Out of two colors, returns the color with the highest severity.

Constructor: new Hobbit('testname');

Constructor: new Hobbit({ test => 'testname', ttl => 60, ...});

Creates a new Hobbit object.

Common use cases

  my $bb = new Hobbit('sometest');
  my $bb = new Hobbit({ test      => 'testname',
                        color     => 'green',
                        hostname  => 'host.example.com',
                        text      => 'Test successful',
                        title     => 'Some Test',
                        ttl       => 60,
                        type      => 'status',
                        dont_moan => 1 });

Available parameters

color

The initial color of the test. (Default: "clear")

dont_moan

Disable moan() and croak() (see below). Needed if e.g. another used Perl module throws a lot of warnings but works fine otherwise, etc.

hostname

The hostname for which the test should report. (Default: $ENV{CLIENTHOSTNAME} || $ENV{MACHINEDOTS} || $ENV{MACHINE} || 'unknown')

test

The name of the test, i.e. the name of the column on the hobbit status web pages. (Mandatory)

text

Text which is prepended to generated report. (Default: the empty string)

title

The summary of the test. (Default: "$test OK" respectively "$test NOT ok")

ttl

How long the test result is valid before the test state is changed to purple by the xymon daemon if no newer test results have been received.

The default value is set on the xymon server and is 300 seconds by default.

Values without unit are interpreted as minutes. Valid units are h for hours, d for days, and w for weeks. No space between value and unit allowed.

type

Allows one to send messages of other types than "status", e.g. data, notify, disable, enable, etc.

May not yet work with all of these types properly. Please report bugs via the Debian Bug Tracking system.

Constructor: Hobbit::trends;

Constructor: Hobbit::trends ('hostname');

Creates a new Hobbit trends object. This is a shorthand for new Hobbit({ type = 'data', test = 'trends', hostname = $hostname, dont_moan => 1 });

Common use case

  my $trends = Hobbit::trends;
  $trends->print ("[$bb->{test},extralabel.rrd]\n");
  $trends->print ("DS:lambda:GAUGE:600:U:U $value\n");
  $trends->send;

add_color('somecolor')

Minutes that a sub test caused the given color state. Adjusts the overall resulting color accordingly.

print('some text')

Adds the given text to the end of the current report without changing the current color.

sprintf('format', args ...)

Like the print() method, but using sprintf() with format string and arguments.

color_print('somecolor', 'some text')

Adds the given text to the end of the current report and minutes that a sub test caused the given color state. Adjusts the overall resulting color accordingly.

color_line('somecolor', 'some text')

Adds the given text to the end of the current report and minutes that a sub test caused the given color state. Prepends that text with an accordingly colored Xymon icon and adjusts the overall resulting color accordingly.

graph('graphname')

Adds HTML for showing a graph. Xymon itself can only show a single graph per test (others can be added to the "trends" column). This method works around that limitation by manually linking to the graph CGI.

send()

Sends the report to the xymon server.

grep(tag)

Run a xymongrep (bbhostgrep) query and return an array reference of hashes with keys ip (string), hostname (string), and tags (array reference).

  my $list = Hobbit::grep('foobar');
  foreach my $host (@$list) {
    print "$host->{ip} $host->{hostname}\n";
  }

moan()

If the check issues a Perl warning, this warning is added to the report with color state "yellow".

Set dont_moan to 1 to disable this feature.

croak()

If the check issues a Perl error, this error is added to the report with color state "red".

Set dont_moan to 1 to disable this feature.
