Validating Production Connectivity Before Enabling Schedules

4 min read
On this page

In this lesson, you will learn:

  • Why test again in production
  • What to test
  • Keeping schedules off until green

🔁 Quick look back: Last time: Setting Up Production MID Servers and Secure Credentials. You learned how production MID Servers and credentials were set up.

1 The Problem: Production Paths Aren’t the Same as Test Paths

snwrtest used one MID Server. snwr uses four, in different places. So:

  • Some firewall rules are new.
  • Some paths have never been tested.

🎯 The problem: Production paths aren’t the same as test paths.

👉 The fix: Rerun the connectivity and DNS checks from each production MID Server, with schedules still off.

Table of production checks.
Figure 1. Production connectivity checks.

2 What to test

  • Every port matrix row, from the production MID Server.
  • DNS forward and reverse.
  • Outbound HTTPS to snwr.
  • Agent connections from Finance.

3 Schedules stay off

⭐ Remember: Don’t activate a schedule until every check for its zone is green.

4 Project Clear View: How We Implemented It

📍 Situation: Production MID Servers were ready.

🧭 Decision: Test every path before switching on schedules.

🛠️ Steps we took:

  1. Reran the connectivity tests from each production MID.
  2. Reran DNS checks.
  3. Checked Finance agents could reach the Mumbai cluster.
  4. Kept all schedules inactive.

✅ What we verified:

  • Every row is green.
  • No schedule was active during testing.

📁 Evidence: Production connectivity log.

5 Quick recap

  • Production paths differ from test.
  • Retest ports, DNS, HTTPS and agent connections.
  • Keep schedules off until green.
  • Record the results.

6 Check yourself

Think of your answer first. Then tap to check.

1 Why retest in production? Show answer

Production uses different MID Servers and new firewall rules.

2 When can a schedule be activated? Show answer

Only after every check for its zone is green.

3 What did you check for Finance? Show answer

That agents could reach the Mumbai cluster.

Nice work! Production paths are proven. 🎉
