EXL SysTrack → Datadog Windows Integration

Powered by Zoos Global | EXL Service

_{Pipeline data source: SysTrack by Lakeside Software}

Python scripts → 73K+ endpoints → Datadog Logs → Dashboards & Alerts

❓ The Problem — Why This Exists

EXL relies on SysTrack for endpoint health, performance, and stability telemetry across its desktop fleet, but that data was trapped inside the SysTrack console with no path into the team’s central observability platform:

Massive scale, zero centralized visibility — Across 77,000+ endpoints, health scores, reboot status, application crashes, and application faults all lived only in SysTrack’s own UI, with no way to view or correlate them alongside the rest of EXL’s infrastructure and application monitoring in Datadog.
Critical signals buried in a console, not surfaced as alerts — Application crashes are a small but high-severity signal (only a handful of hosts), yet without active alerting they could go unnoticed for hours inside a console nobody was watching in real time.
No SLA or failure tracking for the data pipeline itself — Even if a collection process existed, there was no record of whether it ran successfully, how long it took, or whether it silently failed — making it impossible to trust the data without manual spot-checks.
No historical trending at scale — With tens of thousands of hosts, understanding fleet-wide health trends, reboot patterns, or fault frequency over time required exporting and manually analyzing data — not something that scales operationally.
High data volume with no safe ingestion path — At ~1.1GB/day across four data types, naively pushing this into a monitoring platform risked uncontrolled disk growth, log bloat, or ingestion failures without careful log rotation and file-based handling.
Windows-only environment constraint — Like other EXL on-prem services, the collection had to run natively on Windows Server using SYSTEM-level scheduled execution, ruling out Linux-native or service-based collection patterns.

✅ The Solution — What We Built

We built a stateless, Windows-native Python pipeline that pulls SysTrack data for all four key signal types and feeds it into Datadog through simple file-based log tailing — scaled to handle 77,000+ endpoints reliably every day.

Architecture

SysTrack Console / API
        ↓
  Python Collectors (4 scripts, stateless)
        ↓
  Structured JSON Log Files (rotating, 500MB × 5 backups per script)
        ↓
  Datadog Agent (file-tail log collection, wildcard rotation tracking)
        ↓
  Datadog Logs → Dashboards → Alerts

⚙️ System Requirements

Windows Server 2019+ / Windows 10+
Python 3.14+ (SYSTEM-WIDE)
Datadog Agent (Logs enabled)
PowerShell 5.1+
Admin/SYSTEM privileges for Task Scheduler

1️⃣ Install Python (CRITICAL)

Install Python for all users and add to SYSTEM PATH.

Download & Install

https://www.python.org/downloads/windows/
✅ Check "Add Python to PATH"
✅ Check "Install for all users"

Expected Path

C:\Program Files\Python314\python.exe

Verify Installation

where python
python --version
pip --version

Expected Output:

C:\Program Files\Python314\python.exe
Python 3.14.x
pip 24.x from C:\Program Files\Python314\Lib\site-packages\pip (python 3.14)

2️⃣ Install Python Dependencies

⚠️ Install as Administrator, using the full Python path with --no-user (see python-update.md for why: without it, packages install to your user profile, which the SYSTEM account running Task Scheduler cannot see).

"C:\Program Files\Python314\python.exe" -m pip install requests pandas openpyxl --no-user

Verify:

"C:\Program Files\Python314\python.exe" -c "import requests, pandas, openpyxl; print('requests', requests.__version__); print('pandas', pandas.__version__); print('openpyxl', openpyxl.__version__)"

Expected: requests 2.32+, pandas 2.3+, openpyxl 3.1+ (see offline_packages/requirements.txt for the full pinned list, including transitive dependencies like numpy)

5️⃣ Manual Script Validation (MANDATORY)

Before enabling schedulers, test each script manually:

cd C:\Scripts\exl_systrack\scripts

python sv_health_desktop.py
python sv_reboot_health.py
python sv_appcrash.py
python sv_appfault.py

Verify Success

dir ..\logs\apps\

(all app logs now use *.json.log except sv_process_queueLenth.json.log, whose filename intentionally keeps a typo – see section 8️⃣ for why)

Expected:

sv_health_desktop.json.log     ~80MB (67K hosts)
sv_reboot_health.json.log      ~8MB (8.7K hosts)
sv_appcrash.json.log           ~50KB (3 hosts)
sv_appfault.json.log           ~5MB (~1.2K hosts)

Check for Errors:

dir ..\logs\*_error.json.log

(directly under logs\, not a logs\errors\ subfolder – these are written locally but not currently tailed by Datadog; see section 8️⃣)

Should be empty or contain only API-related errors (401, timeout, etc.)

6️⃣ Windows Task Scheduler Setup

Each scheduler runs only PowerShell, never Python directly.

