Use pprof to visualize profiling data
produced by Rprof()
or record_rprof()
.
serve_rprof(
rprof,
host = "localhost",
port = proffer::random_port(),
browse = interactive(),
verbose = TRUE
)
Path to profiling samples generated
by Rprof()
or record_rprof()
.
Host name. Set to "localhost"
to view locally
or "0.0.0.0"
to view from another machine. If you view
from another machine, the printed out URL will not be valid.
For example, if pprof()
or serve_pprof()
prints
"http://0.0.0.0:8080", then you need to replace 0.0.0.0
with your computer's name or IP address, e.g.
"http://my_computer.com:8080".
Port number for hosting the local pprof server. Chosen randomly by default.
Logical, whether to open a browser to view the pprof server.
Logical, whether to print console messages
such as the URL of the local pprof
server.
A processx::process$new()
handle. Use this handle
to take down the server with $kill()
.
Uses a local interactive server. Navigate a browser to a URL in the message. The server starts in a background process
if (identical(Sys.getenv("PROFFER_EXAMPLES"), "true")) {
rprof <- record_rprof(replicate(1e2, sample.int(1e4)))
# Start a pprof virtual server in the background.
px <- serve_rprof(rprof)
# Terminate the server.
px$kill()
}
