pynag - Online in the Cloud

PROGRAM:

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
