Configure the additional external storage

Set up AWS S3 external storage in Crosswork Network Controller when prompted to ensure continued access to monitored data as internal storage approaches capacity.

Service Health provides internal storage of monitored data up to a maximum limit of 50 GB. The data includes the VPN service status at the time of storage and historical data about the service.

This data is stored by Service Health on your system in the tar.gz archive file format. Each tar.gz file represents an EOS. Service Health uses this data to display it visually in the Crosswork Network Controller UI when you click on an EOS.

When the storage reaches 70% capacity, Crosswork Network Controller generates an alarm prompting you to configure external storage. Service Health automatically deletes the least recently used files when 80% of the 50 GB storage capacity is reached.

When you configure external storage, most internal storage data is automatically moved to external cloud storage, while a portion remains locally in internal storage to serve as a cache for improved performance.

You can use an Amazon Web Services (AWS) cloud account to configure external storage in the cloud. Only AWS S3, an object storage service, is supported.

After you configure AWS storage, only 80% of the 50 GB space or 100,000 files are stored locally in Crosswork Network Controller. The remaining files are automatically moved to AWS.

Before you begin

You must have an AWS cloud account set up to configure the external storage.

Procedure

Step 1

From the main menu, choose Administration > Settings and click the Storage settings tab.

Step 2

With the Overview tab selected, select Configure under the External storage section. The Configuration screen appears, and the Data storage type and S3 provider fields are pre-populated with AWS.

Step 3

Provide your AWS authentication information for all required fields, such as Access key, Secret key, Endpoint, and others.

Step 4

Select Copy local data if you want all files previously stored in the local cache to be copied in bulk to external storage. This action enables incremental upload of new files.

Note

 
This option is a one-time action when moving from only maintaining local storage and moving to external storage. This action also helps to improve the application performance.

Note

 

The Expiry period refers to the number of days that historical data files will be stored before being deleted. For example, if the Expiry period is set to one (1), the files will be deleted two days later, at midnight in the operational time zone on the second day.

Step 5

Click Test and save.

Step 6

To check the health of your storage setup, click the Diagnostics tab and click Run test.

By running a test, you can review the external storage diagnostics such as bandwidth, latency, and multiple access test details to help identify possible storage performance issues.
