Set Up SSH Keys LogicMonitor on windows collector-step by step process

 Setting up SSH keys for LogicMonitor on a Windows Collector involves generating an SSH key pair, configuring the target devices to recognize the Collector's public key, and configuring LogicMonitor to use the SSH key for device monitoring. Here's how to do it:

1. Generate SSH Key Pair on the Windows Collector

Install Git for Windows

1. Download Git for Windows:

   • Go to Git for Windows and download the installer.

2. Install Git for Windows:

   • Run the installer and follow the installation prompts. Make sure to include the Git Bash component, which provides a Unix-like terminal on Windows.

Generate SSH Key Pair

1. Open Git Bash:

   • After installing Git for Windows, open Git Bash.

2. Generate SSH Key Pair:

   • In Git Bash, generate an SSH key pair using the ssh-keygen command:

     sh
     ssh-keygen -t rsa -b 2048 -f /c/Users/your_username/.ssh/lm_collector_key
     

   • This command generates a 2048-bit RSA key pair and saves it to C:\Users\your_username\.ssh\lm_collector_key (private key) and C:\Users\your_username\.ssh\lm_collector_key.pub (public key).
   • Follow the prompts to save the key pair (press Enter to accept the default file location) and optionally provide a passphrase for additional security.

2. Copy the Public Key to Target Devices

1. Copy the Public Key:

   • Use the ssh-copy-id command (if available in Git Bash) or manually copy the public key to the target device(s).

   • If ssh-copy-id is not available, display the public key:

     sh
     cat /c/Users/your_username/.ssh/lm_collector_key.pub
     

   • Then, on the target device, append the displayed public key to the ~/.ssh/authorized_keys file of the target user:

     sh
     echo "ssh-rsa AAAAB3Nz..." >> ~/.ssh/authorized_keys
     

2. Set Permissions:

   • Ensure the ~/.ssh directory and authorized_keys file on the target device have the correct permissions:

     sh
     chmod 700 ~/.ssh
     chmod 600 ~/.ssh/authorized_keys
     

3. Configure LogicMonitor to Use the SSH Key

1. Navigate to LogicMonitor Settings:

   • Log in to your LogicMonitor account.
   • Go to Settings > Collectors.

2. Add SSH Key Credential:

   • Navigate to Settings > Credentials.
   • Click Add to create a new credential.
   • Set the Credential Type to SSH Key.
   • Provide a name for the credential (e.g., LM SSH Key).
   • In the Private Key field, copy and paste the contents of the private key file (C:\Users\your_username\.ssh\lm_collector_key). You can open this file in a text editor to copy its content.

3. Assign Credential to Devices:

   • Go to Resources > Devices.
   • Select the device(s) that you want to monitor using SSH.
   • Click Edit and go to the Credentials section.
   • Choose the SSH key credential you created from the dropdown list.

4. Verify SSH Key Authentication

1. Test SSH Connection:

   • From the Windows Collector server, test the SSH connection to the target device to ensure the key-based authentication works. You can use Git Bash for this:

     sh
     ssh -i /c/Users/your_username/.ssh/lm_collector_key username@target_device_ip
     

   • Ensure that you can log in without being prompted for a password.

2. Verify Data Collection in LogicMonitor:

   • After assigning the SSH key credential, verify that LogicMonitor is able to collect data from the target device.
   • Navigate to the Resources section in the LogicMonitor portal and check the device's metrics and status.

5. Configure Alerts and Reports (Optional)

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 set up SSH key-based authentication for LogicMonitor on a Windows Collector, enhancing security and ensuring seamless data collection from your SSH devices.
