Metrics

The @PLUGIN@ plugin exports several metrics which can give insights into the usage and performance of the code owners functionality.

Latency Metrics

add_change_message_on_add_reviewer: Latency for adding a change message with the owned path when a code owner is added as a reviewer.
compute_changed_files: Latency for computing changed files.
compute_file_status: Latency for computing the file status for one file.
compute_file_statuses: Latency for computing file statuses for all files in a change.
compute_owned_paths: Latency for computing file statuses.
compute_owned_paths: Latency for computing the files in a change that are owned by a user.
compute_patch_set_approvals: Latency for computing the approvals of the current patch set.
extend_change_message_on_post_review: Latency for extending the change message with the owned path when a code owner approval is applied.
get_auto_merge: Latency for getting the auto merge commit of a merge commit.
prepare_file_status_computation: Latency for preparing the file status computation.
prepare_file_status_computation_for_account: Latency for preparing the file status computation for an account.
resolve_code_owner_config: Latency for resolving a code owner config file.
resolve_code_owner_config_import: Latency for resolving an import of a code owner config file.
resolve_code_owner_config_imports: Latency for resolving all imports of a code owner config file.
run_code_owner_submit_rule: Latency for running the code owner submit rule.

code_owner_config_cache_reads_per_change: Number of code owner config cache reads per change.
code_owner_config_backend_reads_per_change: Number of code owner config backend reads per change.
load_code_owner_config: Latency for loading a code owner config file (read + parse).
parse_code_owner_config: Latency for parsing a code owner config file.
read_code_owner_config: Latency for reading a code owner config file.

count_code_owner_config_reads: Total number of code owner config reads from backend.
count_code_owner_config_cache_reads: Total number of code owner config reads from cache.
count_code_owner_submit_rule_errors: Total number of code owner submit rule errors.
- cause: The cause of the submit rule error.
count_code_owner_submit_rule_runs: Total number of code owner submit rule runs.
count_invalid_code_owner_config_files: Total number of failed requests caused by an invalid / non-parsable code owner config file.
- project: The name of the project that contains the invalid code owner config file.
- branch: The name of the branch that contains the invalid code owner config file.
- path: The path of the invalid code owner config file.
