## Account
|
||
|
||
**Scope:** Global (applies to this Sencho instance, not per-node)
|
||
|
||
Change the admin account password. All three fields are required.
|
||
|
||
| Field | Description |
|
||
|-------|-------------|
|
||
| **Current Password** | Your existing password for verification |
|
||
| **New Password** | Must be at least 6 characters |
|
||
| **Confirm New Password** | Must match New Password |
|
||
|
||
Click **Update Password** to apply. The change takes effect immediately; existing sessions remain valid.
|
||
|

|
||
|
||
## System Limits
|
||
|
||
**Scope:** Per-node (applies to the currently selected node)
|
||
|
||
Configure resource thresholds that trigger visual warnings on the dashboard stat cards. These are display thresholds only — Sencho does not throttle or kill containers when limits are reached.
|
||
|
||
| Setting | Range | Description |
|
||
|---------|-------|-------------|
|
||
| **Host CPU Limit** | 1–100% | CPU percentage above which the CPU card turns orange/red |
|
||
| **Host RAM Limit** | 1–100% | RAM percentage above which the RAM card turns orange/red |
|
||
| **Host Disk Limit** | 1–100% | Disk percentage above which the Disk card turns orange/red |
|
||
| **Docker Janitor Threshold** | ≥ 0 GB | Minimum free disk space to maintain. When free space falls below this value, a warning is shown. Set to `0` to disable. |
|
||
| **Global Crash Alerts** | On / Off | When enabled, Sencho sends a notification whenever any managed container exits unexpectedly |
|
||
|
||
Click **Save** to apply. An unsaved-changes indicator appears when you have edits pending.
|
||
|

|
||
|
||
## Notifications
|
||
|
||
**Scope:** Global
|
||
|
||
Configure external destinations for alert notifications. Three agent types are supported, each on its own sub-tab: **Discord**, **Slack**, and **Webhook**.
|
||
|
||
For each agent:
|
||
|
||
| Field | Description |
|
||
|-------|-------------|
|
||
| **Enable toggle** | Activates or deactivates this agent. Disabled agents receive no messages even if a URL is saved. |
|
||
| **Webhook URL** | The endpoint Sencho will POST to when an alert fires |
|
||
|
||
Click **Save** to persist changes. Click **Test** to send a test payload immediately and verify delivery.
|
||
|
||
At least one agent must be enabled for stack alerts to deliver notifications. See [Alerts & Notifications](/features/alerts-notifications) for how to create alert rules.
|
||

|
||
|
||
## Appearance
|
||
|
||
**Scope:** Global (stored in the browser, not the server)
|
||
|
||
| Setting | Options | Description |
|
||
|---------|---------|-------------|
|
||
| **Theme** | Light / Dark / Auto | `Auto` follows the OS system preference. Changes apply immediately without a page reload. |
|
||
|
||
---
|
||
|
||
## Developer
|
||
|
||
**Scope:** Per-node (applies to the currently selected node)
|
||
|
||
Advanced settings for log streaming behaviour and data retention. Most users can leave these at their defaults.
|
||
|
||
| Setting | Default | Description |
|
||
|---------|---------|-------------|
|
||
| **Developer Mode** | Off | When on, the [Global Observability](/features/global-observability) view switches from polling to real-time Server-Sent Events streaming |
|
||
| **Global Logs Refresh Rate** | 5s | Polling interval in standard mode. Options: `1s`, `3s`, `5s`, `10s` |
|
||
| **Metrics Retention Hours** | 24 | How many hours of CPU/RAM history to keep for dashboard charts. Max: 8,760 (1 year) |
|
||
| **Log Retention Days** | 30 | How many days of notification history to keep in the database. Max: 365 |
|
||
|
||
Click **Save** to apply.
|
||
|
||
<Note>
|
||
Lower refresh rates (1s) increase backend CPU usage as Sencho polls Docker more frequently. Use only when actively debugging.
|
||
</Note>
|

||
## Nodes
|
||
|
||
**Scope:** Global
|
||
|
||
Manage connections to local and remote Sencho instances. This is the same interface as the [Multi-Node](/features/multi-node) feature — see that page for the full walkthrough.
|
||
|
||

## App Store
|
||
|
||
**Scope:** Global
|
||
|
||
| Setting | Default | Description |
|
||
|---------|---------|-------------|
|
||
| **Template Registry URL** | LinuxServer.io registry | The URL Sencho fetches templates from. Must return a JSON array in Portainer v2 template format. Leave blank to restore the default. |
|
||
|
||
Click **Save** to update the URL. Click **Refresh Cache** to clear the cached template list and fetch fresh data from the registry immediately.
|
||

||
See [App Store](/features/app-store#custom-template-registry) for more on custom registries.
