This page contains some hints for troubleshooting when for example some dashboards or views are empty.

As starting point you should classify the problem: 

• Is it a general problem in the application that seems to affect all or several different parts of the application?
• Or is it rather missing data on some particular views?

• Try reloading the complete page (F5 for many browsers)
• Try loading the same application in a different browser / on a different PC
• Check if the problem is specific to a particular managed system
• Check the Console in the developer tools (F12): Do you see any exception indicating a problem?

Most pre-defined dashboards per system type are populated with metrics from the Monitoring and Alerting infrastructure that is also providing the content for System Monitoring. As a result, if any metrics do not report data, the first check is to verify if system monitoring is working correctly and if metrics in System Monitoring report data. If System Monitoring is not working correctly, please open a support ticket with component SV-FRN-APP-SYM.

Common checks

1. If System Analysis dashboards show no metric data for a particular system: Navigate to System Monitoring for the same system. You can use the link in the toolbar (top right) to directly select the current system in System Monitoring. 
   1. If System Monitoring does not report metric data for a particular system either, then open a support ticket for System Monitoring (SV-FRN-APP-SYM).
   2. If System Monitoring reports data properly and metric data is only missing in System Analysis in a freshly configured FRUN system: potentially System Analysis was launched before setting up System Monitoring. Up to FRUN 2.0 FP02, this generates a wrong default configuration. Double check table WEA_UI_CONFIG: if there is an entry "raw.days" it should have the value 28. If the value is 0 then correct it to 28 and relaunch System Analysis.
2. No data for historical time ranges (age > 28 days): by default System Monitoring data is retained for 28 days. You can configure System Analysis Aggregation to retain selected metrics for selected systems for a longer period. 
    

Starting with FRUN 3.0 Self Monitoring alerts are available for RCA Capabilities to inform you when for a capability data is expected but not available.

With report RCA_DEACTIVATE_CAPABILITIES you can do some mass changes without disabling/enabling the capability for each system separately.

You can enter in the selection fields several capabilities (wildcard * is possible) and/or limit the execution to LMDBIDs.

These options are available

• Display only current status
  Just list all systems for the selected capabilities
  
• Inactive -> active
  Activate all inactive the selected capabilities
  
• Active -> inactive
  De-Activate the selected capabilities
  
• Active -> active (Reconfigure)
  Re-activate all active the selected capabilities
  
  

In case you have multiple systems and capabilities to be changed the report should be executed in background. To avoid that too many parallel requests are executed the time between two executions can be configured (default 1s).

In general you can check table RCA_INBOUND_LOG in FRUN via SE16, MESSAGE_TYPE="E" will filter on errors and and the date ( field UTC_DATE) . Here you can see errors of data that are sent to FRUN. When changing the user parameters in SE16 (Menu: Settings-> User Parameters -> ALV Grid Display) you can see the detailed error messages and can download the table.
However there might be already problems in collecting data either in the agent application, in the managed system or on the way.

HANA Metrics

HANA Metrics are collected via an operation of the SAP Hostagent. Check in Agent Administration for the HANA system if the collectors are running:

1. Open Agent Internals
2. Select tab Collector Framework
3. expand the capability HANA_*
   Check for exceptions or if the coverage is below 1.
4. Select the tab Logs
   Choose the thread rca worker <collector_key>

ABAP_WP_OVERVIEW

ABAP work process samples (/SDF/SMON) are collected via a RFC from the SDA usually with user SDAGENT. Check in Agent Administration for the ABAP system if the collector is running:

1. Open Agent Internals
2. Select tab Collector Framework
3. expand the capability ABAP_WP_OVERVIEW
   Check for exceptions or if the coverage is below 1.
4. Select the tab Logs
   Choose the thread rca Worker <FRUN_SID>.ABAP_WP_OVERVIEW_<Managed_SID>

General

If the collector is missing in the collector framework there are several reasons:

1. Properties are missing
   If the rca properties are missing executing SSI for the system or Configure Agent can re-deploy the properties
2. Configuration files are missing
   If the json config files are missing a reconfiguration of the capability will re-deploy the files. You can use report RCA_DEACTIVATE_CAPABILITIES to Reconfigure all active capabilities.

Any HANA statement details view in System Analysis shows the statement text “Statement not available” or nothing.

• Check the log of background job SAP_FRN_RCA_HANA_STATEMENT_SYNC in transaction SM37:
  • The log shows any general issue accessing the agent, try to fix them first.
  • The log also includes how many new statement hashes were found and how many statements were persisted
    Example: “There were 293  new HANA statement hashes since ___ (UTC).” -> “There were 0  new unique HANA statement hashes written to the database.”
    If the number of persisted new unique statements is significantly lower or zero, there might be a problem with the agent. The SHA needs to be at least PL51.
• After that you might want to reset the synchronization table. For this you can execute program RCA_HANA_STATEMENT_DEL in transaction SE38 with the selection:
  • HANA Statement hash = *
  • Mark the check box "Delete only empty entries".

Ad-Hoc SQL views trigger SQL statements as ad hoc calls directly towards the SAP Host Agent on the managed HANA system. The statements are delivered as part of the SAP Host Agent.

For any errors executing Ad-Hoc SQL statements:

• Check the application log on FRUN via transaction SLG1. Use object SYS_ANA and subobject ADHOCSQL.
• You will see two different types of calls:
• GetCapabilities determines if the SAP Host Agent supports the "ExecuteDatabaseOperation" method or if the older approach "ExecuteOperation" must be used.
• ExecuteDatabaseOperation lists the actual SQL statement name that is executed and the number of result rows or the error message executing that statement.

The page ABAP Performance does not display any data which could have multiple reasons:

• Check in the managed system in ST03 if aggregated data is available. If this is not the case follow SAP note 2369736 - Troubleshooting missing data in ST03N/ST03.
• In case only data of some views are missing like User Profile check in the managed system in ST03 if this area is probably not enabled for the collector:
  Collector and Performance DB -> Workload collector -> Instance Collector -> Control
   

• Check if SSI has been executed successfully (step 2 for activity Configure Statistical Records Aggregation)
• Use the link "ABAP Performance KPI Setup" in System Analysis to open the "Statistics Records Aggregates Administration" (/sap/bc/webdynpro/sap/wd_statragg_cockpit). From here you can check:
  
  • Which instance collects the data
  • Status of collection
  • Jump to Agent Administration for logs and Agent Internals → Collector Framework. There should be a collector "statragg" for the system.
  • Find out which agent is relevant for collection. 
    Filter for the system. You can see from which instance the data is collected.
    If you have multiple instances you might need to add the column HOST_NAME.With this physical host name you can search then in Agent administration for further issues.
• Agent Administration
  Open Agent internals and click on tab Logs.
  STATRAGG data are usually collected around the full hour. Enter in the the last full hour (usually in UTC) and then you should be able to select in the Threads List box the statragg collector:
