SNMP is a powerful protocol that enables real-time monitoring of server hardware health, including temperature sensors, fan speeds, voltage levels, and power supply status.
By continuously tracking these metrics, SNMP helps you detect potential issues early, enabling proactive maintenance before they become critical hardware failures.
It also integrates seamlessly with popular monitoring platforms such as Zabbix, Nagios, and Prometheus, making it easy to centralize and automate infrastructure monitoring.
Download and install Supermicro MIBs
Step 1. Connect to monitoring server via SSH as root
ssh root@<your_ip_address_or_hostname>
Step 2. Become Super User
sudo su
Step 3. Download the MIB files from the official Supermicro website on monitoring server
Step 4. Create a folder to extract the contents of the downloaded ZIP, if it doesn't already exist (replace <path_folder_to_extract> with the correct information)
mkdir <path_folder_to_extract>EXAMPLE
mkdir /usr/share/snmp/mibs/supermicro
Step 5. Extract the files downloaded at Step 3 into the folder created at Step 4 (replace <downloaded_file_name> and <path_folder_to_extract> with the correct information)
unzip <downloaded_file_name>.zip -d <path_folder_to_extract>
Step 6. Update SNMP configuration (replace <path_folder_to_extract> with the correct information)
echo "mibs +ALL" >> ~/.snmp/snmp.conf export MIBDIRS=<path_folder_to_extract>:$MIBDIRSEXAMPLE
echo "mibs +ALL" >> ~/.snmp/snmp.conf export MIBDIRS=/usr/share/snmp/mibs/supermicro:$MIBDIRS
Test SNMP Communication
SNMPv3 (replace <user>, <authPass>, <privPass>, <IPMI_IP_ADDRESS> with the correct information)
snmpwalk -v3 -l authPriv -u <user> -A <authPass> -a SHA -X <privPass> -x AES <IPMI_IP_ADDRESS> sysDescr.0

Sensor data retrieval via SNMP (use OIDs or MIB labels)
EXAMPLE (FAN1 RPM)
snmpwalk -v2c -c public <IPMI_IP_ADDRESS> 1.3.6.1.4.1.21317.1.3.1.2.32
Get the sensor name (replace <IPMI_IP_ADDRESS> with the correct information)
snmpwalk -v2c -c public <IPMI_IP_ADDRESS> <SNMP OID>EXAMPLE
snmpwalk -v2c -c public <IPMI_IP_ADDRESS> 1.3.6.1.4.1.21317.1.3.1.13.32
After MIBs are loaded, SNMP tools can interpret and display named labels (replace <IPMI_IP_ADDRESS> and <SNMP_OID> with the correct information)
snmpwalk -v2c -c public <IPMI_IP_ADDRESS> <SNMP_OID>EXAMPLE
snmpwalk -v2c -c public <IPMI_IP_ADDRESS> sensorReading.32
