SNMP Polling Very slow boot up time

Elastic Stack Logstash

Thanks for your answer @Badger. It took some time to adjust the configuration but now I'm getting an expected error when I have more then 1 host setup.

This is my configuration file with some strings/hosts changed.

input {


    snmp {
        interval => 30

        tables => [

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListConfiguredName.34" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.3.34" ] } ,

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListConfiguredName.35" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.3.35" ] } ,

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListConfiguredName.36" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.3.36" ] } ,

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListSystemPointer.35" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.7.35" ] } ,

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListSystemPointer.36" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.7.36" ] }

        ]

        # List of hosts to poll
        hosts => [ 
              {host => "udp:Hostname1/161" community => "public" version => "2c"  retries => 2  timeout => 1000 }, 
              {host => "udp:hostname2/161" community => "public" version => "2c"  retries => 2  timeout => 1000 } 
        ]

        add_field => {
            "[@metadata][projectId]" => 1
            "[@metadata][collectionId]" => 1
        }
    }

}

On the other hand this is a working configuration:

input {


    snmp {
        interval => 600

        tables => [

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListConfiguredName.34" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.3.34" ] } ,

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListConfiguredName.35" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.3.35" ] } ,

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListConfiguredName.36" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.3.36" ] } ,

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListSystemPointer.35" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.7.35" ] } ,

            { "name" => "oid.ALPHA-RESOURCE-MIB::componentListSystemPointer.36" "columns" => [ "1.3.6.1.4.1.7309.5.2.1.2.1.7.36" ] }

        ]

        hosts => [{host => "udp:HOSTNAME1/161" community => "public" version => "2c"  retries => 2  timeout => 1000 } ]

        add_field => {
            "[@metadata][projectId]" => 1
            "[@metadata][collectionId]" => 1
        }
    }


}

I tried making the configuration all one line for hosts it didn't seem to make any difference. Any thoughts?

UPDATE:: I misspoke, it seems to be an issue with some of the MIBs i was using, not the config. The Alpha PDU oids are not working for some reason.
