Installing Gremlin on Windows
Windows is not supported for Reliability Management.
If you're installing Gremlin on an Azure Windows instance, be aware that Azure may throttle disk I/O such that large disk experiments will take an excessive amount of time to complete.
General steps for deploying the Gremlin Agent on Windows:
Gather your credentials
All Gremlin integration installations require authentication with the Gremlin Control Plane. We recommend using the Client Configuration File method, as it contains everything needed to authenticate and configure the Gremlin Agent in one file. To create and download a client configuration file:
- Access the Team Settings page in the Gremlin web app.
- Click the Configuration tab.
- On the Client Configuration File line, click Download to download the file. You'll receive a file named
- Optionally, make any additional configurations to the
If you wish to use another method of authenticating, see the Authentication docs.
Install the Gremlin Agent
Run the following from an elevated command prompt and continue through the installation wizard:
1msiexec /package https://windows.gremlin.com/installer/latest/gremlin_installer.msi
To automate the installation (e.g. for auto-deploying Gremlin onto new instances), use the following command:
1msiexec /quiet /package https://windows.gremlin.com/installer/latest/gremlin_installer.msi
The minimum configuration required to authenticate the Gremlin Agent is:
- Team ID
- Secret or certificate
If you downloaded a client configuration file, you already have everything needed to register the Agent. Just follow these instructions:
Copy the configuration file (named
config.yaml) to the
C:\ProgramData\Gremlin\Agentdirectory. The final path should be
C:\ProgramData\Gremlin\Agent\config.yaml.PowerShell1Copy-Item "config.yaml" -Destination "C:\ProgramData\Gremlin\Agent\config.yaml"
gremlindservice:PowerShell1Restart-Service -Name gremlind
Validate the installation
There are two ways to ensure your installation was successful and your Agents authenticated successfully:
Check the Gremlin web app
The easiest way to verify connectivity is to open the Agents list in the Gremlin web app. Check for your newly installed Agent by name or by tag. You can also use the search box to search by name or tag, Agent version, operating system (OS), or region. If your Agent does not appear in this list, it may not have been installed or configured correctly, or it might not be able to reach Gremlin's servers.
Check the Gremlin Agent
First, verify that the Gremlin Agent is running on the target system:
This should return the following:
1Status Name DisplayName2------ ---- -----------3Running gremlind Gremlin Daemon
If the service is instead reporting as inactive or failed, try restarting the service using:
1Restart-Service -Name gremlind
After verifying that the Gremlin Agent is running, use
gremlin check auth to check the Gremlin Agent's authentication status:
1& 'C:\Program Files\Gremlin\Agent\gremlin.exe' check auth
If the Gremlin Agent authenticated successfully, the output will be similar to the following:
1auth2====================================================3Auth Input Type : Certificate4API Response : OK
If not, the output will explain why the Gremlin Agent was unable to authenticate:
1auth2====================================================3Auth Input Type : No valid auth found4========= Identification ============:5Team ID Source : Team ID not found6Gremlin Identifier : [Host identifier]7Gremlin Identifier Source : Not supplied explicitly, using the default8========= Secret/Token Info =========:9Team Secret Source : Team Secret not found10.credentials valid : /var/lib/gremlin/.credentials file not found11========= Certificate Info ==========:12Team Certificate Source : Team Certificate not found13========= Private Key Info ==========:14Team Private Key Source : Team Private Key not found
If the Agent is connected but is reporting as unhealthy, see Troublehsooting Unhealthy State in the Gremlin Knowledge Base. If you're having trouble authenticating, see the Authentication FAQ in the Gremlin Knowledge Base for possible causes and solutions.
