Step by step process to discover ssh devices in logicmonitor

 Discovering SSH devices in LogicMonitor involves configuring the LogicMonitor Collector, setting up SSH on the target devices, and creating or using existing DataSources. Here’s a detailed guide on how to discover SSH 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 SSH 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 SSH devices over the network.
• Ensure that firewall rules allow SSH traffic (typically TCP port 22).

2. Set Up SSH on Target Devices

Configure SSH on Devices

1. Enable SSH:

   • Ensure SSH is enabled and running on each target device. The process varies depending on the device type (e.g., Linux servers, network devices).

2. Create SSH User Account:

   • Create or use an existing user account with sufficient permissions to execute the necessary commands and retrieve the required data.

3. Set Up SSH Keys (Optional but Recommended):

   • For added security, configure SSH key-based authentication. Generate a public-private key pair and add the public key to the target device’s authorized keys file.

3. Create or Use Existing SSH 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 metrics collected via SSH (e.g., CPU usage, memory usage, disk usage).

3. Import DataSources:

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

Create Custom SSH DataSources (if needed)

1. Create New DataSource:

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

2. Define DataSource Parameters:

   • Specify the SSH commands to be executed to collect the desired metrics.
   • Set the polling interval, instance discovery method, and any necessary transformations or calculations.

4. Add SSH 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 SSH credentials:
     • Use the username and password or configure the SSH key for authentication.

3. Save and Discover:

   • Click Next and then Add Device.
   • LogicMonitor will attempt to communicate with the device using the provided SSH 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 SSH configuration on the device and ensure the Collector has network access.
   • Verify that the correct SSH credentials are used.
   • Check the LogicMonitor logs for any errors related to SSH communication.

6. Configure Alerts and Reports

1. Set Up Alert Rules:

   • Define alert thresholds for the collected SSH 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 SSH devices.

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