Netgear ReadyNAS 104 sensors setup

marius.guscius · June 15, 2022, 9:29pm

Just wanted to share my sensors config for Netgear ReadyNAS 104. Hopefully someone will find it useful.

Few issues:

Volume sizes are different in HASS and ReadyNAS admin:
Uptime is not converted to human readable relative time

WallyR · June 16, 2022, 2:33pm

You might have to add | as_timestamp after the uptime value
There might be a local version of this conversion too, but I have no access to HA here, so I can not be sure.

WallyR · June 16, 2022, 2:41pm

Regarding volume sizes, then it is probably the traditional issue with computer scientist versus engineers.
A computer scientist use 1024 for kilo, mega, giga, tera, peta and so on, while a engineer use 1000 for the same prefixes.
1 TB in computer science notation is equal to
1024 GB in engineering notation or
1024x1024 = 1048576 MB in engineering notation or
1024x1024x1024 = 1073741824 KB in engineering notation or
1024x1024x1024x1024 = 1099511627776 B in engineering notation

You need more?
This is the one i’m using, it is for 6 disks, so not sure you can use all…
but the rest should be working, all ReadyNAS’s use the same SNMP

Looks like the size was correct after all I’ve used 1024 as multiplier and it was correct one in any case, thanks!

rafalolb · December 31, 2023, 12:05am

Good job

It’s possible to get shared directories and directories sizes?

aceindy · December 31, 2023, 10:12am

I don’t think so, but you can check the database of your NAS on what is available yourself:

rafalolb · December 31, 2023, 2:02pm

How I can do that?

aceindy · December 31, 2023, 3:16pm

Do what is said in the link

SNMP MIB for ReadyNAS OS 6 devices can be downloaded directly from the management interface by going to System > Settings > SNMP and clicking on the “Download MIB” button in the SNMP settings pop-up.

I downloaded selected file. What can I do with it?

WallyR · January 25, 2025, 7:25am

The MIB file can be loaded into a MIB browser, which will give some of the entries human readable names, instead of just numbers.
