  verbose = continuous,
  count = 3L,
  timeout = 1
)

is_up(
  destination,
  port = 80,
  timeout = 0.5,
  fail_on_dns_error = FALSE,
  check_online = TRUE
)

Arguments

destination

Logical, whether to keep pinging until the user interrupts.

verbose

Whether to print progress on the screen while pinging.

count

Number of pings to perform.

timeout

Timeout, in seconds. How long to wait for a ping to succeed.

fail_on_dns_error

If TRUE then is_up() fails if the DNS resolution fails. Otherwise it will return FALSE.
