refresh_disk_monitored_datadir()

void hm::System_vars::refresh_disk_monitored_datadir ( MYSQL_THD  thd )

static

Read and store the global data directory for automatic path selection.

This runs during registration. Runtime updates request an asynchronous refresh through the collector settings path.

Parameters

[in]

thd

THD handle or nullptr for the global value

register_all()

int hm::System_vars::register_all ( )

static

void hm::System_vars::request_disk_monitored_datadir_refresh ( )

static

Request an automatic monitored path refresh after a system variable SET.

select_disk_monitored_path()

bool hm::System_vars::select_disk_monitored_path ( const std::string &  configured_path, std::string &  effective_path, uint64_t &  generation  )

static

Select the effective path monitored by the Disk Collector.

Parameters

[in]	configured_path	Configured disk_monitored value
[out]	effective_path	Configured path or stored data directory
[out]	generation	Current monitored-path cache generation

Returns

true if a usable effective path is available, false otherwise
