+# View Grafana server stats
+
+If you are a Grafana server admin, then you can view useful statistics about your Grafana server in the Stats tab.
+
+> **Note:** Only Grafana server admins can access the **Server Admin** menu. For more information about about admin permissions, refer to [Grafana server admin]({{< relref "../permissions/_index.md" >}}).
+
+## View server stats
+
+1. Log in to your Grafana server with an account that has the Grafana Admin flag set.
+1. Hover your cursor over the **Server Admin** (shield) icon in the side menu and then click the **Stats** tab.
+
+## Available stats
+
+The following statistics are displayed in the Stats tab:
+
+- Total users
+  **Note:** Total users = Total admins + Total editors + Total viewers
+- Total admins
+- Total editors
+- Total viewers
+- Active users (seen last 30 days)
+  **Note:** Active users = Active admins + Active editors + Active viewers
+- Active admins (seen last 30 days)

+- Active sessions
+- Total dashboards
+- Total orgs
+- Total playlists
+- Total snapshots
+- Total dashboard tags

+
+## Counting users
+
+If a user belongs to several organizations, then that user is counted once as a user in the highest organization role they are assigned, regardless of how many organizations the user belongs to.
+
+For example, if Sofia is a Viewer in two organizations, an Editor in two organizations, and Admin in three organizations, then she would be reflected in the stats as:
+
+- Total users     1
+- Total admins    1
