What commands to get some logical KPI via Python.

Hello,

I'm trying to get some logical KPI of some NE40E routers via python to later graph them, the initial data for parsing are the Estimated Max Entries And Current Usage for the next KPI:

• MPLS Label - display mpls label all summary -  - display mpls ldp lsp statistics

• vpn-instance      

• Ipv4 Routes - display fib slot 1 statistics all

• Vpnv4 Route - display bgp vpnv4 all routing-table statistics

• Vpnv4 By Prefix or Vpnv4 by Vrf - display ip routing-table all-vpn-instance      statistics

• FEC

• TCAM

• Longest Prefix Match

• Fast-forwarding.

As mentioned before, I was only able to get the data with the referenced commands, but I don't know which commands to use to get the other KPIs, like:

• What command to get how many vpn-instance support the NE40E.

• What  command to get the Estimated Max Entries of Vpnv4 Route.

• What command to get the Estimated Max Entries and Current Usage of Vpnv4 By Prefix or Vpnv4 by vpn-instance.

• What command to get the data for FEC or equivalent.

• What command to get the data for TCAM or equivalent.

• What  command to get the data for Fast-forwarding (Cisco CEF) or equivalent.

• In  cisco there is a concept like (Longest Prefix Match Database) and (Large Exact Match Database) Are these available in Huawei or any equivalent?

Thanks in regards.
