Resolution

Monitor data source errors can arise as a result of problems with the Citrix Monitor Service or the Monitor / Site database.

 

To troubleshoot Citrix Monitor Service issues:

  1. Verify if the Citrix Monitor Service is running within the Delivery Controller by examining Windows services.
  2. To ascertain whether the Delivery Controller is accessible over the network when the Director service is hosted externally, utilize the Windows PowerShell commands ping and nslookup. If these commands fail to execute successfully, it may suggest the presence of network-related problems.
  3. Restart the Citrix Monitor Service on the Delivery Controller.

 


If the errors persist, there may be issues with the Monitor database. To troubleshoot Monitor database issues:
  1. Check database connectivity and usability: Open PowerShell in the Delivery Controller and execute the following script. If the script reports any error check if the connection strings are correctly configured.
    $monitorDBConnectionString = Get-MonitorDBConnection -DataStore Monitor
    $siteDBConnectionString = Get-MonitorDBConnection -DataStore Site
    
    # Verify that the connection strings are non-empty
    Write-Host $monitorDBConnectionString
    Write-Host $siteDBConnectionString
    
    Test-MonitorDBConnection -DataStore Monitor -DBConnection $monitorDBConnectionString
    Test-MonitorDBConnection -DataStore Site -DBConnection $siteDBConnectionString
    
  2. Check for whitespaces in connection string:
    • Examine MonitorInfrastructure module logs using CDF Control for errors related to Monitor database connection string (Refer to Citrix KB article CTX130320 to use CDF Control).
    • Ensure that the Monitor and Site database connection strings adhere to the correct format (See Database address formats).
  3. Check SQL Server disk space:
    • Verify that the machine hosting the SQL Server has adequate disk space.

If the error persists, review Director and Monitor service event logs (Refer to Citrix KB article CTX130320 to use CDF Control).

Problem Cause

The following issues can cause the problem:

  • Citrix Monitor Service is in an unhealthy state.
  • Citrix Monitor Service cannot connect to the database.
  • Director cannot connect to the Citrix Monitor Service.
