AppDynamics

The service.For example: service appdynamics-machine-agent startLink for Environment VariablesSysV – /etc/sysconfig/appdynamics-machine-agent >> /opt/appdynamics/machine-agent/etc/sysconfig/appdynamics-machine-agent CODE This script sets up the environment variables: MACHINE_AGENT_HOME=/opt/appdynamics/machine-agent – Specifies where the agent files are located.JAVA_HOME=/opt/appdynamics/machine-agent/jre – Specifies the JRE the agent uses. AppDynamics recommends that you use the RPM package installer that contains its own JRE. However, you can use a different JRE as long as it meets the JRE requirements.MACHINE_AGENT_USER=root – Specifies the system user for starting the agent (default is root). AppDynamics recommends that you create a non-root user to run the machine agent. The new user needs to have read-access to controller-info.xml and write access to the log file. See Permissions Required to Run the Machine Agentsystemd – The environment variables are in the service file: /etc/systemd/system/appdynamics-machine-agent.service >> /opt/appdynamics/machine-agent/etc/systemd/system/appdynamics-machine-agent.service CODE "MACHINE_AGENT_USER" variable doesn't exist in the systemd service file. The variable is just User. Link for Agent to Controller CommunicationSets up a link to the controller-info.xml file containing the properties for agent-to-controller communication. /etc/appdynamics/machine-agent/controller-info.xml >> /opt/appdynamics/machine-agent/conf/controller-info.xml CODE Logging ConfigurationThe log4j.xml file controls the detail of information logged by the agent. By default, the logging level is set to info. /etc/appdynamics/machine-agent/logging/log4j.xml >> /opt/appdynamics/machine-agent/conf/logging/log4j.xml CODE Adds the Agent as a ServiceAfter the package is installed, the appdynamics-machine-agent runs opt/appdynamics/machine-agent/bin/postInstall.sh to add the agent to the services. The installer either copies the SysV script to add the service or, if systemd is detected, the installer copies the agent unit file /etc/systemd/system/appdynamics-machine-agent.service and adds the agent to the services using this unit file.Installs a systemd Unit

And account access key. (Optional) Review memory requirements. See Machine Agent Requirements and Supported Environments.(Optional) Configure the agent to use SSL. See Enable SSL for Machine Agent.(Optional) Configure the agent to use proxy settings. See Machine Agent Configuration Properties.(Required for Multi-Tenant Mode or SaaS installations) Configure the Agent Account Information. See Multi-Tenant Controller Accounts.(Optional) Determine if you need to specify an application name and tier name. See Machine Agent Installation Scenarios.If you are installing the Machine Agent on the same server with any APM app agent, do not specify application name and tier name.Start the Agent. You can start the agent as a service (requires sudo or root user) or from the command line. If systemd was detected during installation, you can use the systemctl command to start the agent service. Using SysV – service appdynamics-machine-agent startUsing systemd – systemctl start appdynamics-machine-agentFrom the Command Line – /bin/machine-agentFrom the Launcher – machine_agent_home>/etc/init.d/appdynamics-machine-agent startRPM Package FunctionThe RPM package manager installs the agent files to opt/appdynamics/machine-agent, creates symbolic links, sets environment variables, and adds the agent as a service.Symbolic Links The RPM package manager creates the symbolic links to agent scripts and configuration files in the /etc directory. You can edit these links to accommodate a different installation directory, JRE, or system user account running the agent. Link for SysV Service Script/etc/init.d/appdynamics-machine-agent >> /opt/appdynamics/machine-agent/etc/init.d/appdynamics-machine-agentThis script provides these service commands:Start – Starts the service, runs a script that starts the agentStop – Stops the serviceRestart – Restarts the serviceStatus – Returns the status of
