Status pages

License Server (FLS) administrator can make requests to the server in order to get brief information about health, current configuration, and connection state. In case you have a problem, or require full information, visit the FLS dashboard.

Health check

The /health page shows if the server is registered and if it has connection to JetBrains Account. In the first case it returns 200 OK and presents the serverUID and lastCallHome. Otherwise, the response is 500 Internal Error with a problem description.

lastCallHome shows the time of last connection to JetBrains servers. If the server is not able to connect to account.jetbrains.com within a certain time limit, FLS stops serving user tickets and tries to connect to JetBrains Account every minute, see Communication with JetBrains Account.
