Struct LoggingConfig 

pub struct LoggingConfig {
    pub level: String,
    pub tags: BTreeMap<String, String>,
    pub retention: Retention,
    pub alarm_segment_mb: u32,
}

Logging policy parsed from subc.jsonc.

retention is the rename-rotating policy for the daemon’s per-child stderr CAPTURE file (single writer). The daemon’s own log and every module’s log are date segments under fleet-logging r2, which never rotate; for those only retention.max_age_days applies, plus alarm_segment_mb.

Fields

level: String

tags: BTreeMap<String, String>

Per-logger levels. Keys are logger names; a key with no dot is taken as a COMPONENT of the module it is configured on (perf on synapse is synapse.perf), so an operator’s subc.jsonc reads naturally. See LoggingConfig::filter_spec.

retention: Retention

alarm_segment_mb: u32

Segment size at which the writer alarms (never truncates).

Implementations

impl LoggingConfig

pub fn filter_spec(&self, module_id: &str) -> String

The CK_LOG value for module_id. Logger names in CK_LOG are absolute (synapse.perf=info), while the config block is written per module, so a dotless key is prefixed with the module id here. A key that already starts with <module_id>. or contains a dot is passed verbatim; a key equal to the module id is the root and is also verbatim. Without this a config tags: { perf: debug } would emit perf=debug, which matches no logger on the r2 hierarchy and silently does nothing.

pub fn segment_retention(&self) -> SegmentRetention
