Email Alerts are not received...

In one of application, Email alerts are sent using SQL sp_send_dbmail stored procedure. Email alerts were working properly, but suddenly noticed email alerts are not received.

To troubleshoot the issue, first I checked the msdb.dbo.sysmail_event_log table using the below query.

SELECT log_id, event_type, log_date, description, process_id, mailitem_id, account_id, last_mod_date, last_mod_user
log_date DESC

If there is any error, you should see records with the event_type value as error.
In my case there are records with event_type value as error, and the description value for those records is same as below

The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 3 (2018-02-01T10:41:27). Exception Message: Cannot send mails to mail server.

Tips to avoid empty pages and white spaces in SSRS reports...

Sometimes we find that there are white spaces or empty pages in the SSRS report viewer output or the PDF output. In this post I am going to mention the tips we can use to avoid those.
  • Set the ConsumeContainerWhitespace property of the report to True.
  • Set the body content to fit enough for the Report Page Width. Consider the margins too. Body width + Left and Right margins needs to be less than the report page width. Otherwise there will be blank spaces while exporting to PDF.
  • Remove unwanted space between the tables or charts in the report.
  • Check the page breaks, and disable those if there are no data by checking the Count of the data set.
  • Set the page breaks if you are setting the visibility of a particular section by using a parameter, by applying the same condition for the Disable property.
If those things were done properly, there will not be any unwanted white spaces or empty pages in the report.
