# Create network topology data dile
## PoC for creating topology_data.json from inventory data
This script creates the topology data file needed for the [Checkmk Exchange Network visualization](https://exchange.checkmk.com/p/network-visualization) plugin by Andreas Boesl and schnetz. For more information see [Checkmk forum Network Visualization](https://forum.checkmk.com/t/network-visualization/41680).
The inventory data could be created with my CDP/LLDP inventory plugins:
CDP: [CDP inventory plugin](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_cdp_cache/)\
CDP path-in-inventory: `"networking,cdp_cache"`\
CDP inventory-columns: `"device_id,local_port,device_port"`
LLDP: [LLD inventory plugin](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_lldp_cache/)\
LLDP path-in-inventory: `"networking,lldp_cache"`\
LLDP inventory-columns: `"system_name,local_port_num,port_id"`
USAGE CDP (is the default):
```
~/local/lib/topology_data/create_topology_data.py -s CORE01 -m
```
USAGE LLDP:
```
~/local/lib/topology_data/create_topology_data.py -s CORE01 -p "networking,lldp_cache" -c "system_name,local_port_num,port_id" -m
```
