Log system

GitLab has an advanced log system where everything is logged, so you can analyze your instance using various system log files. In addition to system log files, GitLab Enterprise Edition provides Audit Events. Find more about them in Audit Events documentation.

System log files are typically plain text in a standard log file format. This guide talks about how to read and use these system log files.

`production_json.log`

This file lives in /var/log/gitlab/gitlab-rails/production_json.log for Omnibus GitLab packages or in /home/git/gitlab/log/production_json.log for installations from source. When GitLab is running in an environment other than production, the corresponding log file is shown here.

It contains a structured log for Rails controller requests received from GitLab, thanks to Lograge. Note that requests from the API are logged to a separate file in api_json.log.

Each line contains a JSON line that can be ingested by services like Elasticsearch and Splunk. Line breaks have been added to this example for legibility:

{
  "method":"GET",
  "path":"/gitlab/gitlab-foss/issues/1234",
  "format":"html",
  "controller":"Projects::IssuesController",
  "action":"show",
  "status":200,
  "time":"2017-08-08T20:15:54.821Z",
  "params":[{"key":"param_key","value":"param_value"}],
  "remote_ip":"18.245.0.1",
  "user_id":1,
  "username":"admin",
  "queue_duration_s":0.0,
  "gitaly_calls":16,
  "gitaly_duration_s":0.16,
  "redis_calls":115,
  "redis_duration_s":0.13,
  "correlation_id":"O1SdybnnIq7",
  "cpu_s":17.50,
  "db_duration_s":0.08,
  "view_duration_s":2.39,
  "duration_s":20.54
}

This example was a GET request for a specific issue. Each line also contains performance data, with times in milliseconds:

duration_s: total time taken to retrieve the request
queue_duration_s: total time that the request was queued inside GitLab Workhorse
view_duration_s: total time taken inside the Rails views
db_duration_s: total time to retrieve data from PostgreSQL
redis_duration_s: total time to retrieve data from Redis
cpu_s: total time spent on CPU
gitaly_duration_s: total time taken by Gitaly calls
gitaly_calls: total number of calls made to Gitaly
redis_calls: total number of calls made to Redis

User clone and fetch activity using HTTP transport appears in this log as action: git_upload_pack.

In addition, the log contains the originating IP address, (remote_ip),the user's ID (user_id), and username (username).

NOTE: Note: Starting with GitLab 12.5, if an error occurs, an exception field is included with class, message, and backtrace. Previous versions included an error field instead of exception.class and exception.message. For example:

{
  "method": "GET",
  "path": "/admin",
  "format": "html",
  "controller": "Admin::DashboardController",
  "action": "index",
  "status": 500,
  "time": "2019-11-14T13:12:46.156Z",
  "params": [],
  "remote_ip": "127.0.0.1",

  "correlation_id":"O1SdybnnIq7",
  "cpu_s":17.50,
  "db_duration_s":0.08,
  "view_duration_s":2.39,
  "duration_s":20.54
  "exception.class": "NameError",
  "exception.message": "undefined local variable or method `adsf' for #<Admin::DashboardController:0x00007ff3c9648588>",
  "exception.backtrace": [

    "app/controllers/application_controller.rb:444:in `set_locale'",
    "ee/lib/gitlab/jira/middleware.rb:19:in `call'"
  ]
}

`production.log`

This file lives in /var/log/gitlab/gitlab-rails/production.log for Omnibus GitLab packages or in /home/git/gitlab/log/production.log for installations from source. (When GitLab is running in an environment other than production, the corresponding log file is shown here.)

It contains information about all performed requests. You can see the URL and type of request, IP address, and what parts of code were involved to service this particular request. Also, you can see all SQL requests performed, and how much time each took. This task is more useful for GitLab contributors and developers. Use part of this log file when you're reporting bugs. For example:

Started GET "/gitlabhq/yaml_db/tree/master" for 168.111.56.1 at 2015-02-12 19:34:53 +0200
Processing by Projects::TreeController#show as HTML
  Parameters: {"project_id"=>"gitlabhq/yaml_db", "id"=>"master"}

  ... [CUT OUT]

  Rendered layouts/_page.html.haml (32.9ms)
Completed 200 OK in 166ms (Views: 117.4ms | ActiveRecord: 27.2ms)

In this example, the server processed an HTTP request with URL /gitlabhq/yaml_db/tree/master from IP 168.111.56.1 at 2015-02-12 19:34:53 +0200. The request was processed by Projects::TreeController.

`api_json.log`

Introduced in GitLab 10.0.

This file lives in /var/log/gitlab/gitlab-rails/api_json.log for Omnibus GitLab packages, or in /home/git/gitlab/log/api_json.log for installations from source.

