Product Details

Audit Trail Component + Full Source Code

Version v1.0

 

Introduction

Audit trail component stores database actions (Add, Update, Delete), business actions (you can specify them), sends notifications and logs its own errors, also it’s dynamic as it gives user the ability to specify [Business actions], [Emails that notifications will be sent to], [Notification’s subject] and [Notification’s Message], also you can search for all the data has been stored by the component by predefined methods.

Framework: .net standard 2.1

Packages :

  • Microsoft.EntityFrameworkCore.SqlServer 3.1.3
  • Newtonsoft.Json  12.0.3

Hangfire Packages :

  • Hangfire.AspNetCore
  • Hangfire.SqlServer

Features :

  • Store database actions and business actions.
  • Send notifications.
  • Log send notification process, and retry if it’s failed.
  • Log errors.
  • Dynamic: User can specify actions and emails and specify if the component should send notification when a specific action happened.

Recommendation :

use background job to execute component methods, to ensure that the original request time will not be increased.

 

Database Tables

Audit.Action 

to store actions lookup data

Audit.ActionUserGroup

to make relation between [action], and emails, so if this action happened then the component will   send notification to the related emails with the specified message.

Audit.AuditTrail

to store the audit data

Audit.ErrorLog

to log the component errors

Audit.Notification

to store the notifications that the component will send to emails

Audit.NotificationLog

to log the send notification process, component will store every (send email) retry and store if it’s done successfully or not with error message

 

How to Register

 

  • In your project, you need to install Hangfire nugetpackages [Hangfire.AspNetCore, Hangfire.SqlServer] ,or any package to perform background processing.
  • Also you need to implement[ IEmailService ] interface to send notification emails .

 

Startup class

  • In method [ConfigureServices]

        #region hangfire

            // Add Hangfire services.

            services.AddHangfire(configuration => configuration

                .SetDataCompatibilityLevel(CompatibilityLevel.Version_170)

                .UseSimpleAssemblyNameTypeSerializer()

                .UseRecommendedSerializerSettings()

                .UseSqlServerStorage(Configuration.GetConnectionString(“DefaultConnection”), new SqlServerStorageOptions

                {

                    CommandBatchMaxTimeout = TimeSpan.FromMinutes(5),

                    SlidingInvisibilityTimeout = TimeSpan.FromMinutes(5),

                    QueuePollInterval = TimeSpan.Zero,

                    UseRecommendedIsolationLevel = true,

                    UsePageLocksOnDequeue = true,

                    DisableGlobalLocks = true

                }));

 

            // Add the processing server as IHostedService

            services.AddHangfireServer();

 

            #endregion

 

            #region Audit

            services.AddScoped<IEmailService, EmailService>();

 

            //AddAuditTrail classes

            services.AddAuditTrail(Configuration.GetConnectionString(“DefaultConnection”),

                 new List<AuditActionDto> {

                    new AuditActionDto() { ActionCode =”CreateOrder”,SendNotification=true,NotificationFromEmail=”admin@gmail.com

                                        ,NotificationEmails=”ahmed@yahoo.com,ali@hotmail.com”,NotificationSubject=”subject “

                                        ,NotificationMessage=”sample message”},

                    new AuditActionDto() { ActionCode = “DeleteOrder”,SendNotification=true,NotificationFromEmail=”admin@gmail.com”,

  NotificationEmails=”ahmed2@yahoo.com,ali2@hotmail.com”,NotificationSubject=”subject “  ,

   NotificationMessage=”sample message2” },

                    new AuditActionDto() { ActionCode = “UpdateOrder” ,SendNotification=true},

                   new AuditActionDto() { ActionCode = “NewUpdateOrder” ,SendNotification=false}});

 

 

            //register background job to Check Notifications to send emails

            var sp = services.BuildServiceProvider().CreateScope().ServiceProvider;

            var notificationService = sp.GetService<INotificationPublicService>();

                 JobStorage.Current = new SqlServerStorage(Configuration.GetConnectionString(“DefaultConnection”),

                 new SqlServerStorageOptions

            {

                CommandBatchMaxTimeout = TimeSpan.FromMinutes(5),

                SlidingInvisibilityTimeout = TimeSpan.FromMinutes(5),

                QueuePollInterval = TimeSpan.Zero,

                UseRecommendedIsolationLevel = true,

                UsePageLocksOnDequeue = true,

                DisableGlobalLocks = true

            });

            RecurringJob.AddOrUpdate(() => notificationService.CheckNotificationsAndSend(), Cron.Daily);

            #endregion

 

How to create tables

  • Open [Package manager console] and in the [Default project] list .. select [AuditTrailComponent] project
  • Write the below commands
    • add-migration InitiatAudit -context AuditDbContext
    • update-database -context AuditDbContext

 

How to use

 

  • Inject this interface to your class [IAuditTrailService]
  • To store business action

BackgroundJob.Enqueue(() => AuditTrailService.SaveCustomActionsAuditTrailAsync(“DeleteOrder”, “sample data by hangfire”, “username1”));

 

  • To store database action ,use the below code before Entity framework save changes method

BackgroundJob.Enqueue(() =>AuditTrailService.SaveDbActionsAuditTrailAsync(ApplicationDbContext.ChangeTracker.Entries()

            .Select(a =>

            new DatabaseChangesDto

            {

                Entity = a.Entity,

                OriginalValues = a.OriginalValues.ToObject(),

                CurrentValues = a.CurrentValues.ToObject()

            }).ToList()));

 

  • To search for audit data

//Inject this interface [IAuditTrailService]

AuditTrailFilterDto model = new AuditTrailFilterDto {Audit_ActionCode=”DeleteOrder” };

var result=await AuditTrailService.Search(model);

 

  • To search for Notifications

//Inject this interface [INotificationPublicService]

NotificationFilterDto model = new NotificationFilterDto { Audit_ActionCode=”DeleteOrder” };

var result=await NotificationPublicService.SearchNotifications(model);

 

  • to search for notification log

//Inject this interface [IErrorLogPublicService]

NotificationLogFilterDto model = new NotificationLogFilterDto { };

 var result = await NotificationService.SearchNotificationLogs(model);

 

  • to search for error logs

//Inject this interface [IErrorLogPublicService]

ErrorLogFilterDto model4 = new ErrorLogFilterDto();

var result = await ErrorLogPublicService.Search(model4);
