# Our parsing of the nginx config files is very rudimentary.
# It'll work with lots of different configurations - but not every
# possible configuration.
#
# Patches are being accepted ;-)
#
# OCF parameters:
# OCF_RESKEY_configfile
# OCF_RESKEY_nginx
# OCF_RESKEY_port
# OCF_RESKEY_options
# OCF_RESKEY_status10regex
# OCF_RESKEY_status10url
# OCF_RESKEY_client
# OCF_RESKEY_testurl
# OCF_RESKEY_test20regex
# OCF_RESKEY_test20conffile
# OCF_RESKEY_test20name
# OCF_RESKEY_external_monitor30_cmd
#
#
# TO DO:
# More extensive tests of extended monitor actions
# Look at the --with-http_stub_status_module for validating
# the configuration? (or is that automatically done?)
# Checking could certainly result in better error
# messages.
# Allow for the fact that the config file and so on might all be
# on shared disks - this affects the validate-all option.

For this to be supported you must configure mod_status
and give it a server-status URL - or configure what URL
you wish to be monitored. You have to have installed
either curl or wget for this to work.

<resource-agent name="nginx">
<version>1.0</version>
<longdesc lang="en">
This is the resource agent for the Nginx web/proxy server.
This resource agent does not monitor POP or IMAP servers, as
we don't know how to determine meaningful status for them.
The start operation ends with a loop in which monitor is
repeatedly called to make sure that the server started and that
it is operational. Hence, if the monitor operation does not
succeed within the start operation timeout, the nginx resource
will end with an error status.
The default monitor operation will verify that nginx is running.
The level 10 monitor operation by default will try and fetch the /nginx_status
page - which is commented out in sample nginx configurations.
Make sure that the /nginx_status page works and that the access
is restricted to localhost (address 127.0.0.1) plus whatever
places _outside the cluster_ you want to monitor the server from.
See the status10url and status10regex attributes for more details.
The level 20 monitor operation will perform a more complex set of tests
from a configuration file.
The level 30 monitor operation will run an external command to perform
an arbitrary monitoring operation.

<longdesc lang="en">
The URL to monitor (the nginx server status page by default) when given a level 10 monitor operation.
If left unspecified, it will be inferred from
the nginx configuration file, or defaulted to /nginx_status.
If you set this, make sure that it succeeds *only* from the
localhost (127.0.0.1) and no other cluster nodes.
Otherwise, the cluster software may complain
about it being active on multiple nodes.