It helps you see requests made directly to the API. For example:

{
  "time":"2018-10-29T12:49:42.123Z",
  "severity":"INFO",
  "duration":709.08,
  "db":14.59,
  "view":694.49,
  "status":200,
  "method":"GET",
  "path":"/api/v4/projects",
  "params":[{"key":"action","value":"git-upload-pack"},{"key":"changes","value":"_any"},{"key":"key_id","value":"secret"},{"key":"secret_token","value":"[FILTERED]"}],
  "host":"localhost",
  "remote_ip":"::1",
  "ua":"Ruby",
  "route":"/api/:version/projects",
  "user_id":1,
  "username":"root",
  "queue_duration":100.31,
  "gitaly_calls":30,
  "gitaly_duration":5.36
}

This entry shows an access to an internal endpoint to check whether an associated SSH key can download the project in question via a git fetch or git clone. In this example, we see:

duration: total time in milliseconds taken to retrieve the request
queue_duration: total time in milliseconds that the request was queued inside GitLab Workhorse
method: The HTTP method used to make the request
path: The relative path of the query
params: Key-value pairs passed in a query string or HTTP body. Sensitive parameters (such as passwords and tokens) are filtered out.
ua: The User-Agent of the requester

`application.log`

This file lives in /var/log/gitlab/gitlab-rails/application.log for Omnibus GitLab packages or in /home/git/gitlab/log/application.log for installations from source.

It helps you discover events happening in your instance such as user creation, project removing and so on. For example:

October 06, 2014 11:56: User "Administrator" (admin@example.com) was created
October 06, 2014 11:56: Documentcloud created a new project "Documentcloud / Underscore"
October 06, 2014 11:56: Gitlab Org created a new project "Gitlab Org / Gitlab Ce"
October 07, 2014 11:25: User "Claudie Hodkiewicz" (nasir_stehr@olson.co.uk)  was removed
October 07, 2014 11:25: Project "project133" was removed

`application_json.log`

Introduced in GitLab 12.7.

This file lives in /var/log/gitlab/gitlab-rails/application_json.log for Omnibus GitLab packages or in /home/git/gitlab/log/application_json.log for installations from source.

It contains the JSON version of the logs in application.log like the example below:

{
  "severity":"INFO",
  "time":"2020-01-14T13:35:15.466Z",
  "correlation_id":"3823a1550b64417f9c9ed8ee0f48087e",
  "message":"User \"Administrator\" (admin@example.com) was created"
}
{
  "severity":"INFO",
  "time":"2020-01-14T13:35:15.466Z",
  "correlation_id":"78e3df10c9a18745243d524540bd5be4",
  "message":"Project \"project133\" was removed"
}

`integrations_json.log`

This file lives in /var/log/gitlab/gitlab-rails/integrations_json.log for Omnibus GitLab packages or in /home/git/gitlab/log/integrations_json.log for installations from source.

It contains information about integrations activities such as Jira, Asana, and Irker services. It uses JSON format like the example below:

{
  "severity":"ERROR",
  "time":"2018-09-06T14:56:20.439Z",
  "service_class":"JiraService",
  "project_id":8,
  "project_path":"h5bp/html5-boilerplate",
  "message":"Error sending message",

  "message":"Successfully posted",
  "client_url":"http://jira.example.com"
}

`kubernetes.log`

Introduced in GitLab 11.6.

This file lives in /var/log/gitlab/gitlab-rails/kubernetes.log for Omnibus GitLab packages or in /home/git/gitlab/log/kubernetes.log for installations from source.

It logs information related to the Kubernetes Integration including errors during installing cluster applications on your GitLab managed Kubernetes clusters.

Each line contains a JSON line that can be ingested by services like Elasticsearch and Splunk. Line breaks have been added to the following example for clarity:

{
  "severity":"ERROR",
  "time":"2018-11-23T15:14:54.652Z",
  "exception":"Kubeclient::HttpError",
  "error_code":401,

  "exception":"Kubeclient::HttpError",
  "error_code":null,
  "service":"Clusters::Applications::InstallService",
  "app_id":2,
  "project_ids":[19],
  "group_ids":[],
  "message":"SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate)"
}

`git_json.log`

This file lives in /var/log/gitlab/gitlab-rails/git_json.log for Omnibus GitLab packages or in /home/git/gitlab/log/git_json.log for installations from source.

NOTE: Note: After 12.2, this file was renamed from githost.log to git_json.log and stored in JSON format.

