- Validate resolved IPs immediately before connecting.
- Guard Shoutrrr requests during initialization and delivery.
- Require admins for services without HTTP client support.
- Test DNS rebinding, redirects, internal hosts, and authorization.
Add a new "ContainerHealth" alert type that fires when a Docker container's
health check reports unhealthy, and resolves when it recovers. This mirrors
the existing Status (up/down) alert pattern: an alert can be armed per system
and honors the "min minutes" delay before firing.
When the alert fires, the notification (email and any configured webhook,
including Discord via shoutrrr) includes a log excerpt fetched live from the
agent for up to 2 of the unhealthy containers, prioritizing lines containing
"error" or "fatal" (falling back to the log tail if none match), capped to
keep the message well under Discord's size limit.

Adds a user-configurable "Failed Services" alert that notifies when any
tracked systemd service enters the failed state, and again when all services
recover.

createSessionWithTimeout checked sys.client for nil and then dereferenced
it again inside the goroutine that calls NewSession. update() runs the
SMART fetch in its own goroutine, so closeSSHConnection can clear the
field between those two reads and the goroutine dereferences a nil
client, panicking the whole hub process.
Make client an atomic.Pointer, load it once before starting the
goroutine, and clear it with Swap so a concurrent close cannot be
observed mid-session-creation. NewSession on an already-closed client
returns an error, which the existing retry path already handles.
Closes#2157
- Report battery data for individual devices
- Select a representative battery for legacy fields and alerts
- Average named battery data independently
- Display multiple batteries in system charts
- Add cross-platform coverage and transport tests
intel_gpu_top does not support the xe driver, so skip it for xe devices
and let the existing nvtop last-resort collector handle them. nvtop leaves
device_name unset on xe, so name the GPU from its PCI device id ("Intel GPU
(<id>)"). Adds nvtop to the Intel agent image (gputop already ships with
igt-gpu-tools).
