19 19  There is a need to see runtime level logging in cases where it is unclear whether that specific runtime has started up or not. In eMagiz, you won't receive logging if the start-up fails because no established connection can send logging to eMagiz. When this particular runtime runs on-premises, you can see that specific logging on the runtime in the wrapper.log. In this microlearning, we will learn how to find the wrapper log and search within the wrapper log to find the corresponding error and subsequently analyze that error.

54 54  Before we can interpret the wrapper.log, the first action will be to find the wrapper.log. The wrapper.log is available within the data folder of each eMagiz runtime that is running on-premises. To see it, you first need to know the location where you saved and unpacked the runtime zips. Suppose you open the runtime you want to interpret the wrapper log and open the data folder. Within the data folder, there is a folder called log. You will see a file called wrapper which can be opened with a tool such as Notepad++.

62 62  One way to do so would be to stop the runtime and delete the data folder without deleting the h2 folder. That would initiate a clean restart of the runtime to alleviate the problems. In case of structural issues, you should dive into the logging and analyze the issues in more detail.
