Red Hat Bugzilla – Bug 1591027
Update rhui-debug.py to collect information for RHUI 3+
Last modified: 2018-07-10 12:00:58 EDT
Description of problem: rhui-debug.py that was shipped in RHUI 3 is the same as RHUI 2. Since it was not updated, we receive no information in a rhui-debug from RHUI 3+. Version-Release number of selected component (if applicable): 3.0+ How reproducible: 100% Steps to Reproduce: 1. Run rhui-debug.py Actual results: No useful data collected. Expected results: Full rhui-debug with data pertinent to RHUI 3. Additional info: Have created a patch to work with RHUI 3 useful information, plus a few additional new features for one-off rhui-debug runs. (Can grab mongodb logs and auto-xz compress the debug into a tar.) Will add patch here after BZ creation.
Created attachment 1451074 [details] Update rhui-debug for RHUI 3
The problem is that in RHUI 3 the /usr/share/rh-rhua/rhui-debug.py script is part of the rh-rhui-tools package, which is NOT installed on CDS nodes. Therefore, "sosreport -o rhui" only produces: [root@cds01 sosreport-cds01.example.com-20180627053658]# find . ./sos_commands ./sos_commands/rhui ./sos_commands/rhui/rhui-debug ./sos_logs ./sos_logs/sos.log ./sos_logs/ui.log ./sos_reports ./sos_reports/sos.html ./sos_reports/sos.txt ./version.txt And: # cat sos_commands/rhui/rhui-debug python: can't open file '/usr/share/rh-rhua/rhui-debug.py': [Errno 2] No such file or directory It's not really feasible to want to install rh-rhui-tools by hand in order to be able to get nice sos reports from the CDS as there's a pretty wild dependency tree, including pulp-rpm-plugins, which tries to touch /var/lib/pulp, which is a symlink to a read-only filesystem on the CDS, so the installation fails. Moreover, /usr/lib/python2.7/site-packages/sos/plugins/rhui.py (from the sos package) reads: if self.is_installed("pulp-cds"): cds = "--cds" else: cds = "" But there's no pulp-cds in RHUI 3 anymore. When I hack this part of rhui.py and also copy rhui-debug.py to the CDS by hand, I get a tarball with a collection of the expected files. So it seems we need an update of sos and I guess we'll have to move debug.py to the rh-rhui-tools-libs, which IS installed on the CDS. (This is not a regression in the updated debug.py file as the root cause is in rhui.py, so I think we can move on for now.)
I think I should add that everything is fine on the RHUA node. I also tried running debug.py directly (outside of sos) and with -m, and got a collection including mongodb config files and log.
