add ONU check items to the OLT template
permission to ask, is there anyone here who has complete documentation regarding ONU monitoring, a little I explain in picture A I tried to add an item and there are several parameters that have been filled in especially in the formula section I got it from the gpt chat but I don't trust it because there are several things that must be adjusted, then in picture B I tried to get velue and generated an error code and I'm stuck here, maybe friends who have experience can share or directions related to my configuration that need to be directed, thank you.
