RutujaHey! @vkmc.. Could you please share the config file, I'm done with the mongod installation14:03
vkmcRutuja, sure14:03
*** elmiko has joined #openstack-zaqar14:03
vkmcRutuja, http://paste.openstack.org/show/474852/14:04
vkmccreate a local.conf file under devstack/14:04
vkmcwith that content14:04
elmikoflaper87: ping14:05
Rutujaok!14:05
vkmcelmiko, flaper87 will be away for a couple of days IIRC14:10
elmikovkmc: ah, thanks. maybe you can help me out =)14:11
vkmcelmiko, sure, tell me14:11
elmikoi'm working on a test app that will distribute logs in real-time through zaqar to some receivers14:11
vkmcneat14:11
elmikoand i'm curious about how the messages get consumed from the zaqar queue14:12
elmikobasically, i want to make sure that 2 receivers don't read the same message. is that possible?14:12
Rutujahey done!14:13
vkmcRutuja, cool, run ./stack.sh and wait for the script to finish14:13
vkmcelmiko, you would like to have destructive reads that is (one receiver reads it, then its deleted from the queue)14:14
elmikovkmc: yea, basically14:15
vkmcelmiko, so right now we delegate the deletion to the clients14:16
RutujaIts throwing an error [ERROR] ./stack.sh:175 If you wish to run this script anyway run with FORCE=yes14:16
Rutuja/home/rutuja/devstack/functions-common: line 191: /opt/stack/logs/error.log: No such file or directory14:16
elmikovkmc: ok, so depending on the time it takes to delete the message from a client it's possible we could get double reads?14:16
vkmcelmiko, I think so, yes14:17
elmikovkmc: cool, i can work with that. thanks!14:17
vkmcelmiko, np!14:17
vkmcnow we have a new feature that allows you to specify flavors to the queue14:18
vkmcmaybe in a near future we can implement something like "destructive-reads" flavor and have queues that behave that way14:18
elmikothat would be cool14:18
vkmcflaper87, flwang ^ for later discussions :D14:19
vkmcyeah!14:19
thervevkmc, Isn't that what pop does?14:19
vkmcRutuja, remove everything you have under /opt/stack14:19
vkmctherve, eeeer, good question14:19
elmikoit may not be useful for every case, but i'd like to deploy something where we might have several nodes attempting to read a queue and then send the data on to an analytics app. so i want to make sure we don't send the same data twice.14:19
vkmcelmiko, you can use pop, that will retrieve and delete14:21
vkmcthanks therve14:21
vkmctherve, do you remember which order messages are retrieved in that case?14:21
elmikovkmc, therve: great, i guess i need to dig into the docs a little more ;)14:22
vkmcelmiko, no worries, I totally forgot about pop myself14:22
thervevkmc, Insertion one I guess?14:23
RutujaI'm not being able to locate opt in the devstack folder.. However, 2 stack files are visible, one has .sh extension14:23
vkmcRutuja, /opt is not under devstack/, its under a different location in your filesystem14:23
vkmccd /opt/stack from where you are should do the trick14:23
vkmctherve, I'll test that and document it... that's missing from the api reference14:24

akanksha_vkmc, I have an error on running devstack where it says it cant connect to mongodb server.  I checked mongodb logs and the server keeps shutting down as soon as it starts saying Wed Sep 30 23:11:13.358 [initandlisten] need to upgrade database zaqar_mgmt with pdfile version 4.21, new version: 4.517:48
akanksha_Wed Sep 30 23:11:13.358 [initandlisten]  Not upgrading, exiting17:48
akanksha_Wed Sep 30 23:11:13.358 [initandlisten]  run --upgrade to upgrade dbs, then start again17:48

akanksha_Wed Sep 30 23:11:13.358 dbexit:17:48
akanksha_Wed S17:48
vkmcakanksha_, please use http://paste.openstack.org for pastes17:49
vkmchaven't seen that error before17:49
vkmcakanksha_, is it a clean environment or is the previous one in which you already had zaqar installed?17:49
akanksha_in the previous one zaqar was running fine17:50
akanksha_I rebooted did unstack.sh and clean.sh And then tried to run stack.sh again17:50
vkmcakanksha_, but you installed zaqar manually... or how so?17:51
akanksha_I have both. I have a devstack installation where I have zaqar. And I have done it the virtual env way as well.17:51
vkmcbut its using the same mongodb instance17:53
akanksha_No. They are in separate machines17:53
vkmcakanksha_, ok, not sure what's going on with that mongodb output17:54
vkmctry purging it17:54
vkmcand restarting it17:54
akanksha_ purge mongodb ? Alright doing that.17:55
akanksha_vkmc, Meanwhile I was trying out the examples in python-zaqarclient repo. This one gives me errors https://github.com/openstack/python-zaqarclient/blob/master/examples/simple.py. The errors are : http://paste.openstack.org/show/474901/. I am not sure if this is a bug in the example code or some error in my installation.17:59
