RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
The pmchart in record mode on local system throws error "Host "local:" cannot be matched to an open archive for <metric_name>". The pmafm also shows the mismatch error
pmafm> check
Archive: /home/yogesh/.pcp/pmlogger/local:/20200415.03.49.55 ... Errors
Hostname mismatch: folio=local: archive=pcp
My hostname is 'PCP'.
Version-Release number of selected component (if applicable):
pcp-4.3.2-3.el8_1.x86_64
How reproducible:
Steps to Reproduce:
1. on a localhost system
2. pmchart
3.choose record
4. add any view
5. stop the recording
Actual results:
you will get the error - "Host "local:" cannot be matched to an open archive for <metric_name>".
Expected results:
the folio written by pmchart when entering record mode should change local: and localhost to the actual hostname, to match the archive
Additional info:
If you comment out the PMCD_LOCAL=1 from /etc/sysconfif/pmcd and start using the #pmchart -h <localhost_name> it works and it does capture the correct folio with correct hostname.
Also, using #pmchart -h <remote_hostname> also works.
It only fails on localsystem.

pmchart: record mode - save actual hostname instead of local: in views and folios
Hostname in the view and folio needs to match the the archive label,
otherwise pmafm can't match up archives with views.
Resolves: RHBZ#1824403
Regression reported by QA fixed upstream for pcp-5.2.2 :
commit c18e0033d9c1a2bd0b3cd248173c6901c0ec25e1

pmchart: record mode, keep "local:" arg for launched pmloggers
When pmchart "record mode" launches a pmlogger for host "local:",
don't resolve the argument to the local hostname because pmlogger
may not then be able to connect to the local PMCD if PMCD_LOCAL=1
is set in sysconfig. Pmlogger already correctly handles translation
of "local:" for the archive label.
