Hi, I have a log that shows the interface usage (eth0/eth1) at a particular time , it logs in bytes and while logstash is able to parse it , elasticsearch seems to be rejecting it . Any workaround for this ? , in the component template , i gave the mapping as. "bytes\_written" -\> "numeric/byte" here's a sample log ```auto 1 1678945972 eth0 36248274 37294982749 56653568 82227069534 ``` Here's what the sample logstash output shows ```auto [2023-03-16T13:04:54,826][WARN][logstash.outputs.elasticsearch][interface_logger_log][8acbe052951cec868f387d4444fb955dc087a4bb4c48c6852ef35b8cee41737d] Could not index event to Elasticsearch. status: 400, action: ["create", {:_id=>nil, :_index=>interfacelogger_lines", :routing=>nil}, {"num_packets_written"=>"3230996", "bytes_written"=>"3577587849", "interface_logger_version"=>"1", "@timestamp"=>2023-03-16T09:45:34.000Z, "bytes_read"=>"632120356", "interface_ip"=>"$REDACTED", "num_packets_read"=>"2566696", "interface"=>"eth0"}], response: {"create"=>{"_index"=>"logstash_interface_logger_lines-000001", "_id"=>"gHmF6oYBVK7ZTxZd_N8N", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse field [bytes_written] of type [byte] in document with id 'gHmF6oYBVK7ZTxZd_N8N'.

This is a mapping issue, the field is mapped as a `byte` but the value is higher than what an byte field would support, this should be mapped as `long`. > [@Shreesh\_Narayanan](#): > > in the component template , i gave the mapping as. "bytes\_written" -\> "numeric/byte" The `byte` here is the _byte_ data type, it only supports values between _-128_ and _127_, this is your issue, the field should be mapped as `long`, you can check the numeric data types in [this documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/number.html). The solution is to change the mapping and recreate the index. ---
