NAME

AFS::Command::BOS - OO API to the AFS bos command

SYNOPSIS

    use AFS::Command::BOS;

    my $bos = AFS::Command::BOS->new();

    my $bos = AFS::Command::BOS->new
      (
       command                  => $path_to_your_bos_binary,
      );

    my $bos = AFS::Command::BOS->new
      (
       localauth                => 1,
      );

DESCRIPTION

This module implements an OO API wrapper around the AFS 'bos' command. The supported methods depend on the version of the bos binary used, and are determined automagically.

METHODS -- Inherited

All of the following methods are inherited from the AFS::Command::Base class. See that documentation for details.

METHODS (with complex return values)

getdate

Arguments

The bos help string is:

    bos getdate: get dates for programs
    Usage: bos getdate -server <machine name> -file <files to check>+ [-dir <destination dir>]
                       [-cell <cell name>] [-noauth] [-localauth]

The corresponding method invocation looks like:

    my $result = $bos->getdate
      (
       # Required arguments
       server                   => $server,
       file                     => $file, # OR [ $file1, $file2, ... ]
       # Optional arguments
       dir                      => $dir,
       cell                     => $cell,
       noauth                   => 1,
       localauth                => 1,
      );
Return Values

This method returns an AFS::Object::BosServer object, which contains one or more generic AFS::Object, one for each file specified in the arguments.

    my $result = $bos->getdate
      (
       file                             => [ 'bosserver', 'vlserver', 'ptserver' ],
       cell                             => $cell,
      ) || die $bos->errors();

    foreach my $fileobj ( $result->getFiles() ) {
        my ($file,$date) = ($fileobj->file(),$fileobj->date());
        print "File $file has date $date\n";
    }

Each of these objects has the following attributes and methods:

AFS::Object::BosServer

This object is nothing more than a container for the generic objects for each file. It has several methods for extracting the file objects:

    Methods                     Returns
    -------                     -------
    getFileNames()              a list of filenames
    getFiles()                  a list of AFS::Object objects
    getFile($filename)          the AFS::Object object for $filename

AFS::Object

The following attributes should always be present:

    Attributes                  Values
    ----------                  ------
    file                        fully qualified pathname to the file
    date                        last modified timestamp on the file

The following attributes may be present, if there are .BAK or .OLD versions of the file.

    Attributes                  Values
    ----------                  ------
    bak                         last modified timestamp on the .BAK file
    old                         last modified timestamp on the .OLD file

getlog

Arguments

The bos help string is:

    bos getlog: examine log file
    Usage: bos getlog -server <machine name> -file <log file to examine>
                      [-cell <cell name>] [-noauth] [-localauth]

The corresponding method invocation looks like:

    my $result = $bos->getlog
      (
       # Required arguments
       server                   => $server,
       file                     => $file,
       # Optional arguments
       cell                     => $cell,
       noauth                   => 1,
       localauth                => 1,
       # Enhanced arguments
       redirect                 => $redirect,
      );

The 'redirect' argument is the name of a file to "redirect" the log file to. By default, 'bos getlog' dumps the contents of the requested file to stdout, which is not what you normally want in an application. The value of this argument is passed directly to IO::File->open().

If this argument is not specified, then the contents of the logfile are stashed in an attribute of the returned object.

Return Values

This method returns an AFS::Object::BosServer object, which contains one attribute.

    my $result = $bos->getlog
      (
       server                   => $server,
       file                     => "/usr/afs/logs/VolserLog",
       redirect                 => "/var/tmp/VolserLog.$$",
      ) || die $bos->errors();

    my $logfile = IO::File->new("</var/tmp/VolserLog.$$") ||
      die "Unable to open logfile: $ERRNO\n";

    while ( defined($_ = $logfile->getline()) ) {
        ....
    }

    # Alternately, the memory pig way:

    my $result = $bos->getlog
      (
       server                   => $server,
       file                     => "/usr/afs/logs/VolserLog",
      );

    foreach ( split(/\n+/,$result->log()) ) {
        ....
    }

The object has the following attribute:

AFS::Object::BosServer

    Attributes                  Values
    ----------                  ------
    log                         Contents of the logfile, or the redirect pathname

If redirect was given, then this attribute is simply same pathname. If redirect was not given, then the value of this attribute is the contents of the requested logfile, as a single (potentially huge) string.

NOTE: Since this method is usually invoked to retrieve one of the AFS logfiles, which can be enormous on heavily loaded servers that have not been restarted in a while, use of the redirect option is strongly encouraged. If not used, the memory allocated to store the logfile may be prohibitively large. Developer beware.

getrestart

Arguments

The bos help string is:

    bos getrestart: get restart times
    Usage: bos getrestart -server <machine name> [-cell <cell name>]
                          [-noauth] [-localauth]

The corresponding method invocation looks like:

    my $result = $bos->getrestart
      (
       # Required arguments
       server                   => $server,
       # Optional arguments
       cell                     => $cell,
       noauth                   => 1,
       localauth                => 1,
      );
Return Values

This method returns an AFS::Object::BosServer object, which contains two attributes.

    my $result = $bos->getrestart
      (
       server                   => $server,
       cell                     => $cell,
      ) || die $bos->errors();
    print "Binary restart time is " . $result->binaries() . "\n";
    print "Server restart time is " . $result->restart() . "\n";

The object has the following attributes:

AFS::Object::BosServer

    Attributes                  Values
    ----------                  ------

       # Optional arguments
       cell                     => $cell,
       noauth                   => 1,
