This is pertaining to an SP release in LB 5.0.9 (but not necessarily limited to this release) where there seems to be a bug with running Compact Mode and Content Extraction.

For some reason there is a process called ericsson-stream-processing-content-extraction that is being setup internally with a 'proxy'. The proxy is for comms between the service and whatever calls it in a containerised system, not in a RPM system. The proxy has to be removed, which thankfully is very simple.

To work out the status of the proxy setting we need to check the status of a service, however to get the latest status of the service we need to restart it, this can be done using the following:

  systemctl restart ericsson-stream-processing-content-extraction

There is no feedback from this command line.

To check the status of the service use the following:

  systemctl status ericsson-stream-processing-content-extraction

This will give an output similar to the following:

● ericsson-stream-processing-content-extraction.service - ericsson-stream-processing-content-extraction

The important line here is about halfway down and ends with:

  "ContentExtraction.Startup","msg":"Proxy mode enabled."}

If we see the text Proxy mode enabled then Content Extraction will fail.

To rectify this we need to edit just one file, the file is located in the following location:

  cd /opt/ericsson/stream-processing-content-extraction/lib

In this location find the file appsettings.json and open it in your favourite text editor (or vi).

Around 5 lines from the bottom of the file we will see the entry “enabled”: “true”,

  "houseKeepingFrequency": "00:01:00",
  "allowedIdleTime": "00:02:00",
  "proxy": {
    "enabled": "true",
    "interfaceDiscoveryAPI": "http://localhost:8200/api/discoveries",
    "serverOfLastResort": ""
  }
}

We need to set this to “enabled”: “false”,
