Talend Administrator/Viewer/Operation manager/Designer can be used for various purposes. One of my team member is accountable monitor the success/failure of Talend jobs every 6 hours! In addition to being a manual task the execution plan pane use to refresh every 15 seconds, most of the time it use to refresh before completely loading and analyst spends more than an hour for this monitoring.
Solution: Auto refresh setting cannot be modified through UI but it can be changed in the configuration file. Search for the configuration file (configuration.properties) at \webapps\org.talend.administrator\WEB-INF\classes and update the setting of scheduler.conf.uiAutoRefreshFrequency parameter to a new value.
Seems to be a simple problem but it really helped to save at least an hour every day for analyst!
