Didactum Monitoring & Netmon 7 Integration

Complete step-by-step guide for integrating Didactum Monitoring devices and sensors into Netmon 7 via SNMP – including device discovery, SNMP Credential Store, Performance Tracker, OID polling, alert configuration and email notification.

Product Note: Netmon 7 is a complete network monitoring system with support for SNMPv1, v2c and v3. For Didactum environmental sensors, two integration approaches are relevant: Performance Tracker (query and visualize custom OIDs as metrics) and Alert Configuration (report threshold violations via email). In addition, Netmon 7 offers a built-in SNMP-Walk for OID determination. This guide fully covers both variants.

Software: Netmon 7.x
Protocol: SNMP v1 / v2c / v3
Devices: Didactum Monitoring System 100T / 300G / 500G / 550T

5. Execute SNMP Walk in Netmon 7 (Determine Sensor IDs)

Netmon 7 provides a built-in SNMP-Walk tool. This allows you to determine all available OIDs of the Didactum device without external tools.

Netmon 7 → Device Dashboard → Select device "Didactum Server Room"
→ Tools → SNMP Walk
  Enter OID: .1.3.6.1.4.1.46501.5.1.1
  Community: didactum_netmon
  Version: v2c
→ Start Walk

The result list shows all sensor names (.5), status values (.6) and measurement values (.7) with their sensor IDs. These IDs are required in the following steps.

6. OID Reference for Didactum Sensors

All Didactum OIDs start with .1.3.6.1.4.1.46501. The sensor ID is appended at the end.

OID fields per sensor

Field	Meaning	Example OID
.5.x.SENSOR_ID	Sensor Name (String)	.1.3.6.1.4.1.46501.5.1.1.5.101001
.6.x.SENSOR_ID	Status: 0=Normal, 1=Warning, 2=Critical, 3=Error	.1.3.6.1.4.1.46501.5.1.1.6.101001
.7.x.SENSOR_ID	Measurement value (current)	.1.3.6.1.4.1.46501.5.1.1.7.101001

Sensor types with OIDs and Netmon thresholds

Sensor Type	Sensor ID	OID Measurement Value	Scaling	Recommended Threshold
Temperature Sensor Port 1	101001	.1.3.6.1.4.1.46501.5.1.1.7.101001	Raw value ÷ 10 = °C	Warning: 28 °C / Critical: 35 °C
Temperature Sensor Port 2	101002	.1.3.6.1.4.1.46501.5.1.1.7.101002	Raw value ÷ 10 = °C	Warning: 28 °C / Critical: 35 °C
Humidity Sensor Port 1	102001	.1.3.6.1.4.1.46501.5.1.1.7.102001	Direct value = %rH	Warning: 80 % / Critical: 90 %
Combined Sensor Temperature (CAN)	103001	.1.3.6.1.4.1.46501.5.1.1.7.103001	Raw value ÷ 10 = °C	Warning: 28 °C / Critical: 35 °C
Combined Sensor Humidity (CAN)	103002	.1.3.6.1.4.1.46501.5.1.1.7.103002	Direct value = %rH	Warning: 80 % / Critical: 90 %
Door Contact	104001	.1.3.6.1.4.1.46501.5.1.1.7.104001	0 = closed, 1 = open	Warning: from value 1
Smoke Detector	106001	.1.3.6.1.4.1.46501.5.1.1.7.106001	0 = OK, 1 = Alarm	Critical: from value 1
Water Sensor / Leakage (Spot)	107001	.1.3.6.1.4.1.46501.5.1.1.7.107001	0 = dry, 1 = water detected	Critical: from value 1
Water Sensor / Leakage (Cable)	107002	.1.3.6.1.4.1.46501.5.1.1.7.107002	0 = dry, 1 = water detected	Critical: from value 1
System Status (Device overall)	–	.1.3.6.1.4.1.46501.1.1.0	0 = OK, 1 = Warning, 2 = Critical	Warning: from value 1

Important Note – Temperature Thresholds:

Netmon compares either the raw value or the scaled value depending on the tracker configuration. Since Didactum transmits temperatures as raw value × 10 (215 = 21.5 °C), scaling must be correctly taken into account in the Performance Tracker or in the alert. Recommendation: display the raw value in the tracker and enter thresholds accordingly × 10 (28 °C = threshold 280).

Find Sensor ID:

In the Didactum Web Interface under System Tree → Select Sensor → Details or via SNMP Walk in Netmon 7 (see section 5).

7. Configure Performance Tracker for Didactum Sensors

The Performance Tracker is the central way in Netmon 7 to monitor SNMP OIDs as metrics, visualize them and set alerts on them.

