It is your responsibility to properly monitor your deployments of Tungsten Replicator. The minimum level of monitoring must be done at two levels. Additional monitors may be run depending on your environment but these three are required in order to ensure availability and uptime.
Make sure the appropriate Tungsten Replicator services are running.
Make sure replication latency is within an acceptable range.
Special consideration must be taken if you have multiple installations on a single server.
These two points must be checked for all directories where Tungsten Replicator are installed, and all services. In addition, all servers should be monitored for basic health of the processors, disk and network. Proper alerting and graphing will prevent many issues that will cause system failures.
