Monitoring::Availability3pm
Calculate availability data from nagios / icinga and shinken logfiles.
Usage
use Monitoring::Availability;my $ma = Monitoring::Availability->new();
Overview
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.
- rpttimeperiod
-
report timeperiod. defines a timeperiod for this report. Will use 24x7 if not specified.
- assumeinitialstates
-
Assume the initial host/service state if none is found, default: yes
- assumestateretention
-
Assume state retention, default: yes
- assumestatesduringnotrunning
-
Assume state during times when the monitoring process is not running, default: yes
- includesoftstates
-
Include soft states in the calculation. Only hard states are used otherwise, default: no
- initialassumedhoststate
-
Assumed host state if none is found, default: unspecified
valid options are: unspecified, current, up, down and unreachable
- initialassumedservicestate
-
Assumed service state if none is found, default: unspecified
valid options are: unspecified, current, ok, warning, unknown and critical
- backtrack
-
Go back this amount of days to find initial states, default: 4
- showscheduleddowntime
-
Include downtimes in calculation, default: yes
- timeformat
-
Time format for the log output, default:
%s
- verbose
-
verbose mode
- breakdown
-
Breakdown availability into 'months', 'weeks', 'days', 'none'
adds additional 'breakdown' hash to each result with broken down results
Methods
calculate
calculate()
Calculate the availability
- start
-
Timestamp of start
- end
-
Timestamp of end
- log_string
-
String containing the logs
- log_file
-
File containing the logs
- log_dir
-
Directory containing *.log files
- log_livestatus
-
Array with logs from a livestatus query
a sample query could be:selectall_arrayref(GET logs...\nColumns: time type options, {Slice => 1})
- log_iterator
-
Iterator object for logentry objects. For example a L<MongoDB::Cursor> object.
- hosts
-
array with hostnames for which the report should be generated
- services
-
array with hashes of services for which the report should be generated. The array should look like this:
[{host => 'hostname', service => 'description'}, ...]
- initial_states
-
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
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.