GitLab has to interact with Git repositories, but in some rare cases something can go wrong, and in this case you will know what exactly happened. This log file contains all failed requests from GitLab to Git repositories. In the majority of cases this file will be useful for developers only. For example:

{
   "severity":"ERROR",
   "time":"2019-07-19T22:16:12.528Z",
   "correlation_id":"FeGxww5Hj64",
   "message":"Command failed [1]: /usr/bin/git --git-dir=/Users/vsizov/gitlab-development-kit/gitlab/tmp/tests/gitlab-satellites/group184/gitlabhq/.git --work-tree=/Users/vsizov/gitlab-development-kit/gitlab/tmp/tests/gitlab-satellites/group184/gitlabhq merge --no-ff -mMerge branch 'feature_conflict' into 'feature' source/feature_conflict\n\nerror: failed to push some refs to '/Users/vsizov/gitlab-development-kit/repositories/gitlabhq/gitlab_git.git'"
}

`audit_json.log`

This file lives in /var/log/gitlab/gitlab-rails/audit_json.log for Omnibus GitLab packages or in /home/git/gitlab/log/audit_json.log for installations from source.

Changes to group or project settings are logged to this file. For example:

{
  "severity":"INFO",
  "time":"2018-10-17T17:38:22.523Z",
  "author_id":3,
  "entity_id":2,
  "entity_type":"Project",
  "change":"visibility",
  "from":"Private",
  "to":"Public",
  "author_name":"John Doe4",
  "target_id":2,
  "target_type":"Project",
  "target_details":"namespace2/project2"
}

`sidekiq.log`

This file lives in /var/log/gitlab/gitlab-rails/sidekiq.log for Omnibus GitLab packages or in /home/git/gitlab/log/sidekiq.log for installations from source.

GitLab uses background jobs for processing tasks which can take a long time. All information about processing these jobs are written down to this file. For example:

2014-06-10T07:55:20Z 2037 TID-tm504 ERROR: /opt/bitnami/apps/discourse/htdocs/vendor/bundle/ruby/1.9.1/gems/redis-3.0.7/lib/redis/client.rb:228:in `read'
2014-06-10T18:18:26Z 14299 TID-55uqo INFO: Booting Sidekiq 3.0.0 with redis options {:url=>"redis://localhost:6379/0", :namespace=>"sidekiq"}

Instead of the format above, you can opt to generate JSON logs for Sidekiq. For example:

{
  "severity":"INFO",
  "time":"2018-04-03T22:57:22.071Z",
  "queue":"cronjob:update_all_mirrors",
  "args":[],
  "class":"UpdateAllMirrorsWorker",
  "retry":false,
  "queue_namespace":"cronjob",
  "jid":"06aeaa3b0aadacf9981f368e",
  "created_at":"2018-04-03T22:57:21.930Z",
  "enqueued_at":"2018-04-03T22:57:21.931Z",
  "pid":10077,
  "message":"UpdateAllMirrorsWorker JID-06aeaa3b0aadacf9981f368e: done: 0.139 sec",
  "job_status":"done",
  "duration":0.139,
  "completed_at":"2018-04-03T22:57:22.071Z",
  "db_duration":0.05,
  "db_duration_s":0.0005,
  "gitaly_duration":0,
  "gitaly_calls":0
}

For Omnibus GitLab installations, add the configuration option:

sidekiq['log_format'] = 'json'

For source installations, edit the gitlab.yml and set the Sidekiq log_format configuration option:

  ## Sidekiq
  sidekiq:
    log_format: json

`sidekiq_client.log`

Introduced in GitLab 12.9.

This file lives in /var/log/gitlab/gitlab-rails/sidekiq_client.log for Omnibus GitLab packages or in /home/git/gitlab/log/sidekiq_client.log for installations from source.

This file contains logging information about jobs before they are start being processed by Sidekiq, for example before being enqueued.

This logfile follows the same structure as sidekiq.log, so it will be structured as JSON if you've configured this for Sidekiq as mentioned above.

`gitlab-shell.log`

This file lives in /var/log/gitlab/gitaly/gitlab-shell.log for Omnibus GitLab packages or in /home/git/gitaly/gitlab-shell.log for installations from source.

NOTE: Note: For GitLab 12.5 and earlier, the file lives in /var/log/gitlab/gitlab-shell/gitlab-shell.log.

GitLab Shell is used by GitLab for executing Git commands and provide SSH access to Git repositories. For example:

I, [2015-02-13T06:17:00.671315 #9291]  INFO -- : Adding project root/example.git at </var/opt/gitlab/git-data/repositories/root/dcdcdcdcd.git>.

User clone/fetch activity using SSH transport appears in this log as executing git command <gitaly-upload-pack....

`current`

This file lives in /var/log/gitlab/gitaly/current and is produced by runit. runit is packaged with Omnibus and a brief explanation of its purpose is available in the omnibus documentation. Log files are rotated, renamed in unix timestamp format and gzip-compressed (e.g. @1584057562.s).

