Package org.opennms.netmgt.config

Class CollectdConfigFactory

java.lang.Object

org.opennms.netmgt.config.CollectdConfigFactory

All Implemented Interfaces:

CollectdConfigFactory

public class CollectdConfigFactory
extends Object
implements CollectdConfigFactory

This is the singleton class used to load the configuration for the OpenNMS Collection Daemon from the collectd-configuration.xml file. A mapping of the configured URLs to the IP list they contain is built at init() time so as to avoid numerous file reads. Note: Users of this class should make sure the init() is called before calling any other method to ensure the config is loaded before accessing other convenience methods.

Method Detail

reload

public void reload()
            throws IOException

Reload the config from the default config file

Specified by:

reload in interface CollectdConfigFactory

Throws:

IOException - Thrown if the specified config file cannot be read/loaded

IOException - if any.

saveCurrent

public void saveCurrent()
                 throws IOException

Saves the current in-memory configuration to disk and reloads

Specified by:

saveCurrent in interface CollectdConfigFactory

Throws:

IOException - if any.

getCollectdConfig

public CollectdConfiguration getCollectdConfig()

getCollectdConfig

Specified by:

getCollectdConfig in interface CollectdConfigFactory

Returns:

a CollectdConfiguration object.

packageExists

public boolean packageExists(String name)

Returns true if collection package exists

Specified by:

packageExists in interface CollectdConfigFactory

Parameters:

name - The package name to check

Returns:

True if the package exists

getPackage

public Package getPackage(String name)

getPackage

Specified by:

getPackage in interface CollectdConfigFactory

Parameters:

name - a String object.

Returns:

a Package object.

domainExists

public boolean domainExists(String name)

Returns true if collection domain exists

Specified by:

domainExists in interface CollectdConfigFactory

Parameters:

name - The domain name to check

Returns:

True if the domain exists

isServiceCollectionEnabled

public boolean isServiceCollectionEnabled(OnmsMonitoredService service)

Returns true if the specified service's interface is included by at least one package which has the specified service and that service is enabled (set to "on").

Specified by:

isServiceCollectionEnabled in interface CollectdConfigFactory

Parameters:

service - OnmsMonitoredService to check

Returns:

true if Collectd config contains a package which includes the specified interface and has the specified service enabled.

isServiceCollectionEnabled

public boolean isServiceCollectionEnabled(OnmsIpInterface iface,
                                          String svcName)

Returns true if the specified interface is included by at least one package which has the specified service and that service is enabled (set to "on").

Specified by:

isServiceCollectionEnabled in interface CollectdConfigFactory

Parameters:

iface - OnmsIpInterface to lookup

svcName - The service name to lookup

Returns:

true if Collectd config contains a package which includes the specified interface and has the specified service enabled.

isServiceCollectionEnabled

public boolean isServiceCollectionEnabled(String ipAddr,
                                          String svcName)

Deprecated.

This function should take normal model objects instead of bare IP addresses and service names. Use isServiceCollectionEnabled(OnmsIpInterface, String) instead.

Returns true if the specified interface is included by at least one package which has the specified service and that service is enabled (set to "on").

Specified by:

isServiceCollectionEnabled in interface CollectdConfigFactory

Parameters:

ipAddr - IP address of the interface to lookup

svcName - The service name to lookup

Returns:

true if Collectd config contains a package which includes the specified interface and has the specified service enabled.

interfaceInFilter

public boolean interfaceInFilter(String iface,
                                 Package pkg)

Specified by:

interfaceInFilter in interface CollectdConfigFactory

interfaceInPackage

public boolean interfaceInPackage(String iface,
                                  Package pkg)

Deprecated.

This function should take normal model objects instead of bare IP addresses. Move this implementation into interfaceInPackage(OnmsIpInterface, Package).

This method is used to determine if the named interface is included in the passed package definition. If the interface belongs to the package then a value of true is returned. If the interface does not belong to the package a false value is returned. Note: Evaluation of the interface against a package filter will only work if the IP is already in the database.

Specified by:

interfaceInPackage in interface CollectdConfigFactory

Parameters:

iface - The interface to test against the package.

Returns:

True if the interface is included in the package, false otherwise.

interfaceInPackage

public boolean interfaceInPackage(OnmsIpInterface iface,
                                  Package pkg)

This method is used to determine if the named interface is included in the passed package definition. If the interface belongs to the package then a value of true is returned. If the interface does not belong to the package a false value is returned. Note: Evaluation of the interface against a package filter will only work if the IP is already in the database.

Specified by:

interfaceInPackage in interface CollectdConfigFactory

Parameters:

iface - The interface to test against the package.

Returns:

True if the interface is included in the package, false otherwise.
