Assignment:
Infrastructure TSE Candidate Technical Challenge
Sign up for a free New Relic account
[1] and install the Infrastructure agent
[2] on a host of your choice to start monitoring it. The Infrastructure agent can be installed on a Windows or Linux device you have access to, or you can sign up for the AWS free tier
[3] and spin up an Amazon EC2 instance.
Once your instance is running and instrumented, use the data explorer and query builder (accessible from the "Query your data" link near the top right of most pages) to familiarize yourself with the data being received from your host, which will reported as attributes within the events StorageSample, ProcessSample, and several others.
Please answer any two of the following questions:
Question 1: You receive an email from a customer reporting that they have a host with the Infrastructure agent installed and running, and an application running on the host is performing poorly. Write a reply providing three attributes found in events generated by the Infrastructure agent that you would recommend they monitor, and how they can interpret those attributes. (Is a high value or a low value a sign of trouble? What is the potential impact of that value?)
Question 2: You receive an email from a customer in which they report the name displayed for the host in New Relic is not correct, or not what they want it to appear as. Review our documentation on Infrastructure agent configuration settings [4], then write a reply recommending an option to set in the agent configuration that may address their issue. You may want to try setting the option on your own host first to observe the impact.
Question 3: A customer calls in stating that they have installed the Agent but are not seeing any data for their host in New Relic: What are some potential causes of this? What configuration options [4] might help the customer in this situation?
Question 4: Describe the steps to take and commands to use in order to complete the following process with only a command line interface (bash, Windows command prompt, or PowerShell):
? Enable verbose logging by adding the following options to the agent configuration: verbose: 1 log_file:
? Restart the agent service after saving the configuration changes.
? Search the log for lines containing the text proxy using only the command line (bash, Windows command prompt, or PowerShell).
? If you intend to keep using the host after this exercise is complete, disable verbose logging again when finished to prevent excess log accumulation.
