Use content filter on Recording service

I'm using recording service with RTI DDS Connext 6.1.2 to capture data of type KeyedString on the same topic name ('MOVEMENT_LINE') 

The key is a normal string, and the value is an xml content. 

Bellow example of data where some messages are used as responses and others as requests: 

 

[

  {

    "key": "2b44272e-694c-4666-a3f3-0ad125812042",

Recording Service - Record Only Valid Samples

I recently noticed that our RTI recording service is recording occasional invalid samples under the NOT_ALIVE_NO_WRITERS_INSTANCE_STATE. SampleInfo valid data is false.

This was first noticed when looking at the recording service metadata.db Files_2_0 table. The first shard of the recording session state that the minimum SampleInfo_source_timstamp was -1000000000.

This is a potential issue for our software.

Retrieve integer enumeration value

Hello!

I'm reading a dds log file using sqlite and having troubles to retrieve the original integer values that were specified for enumerations in my *.idl file.

For example:

enum tTest
{
  Value0,
  Value1, 
  Value2
}

struct tMyData
{
  tTest testData;
}; 

When I read testData, I want to get the integer values 0,1 or 2. But instead the json string contains "Value0", "Value1" or "Value2". Is there some setting that I miss during the recording?

Any help is highly appreciated!

/David

File metadata and Recording Service

Hi.

We've been prototyping with the RTI Recording Service for a bit with two different plugins and it seems to work well overall but it does seem like we could need some help.

Play back data recorded using the Recording Service

Hi,

I've recorded data using the Recording Service (RTI Connext v6.0.1) and I'd like to play it back but on another machine that doesn't have RTI DDS installed.

Is it possible? I've looked for this functionality in the RTI Connector for Python (https://community.rti.com/static/documentation/connector/current/api/python/index.html) but didn't have much luck with it.

Thanks for your help / suggestions!

How to extract data from an XCDR recorded file?

Hi,  

I was wondering if there's a way I can extract a sample (for example first and last sample) from an XCDR log file generated using the Recording Service?

I understand this can be done if I use the Converter service and convert my log file into JSON format. However I'm using rather large data, and the process of converting the whole log file will take significant time when I just need to extract a few samples from that file.

|------image_types.xml

|------coordinate_systems.xml

|---MY_RECORDING_SERVICE.xml

 

Inside my MY_RECORDING_SERVICE.xml I'm including these xml generated as follow:

Error with multicast using FlatData and Zero Copy

I'm sending images using a docker. I created a publisher and subscriber which sends a simple image. And I want to use the recording service to log info from this images. 

I created this xml, based on the example in the RTI_RecordingService_UsersManual.pdf page 27.

 

<?xml version="1.0" encoding="UTF-8"?>

Recording other vendors' data

Hi

I want to know whether it is possible to record other vendors' (e.g OpenSplice ...) data with recording service or not. I have tried to do that but got the following error :

"Failed to get valid typecode information for Publisher of Topic 'SampleStatus'. Recorder will NOT be able to record type 'DDSPackets::Main::IDL_Status::payload' in deserialized mode".

Thanks in advance for your help.
