simmer.mon provides monitoring backends that can be attached to simmer, the Discrete-Event Simulation (DES) package for R, to replace the default in-memory monitor:
monitor_dbi(): inserts monitoring values into a database (viaDBI), with some in-memory buffering to improve performance, but it's still very experimental and it can be greatly improved.
The installation from GitHub requires the remotes package.
# install.packages("remotes")
remotes::install_github("r-simmer/simmer.mon")
