Missing 'jvm.memory.buffer-pool.usage' metric in 2.x

[kunalherkal]

When we migrated Kamon from 1.x to 2.x, we observed jvm.memory.buffer-pool.usage metric is now missing. We were using metrics for direct and mapped buffer pools. I couldn't find it in the documentation, so I assume it is either moved in some other category or it is missing in 2.x.

Is there an other way to get values of this metric in some other way or is this missing in 2.x? And if it is missing in 2.x can it be added soon?

The Kamon dependencies we use:

"io.kamon" %% "kamon-bundle" % "2.1.8"
"io.kamon" %% "kamon-influxdb" % "2.1.8"
"io.kamon" %% "kamon-prometheus" % "2.1.8"
"io.kamon" % "kanela-agent" % "1.0.7"

Other version details:

scalaVersion: 2.12.8, 
sbtVersion: 1.4.2
openjdk version "11.0.2" 2019-01-15

We missed those when upgrading :(
We'll bring them back soon! If you find anything else missing, let me know, all of those metrics should be in kamon 2.x
