https://thl-cmk.hopto.org/gitlab/explore/projects/topics/Network%20Visualization

#########################################################################

Features of the new package:

• Create Layer 2 (CDP/LLDP) topology data
  
• Create Layer 3 (IPv4) topology data (CMK2.3.0 only)
  
• Highlight connection issues (Speed, Duplex/Half duplex, Native VLAN) (CMK2.3 only)
  
• Read connection data from the Checkmk HW/SW inventory.
  
• Works in standalone and distributed monitoring environments
  
• Add custom connections (STATIC) for connections that are not in the inventory
  
• Optimized for my CDP, LLDP and IPv4 inventory plugins
  
• Merge CDP, LLDP, STATIC topologies (CMK 2.2.0 only)
  
• Can also be used with custom inventory plugins
  

PoC for Network Visualization data creation from inventory data

This tool creates the topology data file needed for the Checkmk "Network Visualization" plugin
from the Checkmk inventory data.

THX to detlev[dot]gerke[at]siegfried[dot]ch, who was my beta tester ;-)

Features:

• Reading connection data from the Checkmk inventory
  
• Adding user defined connections for connections not included in the inventory
  
• handling differences between inventory neighbor names and checkmk hostnames
  
• optimized for my CDP (default) and LLDP cache plugins
  
• can also be used with custom inventory plugins
  
• clean up old topologies
  

For more information about the network visualization plugin see:
the announcement from schnetz https://forum.checkmk.com/t/network-visualization/41680
and the plugin on the Exchange https://exchange.checkmk.com/p/network-visualization

The inventory data could be created with my CDP/LLDP inventory plugins:
CDP: https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_cdp_cache
LLDP: https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_lldp_cache

Important:

This MKP is still a work in progress. Many things will change over time, including the format
of the raw data. When you test this package, run some tests with small configurations first.

Before you install this plugin, please read the documentation. There you will also find the
latest version.
