patrice huot updated TINKERPOP-2288:
------------------------------------
Description:
I am using .Net core Gremlin API query Cosmos DB.
>From time to time we are getting an error saying that no connection is
>available and then the server become unavailable. When this is occurring we
>need to restart the server. It looks like the connections are not released
>properly and become unavailable forever.
We have configured the pool size to 50 and the MaxInProcessPerConnection to 32
(Which I guess should be sufficient).
To diagnose the issue, Is there a way to access diagnostic information on the
connection pool in order to know how many connections are open and how many
processes are running in each connection?
I would like to be able to monitor the connections usage to see if they are
about to be exhausted and to see if the number of used connections is always
increasing or of the connection lease is release when the queries completes?
As a work around, Is there a way we can access this information from the code
so that I can catch those scenario and create logic that re-initiate the
connection pool?

I would like to be able to monitor the connection usage to see if they are
about to be exhausted and to see if the number of used connection is always
increasing or of the connection lease is release when done with it?
As a work around, Is there a way we can access this information in the code so
that I can catch those scenario and have code that re-initiate the connection
pool?
