kyleandClaude Opus 5.5 8d0e6dca71 Move code shared by the collectors into one module
The Veeam, MARS, WSB and VB365 collectors each carried identical copies
of logging, ISO time conversion, property lookup, posting to the API,
config loading, TLS setup, the sent-runs state file and the 401 check,
and their installers repeated the same key prompt, locked-down config,
file copy and scheduled-task registration. These now live in
collectors/common/BackupDashboard.Collector.psm1:

- Initialize-Collector / Test-RunSent / Send-JobReport /
  Test-AuthRejected / Complete-Collector for collector runs
- Write-Log, Get-ErrorText, ConvertTo-IsoTime, Get-FirstValue
- Install-CollectorTask for the shared half of each installer

Collectors find the module next to themselves (installed) or in
..\common (repo); installers copy it into Program Files beside the
collector. The diagnostic scripts stay standalone single files.

No behavior change: a harness ran each collector against its mock
(12 scenarios: dry run, two real runs against a stub API, state file,
logs, exit codes, rejected key, en-GB, backfill) before and after, and
all 84 outputs are identical. Installers, run with stand-ins for the
Windows-only commands, write identical configs and tasks; the only
differences are the module being copied and the summary line naming
the shell's path.

# Azure Backup (MARS agent) collector
A PowerShell script that runs on each server with the Microsoft Azure Recovery Services (MARS)
agent and reports its backups to the dashboard. Each server appears as one job,
named `<SERVER> - Azure Backup` by default.
> **Checked against:** MARS agent 2.0.9274, a Files & Folders policy with completed backups only.
> Not yet seen on a real agent: a failed backup, a backup in progress, or a System State policy.
> Those paths are written to the same object model, but if one looks wrong, run
> `Get-MarsCollectorDiagnostics.ps1` while it's in that state and send the output.
## Install (on the server, as an administrator)
Runs under Windows PowerShell 5.1 (`powershell.exe`), which the agent's `MSOnlineBackup` module
targets and which every supported Windows Server has.
1. On the dashboard host, create a key for this server:
```bash
python manage.py create-key mars-acme-fs01
```
2. Copy the whole `collectors` folder to the server (the installer needs `common`
as well as this folder), then from `collectors\mars` run:
```powershell
.\Install-MarsCollector.ps1 -ApiUrl https://backups.example.com -Tenant "Acme Corp"
```
Add `-JobName "File Server"` to choose the name shown on the dashboard. It prompts for the
key, then:
- writes `C:\ProgramData\BackupDashboard\mars-collector.json` (readable only by SYSTEM and Administrators)
- copies the script to `C:\Program Files\BackupDashboard\`
- registers the scheduled task **Backup Dashboard - MARS collector** (SYSTEM, every 60 minutes)
3. Preview the payloads, then backfill 30 days so the history view is populated straight away:
```powershell
powershell.exe -File 'C:\Program Files\BackupDashboard\Send-MarsBackupStatus.ps1' -DryRun
powershell.exe -File 'C:\Program Files\BackupDashboard\Send-MarsBackupStatus.ps1' -LookbackHours 720
```
It can be installed alongside the other collectors: it uses its own config, state, log and task.
Re-run the installer to change settings or update the script. It also installs
`BackupDashboard.Collector.psm1`, the code shared by all collectors, next to the script.
## What it sends
| Dashboard | MARS |
|---|---|
| Company | `Tenant` from the config |
| Job | One per server, ID `mars:<computer name>`, so changing `JobName` renames rather than duplicates it |
| Status | Backup job state: Failed → **Failed**. Completed with failed bytes or an error → **Warning**. Aborted/cancelled or unrecognised → **Warning**. In progress → **Running**. Restore jobs are ignored |
| Started / finished | Job start / end time. MARS reports these in UTC without marking them as UTC; the collector handles that |
| Next scheduled | Next slot from the backup policy schedule, or the System State policy's if that's sooner. Empty (so never Overdue) for schedules that run every 2+ weeks, since which week is next can't be told |
| Message | Job and per-datasource errors (non-zero error codes), failed file counts, and the failed-file log path |
| Size | Bytes transferred, summed across datasources |
Each run covers the last 48 hours (`LookbackHours`). Jobs already delivered are recorded in
`mars-collector.state.json`.
## Troubleshooting
- Log: `C:\ProgramData\BackupDashboard\mars-collector.log`. Exit codes: `0` OK, `1` some runs
failed to send (retried next run), `2` setup failed (config or MARS module).
- Wrong status, sizes or messages: run `.\Get-MarsCollectorDiagnostics.ps1` (read-only). It prints
the real structure of the objects the agent's cmdlets return.
## Testing without MARS
```powershell
. ./tests/MockMars.ps1
./Send-MarsBackupStatus.ps1 -ConfigPath ./my-test-config.json -DryRun
```
