libriemann-client-dev 1.9.1-1 (i386 binary) in ubuntu bionic

 The riemann-c-client library provides a C language client, with a
 simple but convenient API, to connect to Riemann, send events and run
 queries against it
 .
 This package is needed to compile programs linked against
 librliemann-client0, as only this includes the header files and
 static libraries needed for compiling.
