Notification that the user has not logged in to VK?

Question

In contact with

I have not yet figured out how to implement it, so I added a lot of tags.
The bottom line is that I have several dozen VK accounts that should go to VK every day.
They enter using a program that runs 24/7 on the server.
I'm tired of following them manually.
The problem with the program is that after restarting it, it can hang on the update, until you update it, it does not work.
So I need a way to keep an eye on a bunch of accounts at the same time as some get freezes.
In general, I need a way to send me a notification if the bots have not logged into VK before 7 am.
So that you can go to the server and correct the situation.

In general, I need a way to send me a notification if the bots have not logged into VK before 7 am.

I think it will look something like this:
0. Open this page , find the "online" field there, it is responsible for whether the user is online or not
1. Run the cron script, at 7:00 in the morning, which checks whether the user is online or no
2. If not, the script sends SMS/Email/etc to the right
place Or are you not talking about that?