Production Schedule

Script	Interval	Priority	Offset	Daily Runs
`run_health.ps1`	4 hours (240 min)	Medium	00:00	6
`run_reboot.ps1`	30 minutes	High	00:00	48
`run_appcrash.ps1`	15 minutes	CRITICAL	00:00	96
`run_appfault.ps1`	30 minutes	High	00:05	48

Quick Setup (Command Line)

:: Health - Every 4 hours (240 minutes)
schtasks /create /tn "SysTrack-Health" /sc minute /mo 240 /st 00:00 /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_health.ps1" /ru SYSTEM /rl HIGHEST /f

:: Reboot - Every 30 minutes
schtasks /create /tn "SysTrack-Reboot" /sc minute /mo 30 /st 00:00 /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_reboot.ps1" /ru SYSTEM /rl HIGHEST /f

:: AppCrash - Every 15 minutes (CRITICAL)
schtasks /create /tn "SysTrack-AppCrash" /sc minute /mo 15 /st 00:00 /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_appcrash.ps1" /ru SYSTEM /rl HIGHEST /f

:: AppFault - Every 30 minutes (staggered +5min)
schtasks /create /tn "SysTrack-AppFault" /sc minute /mo 30 /st 00:05 /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_appfault.ps1" /ru SYSTEM /rl HIGHEST /f

Verify Tasks

schtasks /query /tn "SysTrack-*" /fo LIST /v

Expected Output:

TaskName:        \SysTrack-Health
Run As User:     NT AUTHORITY\SYSTEM
Task To Run:     powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_health.ps1
Schedule:        Every 240 minutes
Next Run Time:   <valid timestamp>

Register-ScheduledTask -TaskName "SysTrack-AppFault" -Action $action -Trigger $trigger -User "SYSTEM" -RunLevel Highest -Force

7️⃣ Execution Timeline ⏱️

00:00 → Health (4h) + Reboot (30m) + AppCrash (15m)
00:05 → AppFault (30m)
00:15 → AppCrash
00:30 → Reboot + AppCrash
00:35 → AppFault
00:45 → AppCrash

01:00 → Reboot + AppCrash
01:05 → AppFault
01:15 → AppCrash
01:30 → Reboot + AppCrash
...

04:00 → Health (4h) + Reboot + AppCrash
...

Daily Totals:
- Health:    6 runs  (00:00, 04:00, 08:00, 12:00, 16:00, 20:00)
- Reboot:   48 runs  (every 30 minutes)
- AppCrash: 96 runs  (every 15 minutes)
- AppFault: 48 runs  (every 30 minutes, +5min offset)

8️⃣ Datadog Agent Configuration

Location

C:\ProgramData\Datadog\conf.d\systrack.d\conf.yaml

⚠️ Must be named exactly conf.yaml (not conf.yml). The Datadog Agent’s config loader only recognizes conf.yaml / conf.yaml.example inside a check’s .d\ folder – a file named conf.yml is silently ignored, and none of these logs would ever reach Datadog even though everything else works.

Configuration

⚠️ This file is FROZEN in production. The live copy at the path above already has dashboards and monitors built on top of its exact paths, and it must never be edited to “fix” it – any change risks silently breaking those dashboards. The repo’s tracked copy at config\datadog\systrack.d\conf.yaml is a verbatim mirror of that live file (not an idealized/cleaned-up version), kept in version control for visibility only. It covers all 13 scripts.

Updated 2026-07-15 to match the current live file – production was corrected since the previous mirror, so the old lowercase/typo’d filenames below no longer apply. Two intentional quirks remain (not bugs to “fix”):

sv_health_desktop.json.log ships with source: sv_health (the short form, not the full script name) – cosmetic Datadog tag only.

sv_process_queueLenth.json.log / source: sv_process_queueLenth keeps the “Lenth” typo (missing “g”) even though the script itself is spelled correctly (sv_process_queueLength.py).

sv_appcrash and sv_appfault also use sources without the sv_ prefix (appcrash, appfault) – also cosmetic, no script-side impact.

There is currently no error-log glob and no history-log glob in the live file – error and history logs are written locally by scripts\*.py as before, but are not currently shipped to Datadog.

scripts\sv_process_queueLength.py has the one remaining DATADOG_LOG_FILENAME override (for the typo above). Run tools\systrack_conf_check.py any time either side changes to confirm scripts and conf.yaml still agree.

✅ Production Checklist

🚨 Conservative Start Schedule

If starting cautiously, use:

:: Health - Every 6 hours (360 minutes)
schtasks /create /tn "SysTrack-Health" /sc minute /mo 360 /st 00:00 /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_health.ps1" /ru SYSTEM /rl HIGHEST /f

:: Reboot - Every 1 hour (60 minutes)
schtasks /create /tn "SysTrack-Reboot" /sc minute /mo 60 /st 00:00 /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_reboot.ps1" /ru SYSTEM /rl HIGHEST /f

:: AppCrash - Every 30 minutes
schtasks /create /tn "SysTrack-AppCrash" /sc minute /mo 30 /st 00:00 /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_appcrash.ps1" /ru SYSTEM /rl HIGHEST /f

:: AppFault - Every 1 hour (60 minutes, +5min offset)
schtasks /create /tn "SysTrack-AppFault" /sc minute /mo 60 /st 00:05 /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\exl_systrack\schedulers\run_appfault.ps1" /ru SYSTEM /rl HIGHEST /f

Then increase frequency after 1-2 weeks of stable operation.
