+# This scripts job is to continuously run in background and watch for changes in collector.properties
+# and in case it has changed, restart application.
+# collector.properties (and DmaapConfig.json) is being updated periodically by calling for configuration from CBS and it is
+# done inside the VESCollector application itself.
+# Configuration poller can be run regardless of deployment type.
+# It will always check for changes in collector.properties and in deployment scenario,
+# where dynamic configuration should not be used, necessary environment
+# variables that are needed (consul host, cbs name, app name) will be missing, and java app will
+# not update the configuration files so restart won't be triggered.
+
+# Start after a while, because once the application starts, it might happen that
+# it fetched new configuration. In that case, the application will already be started with newest config, there would
+# be no point in restarting it once again.
