You can subscribe to Event Log via email by setting a scheduled task which will receive the notice of a new event and deliver it by email.

From the Task Scheduler, you start by adding a task triggered by "On an event". To subscribe to a particular Log/Source/Event ID combination, use "Basic". To subscribe to many events, use "Custom" with an event filter meeting your needs.

Either way, the second step is a powershell script which can inspect the event and forward it by email. This can be done by adding an action in Task Scheduler which calls powershell.exe and passes the agruments .\MyDelightfulScriptName.ps1 -eventRecordID $(eventRecordID) -eventChannel $(eventChannel).

To access the event that was logged, the powershell script uses Get-WinEvent with the EventRecordID filter:

1.Scheruler queue/Active requests
with self.numpages = 418.

this code lines will create 418 request objects (including -to ask OS to delegate memory to hold 418 objects) and put them into scheduler queue :

In the example, BytesIO appears to be slow due to how Python handles closing the byte stream. From the documentation for BytesIO:

A stream implementation using an in-memory bytes buffer. It inherits BufferedIOBase. The buffer is discarded when the close() method is called.

The bytes buffer is normally not destroyed until the command is issued on exit. When the Python script is finished and the environment is deconstructed, an automatic close() is issued by iobase_exit (see line 467). It can be assumed that most users just open a byte stream in the buffer and leave it open until the script finishes. Perhaps this is not the "best" way to do it, but that is how most scripts I have seen which implement io make use of it.

When new streams are called repeatedly without closing, the buffers seem to keep piling up, occasionally requiring the system to negotiate closing them at the memory limit. The limited resources of the Raspberry Pi seem to exacerbate this. This may be measurable by doing some fancy things to plot memory use as the buffer fills up, but I don't really care about it here, and it is beyond my level of experience.

This should not be the case if the SAME buffer is re-entered at a later time. The IO class is protected from this edge case by issuing a runtime error. See here. This is a separate case from what I reported in the original question, since a new buffer is generated each time BytesIO is called. It is relevant to discuss this as a misinterpretation of this section of the documentation precipitated the events described in the question.

Finally got it; I needed to re-read the doc for Chartjs. So here's the mounted function now. See that I had to put in x and y values for each point.
