Geneos X Route plugin checks the network path to a specified target node, the latency introduced by each hop and the availability of the node. It sends ICMP or TCP packets to the target host and measures the time it takes to reply and the hops that make up the full network path to the target node. The target host does not need to run any special software to provide the replies.
A number of expected routes can be preset, so that the route name is shown as a headline variable. e.g. Primary Route and Backup Route could be defined, so that when the messages are routers via the Backup Route, the operator is made aware.
X Route is also useful to ensure security, where only designated routed are considered secure.
The X Route plugin produces a single view as follows:
|targetNode||The name and IP address of the host that the route is being traced to.|
|targetState||The state of the Node - "reachable" or "unreachable".|
|totalHops||The number of hops currently used to reach the node.|
|nodeAccessTime||Time in ms for a test packet to be sent and received back from the node .|
|routeName||Shows the name of the current route. Route name can be user defined in the setup.|
|nodeName||The name of the node for each hop.|
|nodeAddress||The IP address of the node for each hop.|
|turnAroundTime||Time in ms for a test packet to be sent and received back from the hop.|
|packetLoss||The number of test packets lost as percentage of the overall sent. Indicates quality/loading of the hop.|
The following parameters can be configured for this plugin:
Specifies a comma-separated list of network interface names to be used.
On UNIX machines, interface names can be found using the command "ifconfig -a". Example names are "eth0" or "ce0".
On Windows machines, interface names can be listed by running Netprobe using the "-ifconfig" command-line option. A Windows interface name will look similar to the following:
The name of the network interface to be used to send packets (e.g. hme0). Usually the same as recvInterface parameter, but can be set to a different value in certain network configurations.
The name or the IP address of the target node at the end of the network path that is being monitored. This must not be the node that the NetProbe is running on.
Boolean. When set true will use DNS to resolve the IP addresses of the route nodes.
The type of protocol to use. Can be UDP or ICMP. ICMP is more likely to pass through routers and firewalls.
The maximum number of hops that the route can take. Maximum allowed is 63.
The maximum number of test packets sent to each hop. Maximum allowed is 7.
Routes to targetNode. The routeName headline variable shows the route used. When a route is not one of the set routes, the routeName headline variable is shown as UNKNOWN.
List of hops IP addresses or names that
describe a route. A valid value can be an IP address or a
A hop on a route. A valid value can be an IP address or a
Set this false to enable Loose Matching for the route. If Loose Matching is enabled then completely wild routeNodes (i.e. *.*.*.*) will match zero or more hops.
e.g. The Route *.*.*.*, 126.96.36.199, *.*.*.* will match any route that passes through 188.8.131.52 no matter how long.
The Source IP address to be used in the outbound test packets.
Forces X Route to detect if the underlying IP address of a host name has +changed. This will restart the packet capture engine so X Route will +continue to check the correct host. In between restarts there is a +potential for losing packets.
Note: Restarting the packet capture engine will affect all X-Set plugins as they too might miss packets
The plugin needs to open network devices, so you should run the Netprobe using root or administrator permission on and , respectively.
On Netprobe as root is
by setting the
CAP_NET_ADMIN capabilities on the Netprobe binary using the following command:
setcap cap_net_raw,cap_net_admin+eip <netprobe binary>
When running the Netprobe with set capabilities, the
lib64/startup folder in the Netprobe directory should be in
ld.so trusted paths. Otherwise, the runtime
libraries will not load properly. For guidance, see Run Netprobe under elevated privileges in Linux in Quickstart: Linux and other platforms.
: The Npcap packet capture library needs to be installed on the host. If Npcap is not installed using WinPcap API-compatible mode, then the Npcap installation directory must be added in the
PATH environment variable or the
DLL_PATH registry variable.
: The shared library
libpcap.so needs to be in the
netprobe/lib64 directory. It is recommended to use
libpcap.so version 1.0.0 or later.
Note: As the Netprobe needs to be run as
LD_LIBRARY_PATH is ignored for security
