  Hi,

  I have implemented Serilog.Sinks.AwsCloudWatch to log my data to AWS-CloudWatch But the problem is according to the documentations of SeriLog I can log data as per LogEventLevel to the CloudWatch which creates huge amout of unnecessary data

  What if I want to log only the data which get logged into AuditLog and AuditLogAction table from database to AWS-CloudWatch.

  Is this possible and how to implement it ?

  Yes you can.

  You can custom AuditingStore to save auditlog to AWS-CloudWatch.

  Hi,

  As you said I tried implementing AudtingStore. But I was not able to log the data like AbpAuditLog.I think I missed out something I got reference from the source code Below is my code , Please help if something is wrong in the implementation

  [Dependency(TryRegister = true)]
  public class AWSAuditingStore: IAuditingStore, ISingletonDependency
      {
          public ILogger<AWSAuditingStore> Logger { get; set; }
  
          public AWSAuditingStore()
          {
              Logger = NullLogger<AWSAuditingStore>.Instance;
          }
  
          public Task SaveAsync(AuditLogInfo auditInfo)
          {
              Logger.LogInformation("AWSAuditingStore : {0}", auditInfo.ToString());
              return Task.FromResult(0);
          }
      }

  Hi,

  I create a simple implementation, but I don't know about AWS-CloudWatch, I hope I can help you.

  [Dependency(ReplaceServices = true)]
  [ExposeServices(typeof(IAuditingStore))]
  public class CustomAuditingStore : AuditingStore
  {
      private readonly LogEventBatch _repo = new LogEventBatch();
      private readonly IAmazonCloudWatchLogs _client;
      private int _requestCount = 5;
  
      private static readonly Regex InvalidSequenceTokenRegex = new
          Regex(@"The given sequenceToken is invalid. The next expected sequenceToken is: (\d+)");
  
      public CustomAuditingStore(
          IAuditLogRepository auditLogRepository,
          IGuidGenerator guidGenerator,

      public override async Task SaveAsync(AuditLogInfo auditInfo)
      {
          AddSingleMessage(JsonConvert.SerializeObject(auditInfo));

          await base.SaveAsync(auditInfo);
      }
  
      private void AddSingleMessage(string message)
      {
