简介
osprofiler是专门针对OpenStack的性能调优工具,采集到的信息可以存入ceilometer、redis、mongodb、elasticsearch等后端,默认存储在ceilometer中。
安装
还是以devstack方式先安装个OpenStack出来,上个local.conf配置文件(性能信息存入ceilometer)
[[email protected] devstack]$ cat local.conf [[local|localrc]] # use trystack git mirror GIT_BASE=http://git.trystack.cn NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git SPICE_REPO= # enable panko, panko provides event storage for ceilometer now. enable_plugin panko http://git.trystack.cn/openstack/panko enable_plugin ceilometer http://git.trystack.cn/openstack/ceilometer enable_plugin osprofiler http://git.trystack.org/openstack/osprofiler master #CEILOMETER_BACKEND=mongodb RECLONE=no # add profiler topic CEILOMETER_NOTIFICATION_TOPICS=notifications,profiler # define osprofiler hmac keys OSPROFILER_HMAC_KEYS=swordfish,foxtrot,charlie enable_service ceilometer-api PANKO_BACKEND=mongodb [[post-config|$NOVA_CONF]] [profiler] enabled = True trace_sqlalchemy = True
安装过程,就不详细叙述了!
注意:devstack安装osprofiler的时候,会以pip install osprofiler的方式安装(可能有坑),需要pip uninstall osprofiler,
然后切换到osprofiler源码目录,执行python setup.py build && python setup.py install.
使用
# 使用上面定义好的OSPROFILER_HMAC_KEYS中的任意一个 [[email protected] devstack]$ nova --profile charlie boot --image 8e02a6be-511a-4904-a400-87f8d86a5862 --flavor 1 --nic net-id=cbfdd288-2357-4161-8180-f7d6bd001420 test1 /usr/lib/python2.7/site-packages/novaclient/client.py:278: UserWarning: The ‘tenant_id‘ argument is deprecated in Ocata and its use may result in errors in future releases.

生成html报告
[[email protected] devstack]$ osprofiler trace show --html 7c157a83-8608-45c2-9989-68da9a18906e --out /tmp/a.html
