How to expand the custom function in OpenStack, for this question, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

Text code

[pipeline:openstackapi11] pipeline = faultwrap authtoken keystonecontext ratelimit audit extensions osapiapp11 [filter:audit] paste.filter_factory = nova.api.openstack.audit:AuditMiddleware.factory

Then we write a Middleware:

Python code

Import time

From nova import log as logging

From nova import wsgi as base_wsgi

From nova.api.openstack import wsgi

LOG = logging.getLogger ('nova.api.audit')

Class AuditMiddleware (base_wsgi.Middleware):

"store POST/PUT/DELETE api request for audit."

Def _ _ init__ (self, application, audit_methods='POST,PUT,DELETE'):

Base_wsgi.Middleware.__init__ (self, application)

Self._audit_methods = audit_methods.split (",")

Def process_request (self, req):

Self._need_audit = req.method in self._audit_methods

If self._need_audit:

Self._request = req

Self._requested_at = time.time ()

Def process_response (self, response):

If self._need_audit and response.status_int > = 200and response.status_int < 300:

Self._store_log (response)

Return response

Def _ store_log (self, response):

Req = self._request

LOG.info ("tenant:% s, user:% s,% s:% s, at:% s"

Req.headers.get ('Xmurf Tenantals,' admin')

Req.headers.get ('Xmuri user,' admin')

Req.method

Req.path_info

Self._requested_at)

Restart the nova-api process, then do something on dashboard, and we can see the following information in the log file:

Text code

Tenant: 1, user: admin, POST: / 1/os-security-group-rules, at: 1326352441.16 tenant: 1, user: admin, DELETE: / 1/servers/32, at: 1326353021.58

All non-GET requests are recorded by default. If you do not want to record PUT requests (PUT corresponding to update), change it in the configuration file:

Text code

[filter:audit] this is the answer to audit_methods=POST,DELETE 's question on how to extend the custom function in OpenStack. I hope the above content can be of some help to you.
