Logging & Error Handling

Broadcast Log Message

TQLEngine allows users to provide facet id on which all the log messages can be broadcast.

To Configure broadcast of message:

<SffLocalConfig>
    <sff.log.broadcast.all>loggerfacet</sff.log.broadcast.all>
    <sff.log.broadcast.message>json</sff.log.broadcast.message>
</SffLocalConfig>

Explanation

• sff.log.broadcast.<log level name> which defines one or more facet IDs used for log broadcasting. That is:
  •  <sff.log.broadcast.error>[:MyErrorsFacet:]</sff.log.broadcast.error> - This one will broadcast log error messages to [randomized] [:MyErrorsFacet:] fid 
  • <sff.log.broadcast.all>wstest</sff.log.broadcast.all> - This one will log messages to wstest fid.
    You can specify more than one fid as comma-separated list.
  • Known Log levels are: 
  1. 1. text
     2. trace
     3. debug
     4. info
     5. warn
     6. error
     7. fatal
     8. all

• sff.log.broadcast.protocol. Default value is “ws,wss”. This is the list of protocols which will be used to select broadcast pipelines. That is, it will *not* broadcast on HTTP connections, for example. When broadcast is enabled, startup will log the list of protocols so you know it was enabled. Obviously, it will *not* print the list of facet IDs used for broadcast.

• sff.log.broadcast.message. This is log message definition. It may come in different forms:

• <sff.log.broadcast.message>json<sff.log.broadcast.message> This simplest form allows you to define log message type (e.g. xml or json). Default is xml.

• Default message will look like this:
