We as a whole know advantages of logging. It empower designers to rapidly investigate issues even prior to imitating it.

In dispersed frameworks, registering logs are put away in shared drive or at times on circulated workers itself. Later these logs are collected in devices like Splunk, LogDNA, Logstash to make them open at single spot and empower clients to look/read logs.

Since these instrument are not overseen by your association would it be a good idea for you to push touchy data likes individual subtleties of your clients, validation subtleties, installment data on these apparatuses? Evident answer is NO! So these subtleties are concealed in the majority of the application before application logs are produced. In short we are acceptable here😇.

Yet, presently I have one more inquiry. Shouldn’t something be said about the logs created by your application while sending messages to application clients? Do you have to make sure about those as well🤔?

Your messages may have reset secret phrase joins, verification OTP’s or installment receipts which may get traded off in the event that you don’t make sure about your email age logs.

Lets have take a gander at underneath model.

Here in my Rails application I am sending installment affirmation email to client when membership is restored by client. We should have take a gander at Mailer and html format document.

application/mailers/application_mailer.rb document looks like beneath:

class ApplicationMailer < ActionMailer::Base

notify_payment_success.html.erb record looks like beneath:

Presently lets produce email from rails support with beneath order:

ApplicationMailer.notify_payment_success(1).deliver

Woah we have another email now!

Stand by! Account_id is touchy data of client. What it’s doing in logs😳? Its likewise pushed to Splunk. Presently what🤨?

Try not to Frenzy. This can be fixed! What all do you require to browse if email was shipped off client? Do you need email body too? Well we dont need it in the vast majority of the cases. So how about we quit adding it in logs.

Of course ActiveSupport::LogSubscriber print whole email content in investigate mode. We have to overwrite this conduct. For the time being we should log just date, subject, sender and beneficiary.

Make a document log_subscriber.rb in config/initializers catalog and add underneath code in that.

module ActionMailer

class LogSubscriber

def deliver(event)

Presently restart your rails reassure and create another email. Lets take a gander at the logs.

Picture for post

We see just required subtleties in logs

I trust this will help you next time when you add another email in your Rails application.

Glad coding
