Hi all,
I'm trying to get the snmp input plugin work using SNMPv3 and, if the plugin doesn't show any error on start up, It doesn't retreive any information either.
I'm using logstash 6.5 with the following configuration:
snmp {
walk =\> ["1.3.6.1.4.1.2021.9.1"]
auth\_pass =\> "the\_good\_pass"
auth\_protocol =\> "sha"
priv\_pass =\> "the\_good\_passwd"
priv\_protocol =\> "aes"
security\_name =\> "the\_good\_sec\_name"
security\_level =\> "authPriv"
hosts =\> [{host =\> "udp:my\_ip\_address/161" community =\> "my\_community" version =\> "3"}]
type =\> "snmp"
id =\> "snmp"
}
tried to put logstash on debug in order to see what's going on but the only information regarding this plugin is :
[2018-11-30T12:16:19,409][INFO][logstash.inputs.snmp] using plugin provided MIB path /usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-snmp-1.0.0/lib/mibs/logstash

when using snmpwalk :

Could you help me debug my configuration ?

Also I notice in the input your specifying a security\_name parameter, but in your snmpwalk command it has a different value?

Nothing : no errors, no logs, no data.
When looking at the pipeline statistics, I can see that there is no data in.
So for me, it just don’t start correctly.
I’m on RHEL7.1 using oracle java 1.8.

No, I’ved double check all the parameters.

Are you running logstash as a service?

If you do "journalctl --unit=logstash -f" do you see anything being output to stdout?
