Introduction

In addition to the basic user interface of Carte, there are also web services available that provide execution and status information.  These webservices are used by Kettle to orchestrate execution within a clustered environment, but may also be used by third-parties for integration and monitoring.

Carte Status Service

To retrieve status of your Carte node, you can request the following URL:

http://localhost:PORT/kettle/status/?xml=Y

This returns an XML result, here is an example:

<?xml version="1.0" encoding="UTF-8"?>
<serverstatus>
<statusdesc>Online</statusdesc>
  <transstatuslist>
    <transstatus>
      <transname>Row generator test</transname>
      <id>9ae24a18-d97f-46fc-a3b8-35a8f55b2775</id>
      <status_desc>Waiting</status_desc>
      <error_desc/>
      <paused>N</paused>
      <stepstatuslist>
      </stepstatuslist>
      <first_log_line_nr>0</first_log_line_nr>
      <last_log_line_nr>0</last_log_line_nr>
      <logging_string><![CDATA[]]></logging_string>
    </transstatus>
  </transstatuslist>
  <jobstatuslist>
  </jobstatuslist>
</serverstatus>

Transformation Status Service

The following webservice provides status of a specific transformation within Carte:

http://localhost:<PORT>/kettle/transStatus/?xml=y&name=<TRANSFORMATION NAME>&id=<TRANSFORMATION ID>

Note that the Name and ID can be retrieved from the Carte Status webservice above.

Example XML Result:

<?xml version="1.0" encoding="UTF-8"?>
<transstatus>
  <transname>Row generator test</transname>
  <id>9ae24a18-d97f-46fc-a3b8-35a8f55b2775</id>
  <status_desc>Waiting</status_desc>
  <error_desc/>
  <paused>N</paused>
  <stepstatuslist>
  </stepstatuslist>
  <first_log_line_nr>0</first_log_line_nr>
  <last_log_line_nr>2</last_log_line_nr>
  <logging_string><![CDATA[H4sIAAAAAAAAAAMAAAAAAAAAAAA=]]></logging_string>
</transstatus>

Job Status Service

The following webservice provides status of a specific job within Carte:

http://localhost:<PORT>/kettle/jobStatus/?xml=y&name=<JOB NAME>&id=<JOB ID>
