Make sure the ‘Build-Requires’ Packages are coming from
Opencontrail PPA
https://launchpad.net/~opencontrail/+archive/ubuntu/ppa/+packages

In this case make sure librdkafka version is
https://launchpad.net/~opencontrail/+archive/ubuntu/ppa/+files/librdkafka-dev_0.9.4-0contrail0_amd64.deb

Re: [opencontrail-dev] cassandra server switchover

[Raj Reddy]

Is there any reason why you are using 2.21, better to be with newer releases.
we have multiple stable releases after that.

Hi Megh,

Thanks for the response.

Yes, netstat -anp shows thats collector connects to the another server.

Reg  TimedOutException  , Let me recheck my cassandra cluster 
configuration/setup.

Thanks

In 2.21 the architecture is different, collector will establish one connection 
to one cassandra server per generator. If that fails, it will retry the next 
server. This is evident from the collector logs. It seems that you are getting 
TimedOutException which suggests your single remaining cassandra node might be 
getting overloaded.

If you check using netstat -anp for contrail-collector pid you should be seeing 
connections to the 10.10.10.5 cassandra node.

Thanks

Hi Megh,

My scenario is very simple,

My setup : Devstack - Mitaka
   Contrail : 2.21.x

I have configured the cassandra cluster with two nodes, and specified those in 
the contrail-collector.conf file

cloud@contrail:/etc/cassandra$ cat /etc/contrail/contrail-collector.conf

[DEFAULT]
log_local = 1
log_level = SYS_DEBUG
cassandra_server_list = 10.10.10.5:9160 10.10.10.4:9160
hostname = contrail
hostip = 10.10.10.6

[DISCOVERY]
port = 5998
server = 10.10.10.6
cloud@contrail:/etc/cassandra$

Collector establishes the communication with 10.10.10.4, and works well.

I purposefully down the 10.10.10.4 cassandra server.  I expect contrail-control 
continue to work with 10.10.10.5 cassandra server.
But contrail-control keeps trying to connect  with 10.10.10.4 and fails to 
connect.


Note:
1. Collector establishes the communication with only one server(10.10.10.4)  
out of two mentioned.


collector logs are attached for debugging.

Thanks
suresh

Hi Suresh,
cassandra supports active/active or cluster consisting of multiple active nodes 
and hence we can provide list of IP addresses to contrail-collector. 
contrail-collector simultaneously connects to all the cassandra servers and 
will handle cassandra server failures.

Thanks

Hi,

In the contrail-collector config file, we can specify multiple cassandra 
servers.
What is the purpose of it ?


contrail-collecter.conf snippet

# IP address and port to be used to connect to cassandra.
# Multiple IP:port strings separated by space can be provided
# cassandra_server_list=127.0.0.1:9042

Does contrail support  server switchover, I  mean when the current server is 
not reachable, will it switch to the new server(mentioned in the config) ?

Thanks

Re: [opencontrail-dev] Issue with contrail 3.0

[Raj Reddy]

We would like to be as less dependent on third party websites as possible 
during build process..
So we keep them in github.com:Juniper/contrail-third-party-cache and pull it 
from there..

Sagar [Cced] is working on it and will submit a fix.

You may be missing some packages. Get the latest list from

I use centos 7.0 to build Contrail R3.0. The codes was pulled from the

 reported  the error :
could not find the cassandra.h. I use this host to build R2.2 successfully. I  
copy one cassandra.h from the github, but scons reported some other errors.

 Anyone could tell me that I miss some packages for build R3.0. If could proved

Re: [opencontrail-dev] why our own contrail 2.2 package is not same with the official contrail2.2 package

[Raj Reddy]

How are you building the RPMs?
If you use
tools/packages/rpm/contrail/contrail.spec
the RPMs should be the same..

Re: [opencontrail-dev] analytics-api not giving proper results when queried on another IP than 127.0.0.1

[Raj Reddy]

Hi Martin,

Our analytics design requires redis to be running locally (w/ no sentinel, no 
clustering)
on each of the analytics nodes. And as Pedro stated, we do not depend on redis 
being
persistent - data is recreated when we connect to redis.

 Sorry,

 Hallo Raj,
 
 no. We’re running Redis with Sentinel here, and access to Redis is possible 
 through an
 HAProxy load balancer that will ensure that nodes always land on the one 
 redis node that
 is currently the master of the sentinel cluster. I don’t see how scaling out 
 redis for purposes
 of performance and high availability would work in any other way. We’ll need 
 the analytics
 api to be fixed to allow to specify an arbitrary ip address to connect to 
 redis. Shall I fill a 
 bug in Launchpad?

 It appears we are relying on the fact that redis is listening on 0.0.0.0
 You can comment the redis.conf bindip parameter or change it to 0.0.0.0
