ResourceMonitor

oxios_kernel::resource_monitor

Struct ResourceMonitor 

Source 
pub struct ResourceMonitor { /* private fields */ }
Expand description

Resource monitor collecting system and agent metrics.

Snapshots are automatically pushed to history when record_snapshot() is called. Use start_sampling() to spawn a background task that periodically records snapshots.

Implementations§

Source§

impl ResourceMonitor

Source

pub fn new(interval_secs: u64, history_max: usize) -> Self

Create a new monitor with the given sampling interval and history size.

Source

pub fn snapshot(&self) -> ResourceSnapshot

Take a snapshot of current resource usage.

Uses the shared sysinfo::System instance (refreshed on each call) instead of creating a new one each time.

Source

pub fn record_snapshot(&self)

Record a snapshot into the history buffer.

Call this to push the current metrics into the history ring buffer. Oldest entries are evicted when history_max is reached.

Source

pub fn start_sampling(self: &Arc<Self>) -> JoinHandle<()>

Spawn a background task that periodically records snapshots.

Returns a tokio::task::JoinHandle that can be aborted to stop sampling. Uses the interval_secs configured at construction time.

Source

pub fn history(&self, last_n: usize) -> Vec<ResourceSnapshot>

Returns historical snapshots, newest first.

Source

pub fn is_overloaded(&self) -> bool

Returns true if the system is currently overloaded.

Source

pub fn set_active_agents(&self, count: usize)

Update the active agent count.

Source

pub fn set_pending_tasks(&self, count: usize)

Update the pending tasks count.

Source

pub fn add_token_usage(&self, tokens: u64)

Add to the cumulative token usage counter.

Source

pub fn overload_threshold(&self) -> OverloadThreshold

Returns a copy of the current overload threshold.
