For this script to work you need to enable SNMP on your synology NAS and install SNMP on your Raspberry Pi

Enable SNMP on your synology NAS

Go toMain Menu>Control Panel >SNMP to enable SNMP service, which allows users to monitor
Synology DiskStation network flow with the network management software.

You can use V1/V2
And set a password (Community)

Install SNMP on Raspberry Pi
Log in to you Raspberry Pi and issue:

sudo apt-get install snmpd
sudo apt-get install snmp

Reboot your Pi:
sudo reboot

Check if SNMP is up and running, issue:
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.4.1.6574.1.5.1.0

Replace PASSWORD with the Community name you entered while setting up your NAS
Replace NASIPADDRESS with the ip address of your NAS
You should get something like this:
"DS218+" which corresponds to your Synology Model

test
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.31
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.38
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.41
then modify OID_HDUnit, OID_HDTotal, OID_HDUsed variables (.38 on DSM 5.1, .41 on DSM 6.0+ or .31 on my new DS218)

if you have à DS2XX model, uncomment -- local OID_HDtemp2='1.3.6.1.4.1.6574.2.1.1.6.1' to show the hdd2 temperature

Then create:
1 device Switch
x temperature device
3 percent devices
1 meter device
all you have to do is create a Synology.lua file that you will put in /home/pi/domoticz/scripts/dzVents/scripts/Synology.lua
you will customize the following code

You should get something like this:
"DS218+" which corresponds to your Synology Model

how to choose disk capacity to monitor?

snmpwalk -v 2c -c PASSWORD NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.3
results of my DS218 :

HOST-RESOURCES-MIB::hrStorageDescr.1 = STRING: Physical memory
HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: Virtual memory
HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: Memory buffers
HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: Cached memory
HOST-RESOURCES-MIB::hrStorageDescr.8 = STRING: Shared memory
HOST-RESOURCES-MIB::hrStorageDescr.10 = STRING: Swap space
HOST-RESOURCES-MIB::hrStorageDescr.31 = STRING: /
HOST-RESOURCES-MIB::hrStorageDescr.36 = STRING: /tmp
HOST-RESOURCES-MIB::hrStorageDescr.37 = STRING: /run
HOST-RESOURCES-MIB::hrStorageDescr.38 = STRING: /dev/shm
HOST-RESOURCES-MIB::hrStorageDescr.39 = STRING: /sys/fs/cgroup
HOST-RESOURCES-MIB::hrStorageDescr.40 = STRING: /run/cgmanager/fs
HOST-RESOURCES-MIB::hrStorageDescr.51 = STRING: /volume1
HOST-RESOURCES-MIB::hrStorageDescr.54 = STRING: /volume1/@docker/btrfs


then modify     OID_HDUnit, OID_HDTotal, OID_HDUsed variables with your last number choice (.38 on DSM 5.1, .41 on DSM 6.0+ or .51 on my new DS218)

if you have à DS2XX model, uncomment     -- local OID_HDtemp2='1.3.6.1.4.1.6574.2.1.1.6.1'  to show the hdd2 temperature
Then create:
1 device Switch
1 temperature device
3 percent devices
x meter device

Tnx. Nice to see somebody managed to move the script towards dzvents. Maybe add it to the Domoticz general wiki as well under Monitor NAS ??

Thanks for your script! It's easy to install but i get a error in the domoticz log:

Code: Select all

Now it only updates NAS_HD1_TEMP
I'm using domoticz beta version: 4.9980 and Synology nas DS1513+ DSM 6.2-23739 Update 2

Re: Monitor Synology NAS with SNMP

comment line 86 level = domoticz.LOG_ERROR, -- Only one level can be active; comment others
uncomment line 87 -- level = domoticz.LOG_DEBUG,

what the result on your log?

OID HD Unit Change OID to .38 on DSM 5.1 or .41 on DSM 6.0+
OID Total space volume in Go Change OID to .38 on DSM 5.1 or .41 on DSM 6.0+
OID Space used volume in Go Change OID to .38 on DSM 5.1 or .41 on DSM 6.0+
if you have a new synology nas try .31
if you want to try in command line before install this script

Code: Select all

snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.31
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.38
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.41

if you want to try in command line before install this script

Code: Select all

snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.31
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.38
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.2.1.25.2.3.1.5.41

Hello

Just one remark. On my DS216Play I am using .42 with the last DSM.

I'm getting these errors:

2019-03-26 16:10:00.204 Status: dzVents: Error (2.4.15): Synology Monitor v1.04 : An error occured when calling event handler SynologyNAS
2019-03-26 16:10:00.204 Status: dzVents: Error (2.4.15): Synology Monitor v1.04 : ...cz/var/scripts/dzVents/generated_scripts/SynologyNAS.lua:75: attempt to perform arithmetic on field '?' (a nil value)

Can someone point me in the right direction?