Navigation

Netmon 7 → Device Dashboard → Select device "Didactum Server Room"
→ Settings (Gear-Icon) → Section „Trackers“
→ Select „Performance“ → „Add Tracker“

Tracker: Temperature Sensor

Field	Value

Save each tracker with the checkmark icon. The device dashboard will then show a separate history widget for each tracker.

8. Alert Configuration for Didactum Sensors

Netmon 7 allows assigning an alert directly to each tracker. The alert is triggered when a measured value exceeds or falls below the configured threshold.

Add Alert to a Tracker

Device Dashboard → Device "Didactum Server Room" → Settings
→ Select Tracker (e.g. "Didactum Temperature Sensor 01")
→ Click Bell Icon → "Add Alert"

Alert Label is generated automatically (editable): e.g. Temp Sensor 01 > 280
Trigger: Alert when above → enter value
Click Gear Icon for advanced options
Select Email Recipient
Save

Recommended Thresholds per Sensor Type

Sensor / Tracker	Trigger	Threshold	Interval
Temperature Sensor > Warning	Alert when above	280 (= 28.0 °C raw value × 10)	300 seconds
Temperature Sensor > Critical	Alert when above	350 (= 35.0 °C raw value × 10)	300 seconds
Leakage Detected	Alert when above	0 (from value 1 = water = immediate)	120 seconds
Smoke Detector Alarm	Alert when above	0 (from value 1 = alarm)	60 seconds
Door Contact Open	Alert when above	0 (from value 1 = open)	60 seconds
Humidity > Warning	Alert when above	80	300 seconds
Humidity > Critical	Alert when above	90	300 seconds
Device Unreachable (Ping)	Device Unreachable	–	60 seconds

Important Note – Temperature Thresholds: Netmon compares the OID raw value directly. Since Didactum transmits temperatures as raw value × 10, all thresholds must also be entered × 10. 28 °C = threshold 280.

Set Maintenance Window for Alerts

Alert Centre → Alert Manager
→ Click Calendar Icon next to the alert
  Recurrence: one-time or recurring
  Day of Week: e.g. Saturday, Sunday
  Start Time: 00:00
  Duration: 8 hours (enter in hours)
→ Save

9. Configure Email Notification

Step 1 – SMTP Configuration

Netmon 7 → Settings → Email Configuration

Field	Value
SMTP Server	mail.yourdomain.com
SMTP Port	587
Use TLS	Yes (STARTTLS)
From Address	netmon@yourdomain.com
Auth Username	netmon@yourdomain.com
Auth Password	Your SMTP Password

Click Test Email → Check inbox → Save.

Step 2 – Set Email Recipients for Didactum Alerts

Alert Centre → Alert Manager → Select Alert
→ Gear Icon → Select or create new email recipient:
  Email: admin@yourdomain.com
→ Save

Step 3 – Check Alert History

Alert Centre → Alert History

All triggered alerts are listed here with timestamp, device, message text, status and recipient. Recommended for verification after initial setup.

10. Test & Troubleshooting

Test SNMP Connection

# From the Netmon Server (or via the built-in Netmon tool):
snmpwalk -v2c -c didactum_netmon 192.168.1.50 .1.3.6.1.4.1.46501.5.1.1
# Temperature value (raw value / 10 = degrees Celsius)
snmpget -v2c -c didactum_netmon 192.168.1.50 .1.3.6.1.4.1.46501.5.1.1.7.101001
# Example output: INTEGER: 215 → 21.5 degrees Celsius
# Leakage Status (0=dry, 1=water detected)
snmpget -v2c -c didactum_netmon 192.168.1.50 .1.3.6.1.4.1.46501.5.1.1.7.107001

Check Performance Tracker

Netmon 7 → Device Dashboard → Device "Didactum Server Room"
→ Tracker Widget "Didactum Temperature Sensor 01"
→ Current value and history graph are displayed

Error Messages and Solutions

Problem	Cause & Solution
Device shows as „Unreachable“ after discovery	Community String wrong; SNMP not active on Didactum; UDP 161 blocked → test with snmpwalk
Tracker shows „No Data“	OID not supported by device; wrong sensor ID → run SNMP Walk and determine correct OID
Temperature value 10× too high (e.g. 215 instead of 21.5)	Scaling not considered in alert → enter threshold × 10 (28 °C = 280)
No email on alarm	Check SMTP settings; send test email; email recipient assigned in alert?
Leakage always shows 0	Wrong sensor ID → run SNMP Walk and read correct OID from the list
Alert is not triggered	Alert disabled (check toggle); maintenance window active; threshold set incorrectly
SNMPv3: Authentication Failure	Check Auth and Priv passwords; set Security Level (authPriv) identically on Didactum device and in Netmon
