ETA - Enable logging in Consumer application

Hi,

Can you please advise how we can turn on logging in ETA (I am working from the basicConsumer.java tutorials)

Ideally I want to generate output similar to below (which was shown to me by a Refinitiv Technical specialist):

1) Service: ELEKTRON_DD ConnectionType: rssl ServerHostname: localhost SipcVersion: 4
Number of Connection Count = 1
Creating RSSL connection Host: localhost Port: 14002
UPA server component version: ads_edge2.5.6.win 64-bit (ssl7.1.F30)
Setting rmds connection 0000000001EAF720
Connection list count is 1

Hi @anand.pankhania,

ETA is a zero-configuration environment so to turn on tracing you have to do it through code. Within Chapter 10 of the ETA Developers guide, there is a section called XML Tracing which provides some details.

To see an example, you can look at the rsslConsumer.c example within the Eta\Applications\Examples\Consumer directory within the ESDK package.

Hello @anand.pankhania,

In addition (totally agreeing with @nick.zincone), if you are looking to parse and present News Analytics domain, MRN content, using ETA Java, you may benefit from reviewing ETA Tutorial 6 - Request & Decode Machine Readable News

If it's a new application being designed, you may consider saving time and effort, by using higher level EMA Java implementation EMA Consumer - Request & Decode Machine Readable News

Thanks @zoya faberov and @nick.zincone, and ,,

Our requirement is to transition from the NFD service which is end of life. As a result, we are moving to the ETA which offers comparable ultra low latency performance.

I am using ETA Java API, and have found the following option to turn on XML tracing: reactorOptions.enableXmlTracing();

I couldn't find any documentation on this in the docs in https://github.com/Refinitiv/Elektron-SDK/blob/master/Java/Eta/Docs/. Is there an equivalent section about XML Tracing for the ETA Java API?

In addition to this, just wanted to mention that I am using the ETA Tutorial 6 (Request and Decode MRN) as a starting point.

Hi @anand.pankhania,

It appears that the ETA for Java does its XML tracing through the Msg interface. The Msg interface is a subclass of XMLDecoder which can be used to log your messages to stdout, file, etc.

You see how it is utilized within the Eta\Applications\Examples\src\main\java\com\thomsonreuters\upa\examples\consumer folder. That example has a -x switch which dumps trace message to XML. It references the ChannelSession.java class within the common folder.

Hi @anand.pankhania,

Given you are using MRN as your source of content, it might be worth considering using EMA Java as opposed to the effort involved in using ETA Java. Where ETA really shines is for those services of data where the throughput is high and you want to have complete control over performance. Given MRN is not a high throughput service, it might be something to consider.
