Encore merci papoo, j'ai mis à jour la modif avec les 4 températures des HDD si des personnes le veulent le voici.
Tu va le mettre sur le GitHub ? Je suis en train de faire un article pour un blog info et j'envoi l'article vers ton Github pour récupérer le script. Merci

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
