QUESTION
I am trying to get the data from Google analytics Reporting API, the problem is that the first request quickly gets the data but the next request is taking around 5 mins.Does it happen because of my pagination code which is happening in while loop?
My Page Size is "300". I used this size to check my pagination.
...ANSWER
Answered 2020-Feb-26 at 18:12Sorry I'm not a python expert. You have a "sleep(1)" in your row loop, so 1 second for each row = 300 seconds per row (5 mins). that would make the most sense to me.
Try removing the sleep in your row loop.
I hope that helps.
QUESTION
We are conducting an experiment to gauge the benefits of service worker. As part of that we are recording pageLoadTime and service worker state. The idea is that the data which has controller state as activated will be treated as pages served via service worker and where service worker is not installed will have controller as null and so no service worker state. This way we can compare pageLoadTime with & without service worker.
Is this the right approach to know that the page is being served from SW? One concern that comes to mind is, if SW gets killed in between and gives us wrong info about the state. However we are recording service worker state way early in page load lifecycle as soon as our js code boots up. So at this point SW should be up & running intercepting traffic from the page. This looks to be a safe technique. Any thoughts are this ?
Another approach that comes to mind after reading PerformanceResourceTiming API on MDN is to use workerTime.
The workerStart read-only property of the PerformanceResourceTiming interface returns a DOMHighResTimeStamp immediately before dispatching the FetchEvent if a Service Worker thread is already running, or immediately before starting the Service Worker thread if it is not already running. If the resource is not intercepted by a Service Worker the property will always return 0.
As per the doc, it mentions workerTime will always be zero if SW is not there. Can there be a scenario when SW is installed and yet workerTime is zero?
As an trial, I crawled to Pinterest and queried following in Chrome dev console, workerTime is always zero though SW is there.
...performance.getEntriesByType('navigation')[0]
ANSWER
Answered 2019-Aug-20 at 19:15For your own applications, where you're in control of the code that registers the service worker, the best way to determine whether a service worker was in control of the page at load time is to check navigator.serviceWorker.controller before you call navigator.serviceWorker.register(). If navigator.serviceWorker.controller is not null that means a service worker was in control when the page was loaded.
Note, it's important to check navigator.serviceWorker.controller before registering your service worker, because a service worker can start controlling the page after it's registered (if it calls clients.claim()) but in such cases it wasn't controlling the page at load time, which is what you care about.
On my website, here's the code I use on my blog to determine the initial service worker state:
QUESTION
I'm trying to display the source property name within the Google Analytics roll up property I have linked to bigquery. Issue is, is that when I try the below some of the metrics become hugely inflated. I'm guessing this is to do with repeated fields but not sure what to do about it. I've tried a number of workarounds like using "max" but this doesn't display every property name.
All metrics except users and visits seem to be inflated.
...ANSWER
Answered 2017-May-10 at 04:28You're flattening your table in your most outer FROM statement (ie here:
FROM
project.dataset.ga_sessions_*, UNNEST(hits) as h)
All your session level dimensions eg device.* or totals.* values like totals.transactions are already rolled up to a session level, so when you flatten the table by unnesting the hits, these totals values get written as many times as there are hits. Example: Let's say there are 30 hits in one session and 2 transactions, since you flatten/unnest your hits, you will be left with 30 rows containing totals.transactions = 2, so when you sum over them, the result would be that there were 60 transactions in this session. Your users and visits don't get affected by this since you count distinct them, so any dupes get eliminated.
It looks to me as if you're query will work if you just remove the , UNNEST(hits) as h if you remove or adapt this line
h.sourcePropertyInfo.sourcePropertyDisplayName as display
since you already unnest the hits within the select statement where required apart from in this particular line.

Answered 2019-Jan-24 at 21:30oageLoadTime is by default sampled. This would explain why a lot of it is empty. You will only have that metric for dimensions where the load time is captured.
QUESTION
I want to do automated web testing with Selenium and execute JavaScript. The string func1 contains my js-function and it is passed to ExecuteScript(func1) it returns an array of objects which look like this {label:'start', time: 121}.
I want to cast the result of ExecuteScript into List
ANSWER
Answered 2018-Jun-23 at 03:34You need to deserialize the result into the required List.
- Refer the package JSON.Net from here
Deserialize the
result(assuming to be astring) as follows:List timings = JsonConvert.DeserializeObject>(result);

I'm trying to record the time from page start until a specific thing is displayed and write that time into an excel file and then do it again for x times. Right now I am able to do it each time through the loop it is overwriting everything and I am only ending up with the last result. The other problem is that it's not putting the info where I expected it to put it. I just want all of the results in the first column. I've been banging my head against this one for days trying all the options I found in SO with varying success but never getting the result I've been shooting for. Any assistance will be greatly appreciated.
