Settings read-only

Display Timezone

Controls how all dashboard timestamps render. Stored server-side under {dataDir}/display_timezone.json. Three-tier resolution: this setting (if set) → browser auto (if blank). Applies to every authenticated session.

IANA timezone:

Other SynthIqConfig values from appsettings.json below are read-only. Edit-capability for the rest is Phase 2 (RI-2026-084, post-conference). For now, edit appsettings.Production.json on the host and restart the service.

Authentication

Session lifetime + account lockout policy. SynthIQ always requires login; toggling auth off is a deploy-time appsettings.json concern, not an operator-runtime control. LDAP/AD accounts follow Active Directory Group Policy and are not affected by the Max Login Attempts setting (Phase 3 will add the LDAP card).

Session Duration (hours)

How long a login session stays active without activity. 1..720 (30 days max).

Max Login Attempts

Consecutive failed logins before lockout. 0 disables lockout. Default: 5.

Disk Space Monitor

Enable disk space monitoring (master toggle for all configured drives)

Configure up to 10 drive paths to monitor independently. Each drive has its own alert threshold and enable toggle. Drives not listed here use the default threshold below; the Analytics > Disk Usage chart's alert line follows the per-drive value.

Default Alert Threshold (%): applied to any enumerated drive that doesn't have a per-drive override below

Disk Watermark Auto-Purge

Enable preventive auto-purge when the data drive exceeds the watermark

When the data drive's used space exceeds the watermark, SynthIQ purges oldest rows from the analytics + affinity stores in the priority order below until usage drops to watermark − 5%. Independent of the standing 30-day analytics retention; both can run.

Watermark (% used)

Live data-drive usage

Reading /api/analytics/disk_usage…

Purge Priority (one entry per line, top-to-bottom order)

Allowed: analytics_disk_snapshots, analytics_routing_events, affinity_expired_bindings, log_files_oldest. SynthIQ has no at-rest DICOM blobs (three-property invariant); only metadata stores get pruned.

Notify on

Backend unhealthy — pool-Router transitions from healthy to unhealthy Storage Commit timeout — pending N-EVENT-REPORT exceeds horizon Disk watermark crossed — data drive used % exceeds threshold Affinity sweep failure — purge of expired affinity bindings threw

LDAP / Active Directory

Enable LDAP / AD authentication

When enabled, the login flow tries the local SynthIQ user store first; on miss, it falls through to LDAP/AD. Test Bind is on the Roles & LDAP page.

Use SSL (LDAPS, port 636) Use StartTLS

Bind DN Template

If set, login does a direct bind using {username} substitution. Leave blank to use service-account search-then-bind.