With DSM7 my 2 disks are located at .1.3.6.1.2.1.25.2.3.1.5.47 and .1.3.6.1.2.1.25.2.3.1.5.48

This instead of .38 or .41

For those who connect a APC UPS to the Synology you could use:

Code: Select all

    local OID_UPS_STATUS = '1.3.6.1.4.1.6574.4.2.1.0'       -- OID Ups status
    local OID_UPS_RUNTIME = '1.3.6.1.4.1.6574.4.3.6.1.0'    -- OID Ups runtime
    local OID_UPS_CHARGE = '1.3.6.1.4.1.6574.4.3.1.1.0'     -- OID Ups status
    local UPS_Status = ""
...    
                ..OID_UPS_STATUS..' '..OID_UPS_RUNTIME..' '..OID_UPS_CHARGE..' '
...
        if results[17] then
            if results[17] == '"OL"' then UPS_Status = 'ONLINE'
            elseif results[17] == '"OB"' then UPS_Status = 'ON BATTERY'
            elseif results[17] == '"LB"' then UPS_Status = 'LOW BATTERY'
            elseif results[17] == '"HB"' then UPS_Status = 'HIGH BATTERY'
            elseif results[17] == '"RB"' then UPS_Status = 'REPLACE BATTERY'
            elseif results[17] == '"OL CHRG"' then UPS_Status = 'CHARGING'
            elseif results[17] == '"OB DISCHRG"' then UPS_Status = 'DISCHARGING'
            elseif results[17] == '"BYPASS"' then UPS_Status = 'BYPASS'
            elseif results[17] == '"CAL"' then UPS_Status = 'CALIBRATION'
            elseif results[17] == '"OFF"' then UPS_Status = 'OFF'
            elseif results[17] == '"OVER"' then UPS_Status = 'OVERLOAD'
            elseif results[17] == '"TRIM"' then UPS_Status = 'SMART TRIM'
            elseif results[17] == '"BOOST"' then UPS_Status = 'BOOST'
            elseif results[17] == '"FSD"' then UPS_Status = 'FORCE SHUTDOWN'
            else UPS_Status = 'UNKNOWN'
            end
            dz.log("NAS UPS status : "..tostring(UPS_Status),dz.LOG_DEBUG)
            if NAS_UPS_STATUS ~= nil then dz.devices(NAS_UPS_STATUS).updateText(UPS_Status) end
        end

        if results[18] then
            dz.log("NAS UPS runtime : "..tostring(dz.utils.round(results[18]/60,0)),dz.LOG_DEBUG)
            if NAS_UPS_RUNTIME ~= nil then dz.devices(NAS_UPS_RUNTIME).update(0,dz.utils.round(results[18]/60,0)) end
        end

        if results[19] then
            dz.log("NAS UPS charge : "..tostring(dz.utils.round(results[19],0)),dz.LOG_DEBUG)
            if NAS_UPS_CHARGE ~= nil then dz.devices(NAS_UPS_CHARGE).update(0,dz.utils.round(results[19],0)) end
        end
Change the index (17,18,19) to the real index.
Status is a Text device, Runtime a custom sensor with axis -> mins and Charge is a percentage device.

The OID_CpuUser and OID_CpuSystem are momentary values, and vary a lot.
Beter use the one (or more) of the load values:

Code: Select all

    local OID_Cpu_1min = '1.3.6.1.4.1.2021.10.1.3.1'
    local OID_Cpu_5min = '1.3.6.1.4.1.2021.10.1.3.2' 
    local OID_Cpu_15min = '1.3.6.1.4.1.2021.10.1.3.3'

On DS920+ with DSM7 it is .57

On DSM 7.0 you can walk 1.3.6.1.2.1.25.2.3.1 and starting 1.3.6.1.2.1.25.2.3.1.31 you will see textual description of the different mounts.
This is part of mine:

Code: Select all

01/09/2021 15:30:20 (178 ms) : 1.3.6.1.2.1.25.2.3.1.3.31 = "/" [ASN_OCTET_STR]
01/09/2021 15:30:20 (197 ms) : 1.3.6.1.2.1.25.2.3.1.3.56 = "/volume1" [ASN_OCTET_STR]

Here you can find that my volume1 is on 1.3.6.1.2.1.25.2.3.1.3.56 Yours might differ on the last digits.
The corresponding data for calculating free space is on:

Code: Select all

1.3.6.1.2.1.25.2.3.1.4.56  -> Unit
1.3.6.1.2.1.25.2.3.1.5.56  -> Total space
1.3.6.1.2.1.25.2.3.1.6.56  -> Used space
