Zonemaster Backend is configured in
/etc/zonemaster/backend_config.ini (Linux) or
/usr/local/etc/zonemaster/backend_config.ini (FreeBSD). Following
Installation instructions will create the file with factory settings.
Restart the zm-rpcapi and zm-testagent daemons to load the changes
made to the backend_config.ini file.
The backend_config.ini file uses a file format in the INI family that is
described in detail here.
Repeating a key name in one section is forbidden.
Each section in backend_config.ini is documented below.
In addition to the configuration file, some settings can configured using environement variables.
Available keys: enable_add_batch_job, enable_add_api_user.
Boolean value to enable the enable_add_batch_job methods of the API.
Accepted values: yes (or true) or no (or false),
default to yes (enabled).
Boolean value to enable the add_api_user method of the API.
Accepted values: yes (or true) or no (or false),
default to no (disabled).
Available keys : engine, user, password, database_name,
database_host, polling_interval.
Specifies what database engine to use.
The value must be one of the following, case-insensitively: MySQL,
PostgreSQL and SQLite.
This table declares what value to use for each supported database engine.
| Database Engine | Value |
|---|---|
| MariaDB | MySQL |
| MySQL | MySQL |
| PostgreSQL | PostgreSQL |
| SQLite | SQLite |
A strictly positive decimal number. Max 5 and 3 digits in the integer and fraction components respectively.
Time in seconds between database lookups by Test Agent.
Default value: 0.5.
Available keys : host, port, user, password, database.
An LDH domain name or IP address.
The host name of the machine on which the MySQL server is running.
The port the MySQL server is listening on.
Default value: 3306.
If MYSQL.host is set to localhost (but neither 127.0.0.1 nor ::1),
then the value of the [MYSQL.port] property is discarded as the driver
connects using a UNIX socket (see the DBD::mysql documentation).
An ASCII-only MariaDB unquoted identifier. Max length 80 characters.
The name of the user with sufficient permission to access the database.
A string of US ASCII printable characters.
The first character must be neither space nor <.
Max length 100 characters.
The password of the configured user.
A US ASCII-only MariaDB unquoted identifier. Max length 64 characters.
The name of the database to use.
Available keys : host, port, user, password, database.
An LDH domain name or IP address.
The host name of the machine on which the PostgreSQL server is running.
The port the PostgreSQL server is listening on.
Default value: 5432.
A US ASCII-only PostgreSQL identifier. Max length 63 characters.
The name of the user with sufficient permission to access the database.
A string of US ASCII printable characters.
The first character must be neither space nor <.
Max length 100 characters.
The password of the configured user.
A US ASCII-only PostgreSQL identifier. Max length 63 characters.
The name of the database to use.
Available keys : database_file.
An absolute path.
The full path to the SQLite main database file.
The LANGUAGE section has one key, locale.
A string matching one of the following descriptions:
- A space separated list of one or more
locale tagswhere each tag matches the regular expression/^[a-z]{2}_[A-Z]{2}$/. - The empty string. Deprecated, remove the LANGUAGE.locale entry or specify LANGUAGE.locale = en_US instead.
It is an error to repeat the same locale tag.
If the locale key is empty or absent, the locale tag value
"en_US" is set by default.
The two first characters of a locale tag are intended to be an
ISO 639-1 two-character language code and the two last characters
are intended to be an ISO 3166-1 alpha-2 two-character country code.
A locale tag is a locale setting for the available translation
of messages without ".UTF-8", which is implied.
Removing a language from the configuration file just blocks that
language from being allowed. If there are more than one locale tag
(with different country codes) for the same language, then
all those must be removed to block that language.
English is the Zonemaster default language, but it can be blocked
from being allowed by RPC-API by including some locale tag in the
configuration, but none starting with language code for English ("en").
