Step by step process on how to discover snmp device in logicmonitor

Discovering SNMP devices in LogicMonitor involves several steps, including configuring the LogicMonitor Collector, setting up SNMP on the target devices, and creating or using existing DataSources. Here’s a detailed guide on how to discover SNMP devices in LogicMonitor:

1. Configure the LogicMonitor Collector

Install the Collector

1. Download the Collector:

   • Log in to your LogicMonitor account.
   • Navigate to Settings > Collectors.
   • Click Add to download the Collector installer for your operating system.

2. Install the Collector:

   • Run the installer on a server or virtual machine with network access to the SNMP devices.
   • Follow the installation instructions.

3. Register the Collector:

   • During installation, you’ll be prompted to register the Collector with your LogicMonitor account. Follow the prompts and enter the required credentials.

Ensure Collector Has Network Access

• Verify that the Collector server can reach the SNMP devices over the network.
• Ensure that firewall rules allow SNMP traffic (typically UDP port 161).

2. Set Up SNMP on Target Devices

Configure SNMP on Devices

1. Enable SNMP:

   • SNMP must be enabled on each device you want to monitor. The process varies depending on the device type (e.g., routers, switches, servers).
   • Commonly, this involves accessing the device's management interface and enabling SNMP, setting the SNMP version (v1, v2c, or v3), and configuring community strings or user credentials.

2. Configure SNMP Access Control:

   • Set the community string (for SNMP v1/v2c) or the user credentials (for SNMP v3).
   • Define the IP addresses or ranges that are allowed to query the device via SNMP.

3. Create or Use Existing SNMP DataSources

Use Predefined DataSources

1. Navigate to DataSources:

   • In the LogicMonitor portal, go to Settings > DataSources.

2. Search for Predefined DataSources:

   • LogicMonitor provides a library of predefined DataSources for common SNMP devices. Search for DataSources relevant to your device type (e.g., Cisco, Juniper, etc.).

3. Import DataSources:

   • Select and import the necessary DataSources into your LogicMonitor account.

Create Custom SNMP DataSources (if needed)

1. Create New DataSource:

   • If a predefined DataSource does not exist for your device, you can create a custom SNMP DataSource.
   • Go to Settings > DataSources > Add.

2. Define DataSource Parameters:

   • Specify the SNMP OIDs (Object Identifiers) to be monitored.
   • Set the polling interval, instance discovery method, and any necessary transformations or calculations.

4. Add SNMP Devices to LogicMonitor

1. Navigate to Devices:

   • In the LogicMonitor portal, go to Resources > Devices.

2. Add New Device:

   • Click Add to add a new device.
   • Enter the device’s IP address or hostname.
   • Select the appropriate Collector to monitor the device.
   • In the Credentials section, enter the SNMP credentials:
     • For SNMP v1/v2c: Enter the community string.
     • For SNMP v3: Enter the username, authentication protocol and password, and privacy protocol and password.

3. Save and Discover:

   • Click Next and then Add Device.
   • LogicMonitor will attempt to communicate with the device using the provided SNMP credentials and will automatically apply the relevant DataSources.

5. Verify Device Discovery

1. Verify Data Collection:

   • After adding the device, navigate to the device in the Resources section.
   • Verify that data is being collected and displayed for the device.
   • Check that the appropriate DataSources are applied and that the metrics are being updated.

2. Troubleshoot Issues:

   • If data is not being collected, check the SNMP configuration on the device and ensure the Collector has network access.
   • Verify that the correct SNMP credentials are used.
   • Check the LogicMonitor logs for any errors related to SNMP communication.

6. Configure Alerts and Reports

1. Set Up Alert Rules:

   • Define alert thresholds for the collected SNMP metrics to receive notifications when specific conditions are met.

2. Create Reports:

   • Use LogicMonitor’s reporting features to generate reports on the performance and status of your SNMP devices.

By following these steps, you can effectively discover and monitor SNMP devices in LogicMonitor, ensuring comprehensive visibility into your network infrastructure.
