I have the same problem as Duduf. After an upgrade of my synology the temperuture is gone. the script is still working (updated every x minutes) but something happened with the upgrade what caused it to receive 0

The solution of Ray worked! Thnx Ray

Anyone else having this problem, I have found the "solution"
The script uses snmpget which runs fine manually, and used to run fine in the cron too. Some update (I guess Synology DSM) caused the cron to run the script correctly, but gave 0C numbers in return.

Changing the script replacing all snmpget to snmpwalk did the trick, both manually and in cron it works again.
I have to thank Martijn85 above, as he made me aware of this in his correction of the script, where I finally sportted the use of snmpwalk instead snmpget.

Cheers,

Ray

Hello Alwin,

Does this part solves the problem with the 1024 issue? Untill now i haven't got succes in displaying the free mem for example.

I have domoticz on my Synology 916+, can read the temperature but the other parts aren't working.

Hope it helps

Beneath code I grabbed from the Dutch Synology Forum becouse the memory usage was wrong displayed.

Code: Select all

	       # Free Memory Used in %
       tmpMemAvailable=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.2021.4.6.0`
	   MemAvailable=${tmpMemAvailable%% *}
       tmpMemtotal=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.2021.4.5.0`
	   Memtotal=${tmpMemtotal%% *}
       tmpMemShared=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.2021.4.13.0`
	   MemShared=${tmpMemShared%% *}
       tmpMemBuffer=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.2021.4.14.0`
	   MemBuffer=${tmpMemBuffer%% *}
       tmpMemCached=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.2021.4.15.0`
	   MemCached=${tmpMemCached%% *}
       MemFREE=$(($MemAvailable + $MemShared + $MemBuffer + $MemCached))
       MemUsepercent=$(((($Memtotal - $MemFREE) * 100) / $Memtotal)) 
	   #// For Available use MemUsepercent=$(((($MemFREE) * 100) / $Memtotal))	   
       # Send data
       curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_MEM_IDX&nvalue=0&svalue=$MemUsepercent"

Running XPenology on a HPN54L with DSM 5.2

I have installed pearl and panorama9 packages https://support.panorama9.com/hc/en-us/ ... MP-add-on-

Then I can retrieve directly the available space by the following:

snmpwalk -v2c -c SNMPCOMMUNITY -O qv NASIP 1.3.6.1.4.1.8072.1.3.2.3.1.2.2.112.57 | grep free | cut -d , -f 5 | cut -d : -f 2 | cut -c 2-

Result to be divided by 1048576 to see it in Go

Hi,

I've tried to monitor my 415play from Domoticz... 4 temperature sensors instead of 2.
In DSM6, i've changed OID to .41 and i've created the sensors but...

Image

taking code from wiki... https://www.domoticz.com/wiki/NAS_Monitoring

It's working for 4 temperature and OK/KO activity sensor :

Image

But error on the other sensors ... maybe i made a mistake on the code or on the sensor declaration ?
(i've tried custom sensor instead of the picture ... same issue).

Hi,

Thanks for your support.
Could you confirm the type of the output in Domoticz ?

When I use your code (i've removed the 4 last temperature sensors), only HDD temperature sensors will working... and i have this error :

Code: Select all

}
./nas.sh: ligne 86: (No Such Instance currently exists at this OID - No Such Instance currently exists at this OID) * No Such Instance currently exists at this OID / 1024 / 1024 / 1024 : « ) » manquante (le symbole erroné est "Such Instance currently exists at this OID - No Such Instance currently exists at this OID) * No Such Instance currently exists at this OID / 1024 / 1024 / 1024")
Line 86 = Free Space Volume in Go.
The code does not check CPU, RAM etc... ?

Re: HowTo: monitor Synology NAS

Post by rjblake »

Suggest running the following command from the command line on Synology:

snmpwalk -v 2c -c"your password" "your NAS IP" 1.3.6.1.2.1.25.2.3.1 (where items in " " need to be replaced with yours)

This will return the information needed to determine the correct OID to check disk space. Look for a entry like the following (assuming you want info for /volume1):

HOST-RESOURCES-MIB::hrStorageDescr.52 = STRING: /volume1

Where .52 is correct for my setup, it may/will be something else for yours (e.g. 31, 41, 51, etc.). In the script, edit the relevant lines with the correct OID, such as:

# Free space volume in Go
HDUnit=`snmpwalk -v 2c -c $PASSWORD -O qvU $NASIP 1.3.6.1.2.1.25.2.3.1.4.52`
HDTotal=`snmpwalk -v 2c -c $PASSWORD -O qvU $NASIP 1.3.6.1.2.1.25.2.3.1.5.52`
HDUsed=`snmpwalk -v 2c -c $PASSWORD -O qvU $NASIP 1.3.6.1.2.1.25.2.3.1.6.52`
HDFree=$((($HDTotal - $HDUsed) * $HDUnit / 1024 / 1024 / 1024))

Do the same type of check for CPU, RAM, etc.

