Editor to share with you how to deploy OpenStack monitoring components Ceilometer and Folsom, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Before the project has been using the Folsom version of OpenStack for secondary development, there are no small changes to nova and other modules, so when the new version of OpenStack (Grizzly) is released, some new functional modules can not be quickly transplanted to the newly developed project. Since the system monitoring function of the previous version of OpenStack is relatively weak, kanyun + ganglia plus the simple monitoring feature provided by openstack has been used for system monitoring, which is quite a copycat. Therefore, after the G version has been released with the monitoring function module ceilometer, it needs to be combined with the original system. Here is the experience of deployment:

1. Download the ceilometer code of * from github

two。 To install mongodb, because ceilometer uses mongodb as the default data persistence database, you need to install mongodb first

Apt-get install mongodb

3. Add ceilometer users to keystone

Note: the added ceilometer account must belong to admin tenant, otherwise the instance monitoring information cannot be obtained, and this account is added to the ResellerAdmin role to facilitate the acquisition of swift monitoring information.

4. To install ceilometer, first look at the packages that the module depends on:

Vim ceilometer/requirements.txt d2to1 > = 0.2.10 pymongo > = 2.2 eventlet anyjson > = 0.2.4 Flask==0.9 pecan > = 0.2.0 stevedore > = 0.7 msgpack-python python-glanceclient python-novaclient > = 2.6.10 python-keystoneclient > = 0.2.3 python-swiftclient lxml requests > = 1.1 wsme > = 0.5b2 pyyaml oslo.config > = 1.1.0 happybase > = 0.4

This version of ceilometer uses the newly added oslo.config module in the G version of Openstack to complete the configuration file reading module.

In addition, the WebOb version is required to be above 1.2. check the F version Openstack using this library version 1.0.8, which is a big conflict, and found that many people reflect that this library is not compatible with the previous library. In my actual installation process, I also found that this library can not be used by python-novaclient, python-glanceclient and other libraries. So I used virtualenv to establish an isolated python environment to install and run ceilometer and related dependencies.
