Greetings all ,

We have Juniper SRX on our environment and when activate netflow V5/V9 or Jflow,there is no traffic been captured in PRTG...

below is the configuration at SRX Juniper ;

SRX> configure 
Entering configuration mode

[edit]
SRX# replace pattern XX.XX.97.190 with XX.XX.167.87 

[edit]
SRX# show | compare 
[edit snmp client-list APP-SSC-Monitoring]
     XX.XX.104.202/32 { ... }
+    XX.XX.167.87/32;
     XX.XX.168.21/32 { ... }
[edit snmp client-list APP-SSC-Monitoring]
-    XX.XX.97.190/32;
[edit snmp trap-group router-traps targets]
     XXX.XX.64.153 { ... }
+    XX.XX.167.87;
     XXX.XX.77.69 { ... }
[edit snmp trap-group router-traps targets]
-    XX.XX.97.190;
[edit forwarding-options sampling family inet output]
+       flow-server XX.XX.167.87 {
+           port 2055;
+           source-address XX.XX.247.23;
+           version 5;
+       }
-       flow-server XX.XX.167.87  {
-           port 2055;
-           source-address XX.XX.247.23;
-           version 5;
-       }

Even after this config been pushed to Juniper srx,from prtg level, we still cant able to detect the flow..

Please advise....Thanks.

Hi Mr. K,
I would recommend to take a look at our Netflow Tester. With this tool you can debug your configuration and check which data could be received by PRTG. Please note you need to pause the sensor while you are using the tool.

Kind regards
