NAME

SYNOPSIS
--------
pynag <sub-command> [options] [arguments]
DESCRIPTION
-----------
pynag is a command-line utility that can be used to view or change current
nagios configuration.
sub-commands
------------
*list*
print to screen nagios configuration objects as specified by a WHERE
clause
| pynag list [attribute1] [attribute2] [WHERE ...]
*update*
modify specific attributes of nagios objects as specified by a WHERE
and SET clause
| pynag update set attr1=value WHERE attr=value and attr=value
*delete*
Delete objects from nagios configuration as specified by a WHERE clause
| pynag delete delete <WHERE ...>
*add*
Add a new object definition
| pynag add <object_type> <attr1=value1> [attr2=value2]
*copy*
Copy objects, specifiying which attributes to change
| pynag copy <WHERE ...> <SET attr1=value1 [attr2=value2] ...>
*execute*
Executes the currently configured check command for a host or a service
| pynag execute <host_name> [service_description]
*config*
modify values in main nagios configuration file (nagios.cfg)
| pynag config [--set <attribute=value>] [--old_value=attribute]
| pynag config [--append <attribute=value>] [--old_value=attribute]
| pynag config [--remove <attribute>] [--old_value=attribute]
| pynag config [--get <attribute>]
WHERE statements
----------------
Some Subcommands use WHERE statements to filter which objects to work
with. Where has certain similarity with SQL syntax.
Syntax:
| WHERE <attr=value> [AND attr=value] [OR attr=value] \
| [another where statement]
where "attr" is any nagios attribute (i.e. host_name or
service_description).
Example:
| pynag list WHERE host_name=localhost and object_type=service
| pynag list WHERE object_type=host or object_type=service
Any search attributes have the same syntax as the pynag filter. For example
these work just fine:
| pynag list WHERE host_name__contains=production
| pynag list WHERE host_name__startswith=prod
| pynag list WHERE host_name__notcontains=test
| pynag list host_name address WHERE address__exists=True
| pynag list host_name WHERE register__isnot=0
The pynag filter supports few parameters that are not just attributes.
Example:
* filename -- The filename which the object belongs
* id -- pynag unique identifier for the object
* effective_command_line -- command which nagios will execute
Of course these can be combined with the pynag filter syntax:
| pynag list where filename__startswith=/etc/nagios/conf.d/
| pynag list host_name service_description effective_command_line
For detailed description of the filter see pydoc for
pynag.Model.ObjectDefintion.filter()
SET statements
--------------
Subcommands that use SET statements (like update or copy) use them a list of
attributes change for a specific object.
Syntax:
| SET <attr1=value1> [attr2=value2] [...]
Example:
| pynag update SET address=127.0.0.1 WHERE host_name=localhost and object_type=host
EXAMPLES
--------
List all services that have "myhost" as a host_name
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| pynag list host_name service_description WHERE host_name=myhost and object_type=service
Set check_period to 24x7 on all services that belong to host "myhost"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| pynag update set check_period=24x7 WHERE host_name=myhost
list examples
^^^^^^^^^^^^^
| pynag list host_name address WHERE object_type=host
| pynag list host_name service_description WHERE host_name=examplehost and object_type=service
update examples
^^^^^^^^^^^^^^^
| pynag update SET host_name=newhostname WHERE host_name=oldhostname
| pynag update SET address=127.0.0.1 WHERE host_name='examplehost.example.com' and object_type=host
copy examples
^^^^^^^^^^^^^
| pynag copy SET host_name=newhostname WHERE host_name=oldhostname
| pynag copy SET address=127.0.0.1 WHERE host_name='examplehost.example.com' and object_type=host
add examples
^^^^^^^^^^^^
| pynag add host host_name=examplehost use=generic-host address=127.0.0.1
| pynag add service service_description="Test Service" use="check_nrpe" host_name="localhost"
delete examples
^^^^^^^^^^^^^^^
| pynag delete where object_type=service and host_name='mydeprecated_host'
| pynag delete where filename__startswith='/etc/nagios/myoldhosts'
execute examples
^^^^^^^^^^^^^^^^
| pynag execute localhost
| pynag execute localhost "Disk Space