The default installation and configuration supports the following languages.
| Language | Locale tag value | Language code | Locale value used |
|---|---|---|---|
| Danish | da_DK | da | da_DK.UTF-8 |
| English | en_US | en | en_US.UTF-8 |
| Spanish | es_ES | es | es_ES.UTF-8 |
| Finnish | fi_FI | fi | fi_FI.UTF-8 |
| French | fr_FR | fr | fr_FR.UTF-8 |
| Norwegian | nb_NO | nb | nb_NO.UTF-8 |
| Swedish | sv_SE | sv | sv_SE.UTF-8 |
Setting in the default configuration file:
locale = da_DK en_US es_ES fi_FI fr_FR nb_NO sv_SE
If a new locale tag is added to the configuration then the equivalent
MO file should be added to Zonemaster-Engine at the correct place so
that gettext can retrieve it, or else the added locale tag will not
add any actual language support. The MO file should be created for the
language code of the locale tag (see the table above), not the entire
locale tag. E.g. if the locale configuration key includes "sv_SE" then
a MO file for "sv" should be included in the installation.
Use of MO files based on the entire locale tag is deprecated.
See the Zonemaster-Engine share directory for the existing PO files that are converted to MO files during installation. (Here we should have a link to documentation instead.)
Each locale set in the configuration file, including the implied ".UTF-8", must also be installed or activate on the system running the RPCAPI daemon for the translation to work correctly.
An LDH domain name or IP address.
The host name of the machine on which the StatsD receiver is running.
Leave unspecified to disable the metrics.
Note that this feature requires the Net::Statsd module to be installed.
The port the StatsD receiver is listening on.
Default value: 8125.
The PUBLIC PROFILES and PRIVATE PROFILES sections together define the available profiles.
Keys in both sections are profile names, and values are absolute file system
paths to profile JSON files. The key must conform to the character limitation
specified for profile name as specified in the API document
Profile name section. Keys that only differ in case are considered to be equal.
Keys must not be duplicated between or within the sections, and the key
default must not be present in the PRIVATE PROFILES section.
There is a default profile that is special. It is always available even
if not specified. If it is not explicitly mapped to a profile JSON file, it is implicitly
mapped to the Zonemaster Engine default profile.
The Zonemaster Engine default profile is created by what is specified in Zonemaster::Engine::Profile and by loading the Default JSON profile file.
Each profile JSON file contains a (possibly empty) set of overrides to the Zonemaster Engine default profile. Specifying a profile JSON file that contains a complete set of profile data is equivalent to specifying a profile JSON file with only the parts that differ from the Zonemaster Engine default profile.
Specifying a profile JSON file that contains no profile data is equivalent to specifying a profile JSON file containing the entire Zonemaster Engine default profile.
The ZONEMASTER section has several keys :
- max_zonemaster_execution_time
- number_of_processes_for_frontend_testing
- number_of_processes_for_batch_testing
- lock_on_queue
- age_reuse_previous_test
A strictly positive integer. Max length 5 digits.
Time in seconds before reporting an unfinished test as failed.
Default value: 600.
A strictly positive integer. Max length 5 digits.
Number of processes allowed to run in parallel (added with
number_of_processes_for_batch_testing).
Default value: 20.
Despite its name, this key does not limit the number of process used by the
frontend, but is used in combination of
number_of_processes_for_batch_testing.
A non-negative integer. Max length 5 digits.
Number of processes allowed to run in parallel (added with
number_of_processes_for_frontend_testing).
Default value: 20.
Despite its name, this key does not limit the number of process used by any
batch pool of tests, but is used in combination of
number_of_processes_for_frontend_testing.
A non-negative integer. Max length 5 digits.
A label to associate a test to a specific Test Agent.
Default value: 0.
A strictly positive integer. Max length 5 digits.
The shelf life of a test in seconds after its creation.
Default value: 600.
If a new test is requested for the same zone name and parameters within the shelf life of a previous test result, that test result is reused. Otherwise a new test request is enqueued.
