# This is the configuration file for Icinga DB.

# Connection configuration for the database to which Icinga DB synchronizes monitoring data.
# This is also the database used in Icinga DB Web to view and work with the data.
# In high availability setups, all Icinga DB instances must write to the same database.
database:
  # Database type. Either 'mysql' for MySQL or 'pgsql' for PostgreSQL.
  # Defaults to 'mysql'.
#  type: mysql

  # Database host or absolute Unix socket path.
  host: localhost

  # Database port. By default, the MySQL or PostgreSQL port, depending on the database type.
#  port:

  # Database name.
  database: icingadb

  # Database user.
  user: icingadb

  # Database password.
  password: CHANGEME

  # List of low-level database options that can be set to influence some Icinga DB internal default behaviours.
  # Do not change the defaults if you don't have to!
#  options:
    # Maximum number of connections Icinga DB is allowed to open in parallel to the database.
    # By default, Icinga DB is allowed to open up to "16" connections whenever necessary.
    # Setting this to a number less than or equal to "-1" allows Icinga DB to open an unlimited number of connections.
    # However, it is not possible to set this option to "0".
#    max_connections: 16

    # Maximum number of queries allowed to connect to a single database table simultaneously.
    # By default, Icinga DB is allowed to execute up to "8" queries of any kind, e.g. INSERT,UPDATE,DELETE
    # concurrently on a given table.
    # It is not possible to set this option to a smaller number than "1".
#    max_connections_per_table: 8

    # Maximum number of placeholders Icinga DB is allowed to use for a single SQL statement.
    # By default, Icinga DB uses up to "8192" placeholders when necessary, which showed the
    # best performance in terms of execution time and parallelism in our tests.
    # It is not possible to set this option to a smaller number than "1".
#    max_placeholders_per_statement: 8192

    # Maximum number of rows Icinga DB is allowed to select, delete, update or insert in a single transaction.
    # By default, Icinga DB selects,deletes,updates,inserts up to "8192" rows in a single transaction, which showed
    # the best performance in terms of execution time and parallelism in our tests.
    # It is not possible to set this option to a smaller number than "1".
#    max_rows_per_transaction: 8192

    # Enforce Galera cluster nodes to perform strict cluster-wide causality checks before executing
    # specific SQL queries determined by the number you provided.
    # Note: You can only set this option to a number "0 - 15".
    # Defaults to 7.

# Connection configuration for the Redis® server where Icinga 2 writes its configuration, state and history items.
# This is the same connection as configured in the 'icingadb' feature of the corresponding Icinga 2 node.
# High availability setups require a dedicated Redis® server per Icinga 2 node and
# therefore a dedicated Icinga DB instance that connects to it.
redis:
  # Host name or address, or absolute Unix socket path.
  host: localhost

  # TCP port.
  # Defaults to '6380' as the Redis® open source server provided by the 'icingadb-redis' package listens on that port.
#  port: 6380

  # Authentication password.

# Icinga DB logs its activities at various severity levels and any errors that occur either
# on the console or in systemd's journal. The latter is used automatically when running under systemd.
# In any case, the default log level is 'info'.
#logging:
  # Default logging level. Can be set to 'fatal', 'error', 'warn', 'info' or 'debug'.
  # If not set, defaults to 'info'.
#  level: info

  # Logging output. Can be set to 'console' (stderr) or 'systemd-journald'.
  # If not set, logs to systemd-journald when running under systemd, otherwise stderr.
#  output:

  # Interval for periodic logging defined as duration string.
  # A duration string is a sequence of decimal numbers and a unit suffix, such as "20s".
  # Valid units are "ms", "s", "m", "h".
  # Defaults to "20s".
#  interval: 20s

# Retention is an optional feature to limit the number of days that historical data is available,
# as no historical data is deleted by default.
#retention:
  # Number of days to retain full historical data. By default, historical data is retained forever.
#  history-days:

  # Number of days to retain historical data for SLA reporting. By default, it is retained forever.
#  sla-days:

  # Interval for periodically cleaning up the historical data, defined as a duration string.
  # A duration string is a sequence of decimal numbers and a unit suffix, such as "20s".
  # Valid units are "ms", "s", "m", "h".
  # Defaults to "1h".
#  interval: 1h

  # Number of old historical entries a single query can delete in a "DELETE FROM ... LIMIT count" manner.
  # By default, this is limited to 5000 entries.
#  count: 5000

  # Map of history category to number of days to retain its data in order to
