Linux access to the sensor readings

Dear all
I am trying to access to the sensors' reading through snmp from a linux machine.
I enabled on the sensorcheck interface the snmp protocol and I managed to connect to it from my linux server:

[root@fotcluster2 ~]# snmpwalk -v2c -cpublic 10.208.130.18
SNMPv2-MIB::sysDescr.0 = STRING: Temperature & Sensor Gateway
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.17095
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (24358512) 2 days, 19:39:45.12
SNMPv2-MIB::sysContact.0 = STRING: http://www.serverscheck.com
SNMPv2-MIB::sysName.0 = STRING: SensorGateway
SNMPv2-MIB::sysLocation.0 = STRING: Data Center

However I am unable to find the reading of the sensors.
I've tried also to use the mib for the specific sensor but the results is rather puzzling to me:

[root@fotcluster2 ~]# snmpwalk -MALL -v2c -cpublic 10.208.130.18

iso.3.6.1.2.1.1.5.0 = STRING: "SensorGateway"

Now the question is: can the reading be accessed in Linux without having to setup a trap (and hence a server who receives the trap)?

  • Hi antonio,

    have you tried doing another walk and have it start with ".1.3.6" I can give you specific OID's if you need it or you can do an SNMP walk using our software on a windows platform and then list the OID's you want to access through your linux system and create scripts of SNMP get to access the specific values you need.
