Enabling OSProfiler using DevStack
|
|
==================================
|
|
|
|
This directory contains the files necessary to run OpenStack with enabled
|
|
OSProfiler in DevStack.
|
|
|
|
OSProfiler can send trace data into different collectors. There are 2 parameters
|
|
that control this:
|
|
|
|
* ``OSPROFILER_COLLECTOR`` specifies which collector to install in DevStack.
|
|
By default OSProfiler plugin does not install anything, thus default
|
|
messaging driver will be used.
|
|
|
|
Possible values:
|
|
|
|
* ``<empty>`` - default messaging driver is used
|
|
* ``redis`` - Redis is installed
|
|
|
|
The default value of ``OSPROFILER_CONNECTION_STRING`` is set automatically
|
|
depending on ``OSPROFILER_COLLECTOR`` value.
|
|
|
|
* ``OSPROFILER_CONNECTION_STRING`` specifies which driver is used by OSProfiler.
|
|
|
|
Possible values:
|
|
|
|
* ``messaging://`` - use messaging as trace collector (with the transport configured by oslo.messaging)
|
|
* ``redis://[:password]@host[:port][/db]`` - use Redis as trace storage
|
|
* ``elasticsearch://host:port`` - use Elasticsearch as trace storage
|
|
* ``mongodb://host:port`` - use MongoDB as trace storage
|
|
* ``loginsight://username:password@host`` - use LogInsight as trace collector/storage
|
|
|
|
|
|
To configure DevStack and enable OSProfiler edit ``${DEVSTACK_DIR}/local.conf``
|
|
file and add the following to ``[[local|localrc]]`` section:
|
|
|
|
* to use Redis collector::
|
|
|
|
enable_plugin osprofiler https://git.openstack.org/openstack/osprofiler master
|
|
OSPROFILER_COLLECTOR=redis
|
|
|
|
OSProfiler plugin will install Redis and configure OSProfiler to use Redis driver
|
|
|
|
* to use specified driver::
|
|
|
|
enable_plugin osprofiler https://git.openstack.org/openstack/osprofiler master
|
|
OSPROFILER_CONNECTION_STRING=<connection string value>
|
|
|
|
the driver is chosen depending on the value of
|
|
``OSPROFILER_CONNECTION_STRING`` variable (refer to the next section for
|
|
details)
|
|
|
|
|
|
Run DevStack as normal::
|
|
|
|
$ ./stack.sh
|
|
|
|
|
|
Config variables
|
|
----------------
|
|
|
|
**OSPROFILER_HMAC_KEYS** - a set of HMAC secrets, that are used for triggering
|
|
of profiling in OpenStack services: only the requests that specify one of these
|
|
keys in HTTP headers will be profiled. E.g. multiple secrets are specified as
|
|
a comma-separated list of string values::
|
|
|
|
OSPROFILER_HMAC_KEYS=swordfish,foxtrot,charlie
|
|
|
|
**OSPROFILER_CONNECTION_STRING** - connection string to identify the driver.
|
|
Default value is ``messaging://`` refers to messaging driver. For a full
|
|
list of drivers please refer to
|
|
``http://git.openstack.org/cgit/openstack/osprofiler/tree/osprofiler/drivers``.
|
|
Example: enable ElasticSearch driver with the server running on localhost::
|
|
|
|
OSPROFILER_CONNECTION_STRING=elasticsearch://127.0.0.1:9200
|
|
|
|
**OSPROFILER_COLLECTOR** - controls which collector to install into DevStack.
|
|
The driver is then chosen automatically based on the collector. Empty value assumes
|
|
that the default messaging driver is used.
|
|
Example: enable Redis collector::
|
|
|
|
OSPROFILER_COLLECTOR=redis
|
