Error log capture in Salesforce

The purpose of the error log framework is to keep track of records or system failures so that the system administrator can resolve to enhance the data loss and enhance the system process.

For any apex failure, the error logs were maintained through this custom solution. To build an error log framework, it is necessary to know the basics of exception handling in Apex.

1. Create a custom object
2. Create the Apex class
3. Sample Trigger

Create a Custom Object

Object Name: Error

API Name: Error__c

Fields:

Field Label	Field Name	Data Type
Class Name	Class_Name__c	Text(100)
Description	Description__c	Long Text Area(32768)
Error Name	Name	Auto Number
Method Name	Method_Name__c	Text(100)
Object Name	Object_Name__c	Text(18)
Stack Trace	Stack_Trace__c	Text(255)
Type	Type__c	Text(100)
User Id	User_Id__c	Text(20)

Create the Apex Class

public class CustomHandleException extends Exception 
{
    public static void LogExceptionMethod(Exception e,string objname)
    {
        try
        {
            Error__c err = new Error__c();
            err.Description__c = e.getMessage();
            err.Stack_Trace__c = e.getStackTraceString();
            err.Type__c = e.getTypeName();
            err.Class_Name__c = 'CustomHandleException';
            err.Method_Name__c = 'LogExceptionMethod';
            err.User_Id__c = UserInfo.getUserId();
            err.Object_Name__c = objname;            
            insert err;          
            
        } finally{
            
        }            
    }
}

Sample Trigger

This trigger has been intentionally written to through error so as to log the error

trigger ErrorAccountTrigger on Account (After insert) {
    
    string objName;    
    list <contact> CntLst = new list <Contact> ();
    List<Account> accnew = Trigger.New;
    
    try{
        List<Account> accnew = Trigger.New;
        for(Account accItems: accnew){
            
            Contact newContact = new Contact();            
            newContact.AccountId = accItems.Id;            
            cntLst.add( newcontact);
            
        }    
        if(!cntlst.isEmpty())  { 
            insert cntLst;
            
        } 
        
    } catch (Exception e) {
        for(sobject obj:accnew){
            objName = string.valueof(obj.getsobjecttype());
            system.debug('objName' + objName);
        }
        CustomHandleException.LogExceptionMethod(e, objName);
    }
}
