Node Checker Improvements: Better Organization and Readability

Changes

This PR improves the organization and readability of the node checker script by:

Security Section

Organized security checks into clear categories:
- Network Security (firewall, fail2ban)
- SSH Security (keys, port, 2FA)
- System Updates (updates, unattended upgrades, reboot)
Moved SSH-related checks from Node Health to Security section
Improved order of SSH security checks for better logical flow

Performance Section

Reorganized performance checks for better flow:
- System resources (memory, CPU, disk)
- Time synchronization
- System tuning (swappiness, noatime)

General Improvements

Added clear section headers for better readability
Consolidated redundant headers
Improved spacing between sections
Better organization of node health checks

Testing

Verified all checks still function as expected
Confirmed proper categorization of all checks
Tested output formatting and readability

Impact

These changes improve the user experience by:

Making it easier to find and understand related checks
Providing clearer organization of security-related items
Improving the logical flow of the checks
Making the output more readable and maintainable

Summary by CodeRabbit

New Features
- Added a check to display Ethereum node processes during system checks.
Improvements
- Enhanced the organization and grouping of security, health, and performance checks for clearer output.

Walkthrough

The script in plugins/node-checker/run.sh was refactored to improve the organization and sequencing of node security and health checks. A new function was introduced to display Ethereum node processes, output formatting was adjusted, and a missing brace was fixed. The execution order of checks was logically regrouped.

Changes

File(s)	Change Summary
plugins/node-checker/run.sh	Added `check_elcl_processes` function; fixed missing closing brace in `check_elcl_listening_ports`; updated `check_systemd_services` to call the new function and adjust output; reorganized and grouped checks with new info headers and reordered execution flow.

Poem

🐇
In scripts we hop, rearrange, and mend,
With checks in order, our logic we send.
A process peek, a brace now found,
Security and health, all neatly wound.
With every tweak, this bunny grins—
For tidy scripts are where joy begins!

⚠️ Potential issue

Ensure the New check_elcl_processes Function Updates Counters
The newly added check_elcl_processes() outputs PASS/FAIL but does not increment total_checks, failed_checks, or warning_checks. This will skew the summary counts.

Please introduce counter increments, for example:
+    ((total_checks++))
     for process in "${p2p_processes[@]}"; do
         if pgrep -f "$process" >/dev/null; then
             …
         fi
     done
     if [ $running_p2p -gt 0 ]; then
+        # successful detection counted as PASS
         print_check_result "PASS" "Found ${running_p2p} Ethereum node processes running"
     else
+        ((failed_checks++))
         print_check_result "FAIL" "No Ethereum node processes detected"
     fi

🧹 Nitpick comments (2)

plugins/node-checker/run.sh (2)

586-588: Indent and Context for check_elcl_processes Invocation
The call to check_elcl_processes and the standalone echo are unindented inside check_systemd_services(). For readability, indent them to match the function body and consider using print_check_result "INFO" for consistent header styling.

861-864: Approve: Node Health Check Sequence Adjustment
Moving check_peer_count immediately after check_elcl_listening_ports() and surrounding with blank lines improves readability of health checks.

You might replace the blank echo calls with a lightweight section header function for consistency.

plugins/node-checker/run.sh (5)

475-478: Closing Brace Added for check_elcl_listening_ports
The missing } at the end of check_elcl_listening_ports() has been restored, preventing a potential syntax error.

839-844: Approve: Network Security Section Header and Ordering
Grouping firewall and fail2ban under a clear # Network Security with an INFO header improves clarity and logical flow. Good use of print_check_result to denote a subsection.

845-851: Approve: SSH Security Section Reorganization
Relocating SSH‐related checks into a dedicated # SSH Security block with its own INFO header enhances discoverability. The sequence (key_presence, key_auth, port, 2FA) is logical.

852-856: Approve: System Updates Section Consolidation
Consolidating update checks under # System Updates and prefixing with an INFO header makes maintenance easier. All three update‐related checks are appropriately grouped.

873-877: Approve: Renamed and Reordered Performance Checks
Changing to print_section_header "Performance Checks" and listing resource, time sync, and tuning checks in a clear order greatly enhances logical flow.
