pub struct MetricsDb { /* private fields */ }

Expand description

Metrics database, useful for querying stored metrics

Implementations

source

impl MetricsDb

source

pub fn new<P: AsRef<Path>>(path: P) -> Result<Self>

Creates a new metrics DB with given path of a SQLite database

source

pub fn sessions(&self) -> &[Session ]

Returns sessions in database, based on SESSION_TIME_GAP_THRESHOLD

source

pub fn available_keys(&self) -> Result<Vec<String>>

Returns list of metrics keys stored in the database

source

pub fn metrics_for_key(
 &self,
 key_name: &str,
 session: Option<&Session>
) -> Result<Vec<Metric>>

Returns all metrics for given key in ascending timestamp order

source

pub fn deriv_metrics_for_key(
 &self,
 key_name: &str,
 session: Option<&Session>
) -> Result<Vec<DerivMetric>>

Returns rate of change, the derivative, of the given metrics key’s values

f(t) = (x(t + 1) - x(t)) / ((t+1) - (t)
