• What is the cause and solution for SAP error message S1304 - No network collector running on any & application server ?

  The SAP error message S1304 indicates that there is no network collector running on any application server. This error typically arises in the context of SAP's monitoring and performance analysis tools, particularly when using the SAP Solution Manager or similar systems that rely on network collectors to gather performance data.
  Cause:
  
  Network Collector Not Started: The most common cause is that the network collector service is not running on any of the application servers.
  Configuration Issues: There may be misconfigurations in the network collector settings or in the SAP system configuration.
  Authorization Issues: The user or service account running the network collector may not have the necessary permissions.
  Network Issues: There could be network connectivity issues preventing the collector from communicating with the application servers.
  System Load: High system load or resource constraints may prevent the network collector from starting.
  
  Solution:
  
  
  Start the Network Collector:
  
  Check if the network collector is running. You can do this by using transaction SM51 to view the list of application servers and their running processes.
  If it is not running, you can start it using transaction RZ10 or through the appropriate configuration settings in the SAP system.
  
  
  
  Check Configuration:
  
  Verify the configuration settings for the network collector in the SAP system. Ensure that the parameters are correctly set in the instance profile.
  Check the settings in transaction RZ11 for parameters related to the network collector.
  
  
  
  Review Authorizations:
  
  Ensure that the user or service account has the necessary authorizations to run the network collector. You may need to check roles and profiles assigned to the user.
  
  
  
  Check Network Connectivity:
  
  Ensure that there are no network issues preventing communication between the network collector and the application servers. You can use tools like ping or traceroute to diagnose connectivity issues.
  
  
  
  Monitor System Resources:
  
  Check the system resources (CPU, memory, etc.) to ensure that the application server is not overloaded. If the server is under heavy load, consider optimizing performance or scaling resources.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) and the network collector logs for any error messages or warnings that could provide more context about the issue.
