This is what I have, and some more for comparison, which works for me.

            #HDFree=$((($HDTotal - $HDUsed) * $HDUnit / 1024 / 1024 / 1024))

            # Free space volume in percent
            HDTotal=`snmpwalk -c $PASSWORD -v2c -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.5.36` # Change OID to .38 on DSM 5.1
            HDUsed=`snmpwalk -c $PASSWORD -v2c -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.6.36`  # Change OID to .38 on DSM 5.1
            HDFreePerc=$((($HDUsed * 100) / $HDTotal))

This should be working for you, or at least test the snmpwalk commands individually.

For my DS214play with DSM 6.0 the .36 didn't work correctly, had to change it to .41
This is my storage descriptor table, as you can see .36 is my /tmp

Code: Select all

Name/OID: hrStorageDescr.1; Value (OctetString): Physical memory
Name/OID: hrStorageDescr.3; Value (OctetString): Virtual memory
Name/OID: hrStorageDescr.6; Value (OctetString): Memory buffers

I am trying to get this to work. But the storage is always showing 0 (both the percentage and the normal one).
I have a DS216+ with DSM 6.0.1.
Also installed SnmpB on my Windows laptop to see the tree of my NAS and I can go up to 1.3.6.1.2.1 but then I am not able to find 25..
Can someone help me?

Good afternoon everybody,

i saw this awesone script. Andy i was wondering if i could manage my synology with domoticz. Within domoticz i already have added the motherboard sensors and with these i can see my CPU en Memory percentage. So i did the steps according to the wiki for a setup for my 4 drive NAS (Synology DS916+ 8GB), did the chmod and tried to test the script. And it stucks on the line to ping my NAS. I receive a syntax error on Pingtime. When i try to execute it directly from putty i receive the ping time.

I tried it without the ping part but then it directory stucks on the next line. So my question is, is it possible to run this script on domoticz which is installed as a package on the synology i want to monitor.

any suggestions?

I have done some investigating and when i use bash i get the script to run. But it stucks on snmpget, he doesn't know this command. when i try snmpwalk from the putty commandline i'll get the temperature of the disk. So the script is actually working.

But the issue is that on my synology snmpget isn't available. Is it possible to install/include snmpget on my synology so the command can be used. Or is there an other way to get it executed the way it should be.

A view days ago i asked some questions but onfortunately no reactions. In the mean time i was able to get the temperature from my 4 NAS disks and put it into domoticz. But i struggle with the space en mem. Those counters don't give the right information.

Anyone?

I changed all snmpget commands in the bash script itself to snmpwalk one-by-one on my Synology, then it started to work (again). I stated this a few posts earlier also with some example script piece.
Provided that you are running the script on the Synology box itself of course :)
This way you do not have to install anything.
I'm not sure why this has changed on the Synology boxes.

Very nice topic, thanks a lot rvmourik, it's working well with my APC ES700 and DS412+ / DSM 6.02 ;)
I retrieve infos like: input voltage, charge, runtime, battery voltage, ... it was quite long to get good informations lol.
The script uses input voltage to give me an alert "no current - battery mode" (with an mail notification every 5 minutes)
So fun ;)

Hi everyone,

i got the disk temperature up and running, that wasn't a big part.
The used GB in % is a part of the motherboard sensors so i could add that easy as well (i run domoticz directly on my synology)

Now i am trying to get the available space in GB and % get to work, but i am still stuck in de /1024 /1024 part. With snmpget or snmpwalk i receive an error that is 'kb' and there is missing a ')'

Anyone got this already working and would share this here?

From cmdline try this command, replacing COMMUNITY and NASIP with your values:

snmpget -v 2c -c COMMUNITY -O qv NASIP 1.3.6.1.2.1.25.2.3.1.4.41
or
snmpget -v 2c -c COMMUNITY -O qv NASIP 1.3.6.1.2.1.25.2.3.1.4.38

and post the result.

Excuse for the delay, i had a short holiday break :-)
Here is the output

1.3.6.1.2.1.25.2.3.1.4.41
No Such Instance currently exists at this OID

1.3.6.1.2.1.25.2.3.1.4.38
4096 Bytes

Extra information:
I use Synology Hybrid Raid and have 4 disks of 3TB. Effictive 8 TB Capacity and 6,8 TB available. But my total isn't shown.
By HDTotal i get 1011689 as value
But when i change the last digit to 37 i also receive 1011689

This also goes for HDUsed.

So i miss the total amount of my SHR

Re: HowTo: monitor Synology NAS

When I run the script I mostly get the message Timeout : no response
When pinging the ip-adres I get an answer within about .420 ms

Besides that I get an error message :
line 44: ( - ) * / 1024 / 1024 / 1024: syntax error: operand expected (error token is ") * / 1024 / 1024 / 1024")
But that can be caused by the time outs ?

The script in line 43 and 44 is :

Code: Select all

 HDUsed=`snmpget -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.2.1.25.2.3.1.6.41`  # Change OID to .38 on DSM 5.1 or .41 on DSM 6.0+
        HDFree=$((($HDTotal - $HDUsed) * $HDUnit / 1024 / 1024 / 1024))
I can't see anything wrong, the only thing I changes is .36 to .41
I have a synology 213J running on DSM 6.0+

NB: When running a single command like :
HDUsed=`snmpget -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.2.1.25.2.3.1.6.41`
I sometimes get a result but not often (time out)

I also have problems with this script with my DS416Play with latest firmware. The script partially works, I can get the HDD temp values, but no space used and cpu info. I've tried with .38 and .41 - it's just not working :(

I had the same isue but when I use .54 it works again om my DS 415+ with the last DSM 6.1.15047
Hope it helps
