Browser/SPA NRQL query examples

This document will explain how you can use NRQL to query and explore your Browser data, including SPA data.

View JavaScript errors

To view JavaScript errors, you'd run a NRQL query of the JavaScriptError event reported by Browser. For example:

SELECT * FROM JavaScriptError

Here's an example of JSON resulting from running this query, which includes JavaScriptError attributes.

"event": {
  "deviceType": "Desktop",
  "firstErrorInSession": true,
  "releaseIds": "{\"jQuery\":\"v3.1.1\",\"multiverse\":\"98e7ab6\"}",
  "appName": "Book Staging Multiverse",
  "errorClass": "Error",
  "errorMessage": "Script error message",
  "requestUri": "/synthetic-multiverse/",
  "userAgentName": "Chrome",
  "transactionName": "Unnamed Transaction",
  "userAgentVersion": "44",
  "appId": 950582,
  "userAgentOS": "Linux",
  "timestamp": 1502262005,
  "browserInteractionID": ,
  "parentEventId": 
}

View sample SPA data

To run a NRQL query of your Browser SPA data, use the BrowserInteraction or AjaxRequest events. For example:

SELECT * FROM BrowserInteraction

Here are some examples of NRQL queries you can make of your SPA data. To see all Browser attributes, see Browser default attributes.

To compare the performance of page loads and route changes in the last day, at 1-hour increments:

SELECT average(duration) FROM BrowserInteraction SINCE 1 day ago FACET category TIMESERIES 1 hour

To create a data table of the average, minimum, and maximum Ajax counts for the 20 slowest route changes:

SELECT average(duration), average(ajaxCount), min(ajaxCount), max(ajaxCount) 
FROM BrowserInteraction WHERE category = 'Route change' SINCE 1 day ago 
FACET browserInteractionName LIMIT 20
