yamcs-cfs-error-log

A YAMCS plugin for the Core Flight System (CFS) Error Log format. It has the ability to parse error logs by removing the CFE_FS_Header_t and dumping the contents to a csv file.

To Build

NOTE:Makes an assumption that error log entries look like this structure:

typedef struct
{
    uint32                  LogEntryType;                                             
    uint32                  ResetType;                                                
    uint32                  ResetSubtype;                                             
    uint32                  BootSource;                                               
    uint32                  ProcessorResetCount;                                      
    uint32                  MaxProcessorResetCount;                                   
    CFE_ES_DebugVariables_t DebugVars;                                                
    CFE_TIME_SysTime_t      TimeCode;                                                 
    char                    Description[80];                                          
    uint32                  ContextSize;                                              
    uint32                  AppID;                                                    
    uint32                  Context[CFE_ES_ER_LOG_MAX_CONTEXT_SIZE / sizeof(uint32)]; 
} CFE_ES_ERLog_t;
mvn install -DskipTests

To package it:

mvn package -DskipTests
mvn dependency:copy-dependencies

The package command will output a jar file at yamcs-cfs-error-log/target. Note the dependency:copy-dependencies command; this will copy all of the jars to the yamcs-cfs-error-log/target/dependency directory. Very useful for integrating third-party dependencies.

To Integrate with YAMCS

This plugin functions as a YAMCS Telemetry Provider and will appear as a Datalink. To integrate this plugin, add the "com.windhoverlabs.yamcs.cfs.err_log.CfsErrLogPlugin" plugin to the "dataLinks" section of the YAMCS instance configuration. For example:

dataLinks:
  - name: err-logs
    class: com.windhoverlabs.yamcs.cfs.err_log.CfsErrLogPlugin
    stream: tm_realtime
    buckets: ["cfdpDown"]
    CFE_FS_ES_ERLOG_SUBTYPE: 1
    CFE_FS_ES_ER_ENTRY_SIZE: 264  # sizeof(CFE_ES_ERLog_t) 
    CFE_FS_ES_ERLOG_CONTEXT_ARRAY_SIZE: 32
    # CFE_FS_ES_ERLOG_SIZE = CFE_ES_ER_LOG_ENTRIES * sizeof(CFE_ES_ERLog_t) 
    CFE_FS_ES_ERLOG_SIZE: 5280  # Ignored when readUntilEOF is true
    readUntilEOF: false
    errLogFileConfig:
      mode: APPEND # APPEND, REPLACE, INACTIVE
      outputFile: cfe_es_err_log.csv
      errLogBucket: "cfdpDown"