My devices as attached.

thnx to your post rjblake i saw my OID was .51
After that it worked. the values are much the same

Free space in Go (synology says 6.7TB, script ,6.918TB)
Free used space in % give me the % which is used, so i changed my text.

CPU en Mem usage i dont use, i use the motherboard feature in domoticz.

For a member of the Dutch Synology forum who needs to monitor various Synologys I've made an extension of the current script that lets you enter a the name of the volume want to investigate:

Code: Select all

	# Free space volume in Gb

	# Extra variable stating the name of the volume you want to read the free space of
	searchVolume="volume1"

	# read the output of the complete hrStorageDescr
	tmpVolume=`snmpwalk -v 2c -c $PASSWORD  $NASIP .1.3.6.1.2.1.25.2.3.1.3`
	# adjust string separator to line-break
	IFS=$'\n'
	# array with all hrStorageDescr's
	storageArray=($tmpVolume) 
	for index in "${!storageArray[@]}"
	do
		# is the current hrStorageDescr equal to searchVolume 
		if [[ ${storageArray[index]} =~ .*$searchVolume.* ]]
		then
			# get the complete hrStorageDescr line sought
			foundVolume=${storageArray[index]}
			# adjust string separator to '.'
			IFS=$'.'
			# split into array (eg. element 0='HOST-RESOURCES-MIB::hrStorageDescr'; element 1 ='41 = STRING: /volume1')
			foundStorageArray=($foundVolume)
			# get first two numbers as the right hrStorageDescr element number
			hrStorageDescr=${foundStorageArray[1]:0:2}
		fi
	done
	echo "hrStorageDescr of $searchVolume = $hrStorageDescr"
	# re-adjust string separator to line-break
	IFS=$'\n'
	tmpHDUnit=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.4.$hrStorageDescr`
	echo "HDUnit:" $tmpHDUnit
	HDUnit=${tmpHDUnit%% *}
	HDTotal=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.5.$hrStorageDescr`
	echo "HDTotal:" $HDTotal
	HDUsed=`snmpwalk -v 2c -c $PASSWORD -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.6.$hrStorageDescr`
	echo "HDUsed:" $HDUsed
	HDFree=$((($HDTotal - $HDUsed) * $HDUnit / 1024 / 1024 / 1024))
	echo $HDFree

	# Send data
	echo "Sending data to device#:" $NAS_HD_SPACE_IDX
	curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_HD_SPACE_IDX&nvalue=0&svalue=$HDFree"
	echo "Data sent"

	# Free space volume in percent
	HDTotal=`snmpwalk -c $PASSWORD -v2c -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.5.$hrStorageDescr`
	echo "HDTotal:" $HDTotal
	HDUsed=`snmpwalk -c $PASSWORD -v2c -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.6.$hrStorageDescr`
	echo "HDUsed:" $HDUsed
	HDUsedPerc=$((($HDUsed * 100) / $HDTotal))
	echo "HDUsedPerc:" $HDUsedPerc

	# Send data
	echo "Sending data to device#:" $NAS_HD_SPACE_PERC_IDX
	curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_HD_SPACE_PERC_IDX&nvalue=0&svalue=$HDUsedPerc"
	echo "Data sent"
Works like a charm on both my Syno's.
Hope you guys find it usefull :P

Sorry for the very late answer but I don't get a message saying someone reply at my question. I decide today to try again to get it works.
SNMP is on on the NAS.
Any idea what the problem can be?

Why not keep it simple and just run a script on the nas to check disk space and sent warning when over a treshold?

Would be nice to monitor my two D110j's (if I ever can find those Power supplies).

I'm not sure if I'm able to help you find them :mrgreen:
But if you need assistance with the script please tell me.

ThaBoo wrote:@rvmourik Thanx for the script!

Got it all set up within 30 minutes.
Configuration: DS1010+ DSM 4.3-3810, Raspberry PI Domoticz V1.1492 ( and a Plugwise Circle for the power consumption)

Synology Domotics.gif
Does this script (with Plugwise Circle) also work on Domoticz on Synology? and how do i name this script?

[/quote]Does this script (with Plugwise Circle) also work on Domoticz on Synology? and how do i name this script?[/quote]
Finaly, thanks to everybody in this thread, I think I got it to work with Domoticz installed on a Synology NAS (DSM 5.2) to monitor another NAS (DSM 6.0 with two HDD in 1 JBOD volume). But without Plugwise Circle.

Just have to put it in cron to get complete.

Here is the code :
