Redis Configuration

Configuration of the Redis that Icinga writes to.

port	Optional. Redis port. Defaults to 6379. Specify 6380 if using the icingadb-redis package.
password	Optional. The password to use.
tls	Optional. Whether to use TLS.
cert	Optional. Path to TLS client certificate.
key	Optional. Path to TLS private key.
ca	Optional. Path to TLS CA certificate.
insecure	Optional. Whether not to verify the peer.

Database Configuration

Configuration of the database used by Icinga DB.

Option	Description
type	Optional. Either mysql (default) or pgsql.
host	Required. Database host or absolute Unix socket path.
port	Required. Database port.
database	Required. Database database.
user	Required. Database username.
password	Required. Database password.
tls	Optional. Whether to use TLS.
cert	Optional. Path to TLS client certificate.
key	Optional. Path to TLS private key.
ca	Optional. Path to TLS CA certificate.
insecure	Optional. Whether not to verify the peer.

Logging Configuration

Configuration of the logging component used by Icinga DB.

Option	Description
level	Optional. Specifies the default logging level. Can be set to fatal, error, warn, info or debug. Defaults to info.
output	Optional. Configures the logging output. Can be set to console (stderr) or systemd-journald. If not set, logs to systemd-journald when running under systemd, otherwise stderr.
interval	Optional. Interval for periodic logging defined as duration string. Defaults to "20s".
options	Optional. Map of component name to logging level in order to set a different logging level for each component instead of the default one. See logging components for details.

Logging Components

Component	Description
config-sync	Config object synchronization between Redis and MySQL.
database	Database connection status and queries.
dump-signals	Dump signals received from Icinga.
heartbeat	Icinga heartbeats received through Redis.
high-availability	Manages responsibility of Icinga DB instances.
history-sync	Synchronization of history entries from Redis to MySQL.
overdue-sync	Calculation and synchronization of the overdue status of checkables.
redis	Redis connection status and queries.
retention	Deletes historical data that exceed their configured retention period.
runtime-updates	Runtime updates of config objects after the initial config synchronization.

Duration String

A duration string is a sequence of decimal numbers and a unit suffix, such as "20s". Valid units are "ms", "s", "m" and "h".

Retention

By default, no historical data is deleted, which means that the longer the data is retained, the more disk space is required to store it. History retention is an optional feature that allows you to limit the number of days that historical data is available for each history category. There are separate options for the full history tables used to display history information in the web interface and SLA tables which store the minimal information required for SLA reporting, allowing to keep this information for longer with a smaller storage footprint.

Option	Description
history-days	Optional. Number of days to retain historical data for all history categories. Use options in order to enable retention only for specific categories or to override the retention days configured here.
sla-days	Optional. Number of days to retain historical data for SLA reporting.
options	Optional. Map of history category to number of days to retain its data. Available categories are acknowledgement, comment, downtime, flapping, notification, sla and state.