`unicorn_stderr.log`

This file lives in /var/log/gitlab/unicorn/unicorn_stderr.log for Omnibus GitLab packages or in /home/git/gitlab/log/unicorn_stderr.log for installations from source.

Unicorn is a high-performance forking Web server which is used for serving the GitLab application. You can look at this log if, for example, your application does not respond. This log contains all information about the state of Unicorn processes at any given time.

I, [2015-02-13T06:14:46.680381 #9047]  INFO -- : Refreshing Gem list

This structured log file records internal activity in the mail_room gem. Its name and path are configurable, so the name and path may not match the above.

Reconfigure Logs

Reconfigure log files live in /var/log/gitlab/reconfigure for Omnibus GitLab packages. Installations from source don't have reconfigure logs. A reconfigure log is populated whenever gitlab-ctl reconfigure is run manually or as part of an upgrade.

Reconfigure logs files are named according to the UNIX timestamp of when the reconfigure was initiated, such as 1509705644.log

`sidekiq_exporter.log` and `web_exporter.log`

If Prometheus metrics and the Sidekiq Exporter are both enabled, Sidekiq will start a Web server and listen to the defined port (default: 8082). Access logs will be generated in /var/log/gitlab/gitlab-rails/sidekiq_exporter.log for Omnibus GitLab packages or in /home/git/gitlab/log/sidekiq_exporter.log for installations from source.

If Prometheus metrics and the Web Exporter are both enabled, Unicorn/Puma will start a Web server and listen to the defined port (default: 8083). Access logs will be generated in /var/log/gitlab/gitlab-rails/web_exporter.log for Omnibus GitLab packages or in /home/git/gitlab/log/web_exporter.log for installations from source.

`database_load_balancing.log` (PREMIUM ONLY)

Introduced in GitLab 12.3.

Contains details of GitLab's Database Load Balancing. It's stored at:

`elasticsearch.log`

Introduced in GitLab 12.6.

This file lives in /var/log/gitlab/gitlab-rails/elasticsearch.log for Omnibus GitLab packages or in /home/git/gitlab/log/elasticsearch.log for installations from source.

It logs information related to the Elasticsearch Integration including errors during indexing or searching Elasticsearch.

Each line contains a JSON line that can be ingested by services like Elasticsearch and Splunk. Line breaks have been added to the following example line for clarity:

{
  "severity":"DEBUG",
  "time":"2019-10-17T06:23:13.227Z",
  "correlation_id":null,
  "message":"redacted_search_result",
  "class_name":"Milestone",
  "id":2,
  "ability":"read_milestone",
  "current_user_id":2,
  "query":"project"
}

`exceptions_json.log`

Introduced in GitLab 12.6.

This file lives in /var/log/gitlab/gitlab-rails/exceptions_json.log for Omnibus GitLab packages or in /home/git/gitlab/log/exceptions_json.log for installations from source.

It logs the information about exceptions being tracked by Gitlab::ErrorTracking which provides a standard and consistent way of processing rescued exceptions.

Each line contains a JSON line that can be ingested by Elasticsearch. For example:

{
  "severity": "ERROR",
  "time": "2019-12-17T11:49:29.485Z",
  "correlation_id": "AbDVUrrTvM1",

`geo.log`

Introduced in 9.5.

Geo stores structured log messages in a geo.log file. For Omnibus installations, this file is at /var/log/gitlab/gitlab-rails/geo.log.

This file contains information about when Geo attempts to sync repositories and files. Each line in the file contains a separate JSON entry that can be ingested into. For example, Elasticsearch or Splunk.

For example:

{"severity":"INFO","time":"2017-08-06T05:40:16.104Z","message":"Repository update","project_id":1,"source":"repository","resync_repository":true,"resync_wiki":true,"class":"Gitlab::Geo::LogCursor::Daemon","cursor_delay_s":0.038}

This message shows that Geo detected that a repository update was needed for project 1.

Registry Logs

For Omnibus installations, Container Registry logs reside in /var/log/gitlab/registry/current.

NGINX Logs

For Omnibus installations, NGINX logs reside in:

/var/log/gitlab/nginx/gitlab_access.log contains a log of requests made to GitLab.
/var/log/gitlab/nginx/gitlab_error.log contains a log of NGINX errors for GitLab.
/var/log/gitlab/nginx/gitlab_pages_access.log contains a log of requests made to Pages static sites.
/var/log/gitlab/nginx/gitlab_pages_error.log contains a log of NGINX errors for Pages static sites.
/var/log/gitlab/nginx/gitlab_registry_access.log contains a log of requests made to the Container Registry.
/var/log/gitlab/nginx/gitlab_registry_error.log contains a log of NGINX errors for the Container Regsitry.

Below is the default GitLab NGINX access log format:

$remote_addr - $remote_user [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent"
