No info in dashboard about flask-profiler HOT 9 CLOSED

FWIW I ran into a similar issue today, and it turned out to be that the "/grouped" url can be a bit long (my wsgi had a limit to 4096 characters) - so setting buffer-size=32768 in wsgi settings solved it

Hope this helps

actually you are not supposed to do anything to get summary info. I will check this.

if your database does not contain sensitive data, could you please send it here?

or could you send responses of the ajax request of the summary page?

from flask-profiler.

I've been running this in a test environment so there's no sensitive data. Here's the DB: https://drive.google.com/file/d/0B-gm7xa66enOWEFEQlJfQ2xDN3M/view?usp=sharing

As an unrelated question: what's the impact of running this on a production server?

from flask-profiler.

thanks for the db.

I downloaded and started flask-profiler with it; it works for me. I am able to see the summary info on the dashboard page.

Can you check the ajax request using chrome's developer console? And what do you get when make the request below?

http://127.0.0.1:5000/flask-profiler/api/measurements/grouped/?draw=1&sort=count%2Cdesc&skip=0&limit=-1&startedAt=1459501722&endedAt=1460020122&_=1460020122420

Yes you can use this on a production server with securing it using basic authentication. There is not any significant impact. When you are done with it, you can turn it off easily.

app.config["flask_profiler"] = {
    "verbose": True,
    "enabled": app.config["DEBUG"],
    "storage": {
        "engine": "sqlite"
    },
    "basicAuth": {
        "enabled": True,
        "username": "admin",
        "password": "admin"
    }
}

from flask-profiler.

Ok, I think that's where the problem is.

For some reason, the URL requested in my instance of flask profiler looks like this: grouped?draw=1(...), which returns an empty response. Yours looks like this: ?draw=1(...).

I found that simply adding a slash ( grouped/?draw=1(...)) returns as expected.

Hi @alejoar
I am not able to reproduce the issue so that I cannot come up with a solution.

from flask-profiler.

@muatik unfortunately I moved on to logstash to get the same kind of stats so I can't give you any more feedback for flask-profiler. I have no idea why the requested url had that difference in my server, I didn't alter the code at all.

The problem I had was that I have several servers running flask and I needed something centralized so I moved my data recollection to the load balancers.

from flask-profiler.

ohh ok, thanks anyway.

I just ran on this issue today and indeed there is a mismatch between the js ajax call to and the route declaration.

From the Werkzeug Rule documentation:

URL rules that end with a slash are branch URLs, others are leaves. If you have strict_slashes enabled (which is the default), all branch URLs that are matched without a trailing slash will trigger a redirect to the same URL with the missing slash appended.

The route declaration has a slash at the end:

@fp.route("/api/measurements/grouped/".format(urlPath))

While the ajax request don't:

192.168.21.1 - - [04/Aug/2017 18:29:31] "GET /flask-profiler/api/measurements/grouped?draw=...

This generate a HTTP 500 error with following traceback:

I manually edited(remove the slash) the flask_profiler.py in the site package and it work as expected.

By removing the trailing slash it will ensure that the route work with either Werkzeug strict_slashes enabled or not (or any other WSGI server in production).

PR #68 should to fix this issue.
