Reviewing the audit log for your organization

The audit log allows organization admins to quickly review the actions performed by members of your organization. It includes details such as who performed the action, what the action was, and when it was performed.

Accessing the audit log

The audit log lists events triggered by activities that affect your organization within the current month and previous six months. Only owners can access an organization's audit log.

既定では、過去 3 か月のイベントのみが表示されます。 古いイベントを表示するには、created パラメーターを使って日付範囲を指定します。 詳細については、「Understanding the search syntax」 (検索構文の理解) を参照してください。

  1. GitHub Enterprise Server の右上隅にあるプロファイル写真をクリックし、 [自分の Organization] をクリックします。 プロファイル メニューの組織

  2. 組織の隣の [設定] をクリックします。 [設定] ボタン

  3. In the Settings sidebar, click Audit log. Org audit log settings in sidebar

Searching the audit log

各監査ログ エントリの名前は、action オブジェクトまたはカテゴリ修飾子と、その後の操作の種類で構成されます。 たとえば、repo.create エントリは repo カテゴリに対する create 操作を意味します。

各 Audit log エントリには、次のようなイベントに関する適切な情報が表示されます:

  • アクションが実行された エンタープライズまたはOrganization
  • アクションを実行したユーザー (アクター)
  • アクションによって影響を受けたユーザー
  • アクションの対象となったリポジトリ
  • 実行されたアクションです
  • アクションが実行された国
  • アクションが発生した日時

テキストを使用してエントリを検索することはできません。 ただし、さまざまなフィルターを使用すれば検索クエリを作成できます。 ログを検索するときに使用される多くの演算子 (->< など) は、GitHub Enterprise Server 全体で検索するものと同じ形式です。 詳細については、「GitHub 上での検索」を参照してください。

操作に基づく検索

operation 修飾子は、アクションを特定の操作の種類に限定するときに使ってください。 たとえば次のような点です。

  • operation:access は、リソースがアクセスされたすべてのイベントを検索します。
  • operation:authentication は、認証イベントが実行されたすべてのイベントを検索します。
  • operation:create は、リソースが作成されたすべてのイベントを検索します。
  • operation:modify は、既存のリソースが変更されたすべてのイベントを検索します。
  • operation:remove は、既存のリソースが削除されたすべてのイベントを検索します。
  • operation:restore は、既存のリソースが復元されたすべてのイベントを検索します。
  • operation:transfer は、既存のリソースが移動されたすべてのイベントを検索します。

リポジトリに基づく検索

repo 修飾子は、アクションを特定のリポジトリに限定するときに使ってください。 たとえば次のような点です。

  • repo:my-org/our-repo は、my-org 組織内の our-repo リポジトリで発生したすべてのイベントを検索します。
  • repo:my-org/our-repo repo:my-org/another-repo は、my-org組織内の our-repo および another-repo リポジトリで発生したすべてのイベントを検索します。
  • -repo:my-org/not-this-repo は、my-org 組織内の not-this-repo リポジトリで発生したすべてのイベントを除外します。

repo 修飾子内にアカウント名を含める必要があります。repo:our-repo を検索するだけでは機能しません。

ユーザーに基づく検索

actor 修飾子は、アクションを実行した人に基づいてイベントの範囲を指定できます。 たとえば次のような点です。

  • actor:octocatoctocat によって実行されたすべてのイベントを検索します。
  • actor:octocat actor:hubotoctocat および hubot によって実行されたすべてのイベントを検索します。
  • -actor:hubothubot によって実行されたすべてのイベントを除外します。

使用できるのは GitHub Enterprise Server のユーザー名のみであり、個人の実名ではないことに注意してください。

Search based on the action performed

To search for specific events, use the action qualifier in your query. Actions listed in the audit log are grouped within the following categories:

Category nameDescription
dependabot_alertsContains organization-level configuration activities for Dependabot alerts in existing repositories. For more information, see "About Dependabot alerts."
dependabot_alerts_new_reposContains organization-level configuration activities for Dependabot alerts in new repositories created in the organization.
dependabot_security_updatesContains organization-level configuration activities for Dependabot security updates in existing repositories. For more information, see "Configuring Dependabot security updates."
dependabot_security_updates_new_reposContains organization-level configuration activities for Dependabot security updates for new repositories created in the organization.
discussion_postContains all activities related to discussions posted to a team page.
discussion_post_replyContains all activities related to replies to discussions posted to a team page.

teamContains all activities related to teams in your organization.
team_discussionsContains activities related to managing team discussions for an organization.
workflowsContains activities related to GitHub Actions workflows.

You can search for specific sets of actions using these terms. For example:

  • action:team finds all events grouped within the team category.
  • -action:hook excludes all events in the webhook category.

Each category has a set of associated actions that you can filter on. For example:

  • action:team.create finds all events where a team was created.
  • -action:hook.events_changed excludes all events where the events on a webhook have been altered.

Search based on time of action

Use the created qualifier to filter events in the audit log based on when they occurred. 日付の書式設定は、ISO8601 標準の YYYY-MM-DD (年-月-日) に従う必要があります。 日付の後にオプションの時刻情報 THH:MM:SS+00:00 を追加して、時間、分、秒で検索することもできます。 これは、T の後に HH:MM:SS (時-分-秒)、UTC オフセット (+00:00) が続きます。

日付に対して検索を行う場合、結果をさらにフィルタリングするためにより大きい、より小さい、範囲の修飾子を利用できます。 詳細については、「Understanding the search syntax」 (検索構文の理解) を参照してください。

For example:

  • created:2014-07-08 finds all events that occurred on July 8th, 2014.
  • created:>=2014-07-08 finds all events that occurred on or after July 8th, 2014.
  • created:<=2014-07-08 finds all events that occurred on or before July 8th, 2014.
  • created:2014-07-01..2014-07-31 finds all events that occurred in the month of July 2014.

Note: The audit log contains data for the current month and every day of the previous six months.

Search based on location

Using the qualifier country, you can filter events in the audit log based on the originating country. You can use a country's two-letter short code or its full name. Keep in mind that countries with spaces in their name will need to be wrapped in quotation marks. For example:

  • country:de finds all events that occurred in Germany.
  • country:Mexico finds all events that occurred in Mexico.
  • country:"United States" all finds events that occurred in the United States.

Using the audit log API

You can interact with the audit log using the GraphQL API.

To ensure your intellectual property is secure, and you maintain compliance for your organization, you can use the audit log GraphQL API to keep copies of your audit log data and monitor:

  • 組織またはリポジトリの設定へのアクセス
  • アクセス許可の変更
  • 組織、リポジトリ、またはチームの追加または削除されたユーザー
  • 管理者に昇格されるユーザー
  • GitHub Appの権限の変更

The GraphQL response can include data for up to 90 to 120 days.

For example, you can make a GraphQL request to see all the new organization members added to your organization. For more information, see the "GraphQL API Audit Log."
