How to fetch an ESXi host maintenance mode history via any vSphere SDK?

[Subeesh KK]

Hello All,

I have a requirement to fetch the history details of an esx host maintenance mode details - like how many times the host went on maintenance mode, etc - via vSphere SDK or any other API . Is it possible? 

I tried using vmwarephp library as follows :

                $vhostcon = new \Vmwarephp\Vhost($this->provider->ip . ':443', $this->provider->user, $this->provider->pwd);

                $vhost = $vhostcon->getService();

 

                // 1. Get EventManager ManagedObject Reference

                $eventManagerRef = $vhost->getServiceContent()->eventManager;

 

                // 2. Define the time range

                $beginTime = new \DateTime('-30 days');  // Or your custom start time

                $endTime = new \DateTime();              // Up to now

 

                // 3. Find all hosts

                $hosts = $vhost->findAllManagedObjects('HostSystem', array('name',));

 

                 // 4. Loop over each host and fetch maintenance events

                foreach ($hosts as $host) {

                    $hostName = $host->name;

 

                    // Build EventFilterSpec

                    $eventFilterSpec = new stdClass();

 

                    // Time filter

                    $eventFilterSpec->time = new stdClass();

                    $eventFilterSpec->time->beginTime = $beginTime->format(DATE_ATOM); // ISO 8601

                    $eventFilterSpec->time->endTime = $endTime->format(DATE_ATOM);

 

                    // Entity filter (the host)

                    $eventFilterSpec->entity = new stdClass();

                    $eventFilterSpec->entity->entity = $host->toReference(); // Returns ManagedObjectReference

                    $eventFilterSpec->entity->recursion = 'self'; // Only events directly related to the host

 

                    // Event types filter

                    $eventFilterSpec->eventTypeId = [

                        'EnteredMaintenanceModeEvent',

                        'ExitedMaintenanceModeEvent',

                    ];

 

                    // Wrapper for EventFilterSpec

                    $filterWrapper = new stdClass();

                    $filterWrapper->_this = $eventManagerRef->toReference();     // IMPORTANT!

                    $filterWrapper->filter = $eventFilterSpec;

                    $filterWrapper->maxCount = 100; // Or null to get all

                    $filterWrapper->delayed = false;

                   // Query events - NOT WORKING .. ???

                    $events = $vhost->getServiceContent()->eventManager->QueryEvents($eventManagerRef,$filterWrapper);

 

                    // Display results

                    if (!empty($events)) {

                        echo "=== Events for host: $hostName ===\n";

                        foreach ($events as $event) {

                            echo "[" . $event->createdTime . "] " . $event->_ . "\n"; // fullFormattedMessage

                        }

                        echo "\n";

                    }

                }

The problem is with calling QueryEvents . Can someone help me here please as I am not very experienced in this side. 

Thank you,
