APM Agent cannot use the OSB extension

Products

• CA Application Performance Management Agent (APM / Wily / Introscope)

Issue/Introduction

We are having problems with the agent extensions for the OSB.

Checking the logs, we can find that the tar.gz of the extension can´t be untar and therefore the directory is not created. The rest of the errors are caused by this first failed step.

Could you tell us why it gives problems when trying to untar?

Environment

Release : 10.8

Cause

Log message pointing to permissions problem.

[DEBUG] [IntroscopeAgent.ExtensionDeployer] Cannot untar:
java.io.FileNotFoundException: description.md (The file or directory does not exist)

Resolution

After permissions problem on the directory was fixed, issue was resolved.
