HowTo: monitor Synology NAS

[MAidEN]

Yes we can add this tip on Wiki. How do that?

@zaadstra : I think if you monitor your synology (cpu, mem, temp, ping) from your domoticz, synology can't be sleep mode...

Anybody has a idea for my problem with HDD space monitor?

I have the solution for the Disk monitoring of my NAS with the screenshot above. The OID of Volume1 is 38.

The code for Free Space in GB

Code: Select all

 # Free space volume1 (GB)
                                HDUnit=`snmpget -c $PASSWORD -v2c -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.4.38`

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

                                # Send data
                                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"

The code for Free Space in Percent

Code: Select all

 # Free space volume1 (Percentage)
                                HDTotal=`snmpget -c $PASSWORD -v2c -O qv $NASIP .1.3.6.1.2.1.25.2.3.1.5.38`

The above seems to work indeed.

Thanks is ok now, but I don't understand why I have a value "7" on title :



The good value is 5901 Go.

The percent monitor is ok.

It's good I had update the wiki page with this news :

Cpu monitor
Memory monitor
Disk usage in %
And I add a coment with new OID for disk usage to DSM 5.1 (.38)

Hello, i'm new with this, using domoticz for a few days know.
So I have questing, how do i make a virtual Switch en the virtual temperature sensors?
I have the script running on the Pi. But when I test it i get this.

[roblom]

So I have questing, how do i make a virtual Switch en the virtual temperature sensors?

• Go to "Hardware"
• Choose for type "Dummy (does nothing, use for virtual switches only"
• Give it a name, like "NAS"
• Click on "add"
• Now in the device list there is a new hardware created. In this line of "NAS" is a button with "create virtual sensors"
• When you click on this, choose what kind of device you need. For the NAS Script you need a counter for example.
• Click "ok"
• Now in the devices tab there is a new device created. Click on the green arrow behind it and give it a name.
• Now there is a device created on the tab "Several" (or other if you choose a different type of device).

Look in the device tab in the column IDX for the IDX number of the device, then change this in the NAS script. Create more devices if you need more.

[sincze]

Excellent .

Thanks for the quick reply. I will give it a try

[SwordFish]

I've managed to get the virtual switches but when i test the script i'll still get this?

[roblom]

Did you make the script executable:

Code: Select all

sudo chmod +x nas.sh

Is this a windows machine?

[SwordFish]

I've managed to get it work. But there are a few things that i don't get to work.
- Memory use is allways 1%?
- Its seems that the crontab is not working, because it doesn't update?
But when I run nas.sh in the terminal its working. ( I've another crontab running what is working)
- On dashboard the free HD space doesn't show the right free space.

When you paste some code here it's better to use the code tags.

I think the problem is in your cronjob, the "(= every 5 minutes)" is not allowed because it don't understands what it means so it gives an error.

[SwordFish]

Thanks, will remove that.
Sorry for not using the code tags, didn't know .

In the script something is wrong. To calculate the free memory percent, the MemAvailable will be divided by 1024. For a synology with 1024MB RAM, this is right. But not for a synology with 512MB RAM. Maybe the script can be updated!

The old script contains:

Code: Select all

   # 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_USER:$DOMO_PASS@$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_MEM_IDX&nvalue=0&svalue=$MemUsepercent"

Maybe this can be the solution:

Code: Select all

	# Free Memory Available in %
	MemAvailable=`snmpget -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.2021.4.6.0`
	MemTotal=`snmpget -v 2c -c $PASSWORD -O qv $NASIP 1.3.6.1.4.1.2021.4.5.0`
	MemUsepercent=$((($MemAvailable * 100) / MemTotal))
	# Send data
	curl -s -i -H "Accept: application/json" "http://$DOMO_IP:$DOMO_PORT/json.htm?type=command&param=udevice&idx=$NAS_MEM_IDX&nvalue=0&svalue=$MemUsepercent"

When I look in my DSM of my Synology the percent will be 48%. The script shows 3%. I don't know why both values are different. Hopefully somebody can explain this?

i Jan,

Is right, we have a problem with this formul.

On my Synology i have that :



On Domoticz :



I don't understand how synology obtain 33% memory use...is egal to 337,92 Mo.

On my screen memory free (libre) = 106 Mb (10,5%) !

You have a same problem ?

[globalassist]

Is there a way to monitor this in a windows-installation of Domoticz?

[MAidEN]

The script is for linux installation of domoticz only : http://www.domoticz.com/wiki/NAS_Monitoring
