73-80: LGTM: Improved signal handling for graceful shutdownsThe updates to the
handle_sigtermfunction now ensure graceful shutdown of all processes, including the Redis exporter and health check. This is a good improvement for overall system stability.Consider adding a small delay (e.g.,
sleep 1) after each kill command to allow processes to shut down gracefully before the script exits. This can help prevent any race conditions during shutdown. For example:if [[ $RUN_METRICS -eq 1 && ! -z $redis_exporter_pid ]]; then kill -TERM $redis_exporter_pid + sleep 1 fi if [[ $RUN_HEALTH_CHECK -eq 1 && ! -z $healthcheck_pid ]]; then kill -TERM $healthcheck_pid + sleep 1 fifalkordb-node/node-entrypoint.sh (1)
466-466: LGTM: Proper usage of the new DEBUG_REDIS_EXPORTER variable.The
DEBUG_REDIS_EXPORTERvalue is correctly exported asREDIS_EXPORTER_DEBUG, allowing for independent control of the Redis exporter's debug mode. This change enhances the configurability of the system.For consistency with other environment variable usage in the script, consider using the following syntax:
- export REDIS_EXPORTER_DEBUG="$DEBUG_REDIS_EXPORTER" + export REDIS_EXPORTER_DEBUG=${DEBUG_REDIS_EXPORTER:-false}This change would ensure that if
DEBUG_REDIS_EXPORTERis unset, it defaults tofalse, maintaining consistency with how other variables are handled in the script.

48-48: LGTM: New DEBUG_REDIS_EXPORTER variable addedThe addition of the
DEBUG_REDIS_EXPORTERvariable with a default value of 'false' aligns well with the PR objective. It provides a separate control for Redis exporter debugging, which enhances the configurability of the system.
304-304: LGTM: Enhanced Redis exporter configuration and process managementThe addition of
export REDIS_EXPORTER_DEBUG="$DEBUG_REDIS_EXPORTER"allows for dynamic control of the Redis exporter's debug mode. Capturing theredis_exporter_pidenables graceful shutdown of the exporter process, which is consistent with the earlier changes to thehandle_sigtermfunction.These modifications improve the overall manageability and configurability of the Redis exporter within the FalkorDB cluster setup.
Also applies to: 307-307

1-311: Overall assessment: Changes look good with minor suggestions for improvementThe changes introduced in this PR successfully implement the new
DEBUG_REDIS_EXPORTERvariable and improve the process management for graceful shutdowns. These modifications align well with the PR objectives and enhance the configurability and stability of the FalkorDB cluster setup.A few minor suggestions have been made to further improve error handling, logging, and the shutdown process. These suggestions, if implemented, would contribute to making the script more robust and easier to troubleshoot.
Great job on these improvements!

1099-1102: Appropriate addition of DEBUG_REDIS_EXPORTER variableThe new environment variable
DEBUG_REDIS_EXPORTER=falsehas been correctly added to thenode-szservice configuration. This addition aligns with the PR objective and provides a dedicated control for Redis exporter debugging.
Line range hint
1173-1177: Consistent addition of DEBUG_REDIS_EXPORTER to sentinel serviceThe
DEBUG_REDIS_EXPORTER=falsevariable has been appropriately added to thesentinel-szservice configuration. This ensures consistent debugging control across both node and sentinel services in the Single-Zone setup.
Line range hint
1584-1589: Consistent implementation in Multi-Zone configurationThe
DEBUG_REDIS_EXPORTER=falsevariable has been correctly added to thenode-mzservice in the Multi-Zone configuration. This demonstrates consistency in implementing the new debug control across different deployment scenarios.
Line range hint
1658-1664: Comprehensive implementation across all servicesThe
DEBUG_REDIS_EXPORTER=falsevariable has been appropriately added to thesentinel-mzservice in the Multi-Zone configuration. This change completes the implementation across all relevant services, ensuring a consistent approach to Redis exporter debugging control.
Line range hint
1969-1976: Extension to cluster rebalance serviceThe
DEBUG_REDIS_EXPORTER=falsevariable has been correctly added to thecluster-sz-rebalanceservice in the Cluster Single-Zone configuration. This extends the Redis exporter debug control to the cluster rebalancing process, ensuring comprehensive coverage across all components.
Line range hint
2265-2273: Complete implementation across all deployment scenariosThe
DEBUG_REDIS_EXPORTER=falsevariable has been successfully added to thecluster-mz-rebalanceservice in the Cluster Multi-Zone configuration. This final addition ensures that the Redis exporter debug control is consistently implemented across all deployment scenarios, including standalone, single-zone, multi-zone, and cluster configurations.
Line range hint
1099-2273: Summary: Comprehensive implementation of Redis exporter debug controlThe changes in this PR successfully introduce the
DEBUG_REDIS_EXPORTER=falseenvironment variable across all relevant services in the FalkorDB deployment configuration. This implementation:
- Covers all deployment scenarios: standalone, single-zone, multi-zone, and cluster configurations.
- Maintains consistency across node, sentinel, and cluster rebalance services.
- Aligns perfectly with the PR objective to add a separate environment variable for controlling Redis exporter debugging.
The default value of
falseis appropriate for production environments, while still allowing easy enablement for debugging purposes when needed. This change enhances the configurability and usability of the Redis exporter within the FalkorDB system.

🛠️ Refactor suggestion
Consider enhancing error handling and logging for Redis exporter
While the changes look good, consider adding error handling and logging for the Redis exporter startup. This can help with troubleshooting if there are issues with the exporter, especially when debug mode is enabled.
Here's a suggestion to improve this section:
echo "Starting Metrics"
export REDIS_EXPORTER_DEBUG="$DEBUG_REDIS_EXPORTER"
exporter_url=$(if [[ $TLS == "true" ]]; then echo "rediss://$NODE_HOST:$NODE_PORT"; else echo "redis://localhost:$NODE_PORT"; fi)
-redis_exporter -skip-tls-verification -redis.password $ADMIN_PASSWORD -redis.addr $exporter_url -log-format json -is-cluster | awk '{ print "**EXPORTER**: " $0 }' >>$FALKORDB_LOG_FILE_PATH &
-redis_exporter_pid=$!
+redis_exporter -skip-tls-verification -redis.password $ADMIN_PASSWORD -redis.addr $exporter_url -log-format json -is-cluster | awk '{ print "**EXPORTER**: " $0 }' >>$FALKORDB_LOG_FILE_PATH 2>&1 &
+redis_exporter_pid=$!
+if [ $? -ne 0 ]; then
+ echo "Failed to start Redis exporter" >&2
+ exit 1
+fi
+echo "Redis exporter started with PID $redis_exporter_pid"This change adds error handling for the Redis exporter startup and logs the PID when it starts successfully. It also ensures that any error messages from the exporter are captured in the log file.
