It is +designed to scale to a very large number of nodes and be robust to network +and node failures. + +See the Scribe Wiki [1] for more information on Scribe. + +Getting the required Apache Thrift library +========================================== +This sample uses Apache Thrift's libthrift.jar to communicate with Scribe +servers. Libthrift is not yet available in a Maven repository, so before +building the sample with Maven, you need to download libthrift [2] and +install it in your local Maven repository like this: + +mvn install:install-file -DgroupId=org.apache.thrift -DartifactId=libthrift \ +-Dversion=1.0-SNAPSHOT -Dpackaging=jar -Dfile=libthrift-r917130.jar + +Starting a Scribe server +======================== +Before running the LoggingTest sample test program, you need to start a Scribe +server for the sample program to connect to. + +Steps to start a Scribe server are described in the Scribe examples README [3]. +A simple Scribe server configuration can be found in the Scribe examples [4]. + +LoggingTest will try to connect to a Scribe server at localhost:1463. To use +a Scribe server at a different host or port, configure the host and port +properties in scribe.composite to match your server. + +Running the LoggingTest sample test program +=========================================== + +To run the LoggingTest sample test program, do this: +mvn -Dtest=LoggingTest test + +Checking the Scribe log output +============================== +After running LoggingTest, you should find the logged string "Hello There" in +file sample/sample_current under your Scribe log store directory. + +If you've used the example1.conf Scribe configuration from the Scribe examples +[4], you should find your log message in /tmp/scribetest/sample/sample_current. + + +[1] http://wiki.github.com/facebook/scribe/ +[2] http://svn.apache.org/repos/asf/cassandra/trunk/lib/libthrift-r917130.jar +[3] http://github.com/facebook/scribe/blob/master/examples/README +[4] http://github.com/facebook/scribe/blob/master/examples/example1.conf + |
