Hi Chenjie, The code that you reference below is the pmon daemon code which does not need to be updated. The story requires the creation of a set of pmon configuration files and associated puppet file link operations for when the vswitch type is ovs-dpdk. Here is the existing one for ovsdb-server for OVS (not yet integrated). https://github.com/openstack/stx-integ/blob/master/networking/openvswitch/fi... It is packaged by this rpm spec. https://github.com/openstack/stx-integ/blob/master/networking/openvswitch-co... You will also require puppet changes to link to this file from /etc/pmon.d (this will register the configuration with pmon daemon). https://github.com/openstack/stx-config/blob/master/puppet-manifests/src/mod... if $::platform::params::vswitch_type == 'ovs-dpdk' { $pmon_ensure = link } else { $pmon_ensure = absent } file { '/etc/pmon.d/ovsdb-server.conf': ensure => $pmon_ensure, target => '/etc/openvswitch/ovsdb-server.pmon.conf', owner => 'root', group => 'root', mode => '0755', } From: "Xu, Chenjie" <chenjie.xu@intel.com> Date: Tuesday, January 22, 2019 at 7:53 AM To: "Peters, Matt" <Matt.Peters@windriver.com> Cc: "starlingx-discuss@lists.starlingx.io" <starlingx-discuss@lists.starlingx.io> Subject: [Starlingx-discuss] Questions on [Enhancement] OVS process monitoring and alarming Hi Matt, I’m assigned the story [Enhancement] OVS process monitoring and alarming: https://storyboard.openstack.org/#!/story/2002947 And I have several questions on this story as below: 1. Does PMON refer to the following code: https://git.starlingx.io/cgit/stx-metal/tree/mtce-common/cgts-mtce-common-1.... 2. Do I need to extend the above PMON as OVS PMON? 3. Will OVS PMON be integrated into stx-neutron? Best Regards, Xu, Chenjie
