Andrew Newdigate d022ce8655 Add OpenTracing instrumentation for Action View Render events 
This change adds three new instrumentations, driven through rails
notifications: render_template.action_view,
render_collection.action_view and render_partial.action_view.

These can help developers understand why renders are taking a long
time which may in turn help them to improve their performance.

Configuration files Documentation

Note that most configuration files (config/*.*) committed into gitlab-ce will not be used for omnibus-gitlab. Configuration files committed into gitlab-ce are only used for development.

gitlab.yml

You can find most of GitLab configuration settings here.

mail_room.yml

This file is actually an YML wrapped inside an ERB file to enable templated values to be specified from gitlab.yml. mail_room loads this file first as an ERB file and then loads the resulting YML as its configuration.

resque.yml

This file is called resque.yml for historical reasons. We are NOT using Resque at the moment. It is used to specify Redis configuration values when a single database instance of Redis is desired.

Advanced Redis configuration files

In more advanced configurations of Redis key-value storage, it is desirable to separate the keys by lifecycle and intended use to ease provisioning and management of scalable Redis clusters.

These settings provide routing and other configuration data (such as sentinel, persistence policies, and other Redis customization) for connections to Redis single instances, Redis sentinel, and Redis clusters.

If desired, the routing URL provided by these settings can be used with:

  1. Unix Socket
    1. named socket for each Redis instance desired.
    2. database number for each Redis instance desired.
  2. TCP Socket
    1. host name or IP for each Redis instance desired
    2. TCP port number for each Redis instance desired
    3. database number for each Redis instance desired

Example URL attribute formats for GitLab Redis .yml configuration files

  • Unix Socket, default Redis database (0)
    • url: unix:/path/to/redis.sock
    • url: unix:/path/to/redis.sock?db=
  • Unix Socket, Redis database 44
    • url: unix:/path/to/redis.sock?db=44
    • url: unix:/path/to/redis.sock?extra=foo&db=44
  • TCP Socket for Redis on localhost, port 6379, database 33
    • url: redis://:mynewpassword@localhost:6379/33
  • TCP Socket for Redis on remote host myserver, port 6379, database 33
    • url: redis://:mynewpassword@myserver:6379/33

redis.cache.yml

If configured, redis.cache.yml overrides the resque.yml settings to configure the Redis database instance used for Rails.cache and other volatile non-persistent data which enhances the performance of GitLab. Settings here can be overridden by the environment variable GITLAB_REDIS_CACHE_CONFIG_FILE which provides an alternate location for configuration settings.

The order of precedence for the URL used to connect to the Redis instance used for cache is:

  1. URL from a configuration file pointed to by the GITLAB_REDIS_CACHE_CONFIG_FILE environment variable
  2. URL from redis.cache.yml
  3. URL from a configuration file pointed to by the GITLAB_REDIS_CONFIG_FILE environment variable
  4. URL from resque.yml
  5. redis://localhost:6380

The order of precedence for all other configuration settings for cache are selected from only the first of the following files found (if a setting is not provided in an earlier file, the remainder of the files are not searched):

  1. the configuration file pointed to by the GITLAB_REDIS_CACHE_CONFIG_FILE environment variable
  2. the configuration file redis.cache.yml
  3. the configuration file pointed to by the GITLAB_REDIS_CONFIG_FILE environment variable
  4. the configuration file resque.yml

redis.queues.yml

If configured, redis.queues.yml overrides the resque.yml settings to configure the Redis database instance used for clients of ::Gitlab::Redis::Queues. These queues are intended to be the foundation of reliable inter-process communication between modules, whether on the same host node, or within a cluster. The primary clients of the queues are SideKiq, Mailroom, CI Runner, Workhorse, and push services. Settings here can be overridden by the environment variable GITLAB_REDIS_QUEUES_CONFIG_FILE which provides an alternate location for configuration settings.

The order of precedence for the URL used to connect to the Redis instance used for queues is:

  1. URL from a configuration file pointed to by the GITLAB_REDIS_QUEUES_CONFIG_FILE environment variable
  2. URL from redis.queues.yml
  3. URL from a configuration file pointed to by the GITLAB_REDIS_CONFIG_FILE environment variable
  4. URL from resque.yml
  5. redis://localhost:6381

The order of precedence for all other configuration settings for queues are selected from only the first of the following files found (if a setting is not provided in an earlier file, the remainder of the files are not searched):

  1. the configuration file pointed to by the GITLAB_REDIS_QUEUES_CONFIG_FILE environment variable
  2. the configuration file redis.queues.yml
  3. the configuration file pointed to by the GITLAB_REDIS_CONFIG_FILE environment variable
  4. the configuration file resque.yml

redis.shared_state.yml

If configured, redis.shared_state.yml overrides the resque.yml settings to configure the Redis database instance used for clients of ::Gitlab::Redis::SharedState such as session state, and rate limiting. Settings here can be overridden by the environment variable GITLAB_REDIS_SHARED_STATE_CONFIG_FILE which provides an alternate location for configuration settings.

The order of precedence for the URL used to connect to the Redis instance used for shared_state is:

  1. URL from a configuration file pointed to by the GITLAB_REDIS_SHARED_STATE_CONFIG_FILE environment variable
  2. URL from redis.shared_state.yml
  3. URL from a configuration file pointed to by the GITLAB_REDIS_CONFIG_FILE environment variable
  4. URL from resque.yml
  5. redis://localhost:6382

The order of precedence for all other configuration settings for shared_state are selected from only the first of the following files found (if a setting is not provided in an earlier file, the remainder of the files are not searched):

  1. the configuration file pointed to by the GITLAB_REDIS_SHARED_STATE_CONFIG_FILE environment variable
  2. the configuration file redis.shared_state.yml
  3. the configuration file pointed to by the GITLAB_REDIS_CONFIG_FILE environment variable
  4. the configuration file resque.yml
