Logstash input jdbc :unknown error:


(Olatunde Tokun) #1

Hey,

I use multi pipeline to ingest logs from a database using jdbc driver. It works great, but every once (once in 2 hours) in a while I see errors from the jdbc input plugin.

There are no missing events because it uses a timebased sql_last_value, but im curious to know why there are these errors and how it can be resolved.

[2018-06-05T12:34:02,702][ERROR][logstash.inputs.jdbc     ] Java::JavaSql::SQLException: unknown error: SELECT client_application_id, client_application_name, FROM_UNIXTIME(connection_sec), HEX(dst_ipaddr) as dst, dst_port, event_id, FROM_UNIXTIME(event_time_sec) as rt, impact, interface_egress_name, interface_ingress_name, protocol_name, protocol_num, priority, rule_classification, rule_classification_id, rule_message as name, rule_signature_id, rule_generator_id, security_zone_egress_name, security_zone_ingress_name, sensor_name, sensor_address, HEX(src_ipaddr) as src, src_port, src_user_name, vlan_id FROM table WHERE FROM_UNIXTIME(connection_sec)>'2018-06-05 16:33:01.814906'

The input config file is below:

add_field => { "source" => "tablename" }
tracking_column_type => "timestamp"

}
}

Thanks in advance.

Below is running LS in debug mode. Though not sure how Im supposed to fix this. Is this happening because LS is trying to count the amount of rows to be added? Any ideas or pointers would be appreciated.
