# System health module

The system health module allows you to check the running state of the ThinLinc master, agent and Web Access services. There is also a tool to perform a user or group lookup which reports the time for the lookup.

- Service status reports the current running state of the

    master (`vsmserver.service`), agent (`vsmagent.service`), and Web Access (`tlwebaccess.service`) services.

- Users and group lookup allows you to test the performance of user and group lookup on the system.

  Fill in values for username and/or group and click the Test user and group lookup button to perform a lookup.
