Critical Alerts to IT Team

I've been asked to create an escalation workflow to send a critical alert notification to our IT Team. I will be looking for certain keywords like “Network error”, “not working”, etc. I've got that part. I need to identify these issue types repeated during a certain time period. If these conditions are met, I would execute a notification sending a message to our IT Team. For example if we receive 10 network errors within an hour, I would send the notification to IT. My challenge is how to keep track of these occurrences with specific thresholds and believe that I would execute an automation since it is time-based. Any recommendations on how to have a counter to see if these conditions exists, if so take the appropriate action. If not, reset the counter back to zero. I've been analyzing on the best practice how to approach this workflow. Any help would be greatly appreciated. Thank you!
