writeCounter increasing more than N in Y duration

come up with an alert query that will allow a user to specify that if the writeCounter increases more than N in Y duration an alert will fire.

This will need to be tested that it does fire when expected.

Also some details on potential causes, and how to investigate and troubleshoot.

Start by locating writeCounter and any existing alert queries or alert tests in the repository. Define how users specify N and Y, verify the alert fires when the threshold is exceeded, and document potential causes plus investigation and troubleshooting steps.
