SNMP

🎯 Purpose​

Enable the Watchman agent to collect network information via the SNMP protocol.

🐧 For Linux​

# Update the package list
sudo apt-get update

# Install the snmpd package
sudo apt-get install snmpd

2. Configure the SNMP configuration file​

sudo nano /etc/snmp/snmpd.conf
  • Set the SNMP community string (e.g., public)
  • Allow the IP addresses from which the agent will query
  • Restart the service:
sudo systemctl restart snmpd

3. Open the SNMP port​

sudo ufw allow 161/udp

For Windows​

1. Enable the SNMP service​

  • Go to Control Panel → Programs and Features

🧠 Proper SNMP configuration ensures smooth network data collection by the Watchman agent.
