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.

Red Hat Product Errata RHBA-2018:0879 0 normal SHIPPED_LIVE tuned bug fix and enhancement update 2018-04-10 13:39:08 UTC

Description Jiří Mencák 2017-06-15 12:34:11 UTC 
Description of problem:
There is currently no way of "recommend"ing a profile based on processes running on the system.  I believe it would be useful if a "tuned" user could specify (in /etc/tuned/recommend.conf) something like

[my-profile-based-on-existing-process-name]
process=<regex>

Multiple process=<regex> key-value pairs within a profile section would serve as a logical AND condition, i.e. the profile would only be selected if all processes were running on the system.

Version-Release number of selected component (if applicable):
tuned-2.8.0-4.el7.noarch

Additional information:
At the moment the motivation for this is selecting a tuned profile for an Openshift router based on the presence of a haproxy process, but I'm sure there might be other use cases.
Comment 2 Jaroslav Škarvada 2017-06-15 14:24:59 UTC 
I think it will be beneficial.

Unfortunately the current parser (configobj) doesn't allow multiple keywords (i.e. multiple 'process=regex' lines), but it shouldn't be problem to differentiate it by unique suffix, e.g.:

process=regex1
process1=regex2
process2=regex3
Comment 3 Jaroslav Škarvada 2017-06-15 16:24:01 UTC

Comment 5 Jiří Mencák 2017-06-16 07:32:05 UTC 
Tested upstream patch in #3, works fine.

Verified this bug with # tuned -v
tuned 2.9.0

the node can get the correct value

# sysctl -a | grep ipv4.neigh.default.gc_thresh
sysctl: reading key "net.ipv6.conf.all.stable_secret"
net.ipv4.neigh.default.gc_thresh1 = 8192
net.ipv4.neigh.default.gc_thresh2 = 32768
net.ipv4.neigh.default.gc_thresh3 = 65536
