Redis is a key-value database in a similar vein to memcache but the dataset is non-volatile. Redis additionally provides native support for atomically manipulating and querying data structures such as lists and sets. The dataset is stored entirely in memory and periodically flushed to disk.
Enable or disable redis-cluster. This config can only be set pre-deploy.
Set the number of databases. The default database is DB 0. You can select a different one on a per-connection basis using SELECT <dbid> where dbid is a number between 0 and 'databases'-1.
Specify the Redis server verbosity level. Choices are: - debug (a lot of information, useful for development/testing); - verbose (many rarely useful info, but not a mess like the debug level); - notice (moderately verbose, what you want in production probably); - warning (only very important / critical messages are logged).
Used by the nrpe subordinate charms. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.
A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup
Require clients to issue AUTH <PASSWORD> before processing any other commands.
Accept connections on the specified port.
DEPRECATED. Use snap-http-proxy and snap-https-proxy model configuration settings. HTTP/HTTPS web proxy for Snappy to use when accessing the snap store.
DEPRECATED. Use snap-store-proxy model configuration setting. The address of a Snap Store Proxy to use for snaps e.g. http://snap-proxy.example.com
How often snapd handles updates for installed snaps. The default (an empty string) is 4x per day. Set to "max" to check once per month based on the charm deployment date. You may also set a custom string as described in the 'refresh.timer' section here: https://forum.snapcraft.io/t/system-options/87
If non-zero, use SO_KEEPALIVE to send TCP ACKs to clients in absence of communication. This is useful to detect dead peers and to take the connection alive from the point of view of network quipment in the middle. The specified value is in seconds.
Close the connection after a client is idle for N seconds (0 to disable).
