okhttp - Instrumenting OkHttpClient -

-

i'm writing small wrapper library that'll allow me monitor internals of okhttpclient using dropwizard metrics: https://github.com/raskasa/metrics-okhttp.

i'm having trouble instrumenting connectionpool - specifically, periodically calling getconnectioncount() monitor number of open tcp connections.

when instance of okhttpclient created, getconnectionpool() null - i'm expecting. also, subsequent attempts access pool still return null during/after executing network requests.

i'm assuming there proper way monitor connectionpool because part of public api, i'm not seeing @ moment.

so:

  • is there way access connectionpool @ point okhttpclient.getconnectionpool() not null?
  • if isn't best approach, advice going better way?

try this:

okhttpclient client = ... client.setconnectionpool(connectionpool.getdefault());

that'll give same connection pool you'll anyway, it'll give sooner.
