Logstash plugin not recognized


#1

Hi,
I have installed the beta version of a plugin logstash-input-snmp, when I try to run the config file, I get this below error message:

Config File:

input {
  snmp {
    get => ["1.3.6.1.2.1.1.1.0", "1.3.6.1.2.1.1.3.0", "1.3.6.1.2.1.1.5.0"]
    hosts => [{host => "udp:**.**.**.**/161" community => "public",}]
  }
 }

output {
  stdout {
    codec => rubydebug
  }
} 

@axrayn - any clue on this ?
Please let me know how do I resolve this issue.

Hi @paul1243,

How did you install the plugin? Just with the normal bin/logstash-plugin install --version 0.1.0.beta5 logstash-input-snmp ?

I just tested that this morning and the jar file is correctly installed:

user@host:/usr/share/logstash# find . -name snmp* | grep logstash-input-snmp-

./vendor/bundle/jruby/2.3.0/gems/logstash-input-snmp-0.1.0.beta5/vendor/jar-dependencies/org/snmp4j
