簡介html

osprofiler是專門針對OpenStack的性能調優工具，採集到的信息能夠存入ceilometer、redis、mongodb、elasticsearch等後端，默認存儲在ceilometer中。python

安裝git

仍是以devstack方式先安裝個OpenStack出來，上個local.conf配置文件（性能信息存入ceilometer）redis

[stack@yao-devstack2 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 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

安裝過程，就不詳細敘述了！sql

注意：devstack安裝osprofiler的時候，會以pip install osprofiler的方式安裝（可能有坑），須要pip uninstall osprofiler，mongodb

而後切換到osprofiler源碼目錄，執行python setup.py build && python setup.py install.後端

使用api

# 使用上面定義好的OSPROFILER_HMAC_KEYS中的任意一個
