377/669] Tracking of custom events GitLab Performance Monitoring is now able to track custom events not directly related to application performance. These events include the number of tags pushed, repositories created, builds registered, etc. The use of these events is to get a better overview of how a GitLab instance is used and how that may affect performance. For example, a large number of Git pushes may have a negative impact on the underlying storage engine. Events are stored in the "events" measurement and are not prefixed with "rails_" or "sidekiq_", this makes it easier to query events with the same name triggered from different parts of the application. All events being stored in the same measurement also makes it easier to downsample data. Currently the following events are tracked: * Creating repositories * Removing repositories * Changing the default branch of a repository * Pushing a new tag * Removing an existing tag * Pushing a commit (along with the branch being pushed to) * Pushing a new branch * Removing an existing branch * Importing a repository (along with the URL we're importing) * Forking a repository (along with the source/target path) * CI builds registered (and when no build could be found) * CI builds being updated * Rails and Sidekiq exceptions Fixes gitlab-org/gitlab-ce#13720 --- CHANGELOG | 1 + app/models/repository.rb | 20 +++++++ app/workers/repository_fork_worker.rb | 4 ++ app/workers/repository_import_worker.rb | 4 ++ doc/monitoring/performance/influxdb_schema.md | 9 +++ lib/ci/api/builds.rb | 8 +++ lib/gitlab/metrics.rb | 9 +++ lib/gitlab/metrics/metric.rb | 9 ++- lib/gitlab/metrics/rack_middleware.rb | 4 ++ lib/gitlab/metrics/sidekiq_middleware.rb | 4 ++ lib/gitlab/metrics/transaction.rb | 21 ++++++- spec/lib/gitlab/metrics/metric_spec.rb | 18 ++++++ .../gitlab/metrics/rack_middleware_spec.rb | 9 +++ .../gitlab/metrics/sidekiq_middleware_spec.rb | 24 +++++++- spec/lib/gitlab/metrics/transaction_spec.rb | 57 +++++++++++++++++++ spec/lib/gitlab/metrics_spec.rb | 24 ++++++++ 16 files changed, 219 insertions(+), 6 deletions(-) diff --git a/CHANGELOG b/CHANGELOG index 837e9e27aba..4986ffd7351 100644 --- a/CHANGELOG +++ b/CHANGELOG @@ -16,6 +16,7 @@ v 8.11.0 (unreleased) - API: List access requests, request access, approve, and deny access requests to a project or a group. !4833 - Use long options for curl examples in documentation !5703 (winniehell) - Remove magic comments (`# encoding: UTF-8`) from Ruby files. !5456 (winniehell) + - GitLab Performance Monitoring can now track custom events such as the number of tags pushed to a repository - Add support for relative links starting with ./ or / to RelativeLinkFilter (winniehell) - Ignore URLs starting with // in Markdown links !5677 (winniehell) - Fix CI status icon link underline (ClemMakesApps) diff --git a/app/models/repository.rb b/app/models/repository.rb index e56bac509a4..916843dabdd 100644 --- a/app/models/repository.rb +++ b/app/models/repository.rb @@ -391,6 +391,8 @@ class Repository expire_exists_cache expire_root_ref_cache expire_emptiness_caches + + repository_event(:create_repository) end # Runs code just before a repository is deleted. @@ -407,6 +409,8 @@ class Repository expire_root_ref_cache expire_emptiness_caches expire_exists_cache + + repository_event(:remove_repository) end # Runs code just before the HEAD of a repository is changed. @@ -414,6 +418,8 @@ class Repository # Cached divergent commit counts are based on repository head expire_branch_cache expire_root_ref_cache + + repository_event(:change_default_branch) end # Runs code before pushing (= creating or removing) a tag. @@ -421,12 +427,16 @@ class Repository expire_cache expire_tags_cache expire_tag_count_cache + + repository_event(:push_tag) end # Runs code before removing a tag. def before_remove_tag expire_tags_cache expire_tag_count_cache + + repository_event(:remove_tag) end def before_import @@ -443,6 +453,8 @@ class Repository # Runs code after a new commit has been pushed. def after_push_commit(branch_name, revision) expire_cache(branch_name, revision) + + repository_event(:push_commit, branch: branch_name) end # Runs code after a new branch has been created. @@ -450,11 +462,15 @@ class Repository expire_branches_cache expire_has_visible_content_cache expire_branch_count_cache + + repository_event(:push_branch) end # Runs code before removing an existing branch. def before_remove_branch expire_branches_cache + + repository_event(:remove_branch) end # Runs code after an existing branch has been removed. @@ -1059,4 +1075,8 @@ class Repository def keep_around_ref_name(sha) "refs/keep-around/#{sha}" end + + def repository_event(event, tags = {}) + Gitlab::Metrics.add_event(event, { path: path_with_namespace }.merge(tags)) + end end diff --git a/app/workers/repository_fork_worker.rb b/app/workers/repository_fork_worker.rb index d69d6037053..61ed1c38ac4 100644 --- a/app/workers/repository_fork_worker.rb +++ b/app/workers/repository_fork_worker.rb @@ -5,6 +5,10 @@ class RepositoryForkWorker sidekiq_options queue: :gitlab_shell def perform(project_id, forked_from_repository_storage_path, source_path, target_path) + Gitlab::Metrics.add_event(:fork_repository, + source_path: source_path, + target_path: target_path) + project = Project.find_by_id(project_id) unless project.present?
