Check port links under devices or the links table in the database.
I didn’t see an API endpoint for them with a quick look, definitely could be added if anyone wanted to add it.

thanks murrant!
i just found the code about the data from Overview/Maps/Network. it locate at includes/html/print-map.inc.php. it shows 2 sqls generates the result for graph. and the link api you sent is to generate xdp network link and it used to generate network device neighbors. am i right? :wink:
other questions can you help me?

  1. what’s the difference between poller & discovery? can i disable auto exec of them and just manual exec?
  2. can i crop the image about libreNMS, we just fix on discovery. can i just keep main libreNMS and db?
    Thanks for the reply
