Log limits

server.logLimits controls how many lines the API returns in the initial tail request that backs the log viewer. It sets the default value of the ?tail=N query parameter on /api/v1/logs/system and /api/v1/jobs/{name}/logs. Once the UI has the initial slice, it opens an SSE stream and appends every new line as it lands — there is no client-side cap.

This block does not size the on-disk log files. See Logs for path, rotation, and per-job/system toggles.

Options

Option	Type	Required	Default	Description
`jobLogs`	int	No	`10000`	Initial tail length per job log viewer.
`systemLogs`	int	No	`10000`	Initial tail length for the system log.

A client can request fewer lines with ?tail=N. Requests above 50,000 are clamped server-side so a single response never reads millions of lines off disk in one go.

Example

snapr.yaml

server:
  logLimits:
    jobLogs: 5000
    systemLogs: 20000

Edge cases

Setting either field to 0 falls back to the default (10,000). Use a small positive number to actually shrink the initial tail.
The hard server-side cap of 50,000 is independent of these defaults. Even an explicit ?tail=999999 is clamped to 50,000.
