@angeloaliano1 you have already asked this [question](https://discourse.julialang.org/t/query-solution-time/22263/6) ([twice](https://discourse.julialang.org/t/gap-and-cputime-in-jump-v0-19/22521/6)) and gotten a reply.

> RelativeGap isn’t implemented for CPLEX yet. I’ve opened an issue: [MOI: implement RelativeGap · Issue #228 · jump-dev/CPLEX.jl · GitHub](https://github.com/JuliaOpt/CPLEX.jl/issues/228)

In order to get it to work, you will have to implement the function in CPLEX.jl.

If you’re interested, post on the issue ([MOI: implement RelativeGap · Issue #228 · jump-dev/CPLEX.jl · GitHub](https://github.com/JuliaOpt/CPLEX.jl/issues/228)) and we can point you in the right direction for how to make the fix.
