]] Check authentication of TLS server
|
||||
If both a SPKI pin and authentication name are
|
||||
provided, both must authenticate for this test
|
||||
to pass.
|
||||
tls-cert-valid [warn-days,crit-days] [<name> [type]]
|
||||
Check server certificate validity, report
|
||||
warning or critical if days to expiry at
|
||||
or below thresholds (default 14,7).
|
||||
tls-padding <blocksize> [<name> [<type>]]
|
||||
Check server support for EDNS0 padding in TLS
|
||||
Special blocksize values are 0 = off,
|
||||
1 = sensible default.
|
||||
tls-1.3 Check whether server supports TLS 1.3
|
||||
|
||||
Enabling monitoring mode ensures output messages and exit statuses conform
|
||||
to the requirements of monitoring plugins (www.monitoring-plugins.org).
|
||||
----
|
||||
|
||||
Note that the server must currently be specified with an IPv4 or an IPv6 address.
|
||||
|
||||
=== The tests
|
||||
|
||||
Several tests take optional name and RR type parameters. If these are not supplied,
|
||||
default values of `getdnsapi.net` and `AAAA` are used. If the lookup returns no
|
||||
answering records, `getdns_server_mon` reports a status of WARNING.

| Check a name lookup succeeds.
|

| UDP with TCP fallback
|
||||
|
||||
| `keepalive`
|
||||
| See if the server supports EDNS0 keepalive in TCP or TLS
|
||||
connections. Specify a non-zero timeout to set the keepalive timeout
|
||||
in milliseconds, or 0 to disable it.
|
||||
| TCP
|
||||
|
||||
| `OOOR`
|
||||
| Out Of Order Responses. See if the server will send responses to
|
||||
multiple queries in a single TCP or TLS connection in a different
|

order to the order of queries.
|

|

This test is currently experimental, and may give false negative results.

If thresholds are not specified, defaults of 500ms (critical) and 250ms (warning) are used.
|

|

|
||||
|
||||
|`tls-auth`
|
||||
| Check if a TLS lookup authenticates successfully. You must specify
|
||||
either a SPKI pin, an authentication name, or both. If you supply
|
||||
both, both must authenticate for the test to succeed.
|
||||
| TLS
|
||||
|

|`tls-cert-valid`
|

| Check the server certificate against warning and critical days to

| TLS
|
||||
|
||||
|`tls-padding`
|
||||
| Does the server support EDNS0 padding? Specify a non-zero blocksize to set
|

the padding. A padding size of 1 specifies padding of a sensible default size.
|
||||
| TLS
|
||||
|
||||
|`tls-1.3`
|
||||
| Does the server support TLS 1.3? To enable this test,

`getdns_server_mon` must be compiled with OpenSSL v1.1.1 or later.

