Description Pradipta Kumar Sahoo 2020-04-13 12:50:29 UTC

Description of problem:
Currently, OSP16 OVN integration guide didn't include the tunning details for the larger-scale environment.

Version-Release number of selected component (if applicable):
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.0/html-single/networking_with_open_virtual_network/index#migrating-ml2ovs-to-ovn

Expected results:
Referring to primary bz [1], the document should enhance with the limitation and fine tunning details for larger-scale migration

Pradipta,

Can you add what those tunings are, to the BZ for tracking.

Comment 2 Pradipta Kumar Sahoo 2020-04-13 15:51:19 UTC

Hi Sai,

So far below tunning are applied in Undercloud OSP services, But it's not yet finalised as we are still troubleshooting the environment with DF team.

Heat:
	# crudini --get /var/lib/config-data/puppet-generated/heat/etc/heat/heat.conf oslo_messaging_rabbit heartbeat_timeout_threshold
	600

	# grep ^[^#] /var/lib/config-data/puppet-generated/heat_api/etc/httpd/conf/httpd.conf  | grep -i time
	Timeout 600
	KeepAliveTimeout 15

Mistral
	# crudini --set /var/lib/config-data/puppet-generated/mistral/etc/mistral/mistral.conf DEFAULT rpc_response_timeout 600
	# grep ^[^#] /var/lib/config-data/puppet-generated/mistral/etc/mistral/mistral.conf|grep timeout
	rpc_response_timeout=600

	$ sudo grep --color api_workers /var/lib/config-data/puppet-generated/mistral/etc/mistral/mistral.conf
	api_workers=12

	# grep ^[^#] /var/lib/config-data/puppet-generated/mistral/etc/httpd/conf/httpd.conf  | grep Timeout
	Timeout 600
	KeepAliveTimeout 15

	$ sudo grep --color processes /var/lib/config-data/puppet-generated/mistral/etc/httpd/conf.d/10-mistral_wsgi.conf
	 WSGIDaemonProcess mistral display-name=mistral_wsgi group=mistral processes=12 threads=1 user=mistral


Keystone:
	# crudini --set /var/lib/config-data/puppet-generated/keystone/etc/keystone/keystone.conf oslo_messaging_rabbit heartbeat_timeout_threshold 600

	# crudini --get /var/lib/config-data/puppet-generated/keystone/etc/keystone/keystone.conf oslo_messaging_rabbit heartbeat_timeout_threshold
	600

	# grep ^[^#] /var/lib/config-data/puppet-generated/keystone/etc/httpd/conf/httpd.conf |grep Timeout
	Timeout 600

Zaqar

	# crudini --get /var/lib/config-data/puppet-generated/zaqar/etc/zaqar/zaqar.conf DEFAULT rpc_response_timeout
	600

	# grep ^[^#] /var/lib/config-data/puppet-generated/zaqar/etc/httpd/conf/httpd.conf |grep Timeout
	Timeout 600

	$ sudo grep --color processes /var/lib/config-data/puppet-generated/zaqar/etc/httpd/conf.d/10-zaqar_wsgi.conf
	WSGIDaemonProcess zaqar-server display-name=zaqar_wsgi group=zaqar processes=12 threads=1 user=zaqar


Restarted services:
	$ for i in `sudo podman ps | grep -E "heat|mistral|keystone|zaqar" |awk '{print $11}'`; do sudo podman restart $i; done

Pradipta
