You can use '/misc/ping' route to check if pgAdmin4 is running.

Example: http://localhost:5050/misc/ping

On Success you will get,

Status code: 200

Response text: PING

Hi,

we are using pgadmin in a docker container on aws. To ensure that the container is up and running, a healthcheck is periodically checking via http, restarting the container if neccessary.

When checking the filesystem, we found that for each request, a session file is created. Healthcheck is done twice every 30secs, so we have about 5600 session files a day. (about 100k after a few days..)


I looked at the sourcecode and found that in session.py, line 259 it looks like cookies should not be created for static resources

-

def open_session(self, app, request):
cookie_val = request.cookies.get(app.session_cookie_name)

if not cookie_val or '!' not in cookie_val:
# Don't bother creating a cookie for static resources
for sp in self.skip_paths:
if request.path.startswith(sp):
return None

-

unfortunately, in __init__.py, when setting up the session interface, skip_paths is empty and so a cookie gets created also for static resources (i'm no python hacker, so maybe i'm missing something)


So my question is - is there an url that can be used for healthchecking, that does not create a session file on every check ?


thanks a lot,
