It appears wily was somehow added to the CA PM implementation and ended up writing log files to wily directory which filled up the disk.
The customer does not have APM so not sure how this happened.
Can we uninstall the wily that comes with CA PM?
I could find the procedure to add wily implementation but not to remove.
By Default, the CAPM install includes the Application Performance Management (APM) agents to allow for additional monitoring of your environment.
to disable the APM integration:
On the CAPC,
In wrapper-user.conf, comment out the lines for wily
Do the same on DM, EM and sso sub-directories.
On the DA and DC
Edit the _capm file and remove the entry that points to the wily host.
Recycle all services on all systems that you edit.
