Motivation Log is an indispensable function for the development of a software system. Whether it is problem tracing or status analysis, with log assistance, developers can trace the problem. For the implementation modules of these log functions, developers can choose the EventLog built in. net, or the third-party log4net .... And so on. There are so many implementation modules that can be used to simplify the workload of developers, but it also brings

exceptions to system logs. That is to say, we can view the exceptions in the event viewer. For convenience, create an appexception. CS file in the app_code folder of the website and perform the following steps: 1. Add "using system. diagnostics;" reference. The diagnostics namespace provides classes that can interact with system processes, event logs, and performance counters. 2. Create a method named predictionlog () to write a log in the event log of the application. 3. In the exceptionlog ()

Typically, people use file-based logs. There is no problem with this, but it is easier to use Windows to provide system internal logs. If you have administrative privileges, you can create a new log at any time: Copy Code code as follows: New-eventlog-logname Mylog-source Jobdue, Jobdone, remark This command creates a log called MyLog, which originates from "Jobdue", "Jobdone" and "remark". Admin permissions are just to create the lo

Spark. reducer. maxmbinflight 48 Each reduce task obtains the maximum size (in MB) of map output at the same time ). Since each map output requires a buffer to receive it, this means that each reduce task has a fixed memory overhead, so you need to set a small point unless there is a lar
