    About this task

    If the monitoring app is down, the Zscaler tunnel status is either 51(SERVICE-DOWN-ERROR) or 56(SYSTEM_SOCKETS_EXHAUSTED_ERROR). When that happens, a remediation check runs, which shuts down and then starts the Zscaler app.

    By default, the Zscaler monitoring check (zscaler-monitoring-check) runs automatically every 30 minutes. If you are experiencing problems with your Zscaler app, you may want to run the check more often or immediately. For details, see Customize the Zscaler monitoring check.

    Procedure

    1. Navigate to All > Remediate Zscaler VPN > Monitoring Status.

      • If the Zscaler app is running properly, the Application Status column displays the Up value.

    2. If the Application Status column displays the Down value, the remediation check (zscaler-remediation-check) runs.
