Trying to create sensor for asa 5585 and i got this error: 

Sensor does not get response from device. SNMP credentials are wrong or device does not support the required uptime OID (1.3.6.1.2.1.1.3.0) for traffic sensors. This OID is mandatory by the SNMP RFC. Check SNMP access rights or contact device vendor. (code: PE244)

What is the SNMP configuration of the device (SNMP version, community string, port)? Does it match the settings in PRTG?

Copy the following content into a texteditor and save it as traffic_walk.txt for example: 
--
Interfaces Table Query
--
System Uptime Check
walk=1.3.6.1.2.1.1.3
walk=1.3.6.1.2.1.25.1.1
--
System Description
walk=1.3.6.1.2.1.1.1

walk=1.3.6.1.2.1.31.1.1

Use our SNMP Tester, configure it to point at your device with the required SNMP settings, use option Scan Script and load traffic_walk.txt there.


It looks like the device does not respond to SNMP requests at all. This can have several reasons:

  • The device does not support SNMP v2c, so try SNMP v1 instead. Please also check the device's SNMP configuration.
  • Device cannot be reached. Are you using its hostname or IP in SNMP Tester? Use IP in case you used the hostname to make sure the tester points to the correct device and rule out name resolving issues.
