How do I gather performance data logs to upload to my support case using Performance Co-Pilot (PCP)

• first install and configure PCP for performance data collection on the local server, see How do I install Performance Co-Pilot (PCP) on my RHEL server to capture performance logs
• create a tar archive of the captured performance data

tar czf /tmp/pcp-$(hostname)-data.tgz /var/log/pcp

• upload the resulting /tmp/pcp-<hostname>-data.tgz to the case.
• sos-3.2-3 and later versions automatically include PCP logs in the sosreport. With that sos version, just capturing a sosreport will include the PCP archives located below /var/log/pcp.

Verifying the time span covered by archive files

The full directory /var/log/pcp might be big, it can make sense to identify which archive files cover a certain time span and then upload these. Example:

[chris@космос ~]$ cd /var/log/pcp/pmlogger/kosmos.local/
[chris@космос kosmos.local]$ ls -al
