# Monitoring GitHub imports >**Note:** Available since [GitLab 10.2][14731]. The GitHub importer exposes various Prometheus metrics that you can use to monitor the health and progress of the importer. ## Import Duration Times | Name | Type | |------------------------------------------|-----------| | `github_importer_total_duration_seconds` | histogram | This metric tracks the total time spent (in seconds) importing a project (from project creation until the import process finishes), for every imported project. The name of the project is stored in the `project` label in the format `namespace/name` (e.g. `gitlab-org/gitlab`). ## Number of imported projects | Name | Type | |-------------------------------------|---------| | `github_importer_imported_projects` | counter | This metric tracks the total number of projects imported over time. This metric does not expose any labels. ## Number of GitHub API calls | Name | Type | |---------------------------------|---------| | `github_importer_request_count` | counter | This metric tracks the total number of GitHub API calls performed over time, for all projects. This metric does not expose any labels. ## Rate limit errors | Name | Type | |-----------------------------------|---------| | `github_importer_rate_limit_hits` | counter | This metric tracks the number of times we hit the GitHub rate limit, for all projects. This metric does not expose any labels. ## Number of imported issues | Name | Type | |-----------------------------------|---------| | `github_importer_imported_issues` | counter | This metric tracks the number of imported issues across all projects. The name of the project is stored in the `project` label in the format `namespace/name` (e.g. `gitlab-org/gitlab`). ## Number of imported pull requests | Name | Type | |------------------------------------------|---------| | `github_importer_imported_pull_requests` | counter | This metric tracks the number of imported pull requests across all projects. The name of the project is stored in the `project` label in the format `namespace/name` (e.g. `gitlab-org/gitlab`). ## Number of imported comments | Name | Type | |----------------------------------|---------| | `github_importer_imported_notes` | counter | This metric tracks the number of imported comments across all projects. The name of the project is stored in the `project` label in the format `namespace/name` (e.g. `gitlab-org/gitlab`). ## Number of imported pull request review comments | Name | Type | |---------------------------------------|---------| | `github_importer_imported_diff_notes` | counter | This metric tracks the number of imported comments across all projects. The name of the project is stored in the `project` label in the format `namespace/name` (e.g. `gitlab-org/gitlab`). ## Number of imported repositories | Name | Type | |-----------------------------------------|---------| | `github_importer_imported_repositories` | counter | This metric tracks the number of imported repositories across all projects. This metric does not expose any labels. [14731]: https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/14731
