Bytes value wraps to negative value

[eddie4]

Hello,

Am attempting to multiply the number of bytes from netflow by 100. This is to offset the sampling rate.

The pipeline has the following script:

  {
    "script": {
      "source": "ctx.network.true_bytes2 = ctx.source.bytes * 100;"
    }
  },

Both fields are long's so A signed 64-bit integer. Which should allow me more then enough room to store this data usage. However I can see that the true_bytes seems to be wraping ( overflowing and starting at minus value).

The results are fine under the 20MB. I am truly at a loss what could be the cause of this issue.

Issue seems to be solved when defining the variable as a long.

Why you need to cast a long to a long when it already is a long dunno. But it solved the issue.

"script": {
  "source": "long bytes = ctx.source.bytes;\r\nctx.network.true_bytes = bytes * 100;"
}
