Platform FAQ

What are the prerequisites for system configuration when using the on-premises architecture?
Please consult the System Requirements Section in the Installation Guide for more details
What firewall settings are required when using the on-premises architecture?
To ensure seamless communication, follow these firewall configuration steps:
1.Agent Communication with Datasentinel Platform:

Enable bidirectional communication (push and pull) between the agents and the DataSentinel platform.
Specify the platform server address.
The default port for communication is 443
2.Platform to Agent Communication:
Configure the Datasentinel platform to communicate with the agents.
Establish one-way communication: Platform to agent.
The default agent port is 8282; feel free to modify it using the Agent CLI or Agent API.
What firewall settings are required when using the SAAS architecture?
To ensure seamless communication, follow these firewall configuration steps:
1.Agent Communication with DataSentinel Platform:

Allow bidirectional communication (push and pull) between the agents and our DataSentinel platform.
Specify the server as: <<server name provided by Datasentinel team>>
The port to be opened is: 443.

2.User PC to Agent Communication:
Configure the user PCs to communicate with the agents.
Ensure one-way communication: User PC to agent.
The default port for agent communication is: 8282. You have the flexibility to customize the agent port using either the Agent CLI or the Agent API.​
What's the process for modifying the default self-signed certificate?
If you wish to replace the default self-signed certificate with your own for the on-premises platform, adhere to the following steps:
1.Existing Self-Signed Certificate: Be aware that the on-premises platform utilizes a self-signed certificate configured through NGINX. This certificate is stored within the /etc/nginx/certs directory.
2.Generate Your Certificate: Generate a certificate suitable for your platform machine. It should adhere to security standards and compatibility prerequisites.
3.Certificate Replacement: Substitute the current cert_datasentinel.pem and key_datasentinel.pem files with your actual certificate and private key files.
4.Restart NGINX: After the certificate files have been updated, restart NGINX to ensure the seamless integration of your new certificate.
By following these instructions, you can enhance your on-premises platform's security by substituting the default self-signed certificate with a custom one of your choosing.
What is the data retention policy?
As a default, data is retained for a duration of 14 days. This retention period maintains consistent precision throughout the entire timeframe.
However, you possess the ability to adjust this retention period to align with your specific requirements. To effect this change:
1.Access the Global Settings submenu.
2.Input the desired retention period.
Please Note:
Each platform features its own distinct data retention policy.
Multiple platforms can maintain diverse retention periods. For instance, you might have one platform tailored for production clusters and another for non-production clusters.
Does the platform create log files?
Datasentinel generates logs, which are located in the /datasentinel/log directory, except for the NGINX log file.
The primary log file, datasentinel.log, serves as a valuable resource for debugging purposes.

For additional details, please refer to the dedicated Log File section within the platform installation guide.
How can I establish NGINX access logs?
To enable or disable access logs, utilize the following steps:
1.Access Configuration File: 
Open the configuration file /etc/nginx/conf.d/datasentinel.conf.

2.Adjust the access_log Parameter:
For enabling access logs:
access_log /var/log/https_datasentinel.log combined if=$loggable;
For disabling access logs:
access_log off;
3.Reload Nginx: 
After making the changes, reload Nginx for the modifications to take effect. 
Use the command:
/usr/sbin/nginx -s reload
By following these instructions, you can conveniently enable or disable Nginx access logs as needed to monitor or restrict the logging of incoming requests.
How to check the status of platform components?
Consult the Component Management Section of the platform documentation
What's the process for setting up InfluxDB logs?
It's advisable to deactivate the generation of logs by the InfluxDB database. 
To achieve this, make the following parameter adjustments within the configuration file located at 
/datasentinel/soft/influxdb-1.7.6-1/etc/influxdb/influxdb.conf:
1.[data] Section:
Set query-log-enabled = false to prevent logging queries before execution.
2.[http] Section:
Set log-enabled = false to disable HTTP request logging.
Set suppress-write-log = true to suppress write request logs when the log is enabled.
3.[logging] Section:
Specify the desired log level (e.g., error, warn, info, debug) with level = "error".
After making these changes, you need to restart InfluxDB for them to take effect. Use the command:
sudo systemctl restart datasentinel_influxdb
Please be aware that restarting the InfluxDB database might take some time depending on its size.
For more detailed information, consult the InfluxDB Section
