Among other things, I’m monitoring 2 geographically separate 7342 ISAM deployments. One has 3 OLT shelves, the other has 7 OLT Shelves. Polling takes forever. I’m still pretty new to Libre. I need to slim it down a lot. We have a similar issue with monitoring/polling our Calix E7-2 shelves, which is similar in functionality.
I don’t have a suggestion for you, but I’m looking for some recommendations myself. Right now, I’m going to just add the shelves as Ping Only device. Eventually I’ll turn on selected port polling and enable the important ports.
