Re: [Openstack] swift recon query

[pragya jain]

Thanks Drudy Gerry for answering my queries.

But when I use curl command for recon, I get the following results:

root@swift-VirtualBox:~# curl -i http://127.0.0.1:6000/recon/mounted
curl: (7) couldn't connect to host

I don't understand where is the problem. Please help.

Thanks

Re: [Openstack] No VNC configuration in Havana

[Narayanan, Krishnaprasad]

I made the configuration changes that you specified at the controller and 
compute nodes but unfortunately it does not work. Are there any other 
configurations required?
In Internet explorer, I am able to see the error message where as in Firefox, I 
could not see anything. Does VNC appear in Firefox?

If you start from scratch I would certainly run the latest version.
Quite a few bug fixes in 2013.2.2:
https://wiki.openstack.org/wiki/ReleaseNotes/2013.2.2

There are reasons to stick to an older version though.
(e.g. it currently works, there is nothing in the release notes we need, so 
lets not break it ;)

Re: [Openstack] No VNC configuration in Havana

[Narayanan, Krishnaprasad]

Hi Jitendra,

The nova.conf in the controller node does not have any flags related to VNC.

In the compute node, I have the following flags defined in nova.conf

a)  novncproxy_port=6080

b)  novncproxy_host=

c)   vnc_console_proxy_url=http://:6080/vnc_auto.html

d)  novncproxy_base_url=http:// :6080/vnc_auto.html

e)  vncserver_proxyclient_address=
#vncserver_listen=

f)   vncserver_listen=0.0.0.0

g)  vncserver_enabled=true

Can I know is this correct?

Regards,
Krishnaprasad

Re: [Openstack] query about Statsd

[Anne Gentle]

Have you referred to this document?
http://docs.openstack.org/grizzly/openstack-object-storage/admin/content/ch_introduction-to-openstack-object-storage-monitoring.html

Answers below based on that circa-April-2013 document, might need updates.

yes, swift-informant sits in the proxy server's pipeline and after each

 server

   -

   A counter increment for a metric like obj.GET.200 or cont.PUT.404.
   -

   Timing data for a metric like acct.GET.200 or obj.GET.200. [The README
   says the metrics will look likeduration.acct.GET.200, but I don't see
   the "duration" in the code. I'm not sure what Etsy's server does, but our
   StatsD server turns timing metrics into 5 derivative metrics with new
   segments appended, so it probably works as coded. The first metric above
   would turn into acct.GET.200.lower, acct.GET.200.upper, acct.GET.200.mean
   ,acct.GET.200.upper_90, and acct.GET.200.count]
   -

   A counter increase by the bytes transferred for a metric like
   tfer.obj.PUT.201.

If you start from scratch I would certainly run the latest version.
Quite a few bug fixes in 2013.2.2:
https://wiki.openstack.org/wiki/ReleaseNotes/2013.2.2

There are reasons to stick to an older version though.
(e.g. it currently works, there is nothing in the release notes we need, so 
lets not break it ;)

Robert van Leeuwen

Hi,

I also noticed that Openstack can be pretty picky about versions, at least with 
2013.2.XXX.
Make sure the controller and compute nodes run the exact same versions.

The python neutron packages on the compute nodes also need to be the correct 
version.
Best would be to have just one version in your local repositorie or use 
puppet/chef/whatever ensure => version for this.

Cheers,
Robert van Leeuwen

Re: [Openstack] [Horizon] external network should not be mapped

[Heiko Krämer]

Hi Akihiro,

yes you'r absolutely right but i needed to shared this network for
visibility for all. This is a requirement for such clients to
communicate with the API because they need a network ID for public net.
Such clients checks if the id exists but doesn't if the pub net isn't
shared.

In addition if my external network is no marked as shared, sometimes (i
think if the cache of horizon will refreshed) a Cloud member can't
associate via Horizon new floating ip's because there is no public
network present.


So i think some operators have other examples if they have production
systems and the question still exists, why should we not filter all
external_network:True of the instance launch form ?


Cheers and thanks
Heiko

[Openstack] difference between metrics to statsd and metrics provided by swift recon middleware

[pragya jain]

hello all,
according to the documents, statsd server collects the following metrics about 
account-auditor:
Metric Name Description account-auditor.errors Count of audit runs (across all 
account databases) which caught an Exception. account-auditor.passes Count of 
individual account databases which passed audit. account-auditor.failures Count 
of individual account databases which failed audit. account-auditor.timing 
Timing data for individual account database audits.
and, swift recon middleware provides following information about 
account-auditor:  account_auditor_pass_completed  account_audits_passed  
account_audits_failed  account_audits_since
please somebody help me to understand what is the similarity and what is the 
difference between the metrics collected by statsd server and metrics provided 
by swift recon middleware.
Thanks

But I am able to boot up an instance successfully from command line. The above

Any thoughts ?
