Many sensors return 0 value on my Juniper SRX




I'm trying to install sensors on a Juniper SRX 3400 cluster.

I want to monitor "health system" for each device.

I found this link, and followed the procedure.

Now, i have many sensors for this device.
But the problem is that many of them return "0" value. (even if global status is "OK" with green color) Like all FAN on both cluster node. And some other.

I ran the following script on SNMP tester :

MIB-2 System


And i got this result :

Paessler SNMP Tester 5.2.3 Computername: BDITA0PRT01 Interface: 10.XX.XX.XX
19/11/2018 11:10:42 (4 ms) : Device: 10.XX.XX.XX

19/11/2018 11:10:48 (6052 ms) : Error: -2003

What could i do ?

PS : some other sensors are returning values like Sensor
Junos Health: node0 FPC: SRX3k SPC @ 2/*/*

Hello there,

The return code "-2003" means that the target device does not respond to the requested OIDs. Since you get results in PRTG it's strange that the tester displays this message.

Please check the following:

  • Is the SNMP tester running on the corresponding (Remote) Probe?
  • Does the tester use the correct SNMP credentials?
    Please let me know if you could get correct results in the tester.

Kind regards,
Birk Guttmann, Tech Support Team
