NMIS integration enables the resolution of Interface indexes to Interface Names. The association to an NMIS node enables opFlow to look up the interface indexes which the traffic is flowing to and from. Note the agents are a list of the IP addresses from which flows are received. The System -> Manage Agents function enables you to associate that agent IP with an actual node in NMIS opFlow will automatically update Agent->Node links once an hour, at this time interface information will also be updated, the update can also be triggered from the GUI using System->Sync Agent/Node Data. Associating to an NMIS node enables opFlow to look up the interface indexes which the traffic is flowing to and from. You MUST tell opFlow which IP address is which Node Name for this process to work
Linking with opCharts/NMIS can be done to an NMIS instance on the same server (Local) or can integrate to a remote instance of opCharts. The server (local or remote) must not be a master instance it must be a normal poller/slave instance.

opflow_high_volume will cause opflowd to insert pre-aggregated flows if set, raw flows if not. Currently the GUI has no way of displaying raw flows so this is enabled by default.
opflow_gui_high_flow_volume will force the GUI to show a simplified/optimized index page, it can also be viewed by setting ?simple=1 on the index page, it is enabled by default.
opflow_gui_no_flows_over_time_graph will remove the flows over time graph from the index page, this is off by default.
opflow_gui_display_other tells opFlow if all flows outside of the TopN should be summarised into an "other" entry, this is off by default
Graph display settings
The graph that show flows over time can display 2 modes: the default shows the number of octets/packets in the current time slice, the second mode makes the graph display the data in octets/second or packets/second. To enable the second mode change the following config variable to 1:
