johnsomStein upper-constraints limits us even more, so I'm pinning that.20:29
spateljohnsom: back here20:31
johnsomo/20:31
spateljohnsom: does octavia working with senlin for autoscaling?20:31
spatelI have senlin running in lab, if octavia and senlin work together then it will create AWS ELB atmosphere.20:32
johnsomspatel No. We currently don't have an autoscaling story. We have all of the metrics we need, but not the code to initiate a scale. It's planned to not require senlin.20:33
spatelAny plan in future?20:33
johnsomYeah, there are a couple of challenges that have not been addressed yet. 1. We haven't finished Active/Active, so horizontal scale isn't possible yet. 2. Nova can't hotplug CPU or RAM, if you scale those it reboots the instance.20:34
spatelIn AWS we use ELB a lot for scale up and down with LB. so thinking to try that out in openstack20:34
johnsomYes, very much in plan. It's just getting people that can work on it.20:34
spatel+120:34
johnsomYou would probably find this specification interesting: https://docs.openstack.org/octavia/latest/contributor/specs/version0.9/active-active-topology.html20:35
spatelThanks!20:36
spatelthat looks complicated :)20:36
johnsomYeah, not bad, but a lot of parts. I had started the work, but unfortunately my downstream focus changed.20:37
spatelAWS use DNS/CNAME for ELB right?20:38
spatelThis article looks interesting20:39
johnsomYeah, ELB is DNS based. AWS ALB is more like Octavia.20:40

spatelI download octavia-amphora from internet and looks like it comes with haproxy-1.8.x  i think i should create my own with 2.x version20:42
johnsomYeah, we don't ship pre-built images. We provide a command line tool that builds the image.20:42
johnsomNewer version of the tool will install 2.x20:43
spatelI think 2.x is the way to go20:43
johnsom2.x gives you multi-core support20:43
spatelYes that is what i need20:44
spatelDo you recommend to keep logs on amphora or ship it out to syslog?20:44
spatelnot sure how much disk space they will eat20:45
johnsomUse log offloading and disable writing logs in the amphora. It gives a good boost in performance20:45
spatel+120:46
johnsomYeah, it depends on the request rate. By default it writes a log line per request20:46
johnsomhttps://docs.openstack.org/octavia/latest/admin/log-offloading.html20:46
spatellet me read about that20:49

adebergI'd be curious to see the actual volume implied for our 800+ amphorae with varying workloads20:55
