#Intermapper no layer 2 data available software#
InterMapper is real-time network monitoring software that displays network device and traffic volume between devices in a series of maps. More information on the proper use of the TRM can be found on the You can have multiple exporters sending flow records to the single collector, though.Ĭopyright © Fortra, LLC and its group of companies.Īll trademarks and registered trademarks are the property of their respective owners.Technologies must be operated and maintained in accordance with Federal and Department security and In our first release, all the flow records must be sent to one Intermapper Flows machine (the "collector"). You can find a brief document that describes the commands at:ĭoes IM Flow act as collector at each location so that the central server can pull the data from each collector and correlate the same?
It is easy to set up your Cisco gear to send flow records, so you can see the effect on the traffic.
#Intermapper no layer 2 data available update#
The switch/router summarizes the flow information, and typically will send an update about the flows it has seen every 60 or 120 seconds (this is configurable). In Help/Systems' experience, it is often much less. According to Cisco reference documents, NetFlow consumes 5 to 10 percent of your network bandwidth, depending on your configuration. How much bandwidth will NetFlow consume? How frequent is the traffic flow?Ī quick answer is "not much". Many kinds of Cisco equipment can export flow records that summarizes the data flowing through that device. Yes, Intermapper Flows will work on any link where there's an "exporter" (the router/switch) to keep track of the traffic statistics. If you feel the file is getting too large, you can delete it safely.ĭoes Intermapper Flows work on LAN links? On WAN Links? The server logs significant information in this file. In the directory in which Intermapper Flows is installed, (see the Readme file in the installation package for a file location) there is a log file named "ns2flows.log". You can copy/paste the output of these two commands into a bug report (Help -> Report a Bug.). Use the "ext" command to check that Intermapper has its own connection to the IMFlows server. Then telnet to the Intermapper server and use the "flows" command to list the exporters that Intermapper knows about. To do this, turn on the Telnet server in the Intermapper Settings. Intermapper can provide some debug information via the Telnet server. Is there any additional information available for troubleshooting or debugging a problem with Intermapper Flows? Other times it'll fall short and finish early. Since this estimate is never perfect, you'll sometimes notice that the actual number of records exceeds the estimated records.
The NetSAW server estimates the number of flows it will load into its cache, based on the flowrate that's learned from the actual records in the DB. Sometimes the first number is larger than the second. When the Intermapper Flows server is restarting and reloading the sessions, the Flows Window displays the number of records loaded so far vs.
