    @bluesmoon No problem ended up writing a c# parser for jsurl
    @bluesmoon or well anyone does boomerang have a clear cut way to grab time to first byte(TTFB) I know we can sort of extract this from resource timings but just wondering if any plugin already carries it?
    Or well I guess I can just use t_resp: Time taken from the user initiating the request to the first byte of the response.

    t_resp is the same as first byte time.

    Hey guys, I am playing with boomerang for the first time and I am wondering why it doesn’t send anything to boomcatcher. I can see console.logs in the browser console and I specified beacon_url … also when I run BOOMR.sendBeacon() I can see that something is sent… but metrics are not sent by themselfs. Any idea what am I doing wrong?
    I use these plugins:
        <script src="bower_components/boomerang/boomerang.js"></script>
    <script src="bower_components/boomerang/plugins/spa.js"></script>
    <script src="bower_components/boomerang/plugins/angular.js"></script>
    <script src="bower_components/boomerang/plugins/auto-xhr.js"></script>
    <script src="bower_components/boomerang/plugins/clicks.js"></script>

    Managed to get Clicks plugin working. I am wondering why it doesnt load beacon_url from the main config.
    Philip Tellis
    @bluesmoon
    I don't believe any of those plugins have anything that can be auto sent
    The rt.js does call BOOMR.sendBeacon, so that one should be added
    maybe navtiming.js too

    @MartinNuc
    ah I will check that out. Thanks.
    Martin Nuc
    @MartinNuc
    I will dive into spa and angular plugins later. I made working Clicks plugin.
    Martin Nuc
    @MartinNuc
    I am curious - boomerang records events but it doesnt send them to the server. Why is it so? For what are metrics when they are not stored anywhere?
    what is the philosophy behind this?

    Hi everyone,
    I was wondering if it's possible to send a "start" beacon that will always be fired first. I'm trying to batch xhr calls manually since the autoxhr plugin isn't working as expected (could be the framework we are using).
    Thanks
    Philip Tellis
    @bluesmoon
    @MartinNuc you're required to either use a plug-in that calls sendBeacon, or to call it from your own code.

    I have a fairly complicated angular app that I'm trying to log performance data for and I'm finding it very difficult to group the beacons together that were spawned from a single click event so that we can easily report the RUM time. I did find a "cl" timestamp that is stored in the "RT" cookie (e.g. "nu=[url]%2F&cl=1536867262470") that seems to give me the ability to group a bunch of xhr requests together. Is there a better/easier way to do this?
    One more question too: Can I configure how the beacon params are named? I am sending the params to a grails app and auto-binding the beacon params to a command object which only works if the params are valid variable names(so no periods). My workaround for this is to duplicate the beacons params in the "before_beacon" event that have periods in the key names and replace the period with an uderscore.

    @bluesmoon awesome profile pic btw

    Anybody out there?

    All go ahead and add another question: is there a way to get more user agent information. For example all I get for Chrome is : Win32 and Google Inc
    for IE 11 I just get Win32
    Philip Tellis
    @bluesmoon
    @mitchmckenzie for user agent information you should look at the User-Agent HTTP request header on the server side when you receive your beacon. It has all the information you need.
    regarding your app, you should not have multiple beacons for a single click event if page changes and XHRs happened close enough together.
    Mitch McKenzie
    @mitchmckenzie
    "regarding your app, you should not have multiple beacons for a single click event if page changes and XHRs happened close enough together." Not sure why you say that because I see apps fire multiple xhr request all the time as a result of a single click
    Philip Tellis
    @bluesmoon
    That's not the way it's designed to work, so it's possibly a bug. What should happen is that if an XHR happens soon after a click, then it gets clubbed in with that click. If DOM mutations or XHRs happen soon after this XHR, then they also get clubbed together, and finally, if there are no changes for a short duration (500ms IIRC), then a single beacon is sent that covers all these XHRs and DOM mutations.
    If that's not happening, then I'd say it's a bug
    Mitch McKenzie
    @mitchmckenzie
    Perhaps but when I report on the data I can roll those up into a single measurement
    Mitch McKenzie
    @mitchmckenzie
    Are the beacons posts asynchronously so they do not interfere with the page?
    Philip Tellis
    @bluesmoon
    yes, it uses the Beacon API where supported or async XHR where not, and falls back to an IMG if cross-domain async XHR is not supported

    Hi guys,
    I'm trying to use boomerang for painting monitoring, but there are no paint timing metrics in the beacon request. Can somebody help me with PaintTiming plugin?
    Mitch McKenzie
    @mitchmckenzie
    Is there a way to kill the console debug output from BOOMR?
    Mitch McKenzie
    @mitchmckenzie
    nevermind figured it out from the source code: log:null in the config does the job
    Mitch McKenzie
    @mitchmckenzie
    Is there a way to log the request bodies of the request using boomerang?
    Philip Tellis
    @bluesmoon
    are you referring to the beacon request body or some other request body?
    Quinten Pohl
    @quintenp
    Probably XHR bodies
    And yes it's possible and quite easy using the autoxhr plugin
    Philip Tellis
    @bluesmoon
    we don't log those (because it would be very bad for performance)
    but you could easily add your own log statement
    Quinten Pohl
    @quintenp
    Given that you add the code yourself
    Philip Tellis
    @bluesmoon
    yeah
    Quinten Pohl
    @quintenp
    Bad practise since you could easily log pci data which can net you serious issues since the GDPR laws
    Mitch McKenzie
    @mitchmckenzie
    @bluesmoon : For a given request that the auto-xhr plugin handles ... I want the beacon data to include the body of the request (aka the request payload) , in my case it will be a blob of JSON data
    Quinten Pohl
    @quintenp
    @bluesmoon ever thought about using fetch api
    Mitch McKenzie
    @mitchmckenzie
    I want the data so I can scrap it out later for reporting purposes
    Quinten Pohl
    @quintenp
    So fetch ->sendBeacon->she
    Xhr
    Mitch McKenzie
    @mitchmckenzie
    not sure I follow
    Quinten Pohl
    @quintenp
    Not relevant to your ask @mitchmckenzie
    Mitch McKenzie
    @mitchmckenzie
    ok
