NAME

Monitoring::Availability - Calculate Availability Data from Nagios / Icinga and Shinken Logfiles.

SYNOPSIS

    use Monitoring::Availability;
    my $ma = Monitoring::Availability->new();

DESCRIPTION

This module calculates the availability for hosts/server from given logfiles. The Logfileformat is Nagios/Icinga only.

REPOSITORY

    Git: http://github.com/sni/Monitoring-Availability

CONSTRUCTOR

new ( [ARGS] )

Creates an "Monitoring::Availability" object. "new" takes at least the logs parameter. Arguments are in key-value pairs.

report timeperiod. defines a timeperiod for this report. Will use 24x7 if not specified.
Assume the initial host/service state if none is found, default: yes
Assume state retention, default: yes
Assume state during times when the monitoring process is not running, default: yes
Include soft states in the calculation. Only hard states are used otherwise, default: no
Assumed host state if none is found, default: unspecified

valid options are: unspecified, current, up, down and unreachable

Assumed service state if none is found, default: unspecified

valid options are: unspecified, current, ok, warning, unknown and critical

Go back this amount of days to find initial states, default: 4
Include downtimes in calculation, default: yes
Time format for the log output, default: %s
verbose mode
Breakdown availability into 'months', 'weeks', 'days', 'none'

adds additional 'breakdown' hash to each result with broken down results

METHODS

calculate

 calculate()

Calculate the availability

Timestamp of start
Timestamp of end
String containing the logs
File containing the logs
Directory containing *.log files
Array with logs from a livestatus query

 a sample query could be:
 selectall_arrayref(GET logs...\nColumns: time type options, {Slice => 1})
    
 Iterator object for logentry objects. For example a L<MongoDB::Cursor> object.
    
array with hostnames for which the report should be generated
array with hashes of services for which the report should be generated. The array should look like this:

 [{host => 'hostname', service => 'description'}, ...]
    
if you use the "current" option for initialassumedservicestate or initialassumedhoststate you have to provide the current states with a hash like this:

  {
    hosts => {
     'hostname' => 'ok',
     ...
    },
    services => {
     'hostname' => {
         'description' =>  'warning',
         ...
      }
    }
  }
    

valid values for hosts are: up, down and unreachable

valid values for services are: ok, warning, unknown and critical

get_condensed_logs

 get_condensed_logs()

returns an array of hashes with the condensed log used for this report

get_full_logs

 get_full_logs()

returns an array of hashes with the full log used for this report

BUGS

Please report any bugs or feature requests to <http://github.com/sni/Monitoring-Availability/issues>.

DEBUGING

You may enable the debug mode by setting MONITORING_AVAILABILITY_DEBUG environment variable. This will create a logfile: /tmp/Monitoring-Availability-Debug.log which gets overwritten with every calculation. You will need the Log4Perl module to create this logfile.
