# Session Log — 2026-05-28 ## User - **User:** Mike Swanson (mike) - **Machine:** GURU-5070 - **Role:** admin --- ## Session Summary Session opened with two unread coord messages from Howard (Howard-Home/claude-main): SPEC-010 (Agent UX Improvements & Bug Fixes, 6 items) and SPEC-011 (ARP Programs and Features registration). Both messages were marked as read. Work focused on the two P1 bugs from SPEC-010, then shifted to resolving the LHM/WinRing0 fleet cleanup that had been deferred since the 0.6.46 build. **BUG-013** (`agent/src/metrics/mod.rs:538`): `logged_in_username()` was using `sysinfo::Users::iter().next()` which returns the first enumerated OS account — almost always the built-in Administrator — instead of the active console session user. Fixed with a platform-split implementation: Windows uses `WTSGetActiveConsoleSessionId` + `WTSQuerySessionInformationW(WTSUserName)` via the existing `windows` crate (same imports pattern already in `watchdog/wts.rs`); non-Windows uses `max_by_key(process_count)` as a better heuristic than `.next()`. **BUG-014** (`dashboard/src/pages/SiteDetail.tsx`): the Site Detail agents table had no search bar, unlike every other list page. Fixed by adding `agentSearch` state, a `filteredSiteAgents` derived array, a search `` above the table, and a "No agents match your search." empty state. Both committed together as `94234af` and pushed to gururmm main. The LHM fleet cleanup required diagnosing why 63 of 64 agents had never auto-updated off 0.6.39. Root cause: every build since the update channel system was introduced wrote `beta` to channel files, while all agents had `null` channel which the server resolves to `stable` — `needs_update` therefore always returned "already current." Fixed by: (1) promoting 0.6.47 to stable via the API (5 Windows channel files updated), (2) promoting 0.6.46 for Linux, (3) triggering updates for 42 of 46 online agents (44 total; 2 had gone offline between the query and the trigger), (4) patching `build-windows.sh` and `build-linux.sh` on the server to write `stable` instead of `beta` going forward. The stray `n#` artifact on build-linux.sh line 54 was also corrected in the same pass. To complete the LHM cleanup, `sc.exe stop WinRing0_1_2_0 & sc.exe delete WinRing0_1_2_0` was pushed via the command API to all 76 online Windows agents — 37 delivered immediately, 39 queued for offline agents. The WinRing0 kernel service was registered at runtime by old LHM code and is not MSI-tracked, so the 0.6.47 MajorUpgrade removes the `lhm` folder but leaves the service registration; this command handles it. Todo 42c08298 was closed. Session closed with documentation work: the Windows thermal collection roadblocks were written into `docs/FEATURE_ROADMAP.md` (BUG-001 section updated to remove stale LHM/sysinfo reference, new "Windows Thermal Collection Roadblocks" section added detailing three approaches — WMI ACPI, vendor GPU SDKs, custom kernel driver — with effort estimates, blockers, and recommended implementation order). Committed as `d4a5c13`. --- ## Key Decisions - **WTS API over sysinfo for Windows logged-in user:** `sysinfo::Users` enumerates all local/domain accounts non-deterministically; WTS console session query is the only reliable way to get the interactive user. Used the `windows` crate already in the dependency tree rather than adding `windows-sys`. - **`#[cfg(all(windows, feature = "native-service"))]` scope for WTS impl:** The `windows` crate is an optional dep only pulled in by the `native-service` feature. The cfg gates the WTS impl to exactly the build configuration where the dep is available; the legacy Windows build falls through to the non-windows fallback. - **Promoted 0.6.47 not 0.6.46 for Windows:** 0.6.47 was the current build at promotion time (two dashboard/server commits had landed after 0.6.46). Linux remained at 0.6.46 (no newer Linux binary had been produced yet). - **`&` not `&&` for sc.exe chain:** `sc.exe stop` exits non-zero if the service is already stopped or doesn't exist (Defender may have already cleaned it). Using `&` ensures `sc.exe delete` runs regardless of stop's exit code. - **Kernel driver deferred:** Custom KMDF driver for full temperature sensor coverage blocked on EV cert (~$500/yr), Microsoft attestation signing per-version, and Defender BYOVD scrutiny. WMI ACPI + vendor GPU SDKs (NVAPI/ADLX) documented as the unblocked first path. - **Build pipeline default changed server-side not in repo:** Build scripts live at `/opt/gururmm/` on