linux_if

Linux network monitoring plugin with support for bonding and vlans.

Plugin will group all bonding slaves into one aggregated graph. It removes clutter of having many single-metric graphs for individual interfaces. You still can click through to individual graphs.

In this example, p1p1, p2p1 are physical interfaces of one bond0. Only p1p1 is active, as we are using Active-Backup bonding mode. Total (black) is the throughput of parent interface bond0.

Similar aggregation is done also on higher level for vlans. All vlan sub-interfaces are aggregated into one graph, based on their parent interface. Interfaces do not even have to follow the same naming convention (interface.vlanid). Interfaces bond0.279, vlan101, vlan102 are all vlan sub-interfaces of bond0.
