Header-based variables don't send to elastic

[leonsery]

I added the following headers into JMeter:

I can see them in the traffic:

Unfortunately, corresponding variables don't appear in the elastic index!

Could you provide me with your whole listener configuration? Thanks

Should I change es.parse.all.req.headers to true?
Yes! It seems to be true. Please mention this somewhere in the help

[leonsery]

Looking to your code I found that to parse headers allReqHeaders should be set true. private void parseHeadersAsJsonProps(boolean allReqHeaders, boolean allResHeaders) { LinkedList<String[]> headersArrayList = new LinkedList<String[]>(); if (allReqHeaders) { headersArrayList .add(this.sampleResult.getRequestHeaders().split("\n")); } if (allResHeaders) { headersArrayList.add(this.sampleResult.getResponseHeaders().split("\n")); } for(String[] lines : headersArrayList) { for(int i=0; i < lines.length; i++) { String[] header = lines[i].split(":",2); // if not all req headers and header contains special X-tag if (header.length > 1) { if (!this.allReqHeaders && header[0].startsWith("X-es-backend")) { =>> this.json.put(header[0].replaceAll("es-", "").trim(), header[1].trim()); } else { =>> this.json.put(header[0].replaceAll("es-", "").trim(), header[1].trim()); } } } } } When I set it true - I finally got the variables. But, looking in your code I found something strange - marked by =>> lines are literally the same, isn't it? So why do you have if-else clause? Regards, Leon Sery.

[anthonygauthier]

Very true, the if-else clause isn't needed in this case. Probably some left over code that wasn't cleaned up probably during a refactor.

[leonsery]

Anthony!
There is some issue here...
To send updatable variable we need to use es-[...] syntax AND set all requests to true. But in this case listener sends ALL the headers (es-[...] and also NOT es-[...]). So, why we should provide this es- prefix at all?
I'm sorry, something wrong here.

[anthonygauthier]

The following condition states that;

if (!this.allReqHeaders && header[0].startsWith("X-es-backend") || this.allReqHeaders)

IF allReqHeaders IS false AND the current header starts with "X-es-backend" 
  OR IF allReqHeaders IS true 
THEN add the header to the ElasticSearch document 

The doc is wrong, I'll fix it.

[anthonygauthier]

I have reuploaded the JAR for the 2.6.9 release - please replace the one you are currently using.

[leonsery]

Sorry, I didn't understand what exactly should I do to send my custom updatable parameter without sending all other headers? 2019-09-09 16:59 GMT+03:00, Anthony Gauthier <notifications@github.com>:

@leonsery First of all, replace your JAR with the new one (2.6.9 - same version, just a re-upload).

Then you'll have to change your headers to look like this

X-es-backend-{{ yourVariableName }}: {{ yourVariableValue }}

[leonsery]

Hi,
I back to my project only now...
I cannot get this work anyway...
According to this code

       LinkedList<String[]> headersArrayList = new LinkedList<String[]>();
       if (allReqHeaders) {
            headersArrayList.add(this.sampleResult.getRequestHeaders().split("\n"));
       }

headersArrayList is populated ONLY when allReqHeaders is True.
So, I definitely must to set it to True.

But, in this case the following statement is always false!
!this.allReqHeaders && header[0].startsWith("X-es-backend")

This means it will send or all the headers or nothing!
I don't need to send all the headers to elastic, but only started with "X-es-backend".
