API Request, disappearance of data

[bastien_tebbani]

Hi everyone,

I have a question, did you know why my request didn't return any data after few hours after end of an error? Here startDate is equal to the Timestamp in the begin of a specific error and endDate is the end of this specific error, applicationID is the ID of application receive with endDate and startDate when we interrogate Problem API . If data have a long duration of the lifetime, why evening I can't get information of impact of a specific error which had takes place the morning of same date?

Request :

SELECT count(*) as count, userAction.name as name, userAction.targetUrl as targetURL, applicationType, matchingConversionGoals , bounce, userAction.apdexCategory AS apdex

FROM userSession

WHERE totalErrorCount > 0 and userType = "REAL_USER"

AND userId = null

AND ((startTime <= " + startDate + " AND endTime >= " + endDate + ")

OR (startTime <= " + startDate + " AND endTime <= " + endDate + ")

OR (startTime <= " + endDate + " AND startTime >= " + startDate + " AND endTime >= " + endDate + ")

OR (startTime <= " + endDate + " AND startTime >= " + startDate + " AND endTime >= "+ startDate + " AND endTime <= "+ endDate +"))

AND userAction.internalApplicationId=\" " + applicationID + " \"

GROUP BY userAction.name, userAction.targetUrl, applicationType, matchingConversionGoals, bounce, userAction.apdexCategory

ORDER BY count(*) desc

Thanks.

Did you set the startTimestamp and endTimestamp appropriately to avoid the default of the current time minus 2 hours being used?

Hi,

In my app you can choose an interval to check every errors that may have taken place during this time slot.
You choose one specific error afterwards. The app interrogates Dynatrace API to find startTime and endTime of this error. I use both of these values to set startTimestamp and endTimestamp variables.

My question is : Why when I interrogate Dynatrace API for a specific error with specific startTimestamp and endTimestamp I "lose" userSession impacted after a certain amount of time ? For example, I may have 500 userSession impacted at 10 am, 300 at 2pm and 0 after 6pm.
If I'm not wrong, in my previous example, at 2pm I should have a number of userSession impacted greater than or equals to 500 because I already received 500 at 10 am.

Thanks.

I would try setting the startTimestamp to midnight of the current date and set the endTimestamp to "now" to see if that helps. I think your window might be too small.
