The interval of “PT10S” (10 seconds) is chosen to ensure that the retry attempts are spaced out within the one-minute window. If you set the interval to “PT60S” (60 seconds), it would only allow for one retry attempt per minute, which wouldn’t meet the requirement of up to 5 attempts within one minute.

Agreed. PT10S means a 10 second delay between each try defined as the retry value.

Hi, I don't understand why PT10S is the correct answer. The function could fail immediately and the printer only accept 5 requests in 1 minute. If you set 5 retries with an interval of 10 seconds, you will have 6 requests in 1 minute?

you have to also consider the time of executing the printer request, say printer timed-out in 0 seconds and first attempt issued, say the printer timed-out in 10 seconds, then request would wait 10 seconds before trying again, so the second retry attempt would be in the 20th seconds, so it will be less than 5 attempts in 1 minute.

it will only retry 5 times and then fail and not going to retry anymore. So no 6 times in a min.

Currently it is 10, because fail after 10 min. we should increase the time interval and I am not sure to choose PT30 or PT60

If you read the following: https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-exception-handling#fixed-interval pt60s = 60s delay between each attempt. PT10s will be the better answer, 5 attempts with each 10 seconds delay satisfy the requirement “The label printer must only receive up to 5 attempts within one minute”.

Don't understand this, when PT10S => 5 times (10 sec timeout + retry after 10 sec) = total 100 seconds ? So not 60 seconds which is the requirement

Correction it is 5 times after the first attempt. So actually 6 times 20 seconds is total 120 seconds. So it will never exceed the 5 times retry in one minute. It will do 3 retries in 1 minute which is allowed according to the requirement

Fixed + PT10S, 5. None and default do not require "interval" parameter. Exponential requires additional parameters. "Fixed" is the only option that fits the schema. PT10S means that after the timeout occurs, the logic app waits 10 more seconds and tries again. It means that there will be up to 3 attempts in a minute. That fits the requirement. Extended interval does not make sense here from the user experience perspective. It is more desirable to reduce the time interval. As well as setting more than 5 attempts does not make sense. If printer cannot recover after 5 attempts it's not make sense to continue trying.

Answer to address or fix the issue.So the time interval increased to 60 seconds and for 5 attempts.As problem stated for the given fixed values its giving an error.To overcome this we need to increase the retry time .

I guess interval should be PT10S. “The label printer must only receive up to 5 attempts within one minute”.

One minute is 60 seconds - so it won't be 5 attempts... lol

https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-exception-handling#fixed-interval "This retry policy attempts to get the latest news two more times after the first failed request with a 30-second delay between each attempt:" "retryPolicy": { "type": "fixed", "interval": "PT30S", "count": 2 } Back to our case: PT10S and 5 attempts means : 1st attempt plus 5 more. That is 60seconds in total.
