We repeat the process several times and write down the "Last Run Result" values. Then, after observing return codes "0x1" and "0x2," we switch to the "History" tab and select an event "Action Completed" Event ID: , as shown in Figure However, even though the Python execution throws exceptions, the Task Scheduler considers action completed successfully.
Thus, it is not convenient for us to detect exceptions in Python execution by viewing task execution history. Switch to the "Details" tab. We can see more detailed information about the event log, as shown in Figure We can find another "Action Completed" log in the "History" tab, in which the return code is In the preceding section, we created a trigger that starts a task at PM every day. We call this trigger the time-based trigger. Another trigger type is the event-based trigger, which starts an action after a specific event Dinita, Next, we create the third task, "failed to save data," that starts to run when the task detects return code We follow the steps in Section 2.
Rather than using "python. The action will fail since the fake program name is not an actual program. We use errors from these two tasks to imply exceptions in Python script execution. Select the "failed to access web page" task and click on the "Properties" button in the "Actions" pane to open the "Properties" dialog. In the dialog, switch to the "Trigger" pane, as shown in Figure Click on the "Edit…" button to open the "Edit Trigger" dialog.
Next, we select "On an event" in the "Begin the task" dropdown list and select "Custom" in the "Settings" section. Switch to the "XML" tab and select the "Edit query manually" checkbox. When a dialog with a warning message appears, we click the "Yes" button to continue. Then, the text box becomes editable. We enter the following query in the text box.
The "New Event Filter" dialog should look like Figure We click on a series of "OK" buttons one after the other to close dialogs and save changes. Now we want the return code to start the task "failed to save data. We use the following query to define the custom event filter:. When the task is complete, we write down the value that is in the "Last Run Result" column. We repeat the process several times until our record has 0x1 and 0x2 values. Selecting the task "failed to access web page," we notice some errors, as shown in Figure The Python script execution exception does not directly generate the errors, but the errors tell us that the Python script failed to access the web page.
We also see some errors when selecting the task "failed to save data," shown in Figure The errors inform us that the Python script failed to save data into the database table. These two tasks make the exceptions in Python script execution noticeable to IT professionals who monitor Task Schedule regularly. However, these two tasks are not necessary for downloading HTML data into a database table. The Python script itself should handle all exceptions and notify users. Windows Event Viewer is a handy tool that shows a log of application and system messages including errors, information messages, and warnings Hoffman, The tool categorizes event logs into four main groups, i.
We then enter the "eventvwr. Expand the "Applications and Services Logs" folder in the left pane. We see an extensive list of event logs in the "Operational" pane. As an example, we can find the log for the scheduled task we manually started, shown in Figure It is not convenient to view logs in this way.
Therefore, the following section creates custom event views to exclude all uninterested logs and only show specific information. Custom Views allow us to view the messages that interest us Buckell, In this case, we do not need to find these specific logs from all logs in the "Operational" list. Select "Custom Views" on the left pane. Then, on the "Actions" pane, click on the "Create Custom View…" button. A dialog should appear, as shown in Figure Switch to the "XML" tab and select "Edit query manually.
Click on the "Yes" button to continue. We copy the first query in Section 1. When using XML filtering, we can use custom views to drill through event logs and only display the information we need Pyle, Click on the "OK" button to secure changes, and a new dialog shows up to ask for more information about this custom view.
We enter the text "failed to access web page" as the name of this view and click on the "New Folder" button. Click on the "OK" button to save the folder name. Next, we select the new custom view to show the logs of interest, as shown in Figure Figure 32 View "failed to access web page" Logs in the Custom View.
We repeat the steps to create another custom view "failed to save data. After we create two custom views, the "Event Viewer" window should look like Figure Figure 33 View "failed to save data" Logs in the Custom View. We created a basic task that has a time-based trigger. The task runs the Python script at PM every day.
The Python script always throws one exception at run-time for testing purposes. We manually started the task during the development phase. We viewed the Python script execution status through the task history tab in the task scheduler and custom views in the event viewer. To ensure the solution works on the production server, we log out of the development machine and let the task scheduler run the Python script. After the task scheduler has executed the script several times, we log into the development machine to check the execution logs.
We launch Windows Task Scheduler by following the steps in Section 1. We then select the "failed to access web page" task. You need to create it first and change the values. Download the latest upx version to get file compression. Save upx. Open the spec-file and use this boilerplate settings. Just alter the directory and the name of the script. It works on every Windows machine without Python installation!
If you want to change the custom icon in the GUI you must declare it with an absolute path in your. A relative path causes an execution error after compiling. A virtual env error. Maybe you used powershell or an outdated shell. If you did everything right, after. Most likely you did not install pyinstaller in your virtual environment causing your pyinstaller in your global environment if installed before to compile all of your global packages.
If you tend to install new packages for testing purposes in your global env this can easily lead to few gb and hence takes a lot of time. Just make sure to activate your virtual env first, install pyinstaller and retry. It is a very informative site and every post was written in an easy understanding way.
