Write a summary on Apache tomcat, MySQL & kubernetes application addition in Datadog

Datadog provides integration with 500+ various technologies. Apache tomcat, MySQL & kubernetes are fully supported. I will summarize the Apache tomcat technology integration with Datadog. First we need to install Apache tomcat on server which is being monitored by Datadog. Assuming server is already setup with basic monitoring. After installation we have to configure Apache tomcat to expose its health stats. Configure datadog agent configuration file to include Apache tomcat parameters for monitoring. On datadog website install Apache tomcat extension and enjoy the flawless monitoring of Apache tomcat.
Next lets summarize MySQL monitoring. First we need to install MySQL on that server. MySQL stores all health stats in a Database name performance. Now to monitor the database we need to create a user for Datadog agent and provide access performance database. Configure Datadog configuration file to use same username and password to access performance database. On datadog website install MySQL extension and enjoy the flawless monitoring of MySQL.
Kubernetes monitoring is bit different kubernetes required pods to monitor health on kubernete cluster. For configuration download the required configuration file and edit it as per environment. Execute command to create pods to monitor the cluster. In test environment don't forget to disable SSL communication else pods will not be created.

Datadog Assignment Day-1

Top 7 commands of Datadog agent and its use cases
Ans - Top 7 commands of Datadog agent and its uses are as below:
a) Datadog-agent config :- This command is used for runtime configuration management. It is used to validate the configuration as loaded by Datadog agent.
b) Datadog-agent config-check :- This command prints all configuration currently used by Datadog agent. It is used to validate the desired and loaded configuration.
c) Datadog-agent health :- This command is used to get agent health. It is used to verify health on agent.
d) datadog-agent hostname :- This command is used to print hostname currently used by agent. It is used to validate the agent is using the correct hostname.
e) Datadog-agent help :- This command is used to get help of any agent command. It is used to get help about agent commands.
f) Datadog-agent import :- This command is used to import configuration of older version of agent. It is used in agent uprade on servers.
g) Datadog-agent version :- This command used to get agent version information. It is used to check running agent version.

What is observability?
Ans- In current complex application environment , bare monitoring is not sufficient for application reliability, availability and sturdiness. We require to include various parameters to add along with traditional monitoring. We can call this combined stuff as observability which ensure good application health and reliability.
How to practice observability?
Ans- Observability performs the basic checks to validate the application. This will ensure all parameters are validated and problematic logs separated to perform further troubleshooting.
What are the datatypes we need to collection to setup observability ?
Ans - We need to follow MELT to setup observability.
Monitoring, Events, Logs and Testing are all components to be consider in this.
