NEW: Cleanup heartbeat values after a period of time: store daily, weekly, monthly, quarterly and yearly values NEW: Display heartbeat for certain periods: last 24 hours, daily, weekly, monthly, quarterly and yearly NEW: Heartbeat is looking for the last 5 minutes if there is no record available yet NEW: If module "chart" is enabled then the dashboard can display nice charts for the collected data NEW: Collect file data and watchdog info during heartbeat NEW: Collect heartbeat info from all domains during cron. This can be used to implement a regular monitoring system, the data gets collected in a new database table NEW: We now get feedback from remote sites if there is a encryption key mismatch and provide a link in the error message to define new encryption keys CHANGE: Code improvement around chart creation CHANGE: Heartbeat on domain lists is now disabled by default CHANGE: Operations list: use a default group for orphaned items and then sort groups and their items alphabetically CHANGE: Collect operations from all domains, not just from the main domain CHANGE: Properly merge subform from remote server when editing server settings and do the same thing for domains as well CHANGE: Show a "Wait" message while Ajax grabs historical data CHANGE: Properly manage the changing content in the info-pane of a server/domain FIX: Find the correct last value for heartbeat requests FIX: Heartbeat toggle button now also works in the fixed table header FIX: User the correct object (server vs domain) in building messages FIX: Edit server details now allows colons but still not protocolls
