Check Compact SP Deployment Proxy Setting in case Content Extraction fails

Mar 2023

Introduction


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:

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”,

Save the file and we can test the result.

First restart the ericsson-stream-processing-content-extraction process 

  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 before, but hopefully with a different output:

Hint: Some lines were ellipsized, use -l to show in full.

Now we can see that the Proxy enabled is missing, and there are a bunch of lines that end with “Registering xxxx” 

"Registering with interface discovery ETCD at http://10.43.30.119:2379"}
"Registering server name SP02"}
"Registering interfaces eth2,eth3,eth4,eth5,eth0,eth1"}
"Registering location http://10.43.30.116:8082"}

We can see the VIP of the MKSP units, the server name etc, so this means that comms are now good. You can now retry the Content Extraction.

DONT FORGET TO DO THIS ON BOTH MKSP UNITS
