Member Function Documentation

◆ add_container_metrics()

void kcenon::monitoring::container_collector::add_container_metrics	(	std::vector< metric > &	metrics,
		const container_metrics &	container )

private

◆ collect()

auto kcenon::monitoring::container_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()

		double	value,
		const container_metrics &	container,
		const std::string &	unit = "" ) const

private

◆ get_last_metrics()

std::vector< container_metrics > kcenon::monitoring::container_collector::get_last_metrics ( ) const

Get last collected container metrics

Returns: Vector of container metrics

◆ get_metadata()

auto kcenon::monitoring::container_collector::get_metadata ( ) const -> plugin_metadata

inlineoverridevirtual

Get plugin metadata.

Returns: Metadata describing this plugin

Default implementation returns minimal metadata. Override to provide rich plugin information.

Reimplemented from kcenon::monitoring::collector_plugin.

Definition at line 172 of file container_collector.h.

Here is the call graph for this function:

◆ get_metric_types()

auto kcenon::monitoring::container_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()

auto kcenon::monitoring::container_collector::get_statistics ( ) const -> stats_map

overridevirtual

Get plugin statistics.

Returns: Map of statistic name to value

Optional: Override to provide plugin-specific statistics.

Reimplemented from kcenon::monitoring::collector_plugin.

◆ initialize()

auto kcenon::monitoring::container_collector::initialize ( const config_map & ) -> bool

overridevirtual

Initialize plugin with configuration.

Parameters

config Configuration key-value pairs

Returns: True if initialization succeeded

Called once after plugin registration. Optional: Default implementation always succeeds.

Reimplemented from kcenon::monitoring::collector_plugin.

◆ interval()

auto kcenon::monitoring::container_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 168 of file container_collector.h.

168{ return std::chrono::seconds(10); }

◆ is_available()

auto kcenon::monitoring::container_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_container_environment()

bool kcenon::monitoring::container_collector::is_container_environment ( ) const

Check if container metrics are available

Returns: True if running in a containerized environment

◆ name()

auto kcenon::monitoring::container_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.

Definition at line 166 of file container_collector.h.

166{ return "container"; }

container_collector & kcenon::monitoring::container_collector::operator= ( const container_collector & )

delete

◆ operator=() [2/2]

container_collector & kcenon::monitoring::container_collector::operator= ( container_collector && )

delete

◆ shutdown()

void kcenon::monitoring::container_collector::shutdown ( )

inlineoverridevirtual

Shutdown plugin and release resources.

Called before plugin destruction. Optional: Default implementation is no-op.
