Helps with DAX for Power pivot

[thangvan114]

I'm analysing dataset for IT request from Oct-20 to date, sample data as below. I want to analyse the data, and provide dashboard for each month reporting period (end of month): Total request submit in the month (02/21: 4, 03/21: 3), Total request close in the month (02/21: 2, 03/21:3), Overdue request by end of each month (02/21: 2, 03/21:3). Can you please help with the measure formula? Thank you.
