feature: at install scan localhost for existing services and enable them

[ssbarnea]

This would be a huge benefit to dd-agent, the auto-configuraiton on install. The agent could scan the localhost filesystem and portscan for different running services and to enable the automatically.

Few examples of things that can be implemented with minor effort:

• detect any JMX open port on localhost (it can be more than one)
• detect nginx, apache webservers
• detect postgres, "su - postgres -c psql" should always work
• detect mysql
• detect jenkins
• add http checks for each virtual host on nginx or apache (maybe later)

Obviously this cannot be made for all services but if you make it for top 10%, you would increase the user experience for 90% of the cases.

Also, you could allow us to contribute with detection codes for these services.

Hi @ssbarnea .

That's a nice idea, it's going to need further discussion as there are downsides that can be discussed:

• Performance: Scanning ports can take a bit of time
• Test servers with multiple services enabled. If you install the agent and 15 integrations are enabled, it could process a decent amount of data.
• Services that are present on a server but are really not critical, or worth monitoring.

There is definitely something to do to improve user's first experience with the Agent.
We would be happy to hear any feedback from you about it!