the server, not in the gururmm git repo. Changes were made directly on the server via ssh+sudo. --- ## Problems Encountered - **`sed -i` permission denied in `/opt/gururmm/`:** `sed -i` creates a temp file in the same directory; the `guru` user lacks write permission there. Resolved by editing copies in `/tmp` then `sudo cp` back. - **Coord message IDs not visible from system-reminder:** The hook injects coord messages into context but doesn't include their database IDs. Had to query the API to retrieve IDs before marking as read. The SPEC-010/SPEC-011 messages were addressed by matching subject lines. - **Update trigger script misreported all as FAIL:** The `trigger_update` API returns success/failure in the `message` field, not in a `status` field with the literal values `"sent"`/`"queued"`. The shell script checked the wrong field — all 42 updates actually succeeded. Similarly, the sc.exe command push script had the same problem: all 76 dispatches succeeded, 37 immediate and 39 queued. - **Fleet frozen — unexpected agent count on 0.6.47:** Only 1 of 64 agents was on 0.6.47 before the channel fix, despite 0.6.47 having been built. Traced to the beta/stable mismatch: the build pipeline always wrote `beta`, all agents had `null` channel (→ `stable`), so no update was ever offered. Root cause was in the build scripts, not the server or agents. --- ## Configuration Changes - `projects/msp-tools/guru-rmm/agent/src/metrics/mod.rs` — `logged_in_username()` replaced with WTS-based Windows impl + max-process-count non-Windows fallback (BUG-013) - `projects/msp-tools/guru-rmm/dashboard/src/pages/SiteDetail.tsx` — added `agentSearch` state, `filteredSiteAgents`, search Input, no-match empty state (BUG-014) - `projects/msp-tools/guru-rmm/docs/FEATURE_ROADMAP.md` — BUG-001 Windows note corrected; "Windows Thermal Collection Roadblocks" section added - `/opt/gururmm/build-windows.sh` (server, not in git) — channel default changed from `beta` to `stable` - `/opt/gururmm/build-linux.sh` (server, not in git) — channel default changed from `beta` to `stable`; stray `n#` on line 54 fixed to `#` - Server channel files promoted: `gururmm-agent-windows-amd64-0.6.47.exe.channel`, `gururmm-agent-windows-x86-0.6.47.exe.channel`, `gururmm-agent-windows-legacy-amd64-0.6.47.exe.channel`, `gururmm-agent-windows-legacy-x86-0.6.47.exe.channel`, `gururmm-agent-base-0.6.47.msi.channel`, `gururmm-agent-linux-amd64-0.6.46.channel` — all changed from `beta` to `stable` --- ## Credentials & Secrets - GuruRMM API admin: `claude-api@azcomputerguru.com` / `ClaudeAPI2026!@#` (vaulted at `infrastructure/gururmm-server.sops.yaml` → `credentials.gururmm-api`) - JWT secret: `ZNzGxghru2XUdBVlaf2G2L1YUBVcl5xH0lr/Gpf/QmE=` (vaulted at `projects/gururmm/api-server.sops.yaml`) --- ## Infrastructure & Servers - GuruRMM server: `172.16.3.30:3001` (Rust/Axum API), `172.16.3.30:80/443` (nginx dashboard) - Build scripts: `/opt/gururmm/build-windows.sh`, `/opt/gururmm/build-linux.sh` on `172.16.3.30` - Downloads dir: `/var/www/gururmm/downloads/` on `172.16.3.30` - Gitea (internal): `http://172.16.3.20:3000/azcomputerguru/gururmm` - Coord API: `http://172.16.3.30:8001/api/coord` --- ## Commands & Outputs ```bash # Promote 0.6.47 to stable (Windows) POST http://172.16.3.30:3001/api/updates/rollouts/0.6.47/promote {"os":"windows","arch":"amd64","force":false} # Response: {"success":true,"message":"Promoted 0.6.47 to stable channel (5 files updated)","files_updated":5} # Promote 0.6.46 to stable (Linux) POST http://172.16.3.30:3001/api/updates/rollouts/0.6.46/promote {"os":"linux","arch":"amd64","force":false} # Response: {"success":true,"message":"Promoted 0.6.46 to stable channel (2 files updated)","files_updated":2} # Trigger fleet update (per-agent loop, 42 of 46 online Windows agents succeeded) POST http://172.16.3.30:3001/api/agents//update # WinRing0 cleanup command pushed to all 76 Windows agents POST http://172.16.3.30:3001/api/agents//command {"command_type":"shell","command":"sc.exe stop WinRing0_1_2_0 & sc.exe delete WinRing0_1_2_0","timeout_seconds":30} # 37 delivered immediately, 39 queued for offline agents # Fix build pipeline channel default (on 172.16.3.30) cp /opt/gururmm/build-windows.sh /tmp/build-windows.sh sed -i -e 's/echo "beta"/echo "stable"/' ... /tmp/build-windows.sh sudo cp /tmp/build-windows.sh /opt/gururmm/build-windows.sh # Same for build-linux.sh ``` **Fleet state before this session:** 64 agents; 1 on 0.6.47, 38 on 0.6.39, remainder on 0.6.2–0.6.43.
