Enable better onboarding of new users

[pranay01]

Is your feature request related to a problem?

Currently, users who install SigNoz are shown the main login screen directly where they can create an account and log in to SigNoz.

On logging in, there is no onboarding steps currently and users are expected to know what dashboards and different sections mean. This may be OK for a user who has used the product multiple times, but for a new user this may be a steep learning curve.

Describe the solution you'd like

There needs to be improvement in the following areas in onboarding:

1. After installing SigNoz, users should be shown that the systems are installed correctly. They should be guided on how to instrument their applications and start sending data to SigNoz
2. They should be given an option to play with dummy data if they just want to explore first and not start sending data from their applications.
3. On logging in, they should be shown value very quickly. A guided walkthrough of different features and pages can be created.
4. There should be hint icons around different features, which users can hover over to learn about their feature or point to the relevant docs. This is present currently, but I think this could be improved upon.
5. There should be a page with health indicator of SigNoz's components like Query service, Otel Collector, etc. This can enable proactive action by teams if a component is getting overloaded

Describe alternatives you've considered

Add on tools which provide a walk through on current UI. Something like getlancey.com

Additional context

We can use PostHog's current onboarding flow for self hosted applications as inspiration

• Create default dashboards and alerts for users out of the box based on the services they have started sending data from. e.g. Create alerts in disabled state for RPS threshold for services which are sending data. Users can modify these alerts very easily and configure alerts based on their requirements
