When New Email Arrives - Flow Strange Behavior

Report

Posted on by Community Power Pla... Microsoft Employee

Hi,

Background: We developed a solution to monitor system alerts via Outlook. These alerts are composed of two (2) categories, PROBLEM and RECOVERY. Basically, a monitoring system will send an email alert whenever a system is down; it will also send an email when the same system recovers. These emails are sometimes almost received at the same time, so we put a delay time of 10-minutes on the processing of RECOVERY emails to prioritize PROBLEM emails.

Issue: Even if we put a delay on RECOVERY email process, the PROBLEM email process was still processed after RECOVERY.

Case:

1. PROBLEM email received time: 5:40AM

- Flow Start Time: 6:10AM

- Flow End Time: 6:10AM

2. RECOVERY email received time: 5:54AM

- Flow Start Time: 5:56AM

- Flow End Time: 6:06 AM (with 10 minutes delay)

Facts:

1. PROBLEM flow - When New Email Arrives with subject PROBLEM -> API

2. RECOVERY flow - When New Email Arrives with subject RECOVERY -> Delay 10 Minutes -> API

3. 15 minutes flow - Recurrences every 15 minutes -> API

4. The monitoring system checks more than 10 systems composed of several hosts. Each hosts have several services.

5. Emails has the possibility to receive surge/spam alerts from the monitoring system.

- <host1>/<service1> is <problem status> -> <host1>/<service1> is <recovery status>

- <host1>/<service2> is <problem status> -> <host1>/<service2> is <recovery status>

- <host1> is <down status> -> <host1> is <recovery status>

Questions:

1. Will changing the Flow Plan to either Plan 1 or Plan 2 change the processing of these flows?

2. How can we optimize the flows to handle surge emails, since there is also a plan to increase the systems being monitored?

Regards,

Syd

Hi @Anonymous ,

How is your flow created? Could you share a screen shot?

After the trigger “When a new email arrives” there is an action API, are they in the same configuration for each situation?

The maximum flow frequency for Flow 1 is 3 minutes, for Flow 2 is 1 minutes. Which plan are you using?

According to your description, I have created a simple flow likes below for your scenario. I suggest use a Switch case in the flow so that it could do the following actions under different situations.

Best regards,

Mabel

Hi @v-yamao-msft,

Thank you for your response and apologies for the late response.

Please see below screenshots of the flows I'm using.

As seen from the screenshots, we almost have the same idea. However, I separated them on purpose to easily track the logs between two status; and since there are times that the incoming emails surges.

The maximum flow frequency for Flow 1 is 3 minutes, for Flow 2 is 1 minutes. Which plan are you using?
- We are only using the Free Plan as of this moment, but we are looking into using Flow 2. We just need to verify with you guys, whether this would affect the behavior of the Flows.

I mentioned on my inquiry that we also have a 15 minutes Alert Flow (Please see below image). Will this affect the other flows, like in terms of Flow Plan and behavior?

Regards,

Syd

Hi @Anonymous ,

Thanks for updating.

The flow triggered by Recurrence (which you have a 15 minutes alert) won’t be affected if you change flow plan from Free to Plan2.

Best regards,

Mabel
