Logstash csvparsefailure和dateparsefailure

Question

I am using this filter to parse some csv data that I am generating from a php file. I am taking the output from a gpu monitoring tool called msi afterburner which outputs a .hml file. There are a tonne of white spaces and an irrelevant header which my php file removes and outputs comma separated value.

 filter 
    {
        csv 
        {
            columns => ["somename","@timestamp","cpu.avg.temp","gpu.temp","fan.speed","gpu.usage","bus.usage","fan.tachometer","clock.core","framerate.hz","framerate.ms","cpu.temp.1","cpu.temp.2","cpu.temp.3","cpu.temp.4"]
            separator => ","
            skip_empty_columns => "true"
        }
        mutate 
        {
            convert => ["somename","integer"]
            convert => ["cpu.avg.temp","float"]
            convert => ["gpu.temp","float"]
            convert => ["fan.speed","float"]
            convert => ["gpu.usage","float"]
            convert => ["bus.usage","float"]
            convert => ["fan.tachometer","float"]
            convert => ["clock.core", "float"]
            convert => ["framerate.hz","float"]
            convert => ["framerate.ms","float"]
            convert => ["cpu.temp.1","float"]
            convert => ["cpu.temp.2","float"]
            convert => ["cpu.temp.3","float"]
            convert => ["cpu.temp.4","float"]
        }
        date 
        {
            match => ["@timestamp", "dd-MM-yyyyHH:mm:ss"]
        }
    }

This is the output logstash is throwing at me. I am wondering if this is due to the fact that my date format is bad or if at the end of my message there appears to be a special character ''. I am wondering if logstash is even able to read dd-MM-yyyyHH:mm:ss format where year and hour are stuck together, if not I might be in a bit of trouble.

{
          "path" => "C:\\Users\\Public\\Documents\\gpumetrics.csv",
      "somename" => 80,
    "@timestamp" => 2017-02-20T02:33:10.764Z,
      "@version" => "1",
          "host" => "DESKTOP-Q8UEATO",
       "message" => "80,19-02-201721:33:10,32.000,41.000,0.000,0.000,0.000,0.000,215.000,0.000,0.000,31.000,32.000,30.000,31.000",
          "type" => "csv",
          "tags" => [
        [0] "_csvparsefailure",
        [1] "_dateparsefailure"
    ]
} 

Here are a few sample lines from my log file. As you may notice, there is a field before timestamp. I am wondering if this is allowed.

Your problem can be solved very simply by changing the name of your timestamp variable since @timestamp is created internally before your line is parsed.

filter 
    {
        csv 
        {
                               remove the @
                                    |
                                    v
            columns => ["somename","timestamp","cpu.avg.temp","gpu.temp","fan.speed","gpu.usage","bus.usage","fan.tachometer","clock.core","framerate.hz","framerate.ms","cpu.temp.1","cpu.temp.2","cpu.temp.3","cpu.temp.4"]
            separator => ","
            skip_empty_columns => "true"
        }
        ...
        date 
        {
            match => ["timestamp", "dd-MM-yyyyHH:mm:ss"]
                       ^
                       |
                  remove the @
        }
    }
