CMTS SNR, RX Power, Microreflection per CM

[Stefan_1982]

Hello Cacti Users (Sorry for my Bad English)

i already made a few SNMP Indexed Devices and the worked very good.
But now i wan't to get special Data from an CMTS.

I will get the SNR Microref... and the Receive Power of every CM on the CMTS.
Not only the current online modem also the new one.
I now there are many CMTS Templates for Cacti but there is always the amount for all CM's.

i have a big problem because i can't use a indexid.
1) there is no indexid
2) every reboot of the CMTS the indexid would chance if there is one.

So i think i must make <oid_index_parse> with the MAC address or IP Address of every CM.

I think this should work but this is only for that CM how are online when i make the Querie

So do anyone know a better way for that.

Here you can see the SNMP Data of my test CMTS

Thanks for Help

Sounds like you're going to need to create a custom script (I'd recommend php script server) which can associate a fake index of an IP address to the index the CMTS has used it.

basic info on the howto in the doc site.

Hello THX for the answer,
Sounds very complex, don't know if i can make this.
I'll try it on weekend.
