Message Catalog

Each message produced by SolRDF has the following format :

<DATE> <PRIORITY> <MESSAGE-ID> : <MESSAGE>

Where :

• DATE is the date and time at which the message was added
• PRIORITY Could be one of the following : DEBUG, WARN, INFO, ERROR, FATAL
• MESSAGE-ID : the message unique identifier (e.g. SOLRDF-000086)
• MESSAGE the log message

For example

2014-01-15 17:05:42,105 DEBUG <SOLRDF-00090> : Switching to Hybrid mode.

This message catalog is not alternative to what Solr already does in terms of logging. Beside SolRDF log messages you will still have messages coming from Solr, like:

...       
16:31:09,847 INFO  Hard AutoCommit: if uncommited for 15000ms;   
16:31:09,847 INFO  Soft AutoCommit: disabled     
...     
16:35:02,062 INFO  newest commit generation = 2       
16:35:02,087 INFO  [store] Registered new searcher Searcher@7720a996     
...   

The following table lists the whole message catalog. Being SolRDF a work in progress, this catalog is frequently updated.
