[jira] Created: (QPID-1908) cluster_manager -- testing tool
cluster_manager -- testing tool
-------------------------------
Key: QPID-1908
URL: https://issues.apache.org/jira/browse/QPID-1908
Project: Qpid
Issue Type: Improvement
Components: C++ Broker
Reporter: michael j. goulish
cluster_manager will start a cluster on a set of host:port URLs that you specify on the command line.
The hosts can all be different -- so long as they are all clustered and have openais running on them.
It will then periodically check the qpid cluster and make sure that there are syill brokers running at the expected places.
( For this, it uses ssh and reads /proc . )
If it finds that one or more brokers are missing, it will start new brokers to replace them.
This will allows us to run long-term tests in which the clients start and stop (or are killed) during the test -- they will always know what set of host:ports to attach to. Clients can be written either to try one host:port after the other until they connect (which is functionality available from the client library) -- or so that they try a single host:port -- then wait 30 seconds or so and retry if it doesn't work the first time.
( Because of the use of ssh, this is not a very high-speed application. It often takes more than 30 seconds to check on a cluster of 3 brokers. )
