pynag <sub-command> [options] [arguments]
pynag is a command-line utility that can be used to view or change current nagios configuration.
print to screen nagios configuration objects as specified by a WHERE clause
pynag list [attribute1] [attribute2] [WHERE ...]
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 objects from nagios configuration as specified by a WHERE clause
pynag delete delete <WHERE ...>
Add a new object definition
pynag add <object_type> <attr1=value1> [attr2=value2]
Copy objects, specifiying which attributes to change
pynag copy <WHERE ...> <SET attr1=value1 [attr2=value2] ...>
Executes the currently configured check command for a host or a service
pynag execute <host_name> [service_description]
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>]
Some Subcommands use WHERE statements to filter which objects to work with. Where has certain similarity with SQL 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).
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.
- 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()
Subcommands that use SET statements (like update or copy) use them a list of attributes change for a specific object.
SET <attr1=value1> [attr2=value2] [...]
pynag update SET address=127.0.0.1 WHERE host_name=localhost and object_type=host
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
pynag list host_name address WHERE object_type=host pynag list host_name service_description WHERE host_name=examplehost and object_type=service
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
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
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"
pynag delete where object_type=service and host_name='mydeprecated_host' pynag delete where filename__startswith='/etc/nagios/myoldhosts'
pynag execute localhost pynag execute localhost "Disk Space
