Remove SAPCONTROL_PATH and HDBSQL_PATH variables from configuration.
Update scripts to rely on the system PATH environment variable when
executing as the <sid>adm user. Remove redundant existence checks for
these commands.
- Remove consecutive breach tracking for statement queue (immediate alerts)
- Consolidate script initialization into init_script() function
- Remove unused helper functions (send_ok, run_as_hana_user, get_mount_point)
- Flatten sld_watchdog.sh structure by removing main() wrapper
- Remove state directory and lock directory configuration from hana.conf
- Simplify alert messages to include threshold values
This continues the simplification effort from previous commits by removing stateful tracking mechanisms and streamlining the monitoring logic for easier maintenance.
- Replace state-based notifications with direct alert functions
- Remove auto-cleanup functionality from disk monitoring and configuration
- Simplify lock acquisition/release across all monitoring scripts
- Add execute_hana_sql helper functions for consistent SQL execution
- Remove state file tracking in favor of direct file operations
- Standardize error handling with exit codes on critical failures
- Clean up hana.conf by removing unused auto-delete directory settings
Rename configuration variables and functions to reflect broader
functionality beyond just log files. Updates include renaming
LOG_DIRS_FOR_CLEANUP to DIRS_FOR_AUTODELETE and
clean_log_files to clean_directory_files. Adds safety warnings
to prevent deletion of critical HANA system logs.
BREAKING CHANGE: Config keys renamed from LOG_DIRS_FOR_CLEANUP to
DIRS_FOR_AUTODELETE and MAX_LOG_FILE_AGE_DAYS to MAX_FILE_AGE_DAYS
