SNMP monitoring Synology NAS

[Lichtschilder]

hi all,

as a new user of Domoticz i thought it would be nice to integrate monitoring my NAS in Domoticz.
have found the Wiki page: http://www.domoticz.com/wiki/NAS_Monitoring#Synology

when following this method i get some results but can't seem to be able to get a few meters working.
anyone here who has any tips?

tried to search first but haven't found a tip yet.

currently running:
domoticz: Version: 3.4834
Synology DSM 6.0.2

have tried both changeing the .36 to .38 in the script.. didn't work yet?


working:

on/of switch
temperature 1 and temperature 2
CPU status

not working:
disk counter
disk %
ramp%


any one with a suggestion? help would be appriciated by this newbie

I have this working with two synology systems: DS110j (DSM 5.x) and DS214+ (DSM 5.x)

This is my complete script for the DS110j (one harddisk):
