#Prerequisites

Before you deploy Network Observability, make sure that you have:

• Access to the platform as an administrator
• The NetObserv Operator package, which is installed in the fixed namespace netobserv-operator
• A reachable ClickHouse server, either existing or newly deployed
• ClickHouse credentials that can be stored in a Kubernetes secret

#Kernel Requirements

The minimum kernel version for the eBPF agent is 5.14.

On Ubuntu, the kernel.perf_event_paranoid parameter must be set to 3 or lower. This allows unprivileged processes to use the perf_event_open() system call, which is required by the eBPF agent.

To check the current value, run:

sysctl kernel.perf_event_paranoid

If the value is greater than 3, set it to 3:

sysctl -w kernel.perf_event_paranoid=3

To make this change persistent, add the following line to /etc/sysctl.conf:

kernel.perf_event_paranoid=3

#Prepare the NetObserv Operator Package

Before installing the operator, obtain the NetObserv Operator package and upload it to the platform.

#Download the Package

Visit the Customer Portal to download the NetObserv Operator package.

If you don't have access to the Customer Portal, contact technical support.

#Upload the Package

Use the violet tool to publish the package to the platform.

For detailed instructions on using this tool, refer to Upload Packages.
