I am trying to use Filebeat 7.5.1 to parse a timestamp with the following format: '2020-01-17 06:37:17,849'
My layout is this: '2006-01-02 15:04:05,999'
Unfortunately, the above does not work. According to Golang docs, I need to define milliseconds with a period (e.g., ".999"). Indeed, if I change both the sample and the layout to use a period, it works. I am linking here the Go Playground for this.
Is there a way to get the timestamp processor to do what I need it to do? If not, is there some other way to get around this? For example, I couldn't find a way to concatenate fields, otherwise I could possibly use a dissect processor to split the comma out, and then join the fields with a period in the middle.
Any help is appreciated.
