-# Cisco NTP [(Download the MKP package)](/../../../-/raw/master/{REPLACE_WITH_PACKAGE_NAME}.mkp "Download MKP package")
+# Extended traceroute plugin [(Download the MKP package)](/../../../-/raw/master/active_check_traceroute.mkp "Download MKP package")
+
+This is a extension for the original CheckMK traceroute plugin (Routing)
+
+it adds the following options:
+
+- service description suffix
+- alternate destination address
+- destination port for UDP/TCP path trace
+- max hops
+- queries per hop
+- source address
+- source interface (needs root permissions)
+- perfometer
+
+**Note: Source address and source interface uses the "shell=True" option in in the "subprocess.Popen" command. This is highly insecure, so be careful.**
+
+**Note**: the original TCP path trace option also needs root permisions.
 
-Monitors status of C{REPLACE_WITH_PACKAGE_TITLE}