|

|
||||
== Description
|
||||
|
||||
The tests examine both server function and server capability.
|
||||
|
||||
`get_server_mon` can optionally be run in Monitoring mode. In this mode,
|
||||
the tool output is modified to enable it to function as a plugin for
|
||||
popular monitoring systems such as https://www.icinga.org[Icinga],
|
||||
http://naemon.github.io/[Naemon], http://www.nagios.org[Nagios],
|
||||
http://www.shinken-monitoring.org/[Shinken], http://sensuapp.org/[Sensu]
|
||||
and others.
|
||||
|
||||
== Options
|
||||
|
||||
-M|--monitoring:: Make output suitable for monitoring tools
|
||||
-E|--fail-on-dns-errors:: Fail on DNS error (NXDOMAIN, SERVFAIL)
|
||||
-u|--udp:: Use UDP transport
|
||||
-t|--tcp:: Use TCP transport
|
||||
-T|--tls:: Use TLS transport
|
||||
-S|--strict-usage-profile:: Use strict profile (require authentication)
|
||||
-K|--spki-pin <spki-pin>:: SPKI pin for TLS connections (can repeat)
|
||||
-v|--verbose:: Increase output verbosity
|
||||
-D|--debug:: Enable debugging output
|
||||
-V|--version:: Report GetDNS version
|
||||
|
||||
=== Test parameters
|
||||
lookup [<name> [<type>]]:: Check lookup on server
|
||||
keepalive <timeout-ms> [<name> [<type>]]::
|
||||
Check server support for EDNS0 keepalive in
|
||||
TCP or TLS connections
|
||||
Timeout of 0 is off.
|
||||
OOOR:: Check whether server delivers responses out of
|
||||
query order on a TCP or TLS connection
|
||||
qname-min:: Check whether server supports QNAME minimisation
|
||||
rtt [warn-ms,crit-ms] [<name> [<type>]]::
|
||||
Check if server round trip time exceeds
|
||||
thresholds (default 250,500)
|
||||
|
||||
dnssec-validate:: Check whether server does DNSSEC validation
|
||||
|
||||
tls-auth [<name> [<type>]]:: Check authentication of TLS server
|
||||
If both a SPKI pin and authentication name are
|
||||
provided, both must authenticate for this test
|
||||
to pass.
|
||||
tls-cert-valid [warn-days,crit-days] [<name> [type]]::
|
||||
Check server certificate validity, report
|
||||
warning or critical if days to expiry at
|
||||
or below thresholds (default 14,7).
|
||||
tls-padding <blocksize> [<name> [<type>]]::
|
||||
Check server support for EDNS0 padding in TLS
|
||||
Special blocksize values are 0 = off,
|
||||
1 = sensible default.
|
||||
tls-1.3:: Check whether server supports TLS 1.3
|
||||
|
||||
Enabling monitoring mode ensures output messages and exit statuses conform
|
||||
to the requirements of monitoring plugins (www.monitoring-plugins.org).
|
||||
|
||||
Note that the server must currently be specified with an IPv4 or an IPv6 address.
|
||||
|
||||
=== The tests
|
||||
|
||||
Several tests take optional name and RR type parameters. If these are not supplied,
|
||||
default values of `getdnsapi.net` and `AAAA` are used. If the lookup returns no
|
||||
answering records, `getdns_server_mon` reports a status of WARNING.

|
||||
| Test name | Test description | Default connection type
|
||||
| `lookup`
|
||||
| Check a name lookup succeeds.
|
||||
| UDP with TCP fallback
|
||||
|
||||
| `keepalive`
|
||||
| See if the server supports EDNS0 keepalive in TCP or TLS
|
||||
connections. Specify a non-zero timeout to set the keepalive timeout
|
||||
in milliseconds, or 0 to disable it.
|
||||
| TCP
|
||||
|
||||
| `OOOR`
|
||||
| Out Of Order Responses. See if the server will send responses to
|
||||
multiple queries in a single TCP or TLS connection in a different
|
||||
order to the order of queries.
|
||||
|
||||
This test is currently experimental, and may give false negative results.
|
||||
| TCP
|
||||
|
||||
| `qname-min`
|
||||
| Does the server support QNAME minimisation?
|
||||
| UDP with TCP fallback
|
||||
|
||||
|`rtt`
|
||||
| Check a lookup round trip time exceeds warning and critical levels in milliseconds.
|
||||
If thresholds are not specified, defaults of 500ms (critical) and 250ms (warning) are used.
|
||||
| UDP with TCP fallback
|
||||
|
||||
|`dnssec-validate`
|
||||
| See if the server is doing DNSSEC validation.
|
||||
| UDP with TCP fallback
|
||||
|
||||
|`tls-auth`
|
||||
| Check if a TLS lookup authenticates successfully. You must specify
|
||||
either a SPKI pin, an authentication name, or both. If you supply
|
||||
both, both must authenticate for the test to succeed.
|
||||
| TLS
|
||||
|
||||
|`tls-cert-valid`
|
||||
| Check the server certificate against warning and critical days to
|
||||
expiry. If thresholds are not specified, defaults of 7 days
|
||||
(critical) and 14 days (warning) are used.
|
||||
| TLS
|
||||
|
||||
|`tls-padding`
|
||||
| Does the server support EDNS0 padding? Specify a non-zero blocksize to set
|
||||
the padding. A padding size of 1 specifies padding of a sensible default size.
|
||||
| TLS
|
||||
|
||||
|`tls-1.3`
|
||||
| Does the server support TLS 1.3? To enable this test,
|
||||
`getdns_server_mon` must be compiled with OpenSSL v1.1.1 or later.
|
||||
|
||||
This test is currently experimental, and may give false negative results.
