Nagios Network Analyzer monitor Dell Force10 switch in sFlow

Post by rlneo »

Hello All,

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

Code: Select all

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.

Hello, @rlneo. I don't know the specific instructions on how to configure Sflow on your switch(maybe other users here will help with that). But a good way to get those instructions is to contact the manufacturer directly.
What I'd would suggest is to check whether port 6343 is restricted by a firewall on the Nagios NNA server. You could also run iptables -nL to make sure that NNA is actually listening on the port 6343. I'd also try to telnet the switch from the NNA server.

It looks like you were following this?
http://www.dell.com/support/article/us/ ... es?lang=en

I don't know exactly, but since you configured sFlow globally.

Have you tried setting sFlow at the interface level?
