Distributed-Domain
Prerequisites
Step 1: Download Trisul
Download the Trisul network monitoring platform from the official website.
Step 2: Install Trisul Components
- Install Hub and Webtrisul on the Trisul-hub server.
- Install Probe on the Trisul-Probe server.
Step 3: Verify Expect Script
Ensure that the Expect script is present on your system. If not, install the Expect package.
Important Licensing Note
Please note that 7-day trial licenses are not supported for Distributed-Domain setup. Ensure you have a valid license before proceeding with the setup.
Installing and Configuring Trisul Probe
Step 1: Install Expect
Run the following command to install Expect:
- UBUNTU
- RHEL
sudo apt install expect
sudo yum install expect
Step 2: Install Trisul Probe
- Install the Trisul Probe on the Trisul-probe server.
- For multiple probes, install the probe on each server.
Step 3: Configure SSH
Configure SSH on all Trisul servers.
Enabling Distributed Domain on Trisul-Hub Server
To enable Distributed Domain on the Trisul-Hub server, follow these steps:
Step 1: Run the Distribution Script
On the Trisul-Hub server, run the following script:
/usr/local/share/trisul-hub/hub_distributer.exp
Step 2: Provide Required Inputs The script will prompt for the following inputs:
- Hub-Server IP
- Description
- Starting port
Enter the required details to complete the Distributed Domain setup.
| Parameters | Sample Inputs |
|---|---|
| Hub IP Address | 192.168.1.6 |
| Domain Description | Distributed domain |
| Starting Port | 12001 |
The installation process will now commence, and the server will be converted into a Distributed Domain configuration.
Adding Trisul Probe to Trisul Hub
Step 1: Run the Probe Addition Script
Run the following script on the Trisul Hub server:
/usr/local/share/trisul-hub/add_probe.exp
| Parameters | Sample Inputs |
|---|---|
| Probe-Name | probeWEST |
| Probe-ssh-IP addr | 192.168.1.7 |
| Probe-ssh-username | demo-user |
| Probe-ssh-Password | demo-passwd |
This script connects a Trisul-Probe to a Trisul-Hub. To connect multiple Trisul-Probe instances, simply run the script again after installing each probe and provide the respective probe details. Repeat this process for each additional Trisul-Probe to establish connections with the Trisul-Hub.
Step 2: Provide Required Inputs
The script will prompt for the following inputs:
- Probe Name (must start with "probe" followed by the name, e.g., "probeWEST")
- Probe SSH IP Address
- Probe SSH Username
- Probe SSH Password
Step 3: Verify Probe Connection
To verify that the probe is connected, run the following command:
/usr/local/bin/trisulctl_hub hello
This will display a list of connected probes.
Troubleshooting
If the probe is not listed, restart the Hub and Probe:
On the Trisul Hub server:
/usr/local/bin/trisulctl_hub restart domain
On the Trisul Probe server:
/usr/local/bin/trisulctl_probe restart domain
Then, re-run the command to verify the probe connection.
