Canvas Monitor App shows the "Duration" for running a Flow much larger than Flow runtime details

[gmanasseh]

Hello,

While trying to monitor the slow performance of a certain Action in my Canvas App, I'm not able to understand the exact cause of it. The OnSelect action calls a Flow several time. The Flow calls a Custom Connector API that retrieves data from MongoDB.

When monitoring the Flow runtime, it shows execution is complete in milliseconds. However the Canvas App Monitor is showing that the Run operation for that Flow is much more in 14 sec, 3 sec, 4 sec.. 

Appreciate any guidance on resolving this issue. 

Attached the print screens from Flow runtime as well as Monitor Details.

Thank You

The runtime in app monitor is an overall time for the app to send a request, process and complete the request. 

The flow runtime is specific to runtime of that particular flow. So you may always see the numbers high in app monitor over the flow runtime.

Hi @gmanasseh 

Looks like the issue or the slowness on the Power Automate which has some important action is going on. In general, the custom connector has slowness compared to other OOB connectors.

In this case, we need to analyze,

1. Power automate each step/action (Power automate steps has execution time like below)
2. MongoDB monitor

MongoDB also has a built-in monitoring tool to verify the query and I/O performance

Thank you avootla1 and StalinPonnusamy for your replies. 

So, I'm trying to understand what caused the time to be high for the given request.. 

If I look at the runtime app monitor details regarding a one of the flow details, I get the following details:

"startTime": 7958574.8,
"name": "https://europe-001.azure-apim.net/invoke",
"fetchStart": 7958574.8,
"domainLookupStart": 7958574.8,
"domainLookupEnd": 7958574.8,
"connectStart": 7958574.8,
"connectEnd": 7958574.8,
"secureConnectionStart": 7958574.8,
"requestStart": 7958576.9,
"responseStart": 7960435.8,
"responseEnd": 7960437.6,
"transferSize": 623,

I understand that it needs time to send a request, process it and complete it. But which of these is the bottleneck in my case so I will be able to resolve it.

I know that the since the Flow runtime is fast, it means the Customer connector is fast and there is no problem in the server where the API is hosted.

Attached details from the Powerautomate flow details, that shows it finished in 1 sec or less. For all the Runs of the Flow, the details are similar, so I'm assuming the mongodb is not the cause.

The request size and response size are relatively small. 

The time details show that the time is between the requestStart and responseStart. Does this mean anything?

Any insights would be helpful.

Thanks Again
