NAME

Examples covering the Zenoss JSON API

OVERVIEW

This page serves as collection of some quick examples designed to get one started. I will try to add more occasionally.

CODE EXAMPLES

Find events and write log messages

This sample is quite arbitrary. It will find all events, that are not in history, that have a severity of ERROR or CRITICAL and a firstTime of -2 days ago.

    use Zenoss:
    use DateTime;
    
    # Get the date two days ago
    my $start_time = sprintf("%s", DateTime->now->subtract(days => 2));
    
    # Create Zenoss API object
    my $api = Zenoss->connect(
        {
            username    => 'admin',
            password    => 'zenoss',
            url         => 'http://zenossinstance',
            timeout     => '300',
        }
    );
    
    # Find all events with a severity of ERROR and CRITICAL
    # that have a firstTime of -2 days ago
    my $result = $api->events_query(
        {
            params      => {
                severity    => [4,5],
                firstTime   => $start_time,
            },
        }
    );
    
    # Add a log message to each event found
    if ($result->is_success()) {
        my $decoded_result = $result->decoded();
        foreach my $event (@{$decoded_result->{'events'}}) {
            $api->events_write_log(
                {
                    evid        => $event->{'evid'},
                    message     => 'This is a test message!!',
                }
            );
        }
    } else {
        # something bad happened, lets print out to see what
        print $result->raw_response();
    }

Add a device

This sample adds a device and prints out the JobID

    use Zenoss;
    
    # Create Zenoss API object
    my $api = Zenoss->connect(
        {
            username    => 'admin',
            password    => 'zenoss',
            url         => 'http://zenossinstance',
            timeout     => '300',
        }
    );
    
    # Add a device
    my $result = $api->device_addDevice(
        {
            deviceName  => 'newdevice',
            deviceClass => '/Server/Linux',
            model       => JSON::true,
        }
    );
    
    # Print the JobID that this device will be processed under
    my $result_decoded = $result->decoded();
    if ($result->is_success()) {
        printf("Success = %s, JobID = %s", $result_decoded->{'success'}, $result_decoded->{'jobId'});
    } else {
        # do something if the http response was bad
    }

This example could be made more advanced to bind templates to a device very easily.

    use Zenoss;
    
    # Create Zenoss API object
    my $api = Zenoss->connect(
        {
            username    => 'admin',
            password    => 'zenoss',
            url         => 'http://zenossinstance',
            timeout     => '300',
        }
    );
    
    # Find devices in /Server/Linux
    my $devices_found = $api->device_getDevices(
        {
            params  => {
                deviceClass => '/Server/Linux',
            },
        }
    )->decoded();
    
    # Print the names of the devices found then their available templates
    foreach my $device (@{$devices_found->{'devices'}}) {
        print "[$device->{'name'}] has the following available templates:\n";
        my $available_tempaltes = $api->device_getTemplates(
            {
                id  => $device->{'uid'},
            }
        )->decoded();
        
        # Print the templates
        foreach my $templates (@{$available_tempaltes}) {
            print "\t$templates->{'text'}\n";
        }
        
    }
