Upgrading

From Graylog 1.x to 2.0.x

Removed configuration settings

Some settings, which have been deprecated in previous versions, have finally been removed from the Graylog configuration file.

Table 1. Removed configuration settings

Setting name	Replacement
mongodb_host	mongodb_uri
mongodb_port	mongodb_uri
mongodb_database	mongodb_uri
mongodb_useauth	mongodb_uri
mongodb_user	mongodb_uri
mongodb_password	mongodb_uri

Changed configuration defaults

For better consistency, the defaults of some configuration settings have been changed after the project has been renamed from Graylog2 to Graylog.

Table 2. Configuration defaults

Setting name	Old default	New default
elasticsearch_cluster_name	graylog2	graylog
elasticsearch_node_name	graylog2-server	graylog-server
elasticsearch_index_prefix	graylog2	graylog
mongodb_uri	mongodb://127.0.0.1/graylog2	mongodb://localhost/graylog

Changed prefixes for configuration override

In the past it was possible to override configuration settings in Graylog using environment variables or Java system properties with a specific prefix.

For better consistency, these prefixes have been changed after the project has been renamed from Graylog2 to Graylog.

Table 3. Configuration override prefixes

Override	Old prefix	New prefix	Example
Environment variables	GRAYLOG2_	GRAYLOG_	GRAYLOG_IS_MASTER
System properties	graylog2.	graylog.	graylog.is_master
