Updated monitor/monitor.sh to version 1.2.3.
Removed the redundant else block in the send_notification_if_changed() function in monitor/monitor.sh as it provided no functional change.
Updated the "Monitor Suite" version in packages.conf to 1.2.3 to reflect the script update.
Removed incorrect 'local' keyword from global variable declarations in monitor/monitor.sh as it's only valid within functions. Updated version to 1.2.1 in monitor/monitor.sh and packages.conf.
Introduces state management to 'monitor.sh' to send notifications only when a monitored status changes (e.g., from healthy to alert, or alert to resolved). This prevents repetitive alerts for persistent issues. Creates a 'monitor_state' directory for tracking. Updates script version to 1.2.0.
Fixes an issue in 'monitor.sh' where the HANA backup monitoring used incorrect variable names ('HANA_USERKEY' instead of 'HANA_USER_KEY') and did not explicitly use the configured 'HDBSQL_PATH' for the 'hdbsql' command. Updates script version to 1.1.1.
Introduces a new monitoring check in 'monitor.sh' to verify the age of the last successful SAP HANA data backup. Alerts are sent if the backup age exceeds a configurable 'BACKUP_THRESHOLD_HOURS'. Updates script version to 1.1.0.
