pynag man page

pynag <sub-command> [options] [arguments]

pynag is a command-line utility that can be used to view or change current nagios configuration.

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>]

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:

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.

Syntax:

SET <attr1=value1> [attr2=value2] [...]

Example:

pynag update SET address=127.0.0.1 WHERE host_name=localhost and object_type=host
