/**
* This class provides a tool that can be used to search an LDAP directory
* server repeatedly using multiple threads, and then modify each entry
* returned by that server. It can help provide an estimate of the combined
* search and modify performance that a directory server is able to achieve.
* Either or both of the base DN and the search filter may be a value pattern as
* described in the {@link ValuePattern} class. This makes it possible to
* search over a range of entries rather than repeatedly performing searches
* with the same base DN and filter.
*
* Some of the APIs demonstrated by this example include:
*
*
Argument Parsing (from the {@code com.unboundid.util.args}
* package)
*
LDAP Command-Line Tool (from the {@code com.unboundid.util}
* package)
*
LDAP Communication (from the {@code com.unboundid.ldap.sdk}
* package)
*
Value Patterns (from the {@code com.unboundid.util} package)
*
*
* All of the necessary information is provided using command line arguments.
* Supported arguments include those allowed by the {@link LDAPCommandLineTool}
* class, as well as the following additional arguments:
*
*
"-b {baseDN}" or "--baseDN {baseDN}" -- specifies the base DN to use
* for the searches. This must be provided. It may be a simple DN, or it
* may be a value pattern to express a range of base DNs.
*
"-s {scope}" or "--scope {scope}" -- specifies the scope to use for the
* search. The scope value should be one of "base", "one", "sub", or
* "subord". If this isn't specified, then a scope of "sub" will be
* used.
*
"-f {filter}" or "--filter {filter}" -- specifies the filter to use for
* the searches. This must be provided. It may be a simple filter, or it
* may be a value pattern to express a range of filters.
*
"-A {name}" or "--attribute {name}" -- specifies the name of an
* attribute that should be included in entries returned from the server.
* If this is not provided, then all user attributes will be requested.
* This may include special tokens that the server may interpret, like
* "1.1" to indicate that no attributes should be returned, "*", for all
* user attributes, or "+" for all operational attributes. Multiple
* attributes may be requested with multiple instances of this
* argument.
*
"-m {name}" or "--modifyAttribute {name}" -- specifies the name of the
* attribute to modify. Multiple attributes may be modified by providing
* multiple instances of this argument. At least one attribute must be
* provided.
*
"-l {num}" or "--valueLength {num}" -- specifies the length in bytes to
* use for the values of the target attributes to modify. If this is not
* provided, then a default length of 10 bytes will be used.
*
"-C {chars}" or "--characterSet {chars}" -- specifies the set of
* characters that will be used to generate the values to use for the
* target attributes to modify. It should only include ASCII characters.
* Values will be generated from randomly-selected characters from this
* set. If this is not provided, then a default set of lowercase
* alphabetic characters will be used.
*
"-t {num}" or "--numThreads {num}" -- specifies the number of
* concurrent threads to use when performing the searches. If this is not
* provided, then a default of one thread will be used.
*
"-i {sec}" or "--intervalDuration {sec}" -- specifies the length of
* time in seconds between lines out output. If this is not provided,
* then a default interval duration of five seconds will be used.
*
"-I {num}" or "--numIntervals {num}" -- specifies the maximum number of
* intervals for which to run. If this is not provided, then it will
* run forever.
*
"--iterationsBeforeReconnect {num}" -- specifies the number of search
* iterations that should be performed on a connection before that
* connection is closed and replaced with a newly-established (and
* authenticated, if appropriate) connection.
*
"-r {ops-per-second}" or "--ratePerSecond {ops-per-second}" --
* specifies the target number of operations to perform per second. Each
* search and modify operation will be counted separately for this
* purpose, so if a value of 1 is specified and a search returns two
* entries, then a total of three seconds will be required (one for the
* search and one for the modify for each entry). It is still necessary
* to specify a sufficient number of threads for achieving this rate. If
* this option is not provided, then the tool will run at the maximum rate
* for the specified number of threads.
*
"--variableRateData {path}" -- specifies the path to a file containing
* information needed to allow the tool to vary the target rate over time.
* If this option is not provided, then the tool will either use a fixed
* target rate as specified by the "--ratePerSecond" argument, or it will
* run at the maximum rate.
*
"--generateSampleRateFile {path}" -- specifies the path to a file to
* which sample data will be written illustrating and describing the
* format of the file expected to be used in conjunction with the
* "--variableRateData" argument.
*
"--warmUpIntervals {num}" -- specifies the number of intervals to
* complete before beginning overall statistics collection.
*
"--timestampFormat {format}" -- specifies the format to use for
* timestamps included before each output line. The format may be one of
* "none" (for no timestamps), "with-date" (to include both the date and
* the time), or "without-date" (to include only time time).
*
"-Y {authzID}" or "--proxyAs {authzID}" -- Use the proxied
* authorization v2 control to request that the operations be processed
* using an alternate authorization identity. In this case, the bind DN
* should be that of a user that has permission to use this control. The
* authorization identity may be a value pattern.
*
"--suppressErrorResultCodes" -- Indicates that information about the
* result codes for failed operations should not be displayed.
*
"-c" or "--csv" -- Generate output in CSV format rather than a
* display-friendly format.
*
