All Implemented Interfaces:

@NotMutable
 @ThreadSafety(level=NOT_THREADSAFE)
public final class SummarizeAccessLog
extends CommandLineTool
implements java.io.Serializable

This class provides a tool that may be used to read and summarize the contents of one or more access log files from Ping Identity, UnboundID and Nokia/Alcatel-Lucent 8661 server products.

NOTE: This class, and other classes within the com.unboundid.ldap.sdk.unboundidds package structure, are only supported for use against Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.

Information that will be reported includes:

• The total length of time covered by the log files.
• The number of connections established and disconnected, the addresses of the most commonly-connecting clients, and the average rate of connects and disconnects per second.
• The number of operations processed, overall and by operation type, and the average rate of operations per second.
• The average duration for operations processed, overall and by operation type.
• A breakdown of operation processing times into a number of predefined categories, ranging from less than one millisecond to over one minute.
• A breakdown of the most common result codes for each type of operation and their relative frequencies.
• The most common types of extended requests processed and their relative frequencies.
• The number of unindexed search operations processed and the most common types of filters used in unindexed searches.
• A breakdown of the relative frequencies for each type of search scope.
• The most common types of search filters used for search operations and their relative frequencies.

It is designed to work with access log files using either the default log format with separate request and response messages, as well as log files in which the request and response details have been combined on the same line. The log files to be processed should be provided as command-line arguments.

The APIs demonstrated by this example include:

• Access log parsing (from the com.unboundid.ldap.sdk.unboundidds.logs package)
• Argument parsing (from the com.unboundid.util.args package)

supportsInteractiveMode

public boolean supportsInteractiveMode()

Indicates whether this tool should provide support for an interactive mode, in which the tool offers a mode in which the arguments can be provided in a text-driven menu rather than requiring them to be given on the command line. If interactive mode is supported, it may be invoked using the "--interactive" argument. Alternately, if interactive mode is supported and defaultsToInteractiveMode() returns true, then interactive mode may be invoked by simply launching the tool without any arguments.

Overrides:

supportsInteractiveMode in class CommandLineTool

Returns:

true if this tool supports interactive mode, or false if not.

defaultsToInteractiveMode

public boolean defaultsToInteractiveMode()

Indicates whether this tool defaults to launching in interactive mode if the tool is invoked without any command-line arguments. This will only be used if supportsInteractiveMode() returns true.

Overrides:

defaultsToInteractiveMode in class CommandLineTool

Returns:

true if this tool defaults to using interactive mode if launched without any command-line arguments, or false if not.

supportsOutputFile

protected boolean supportsOutputFile()

Indicates whether this tool should provide arguments for redirecting output to a file. If this method returns true, then the tool will offer an "--outputFile" argument that will specify the path to a file to which all standard output and standard error content will be written, and it will also offer a "--teeToStandardOut" argument that can only be used if the "--outputFile" argument is present and will cause all output to be written to both the specified output file and to standard output.

Overrides:

supportsOutputFile in class CommandLineTool

Returns:

true if this tool should provide arguments for redirecting output to a file, or false if not.

supportsPropertiesFile

public boolean supportsPropertiesFile()

Indicates whether this tool supports the use of a properties file for specifying default values for arguments that aren't specified on the command line.

Overrides:

supportsPropertiesFile in class CommandLineTool

Returns:

true if this tool supports the use of a properties file for specifying default values for arguments that aren't specified on the command line, or false if not.

supportsDebugLogging

protected boolean supportsDebugLogging()

Indicates whether this tool supports the ability to generate a debug log file. If this method returns true, then the tool will expose additional arguments that can control debug logging.

Overrides:

supportsDebugLogging in class CommandLineTool

Returns:

true if this tool supports the ability to generate a debug log file, or false if not.

addToolArguments

public void addToolArguments(@NotNull
                             ArgumentParser parser)
                      throws ArgumentException

Adds the command-line arguments supported for use with this tool to the provided argument parser. The tool may need to retain references to the arguments (and/or the argument parser, if trailing arguments are allowed) to it in order to obtain their values for use in later processing.

Specified by:

addToolArguments in class CommandLineTool

Parameters:

parser - The argument parser to which the arguments are to be added.

Throws:

ArgumentException - If a problem occurs while adding any of the tool-specific arguments to the provided argument parser.

doExtendedArgumentValidation

public void doExtendedArgumentValidation()
                                  throws ArgumentException

Performs any necessary processing that should be done to ensure that the provided set of command-line arguments were valid. This method will be called after the basic argument parsing has been performed and immediately before the doToolProcessing() method is invoked.

Overrides:

doExtendedArgumentValidation in class CommandLineTool

Throws:

ArgumentException - If there was a problem with the command-line arguments provided to this program.

doToolProcessing

@NotNull
public ResultCode doToolProcessing()

Performs the core set of processing for this tool.

Specified by:

doToolProcessing in class CommandLineTool

Returns:

A result code that indicates whether the processing completed successfully.

getExampleUsages

@NotNull
public java.util.LinkedHashMap<java.lang.String[],java.lang.String> getExampleUsages()

Retrieves a set of information that may be used to generate example usage information. Each element in the returned map should consist of a map between an example set of arguments and a string that describes the behavior of the tool when invoked with that set of arguments.

Overrides:

getExampleUsages in class CommandLineTool

Returns:

A set of information that may be used to generate example usage information. It may be null or empty if no example usage information is available.
