What is the default folder used to install Instana agent in Linux?

IBM Instana installation and agent management documentation specifies: "By default, the Instana agent is installed to the /opt/instana/agent directory on Linux hosts." All primary binaries, configuration, and logs are contained within this root directory, though logs and runtime data are often symlinked or forwarded to standard system directories for rotation. Management scripts and configuration files reside inside this path as well—subdirectories like /etc/ and /data/ are located under /opt/instana/agent. This default directory ensures a consistent and predictable layout across distributions and matches enterprise Linux filesystem standards for third-party agents. Other directories listed (A, B, D) are for data or environment references but are not the root install directory.
