sentryR is an unofficial R client for Sentry.
It includes an error handler for Plumber for uncaught exceptions.
You can install the latest development version of sentryR with:
# install.packages("remotes")
remotes::install_github("jcpsantiago/sentryR")or the stable version in CRAN with:
install.packages("sentryR")configure_sentry and capture are the two core functions of sentryR.
The first sets up an isolated environment with your Sentry project's DSN,
optionally your app's name, version and the environment it's running in.
Both configure_sentry and any of the capture_ functions accept
additional fields to pass on to Sentry as named lists.
NULLifying a field will remove it.
library(sentryR)
configure_sentry(dsn = Sys.getenv("SENTRY_DSN"),
app_name = "myapp", app_version = "8.8.8",
environment = Sys.getenv("APP_ENV"),
tags = list(foo = "tag1", bar = "tag2"),
runtime = NULL)
capture(message = "my message", level = "info")You are encouraged to use the two wrappers around capture included:
capture_exception, which handles the error object and then reports the error
to Sentry, and capture_message for transmitting messages.
Refer to the Sentry docs
for a full list of available fields.
By default sentryR will send the following fields to Sentry:
list(
logger = "R",
platform = "R", # Sentry will ignore this for now
sdk = list(
name = "SentryR",
version = ...
),
contexts = list(
os = list(
name = ...,
version = ...,
kernel_version = ...
),
runtime = list(
version = ...,
type = "runtime",
name = "R",
build = ...
)
),
timestamp = ...,
event_id = ...
)capture_exception further adds the exception field to the payload.
In a Plumber API, besides the initial configuration for Sentry, you'll also have to set the error handler.
sentryR ships with the default plumber error handler wrapped
in the convenience function sentry_error_handler, but you can use
your own function and wrap it as below:
library(plumber)
library(sentryR)
# add list of installed packages and their versions.
# this can be slow in systems with a high number of packages installed,
# so it is not the default behavior
installed_pkgs_df <- as.data.frame(utils::installed.packages(),
stringsAsFactors = FALSE
)
versions <- installed_pkgs_df$Version
names(versions) <- installed_pkgs_df$Package
packages <- as.list(versions)
configure_sentry(dsn = Sys.getenv('SENTRY_DSN'),
app_name = "myapp", app_version = "1.0.0",
modules = packages)
my_sentry_error_handler <- wrap_error_handler_with_sentry(my_error_handler)
r <- plumb("R/api.R")
r$setErrorHandler(my_sentry_error_handler)
r$run(host = "0.0.0.0", port = 8000)and wrap your endpoint functions with with_captured_calls
#* @get /error
api_error <- with_captured_calls(function(res, req){
stop("error")
})once this is done, Plumber will handle any errors, send them to Sentry using
capture_exception, and respond with status 500 and the error message.
You don't need to do any further configuration.
You can also use sentryR to capture exceptions in your Shiny applications
by providing a callback function to the shiny.error option.
library(shiny)
library(sentryR)
configure_sentry(dsn = Sys.getenv('SENTRY_DSN'),
app_name = "myapp", app_version = "1.0.0",
modules = packages)
error_handler <- function() {
capture_exception(error = geterrmessage())
}
options(shiny.error = error_handler)
shinyServer(function(input, output) {
# Define server logic
...
}sentryR took inspiration from
raven-clj a Clojure interface to Sentry.
