Learn about configurations >

• beats_port | int

  Default: 5044

  TCP port for Beats input when relation is joined

• channel | string

  Default: 2/stable

  Snap channel used to install/refresh the graylog snap.

  This option has no effect when a valid graylog.snap resource is attached.

• elasticsearch_cluster_name | string

  If the elastic search cluster name is not passed in the relation set it here.

• index_replicas | int

  Number of Elasticsearch replicas used per index in this index set.

• index_retention_count | int

  Default: 6

  Maximum number of indices to keep before deleting the oldest ones

• index_rotation_msg_count | int

  Default: 20000000

  When rotation strategy is "msg_count", maximum number of documents in an index before it gets rotated

• index_rotation_period | string

  Default: P7D

  When rotation strategy is "time" based, rotation period (ISO8601 Duration) - How long an index gets written to before it is rotated.

• index_rotation_size | int

  Default: 1073741824

  When rotation strategy is "size" based, maximum size of an index before it gets rotated. Defaults to 1073741824 (1GB).

• index_rotation_strategy | string

  Default: time

  Type of rotation strategy ("time" based, "size" based, no. messages "msg_count").

• index_shards | int

  Default: 2

  Number of Elasticsearch shards used per index in this index set. Set this to '0' to let the charm automatically calculate based on how many Elasticsearch units.

• jvm_heap_size | string

  Default: 1G

  JVM Heap memory size (default 1G)

• log_inputs | string

  YAML-formatted list of log inputs. First input gets passed through relations. Any input not defined here will be removed unless it is prefixed with "Custom" in the title.

• nagios_context | string

  Default: juju

  Used by the nrpe-external-master subordinate charm. 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.

• nagios_servicegroups | string

  A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup.

• nagios_uncommitted_crit | int

  Default: 2048

  Number of journaled uncommitted messages that will generate a nagios CRITICAL alert

• nagios_uncommitted_warn | int

  Default: 1024

  Number of journaled uncommitted messages that will generate a nagios WARN

• rest_transport_uri | string

  Default: http://0.0.0.0:9001/api/

  This setting is only required when external access to the Graylog nodes is required to pass through a proxy/load balancer. This address is used by the Web Interface to access the REST API.

  For Graylog 2, the proxy should connect back to the Graylog node on port 9001 (the default).

  For Graylog 3, this setting is ignored. web_endpoint_uri is used as the universal proxy setting.

  • If the ip address 0.0.0.0 is specified, the charm will attempt to deduct the network interface that is used for connections to the default gateway and use the associated ip address.

• snapd_refresh | string

  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

• web_endpoint_uri | string

  This setting is only required when external access to the Graylog nodes is required to pass through a proxy/load balancer. This address is used by the Web Interface to download secondary assets (JavaScript/CSS/etc). This setting should be the public address of the proxy, which will direct traffic to Graylog.

  For Graylog 2, the proxy should connect back to the address set in 'web_listen_uri' *. The 'web_listen_uri' will be used as the default value if this config is left blank.

  For Graylog 3, the proxy should connect back to the Graylog node on port 9000 (the default). If this config is left blank, the charm will attempt to determine the correct network interfance *.

  • If the ip address 0.0.0.0 is specified, the charm will attempt to deduct the network interface that is used for connections to the default gateway and use the associated ip address.

• web_listen_uri | string

  Default: http://0.0.0.0:9000/

  For Graylog 2, this URI specifies which IP and port Graylog will LISTEN to for the Web Interface.

  For Graylog 3, this setting is ignored. The Web Interface and REST API listen on the same IP and port.
