Activer SNMP sur votre Synology NAS
Le service SNMP (dans Panneau de configuration > Terminal & SNMP > SNMP) permet aux utilisateurs de surveiller le Synology NAS avec le logiciel de gestion du réseau. Actuellement, les protocoles SNMPv1, SNMPv2c et SNMPv3 sont pris en charge.
Activation du service SNMP
Cochez Activer le service SNMP et suivez les étapes ci-dessous.
Pour activer le service SNMPv1, SNMPv2c :
Cochez Service SNMPv1, SNMPv2c.
Saisissez un nom de Communauté.
Cliquez sur Appliquer.
<strong>Installation de SNMP sur Raspberry Pi (ou système linux)</strong>
Connectez-vous à vous à la console de votre Raspberry Pi:
Code : Tout sélectionner
sudo apt-get install snmpd
sudo apt-get install snmpCode : Tout sélectionner
sudo rebootCode : Tout sélectionner
snmpget -v 2c -c PASSWORD -O qv NASIPADDRESS 1.3.6.1.4.1.6574.1.5.1.0
Remplacer NASIPADDRESS par l'adresse ip de votre NAS
Vous devriez obtenir quelque chose comme ceci :
"DS218+" qui correspond au modèle de votre synology
testez les 3 requetes suivantes
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
puis modifiez les variables OID_HDUnit, OID_HDTotal, OID_HDUsed (.38 sur DSM 5.1, .41 sur DSM 6.0+ ou .31 sur mon nouveau synology DS218+)
Ensuite créez :
1 device Interrupteur
X device température
3 devices pourcentage
1 device compteur
il ne vous reste plus qu'a créer un fichier Synology.lua que vous placerez dans /home/pi/domoticz/scripts/dzVents/scripts/Synology.lua
dont vous personnaliserez le code suivant
le script complet

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
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
