'show ip ospf neighbors detail' really slow on switch with many ospf neigbors

[frdaigle]

Parsing the command will last about 14 minutes on a switch with about 230 ospf neigbors.

I had a look parser's code and a 'show run | section router ospf {instance}' is run for each neighbor to gather vrf data. I would be more efficient to run a 'show run | section router ospf' once and refer to the returned dictionary for all neighbors.

Hi frdaigle,
Please can you share the cli sample output for the "show run | section router ospf {instance}".

Hi,
Ticket heading and problem statement both are different. Could you please clarify whether you are looking for the API for show run | section router ospf {instance?, and for Which OS / Device model ?

And , also would be good if you can share the reference logs (manual) to analyze further data to cross check. Are the system CPU/memory status only peaks when executing these cli`s ?

Opened PR #780 to address this issue. Testing showed that the time it took to parse the command went from 14 minutes down to ~1 minute with the optimized parser.
