nagios network analyzer and dell Force10 switch monitoring i

[SnowranCruzick]

I setup nagios network analyzer and trying to monitor a Dell Force10 switch, i enabled sflow in Force10 side as follows:

DELL-S4048-K13#show sflow
sFlow services are enabled
Egress Management Interface sFlow services are disabled
Global default sampling rate: 256
Global default counter polling interval: 15
Global default extended maximum header size: 256 bytes
Global extended information enabled: switch
2 collectors configured
Collector IP addr: 10.62.73.158, Agent IP addr: 10.62.91.245, UDP port: 6343
VRF: Default
Collector IP addr: 10.32.98.202, Agent IP addr: 10.62.91.245, UDP port: 6343
VRF: Default
0 UDP packets exported
357 UDP packets dropped
0 sFlow samples collected

stack-unit 1 Port set 0
Te 1/1: configured rate 256, actual rate 256
Te 1/2: configured rate 256, actual rate 256
In nagios NA server i'm trying to add a source, in type of sFlow, with IP and port of Dell Force10 enter.

Unluckly no data is collected.

Anyone has success experience in monitor a Dell Force10 switch in Nagios?

Thanks.

Hi @SnowranCruzick, thanks for reaching out.

What have you tried so far from the debugging/troubleshooting side of things? If you haven't yet, I would recommend running tcpdump on the NNA server to see if there's any incoming data at all. If there isn't, I would check firewall settings and/or see if there's anything intercepting/dropping the data between your switch and the NNA server.

Please let me know what you find out, and feel free to ask if you have any other questions or concerns
