PYNAG(1)

NAME
pynag - command line front for manipulating nagios configuration

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
