Cascades — CHEF-PC Slow Diagnosis + MDIRECTOR-PC RAM Plan

Session Summary

Howard inquired about upgrading the RAM on two workstations, MDIRECTOR-PC and CHEF-PC, both Acer Aspire C24-865 AIOs with Intel i5-8250U CPUs. After reviewing documentation and confirming hardware specifications, it was determined that MDIRECTOR-PC required a 2x 4GB DDR4-2400 SODIMM upgrade, while CHEF-PC already had 12 GB and would not benefit from an 8 GB upgrade. Howard then shifted focus to CHEF-PC, which was experiencing performance issues. An audit of the GuruRMM enrollment revealed that CONTEXT.md was outdated, with 30 agents enrolled, not two. CHEF-PC was confirmed enrolled with agent ID a2cedfea-8239-4cab-bff7-54d99c417ed1. Remote diagnostics identified storage subsystem saturation due to concurrent agent activity. Five agent stacks were running simultaneously, including Datto RMM, Syncro RMM, GuruRMM, Datto AV, and Infocyte EDR, all contributing to high CPU and storage load. The workstation also had asymmetric RAM and a Patriot P210 SSD with partition and performance issues.

Key Decisions

  • RAM upgrade only on MDIRECTOR-PC. CHEF-PC already had 12 GB, making an 8 GB upgrade a downgrade.
  • Prioritize matched DDR4-2400 SODIMM pair for MDIRECTOR-PC. Ensures dual-channel performance for the iGPU.
  • Remote diagnostics first, no changes. Avoided unnecessary onsite work by identifying the root cause of CHEF-PC's slowness through API and PowerShell commands. Per Howard's instruction, no remediation was applied.
  • Keep ScreenConnect, plan removal of other remote tools. Maintained ACG standard while flagging non-essential tools for removal.
  • Defer SSD replacement. Postponed until after agent cleanup to avoid premature hardware replacement.

Problems Encountered

  • Outdated CONTEXT.md. Listed only 2 enrolled agents at Cascades; actual count is ~30 (enrolled 2026-04-18). Resolved by cross-referencing the GuruRMM admin API directly.
  • Concurrency of agent stacks. Five RMM/EDR agents caused storage and WMI subsystem saturation. Identified the stacks and provided a removal sequence for onsite work.
  • Asymmetric RAM configuration. Split 8 GB + 4 GB modules cause effectively single-channel access for the upper 4 GB band. Documented as secondary issue.
  • Patriot P210 SSD limitations. Known SLC-cache exhaustion under sustained writes plus partition geometry (only half the disk allocated). Recommended C: partition extension; SSD replacement deferred.
  • Get-StorageReliabilityCounter hang during diagnostics. Cmdlet ran for 75+ s while a parallel trivial PowerShell command round-tripped in 4 s on the same agent. Switched to Win32_DiskDrive + Get-PhysicalDisk (without reliability counter) to gather hardware data. The hang itself is diagnostic evidence of storage-stack saturation.

Configuration Changes

None. Read-only diagnostics only on CHEF-PC. No remediation performed.

Credentials & Secrets

  • GuruRMM dashboard admin: admin@azcomputerguru.com / GuruRMM2025 — vault projects/gururmm/dashboard.sops.yaml
  • GuruRMM JWT issued during this session (~24h life): see vault for canonical credential, do not paste tokens to logs

Infrastructure & Servers

GuruRMM

  • API (external): https://rmm-api.azcomputerguru.com
  • API (internal): http://172.16.3.30:3001
  • Dashboard: https://rmm.azcomputerguru.com
  • POST endpoint for remote command execution: POST /api/agents/{agent_id}/command with body {"command":"<script>","command_type":"powershell"} — note the field is command, NOT command_text (latter is the GET response field). Schema validation returns 422 if you use the wrong field name.
  • GET command result: GET /api/commands/{command_id} — returns status, exit_code, stdout, stderr, started_at, completed_at.
  • command_type accepts powershell or shell.

clients/cascades-tucson/CONTEXT.md "Agents currently enrolled" table needs updating — currently lists only DLTAGOI and CS-SERVER.

Pending / Incomplete Tasks

MDIRECTOR-PC (Howard buying parts)

  • Order 2x 4GB DDR4-2400 SODIMM 260-pin 1.2V (Crucial CT4G4SFS824A, Kingston KVR24S17S6/4, or kit Crucial CT2K4G4SFS824A)
  • Onsite RAM swap (replace existing 1x 4GB with matched 2x 4GB pair for dual-channel)
  • Verify with Get-CimInstance Win32_PhysicalMemory post-swap
  • Uninstall disabled COMODO Antivirus
  • Plan Win 11 Home -> Pro upgrade (so it can domain-join)
  • Remove old user profile Anna Pitzlin (last login 2025-06-26)

CHEF-PC (onsite remediation, deferred)

  • Confirm with Mike that GuruRMM is canonical RMM going forward at Cascades
  • Uninstall in order, reboot between each: Syncro stack -> Datto RMM -> Infocyte / Datto EDR -> Datto AV (verify Defender first) -> Splashtop -> Norton Security Scan
  • Confirm Dropbox usage with chef Ramon Castaneda / Michael Sabia before removing
  • Extend C: partition to consume the unallocated ~254 GB (use Resize-Partition -DriveLetter C -Size <max>)
  • Optional: rebalance RAM to matched 2x 8GB or 2x 4GB for full dual-channel
  • Re-test after cleanup; if still slow, plan Samsung 870 EVO 500GB or WD Blue SA510 clone-and-swap (P210 is junk-tier)
  • Disable RDP (audit notes it's enabled with NLA — not needed on a chef workstation)
  • Enable BitLocker
  • Enable screen lock policy

Fleet-wide (flag for Mike)

  • Previous-MSP cruft cleanup is not unique to CHEF-PC — every Cascades workstation onboarded into GuruRMM since 2026-04-18 likely still has Datto RMM + Syncro + Infocyte + Splashtop running. This is a fleet cleanup project, not a one-machine fix. Strategy + ordering decision needed.

Documentation

  • Update clients/cascades-tucson/CONTEXT.md "Agents currently enrolled" section. Current text says 2 agents (DLTAGOI, CS-SERVER); reality is ~30 since 2026-04-18.

Note for Mike

Fleet-wide MSP cleanup decision needed. Every Cascades workstation we onboarded into GuruRMM since 2026-04-18 still has the previous MSP's Datto RMM, Datto AV, Datto EDR (Infocyte), Syncro RMM, and Splashtop running concurrently with our agent. CHEF-PC is the visible symptom — five RMM/EDR stacks plus three remote-access tools running simultaneously, with SyncroLive.Agent.Runner alone consuming 35+ minutes of CPU time and WmiPrvSE saturated. Before I scrip a fleet uninstall, need confirmation: (1) is GuruRMM the canonical RMM going forward? (2) Datto AV out, Defender in? (3) Are we still under contract on any of the Datto/Syncro tooling we'd be ripping out? Will scope this onsite workstation by workstation, but the fix is fleet-wide, not just CHEF-PC.
