Nagios Support Forum

I have been trying to use every configuration wizard available to get interface discovery of my Juniper SRX firewalls. I have followed all of Junipers directions for enabling the SNMP and my Cacti can pull everything from the firewalls but not Nagios XI. Can someone please tell me what i am missing?

From the Nagios XI CLI, what is the result of running an snmpwalk against one of these firewalls?

snmpwalk -v2c -c <community> <IP ADDRESS OF HOST>
or snmpget:
snmpget -v2c -c <community> <IP ADDRESS OF HOST>

I was able to get the the interfaces discovered by using the Network Switch / Router configuration wizard. but it is unable to create the graphs. My firewall is configured as such

auth-trap-disable;
view jweb-view-all {
oid .1 include;
}
community CSA-Auburn {
view jweb-view-all;
authorization read-write;
}
trap-group CSA-Auburn {
version v2;
categories {
chassis;
link;
routing;
startup;
rmon-alarm;
configuration;
}
targets {
10.18.22.166; - "Cacti"
10.18.22.192; - "Nagios XI"
}

set policy-options prefix-list snmp-addresses 10.18.22.192 (This corrected the issue)

The service detail screen starts out like the image file Adding Firewall

But then it ends up like the image file Firewall Results

Now the worst part is if I add it the same way using its IP address 10.68.156.9 like i did originally, but do not change the host name it works perfectly as shown in the No host name change attachment

From the CLI of Nagios, can you resolve the hostname you were attempting to use? Are there any special characters in it?
