refreshSystemDetails() takes NCPU and MemTotal from the Docker daemon's
/info response. That only describes this machine when the daemon shares its
kernel. On macOS and Windows Docker runs inside a Linux VM, so the system
details header shows the VM's memory as the host total, and the VM's CPU
count clamps both cores and threads through the lxc branch below it.
Only consult Docker's host info on platforms where the daemon runs natively.
Everything else already falls back to gopsutil, which reads this host.
SwapCached pages have been read back into memory but still occupy allocated swap slots. Subtracting them from SwapTotal - SwapFree underreported swap usage compared with free, Glances, and gopsutil's canonical SwapMemory metric.
Every other metric in getSystemStats is stored through utils.TwoDecimals.
The load averages were assigned straight from gopsutil, so whatever the
platform reported was recorded verbatim.
On Linux that goes unnoticed because /proc/loadavg is already two decimal
places. Everywhere else it is not. macOS and BSD divide a fixed point
value by fscale and produce numbers like 2.55322265625, and the Windows
implementation synthesises the average as a decaying EWMA over the
processor queue length counter, so an idle machine reports values like
1.3667392689044936e-73 instead of 0.
The hub already treats two decimals as the canonical precision for this
field, since records.go rounds the load average when it averages records.
That left the raw agent records as the only place carrying full precision.
gopsutil's host.Uptime() calls the sysinfo(2) syscall. Inside an LXC
container lxcfs virtualizes /proc/uptime but cannot intercept a
syscall, so every container reported the host's uptime.
Reads /proc/uptime on linux and falls back to host.Uptime() if the file
is missing or unparseable, so other platforms are unchanged.
gopsutil's cpu.Info() does not parse the 'cpu model' field from
/proc/cpuinfo, which is the only source of CPU model names on MIPS.
Add a fallback that reads /proc/cpuinfo directly and combines
'cpu model' (e.g. 'MIPS 1004Kc V2.15') with 'system type'
(e.g. 'MediaTek MT7621 ver:1 eco:3') for a complete identifier.
The fallback only triggers when gopsutil returns an empty ModelName,
so x86/ARM/other architectures are unaffected.
- 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
Extract host memory derivation into calculateHostMemoryUsage and use
saturating subtraction to prevent uint64 underflow caused by race
conditions when reading /proc/meminfo. Also ensure UsedPercent guards
against division by zero.

- add includedetails flag to data requests for better efficiency
- integrate docker host info api for better os detection
- pull more OS details as well as cpu arch
- separate info bar component and refactor for new info
Implement battery error reporting mechanism
Added error reporting for battery information retrieval.
Handles cases like bluetooth devices where `battery` finds it but it has incomplete information about that battery, which would have otherwise caused a null pointer error.
