In pingr: Check if a Remote Computer is Up

Check if a port of a server is active, measure response time

Description

Check if a port of a server is active, measure response time

is_up() checks if a web server is up.

Usage

ping_port(
  destination,
  port = 80L,
  continuous = FALSE,
  verbose = continuous,
  count = 3L,
  timeout = 1
)

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

Arguments

destination	Host name or IP address.
port	Port.
continuous	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.
check_online	Whether to check first if the computer is online. Otherwise it is possible that the computer is behind a proxy, that hijacks the HTTP connection to destination.

Value

Vector of response times, in milliseconds. NA means no response within the timeout.

Examples

ping_port("r-project.org")


is_up("google.com")
is_up("google.com", timeout = 0.01)
