Select the Collector you created by clicking the Name used in Step 2
Select Download
- The files you need to download are based on your Hypervisor. The options available for download are:
- iso - configuration file for your collector, this file is always required
- ova - virtual machine that the collector will run (includes disk image) for VMware
- vmdk - disk image (not needed if using the ova)
- vhdx - virtual hard disk format used for Hyper-V
- Download the iso configuration file and also the relevant file needed for your hypervisor.
If you are creating multiple collectors, you only need to download the ova file once and can use it multiple times, the important file per collector is the configuration file (iso).
Install a Collector
Based on your hypervisor follow the relevant section:
VMware vSphere
Follow the documentation from VMware:
- When asked to provide a virtual machine name, we suggest samurai-nttsh-collector
- Be sure to select the .ova file you downloaded when asked for the file to deploy your virtual machine from.
Once complete follow the VMware article to configure a datastore ISO file
- Be sure to select the .iso file you downloaded when asked to select file
The VM is now ready to be powered on.
The .iso file must be mounted at first boot to configure the Collector. Once you have validated the Collector status is Healthy in the Samurai application you must ensure the .iso is dismounted.
Microsoft Hyper-V
Follow the documentation from Microsoft:
- When asked to provide a virtual machine name, we suggest samurai-nttsh-collector
- Use the Virtual Machine Requirements when configuring memory and network
- When asked to Connect Virtual Hard Disk ensure to use the .vhdx file you previously downloaded
- For Installation Options ensure you use the .iso file you previously downloaded
Once you have completed setup of your Collector you should ensure it is running and validate the status within the Samurai application, upon initial setup this can take a little while.
Amazon EC2
Prerequisitve steps:
- Open the iso image that was downloaded from Create, Configure and Download a Collector.
- Access the subfolder named AWS and extract the cloud-init.yaml file. This file will be used later during the EC2 instance deployment.
Follow the vendor documentation from Amazon to launch a EC2 instance:
Perform the following adjustments to the vendor documentation when launching the instance:
During step 4.a, select Ubuntu as AMI.
During step 4.b*,* select the latest Ubuntu AMI
During step 5*,* select a suitable Instance Type based on estimated performance requirements while fulfilling the Minimum Virtual Machine Requirements.
During step 6 & 7, Set Key pair & Network Settings as per your AWS policies. Ensuring the the Network settings still fulfills the Connectivity required for the Collector.
Before step 8, modify the Configure storage section with the following settings:
- Adjust the Root Volume to be at least 64 GiB.
- Add a secondary volume with at least 500 GiB according to the Minimum Virtual Machine Requirements.
Secondary disk volume will be used for spooling, size it according to estimated log volume and max downtime.
Before step 8, expand the sectionAdvanced details and paste in the content of the cloud-init.yaml file into the User data section. Ensure that the check box User data has already been base64 encoded is not enabled.
Proceed with step 8 and finish the rest of the installation as per the vendor documentation.
Azure Virtual Machine
Prerequisite steps:
- Open the iso image that was downloaded from Create, Configure and Download a Collector.
- Access the subfolder named Azure and extract the cloud-init.yaml file. This file will be used later during the Virtual Machine instance deployment.
Follow the vendor documentation from Microsoft to launch a Virtual Machine instance:
Perform the following adjustments to the vendor documentation when launching the instance:
- Under the Basic tab, select Ubuntu Server 22.04 LTS as image
- Under the Basic tab, select a suitable Size based on estimated performance requirements while fulfilling the Minimum Virtual Machine Requirements.
- Under the Disk tab, add one data disk with at least 500 GiB according to the Minimum Virtual Machine Requirements.
Data disk volume will be used for spooling, size it according to estimated log volume and max downtime. - Under the Advanced tab, paste the contents of cloud-init.yaml in the Custom datafield.
All other settings such authentication, network configuration and monitoring should be configured according to company policy and best practices.
Validate Collector Status
Select Collectors from the left-hand menu
Select the relevant Collector from the presented list
View Status
| Status | Description |
|---|---|
| Offline | Collector created but not online |
| Unavailable | Collector has been online but no longer available |
| Healthy | Collector deployed and deployed add on components (including) Integrations and/or Evidence Fetchers) |
| Not-Healthy | Component(s) deployed on the Collector not healthy |
| Provisioning | Collector is in setup |
After you provision a Collector VM and start it, it will go through a process of installing updates and modules specified in the configuration ISO file which you downloaded. The time taken for this process is dependent on factors like the speed of the hardware you are running the Collector on and connectivity to the repositories that it downloads updates from. In some cases this process can take around 30 minutes.
The Collector may show as “Offline” during the initial provisioning steps. This is not any cause for alarm.
If you have any problems, please submit a request via the Samurai MDR web application.
Collector Status Notifications
Samurai will send email notifications to registered application users should your Local Collector status change from Healthy to Not-Healthy or Unavailable. Once any issues have been resolved, you will also be notified again when a Healthy status is reached.
If your Local Collector be restarted, during final startup you may notice the Status change from Healthy to Not-Healthy, this is not cause for alarm as this typically occurs for a short period of time as processes restart. Once complete your Local Collector status will be displayed as Healthy.
What’s next?
You should now have a collector running within your environment!
The next step is to start configuring integrations which will allow the Samurai platform to start receiving your telemetry data.
Select Integrations Overview for more information on integrations and where to start.
If you require high availability for your collector, this can be achieved using the capabilities of your virtualization platform.
Deleting a Collector
If you delete a local collector it cannot be reversed! In addition, all of your integrations related to the local collector will also be deleted!
If you need to delete a local collector you can do so by following the steps below:
- From your Samurai application select Collectors
- Select the relevant collector from your list
- On the right hand side of the relevant collector, click on
(more options) and select Delete Collector - The following warning will appear: ‘Warning: This is a destructive action and cannot be reversed.’. To ensure you intended to delete the collector you will need to type DELETE in the field and select Delete Collector
Replacing a Collector
If for some reason a Local Collector VM is lost due to corruption or damage, such as in the case of a major disk storage failure, you may need to replace your Collector. If this happens, you will need to delete the old Collector in the Samurai MDR application, discard your old Collector VM image and then create a new Collector using the process described to Install a Collector.
Important Notes:
- If you need to replace a Collector VM, you cannot re-download the installer ISO for an existing Collector and redeploy it. You must delete the old Collector and replace it with a new one.
- You can re-use the same IP address as your old Collector. This allows you to replace a Collector without re-configuring any log sources which were sending logs to the old Collector.
- When replacing a Collector, any Integrations which were automatically detected and attached to the original Collector will be automatically detected and attached to the new Collector.
- Once you have created the new Collector, you will need to add any Integrations which you were previously using and which you had to previously manually add to the old Collector.
