The Geneos X Broadcast plugin monitors (UDP) broadcast traffic and displays statistics such as the data rate and packet rate, for a list of user-defined services.
The Netprobe host must be able to "listen" for the required broadcast traffic (i.e. it should be on the same network segment as the broadcast source).
The X Broadcast plugin produces a single view, with one row per configured broadcast service.
|name||The service name, as configured by the user.|
|port||The service port, as configured by the user.|
|dataRecvRate||Data received in Kb/s, averaged over the sample interval.|
|pktRecvRate||Packets received per second, averaged over the sample interval.|
|tmSinceLastPkt||Number of seconds since the last packet was received.|
|srcHost||The IP address of the host which sent the last packet.|
The X Broadcast plugin listens to all broadcast data, matching the destination ports with those configured by the user.
Plugin configuration is placed in the x-broadcast configuration section.
Specifies a comma-separated list of network interface names to monitor broadcast data on.
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 broadcast session - this is the name which will be displayed in the view (as the row name). Session names should be unique within each plugin instance.
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
