Detailed Description

SMART disk health collector implementing the collector_plugin interface

Collects S.M.A.R.T. disk health data using smartctl (smartmontools). Gracefully degrades when smartctl is not available or disks don't support SMART.

Member Function Documentation

add_disk_metrics()

void kcenon::monitoring::smart_collector::add_disk_metrics ( std::vector< metric > & metrics, const smart_disk_metrics & disk )

private

collect()

auto kcenon::monitoring::smart_collector::collect ( ) -> std::vector< metric >

overridevirtual

Collect current metrics from this plugin.

Returns

Vector of collected metrics

This method is called periodically based on interval(). Implementations should:

• Return quickly (< 100ms recommended)
• Handle errors gracefully (return empty vector on failure)
• Be thread-safe if concurrent collection is enabled
• Avoid blocking I/O when possible

Implements kcenon::monitoring::collector_plugin.

create_metric()

metric kcenon::monitoring::smart_collector::create_metric ( const std::string & name, double value, const smart_disk_metrics & disk, const std::string & unit = "" ) const

private

get_last_metrics()

std::vector< smart_disk_metrics > kcenon::monitoring::smart_collector::get_last_metrics

(

)

const

Get last collected SMART metrics

Returns

Vector of SMART disk metrics

get_metric_types()

auto kcenon::monitoring::smart_collector::get_metric_types ( ) const -> std::vector< std::string >

overridevirtual

Get supported metric types.

Returns

Vector of metric type names this plugin produces

Used for filtering and documentation.

Implements kcenon::monitoring::collector_plugin.

get_statistics()

std::unordered_map< std::string, double > kcenon::monitoring::smart_collector::get_statistics ( ) const

overridevirtual

Get collector statistics

Returns

Map of statistic name to value

Reimplemented from kcenon::monitoring::collector_plugin.

initialize()

bool kcenon::monitoring::smart_collector::initialize ( const std::unordered_map< std::string, std::string > & config )

overridevirtual

Initialize the collector with configuration

Parameters

config

Configuration options

Returns

true if initialization successful

Reimplemented from kcenon::monitoring::collector_plugin.

interval()

auto kcenon::monitoring::smart_collector::interval ( ) const -> std::chrono::milliseconds

inlineoverridevirtual

Get the collection interval for this plugin.

Returns

Collection interval in milliseconds

The registry uses this value to schedule collection tasks. Typical values:

• Fast metrics (CPU, memory): 1-5 seconds
• Slow metrics (disk, network): 10-60 seconds
• Very slow metrics (SMART data): 5-15 minutes

Implements kcenon::monitoring::collector_plugin.

Definition at line 135 of file smart_collector.h.

{ return collection_interval_; }

References collection_interval_.

is_available()

auto kcenon::monitoring::smart_collector::is_available ( ) const -> bool

overridevirtual

Check if this plugin is available on the current system.

Returns

True if plugin can collect metrics, false otherwise

Availability checks may include:

• Platform compatibility (Linux-only, Windows-only)
• Hardware presence (GPU, sensors)
• Permission checks (root required)
• Resource availability (proc filesystem, WMI)

The registry may skip unavailable plugins during registration.

Implements kcenon::monitoring::collector_plugin.

is_healthy()

bool kcenon::monitoring::smart_collector::is_healthy

(

)

const

Check if collector is in a healthy state

Returns

True if collector is operational

is_smart_available()

bool kcenon::monitoring::smart_collector::is_smart_available

(

)

const

Check if SMART monitoring is available

Returns

True if smartctl is available

name()

auto kcenon::monitoring::smart_collector::name ( ) const -> std::string_view

inlineoverridevirtual

Get the unique name of this plugin.

Returns

Plugin name (must be unique within registry)

The name is used for:

• Plugin lookup and discovery
• Configuration mapping
• Metric tagging (added as "collector" tag)

Implements kcenon::monitoring::collector_plugin.
