It helps us to understand what is going wrong in our systems by analyzing logs from different sources like Github or Heroku etc., it really help me as we use roll bar for monitoring of applications which are deployed using AWS environments such that I can know if there any issues before they impact production traffic so this feature helped my team alot! nothing about them just continue doing their good job!! but i would suggest adding more metrics into report view because sometimes some data might be missing due delay between writing log message & reporting time while viewing reports you have no idea how many times your application crashed during last day?
