sorry mbliek i thougt there was, as far as i know now there is only one power status in Synology SNMP: good or fail (well i know when it fails :D )

i still have one other issue.

free space giving me the good status on the utility page
free space on utility.jpg
free space on utility.jpg (33.06 KiB) Viewed 7617 times
but on my room page it gives me a 0 or 1 or 2.
free space on dashboard.jpg
free space on dashboard.jpg (20.41 KiB) Viewed 7617 times
and i cannot figure out why.

here is my script (free space has IDX 45 and 46)

Could be, but it can also be possible that your system don't provide that OID....
I'm using a QNAP NAS so I don't know if they changed the OID's

could it be that the 213+ does not support system temperature?

and is this oid the only one that does not work?

Create 1 virtual switch and 3 virtual temperature sensors.
I think it needs to be
Create 1 virtual switch and 2 virtual temperature sensors and 1 virtual counter.
Also

Code: Select all

NAS_HD_SPACE_IDX="4"        # NAS HD1 Temp IDX
Needs to be

Code: Select all

NAS_HD_SPACE_IDX="4"        # NAS HD Space IDX

I have a DS213+ and can confirm the given script works also on a DS213+.

Any suggestions to get this working with DS412+?

snmpget -v 2c -c <community> -O qv <IPOFNAS> 1.3.6.1.4.1.6574.2.1.1.2

No results for a disk temperature

This does work:

snmpget -v 2c -c <community> -O qv <IPOFNAS> 1.3.6.1.4.1.6574.1.2.0

It will result the system temperature

I can confirm the temperature is still working indeed DSM 5.1.
Just installed the script.

I do get some values for the HD usage however those are not in my script.

Code: Select all

snmpget -c public-domoticz -v2c -O qv 192.168.2.12 .1.3.6.1.2.1.25.2.3.1.4.36
snmpget -c public-domoticz -v2c -O qv 192.168.2.12 .1.3.6.1.2.1.25.2.3.1.5.36
snmpget -c public-domoticz -v2c -O qv 192.168.2.12 1.3.6.1.2.1.25.2.3.1.6.36

Hi all,

I had add a monitor of CPU and Memory of my Synology with DSM 5.1.

I had this code on my nas.sh :

Code: Select all

#Variables
 NAS_MEM_IDX="55"        # NAS MEM IDX
 NAS_CPU_IDX="56"        # NAS CPU IDX

I had this code on my nas.sh :

Code: Select all

#Variables
 NAS_MEM_IDX="55"        # NAS MEM IDX
 NAS_CPU_IDX="56"        # NAS CPU IDX
 
# Free Memory Available in %
	MemAvailable=`snmpget -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.2021.4.6.0`
        MemAvailableinMo=$(($MemAvailable / 1024))
	MemUsepercent=$((($MemAvailableinMo * 100) / 1024))
        # Send data
        curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_MEM_IDX&nvalue=0&svalue=$MemUsepercent"

Maybe you can add it to the NAS wiki.
