Timestamp at Input section

Elastic Stack Logstash

Hello Guys,

I am utilizing the @timestamp field in a DB2 Query. I am using the JDBC plugin, where in I am relying on the @timestamp field for my date parameters.

Now, thing is I cannot use the @timestamp because it has the T, Z and : in it's value(2016-09-01T19:21:08.702Z). Is there a way to parse it at the input section so I can omit the T, Z and colons?

Can you share your config? You can generally format dates using sprintf format like %{yyyy-mm-dd}

Hi Andrew,

I cant share my config File.
I tried to google that sprintf you indicated. As I saw in the documentation, this cannot be done in the Input section.

Field references, sprintf format and conditionals, described below,
will not work in an input block.

Also, as I see in the examples it is only used in the outputs. Is there no other way? :smiley:

How are you pulling the timestamp from @timestamp in an input? There's no event to pull it from.

This is far too confusing to understand without a config file. Can you just share your JDBC input config?

Hello!

Yep, that I can share.

input {

if [@timestamp] < "01:00:00.000Z" and [@timestamp] > "02:00:00.000Z" {
    stdin {
        add_field => { "dummy" => "'2016-09-01-00.00.00' AND '2016-09-01-02.59.00'"}
    }
}

jdbc {
    jdbc_driver_library => "jarFiles/db2jcc-10.1.0.jar"
    jdbc_driver_class => "com.ibm.db2.jcc.DB2Driver"
    jdbc_connection_string => "jdbc:db2://localhost:9200/dummyDB"
    schedule => "59 * * * *"
    statement => "select content from rawbcmsg where LASTUPDATE BETWEEN %{dummy}"
    type => "CDT1"
}

}

Thanks,

I think the confusion here is that the stdin input does not at all have any way to conect to the jdbc input. You would need a JDBC filter which we do not unfortunately have. It'd be awesome if someone made one however!

To expand on that, inputs can only generate events, they cannot react to other inputs.

I guess that answers my question Andrew,Thanks.
