Last modified by Vincent Massol on 2026/09/11 09:40
Reference
Every ping your instance sends carries the data below, and nothing else. No page content, no wiki name and no user name ever leaves the instance.
| Data | Field | What is sent | Notes |
|---|---|---|---|
| Instance id | distribution.instanceId | A UUID generated once for the instance | The IP address is not kept, so there is no way to find out who owns a given id |
| Distribution | distribution.extension | The id, version and features of the package the instance runs | org.xwiki.platform:xwiki-platform-distribution-war for the WAR, org.xwiki.platform:xwiki-platform-distribution-jetty-hsqldb for the standalone Jetty and HSQLDB package |
| Installed extensions | extensions | The id, version and features of every installed extension | |
| Operating system | os | Name, architecture and version | |
| Database | database | Name and version | |
| Java | java | Vendor, version and specification version | |
| Servlet container | servletContainer | Name and version | |
| Memory | memory | Maximum, allocated, used and free JVM memory | In bytes |
| Documents | documents | The number of documents in the main wiki, in each subwiki and in total | Pages that come from extensions are counted; the per-subwiki counts are an array with no wiki names in it |
| Users | users | The number of users in the main wiki, in each subwiki and in total | Only active users are counted; the per-subwiki counts are an array with no wiki names in it |
| Wikis | wikis.total | The number of wikis, the main wiki included | |
| Dates | date | When the ping was sent, when the instance first pinged, and how long it has been pinging | current and first are ISO-8601 instants, since is a number of days |
