訪問PHP保護的對象屬性（haproxy）

我正在使用此庫的修改版本（https://github.com/kamermans/HAProxyAPI）連接到我的所有負載均衡器實例。但是，要知道所連接的服務器是活動實例還是備份實例，我需要從統計信息中尋找'bck'屬性。（我無法使用：$ loadbalancer ['haproxy_stats'] - > info-> line-> data-> bck）訪問PHP保護的對象屬性（haproxy）

請注意，此屬性爲：$ loadbalancer ['haproxy_stats'] - > health-> backup。不是我需要的那個，這隻表示備份服務器是否存在於此負載均衡器中。

如何訪問此屬性？示例Haproxy Stats來自：HAProxy_Stats :: get（$ exec） - > getServiceStats（$ interface，$ server）;示例代碼如下：HAProxy_Stats :: get（$ exec） - > getServiceStats（$ interface，$ server）;

結果（的print_r）看起來像這樣：

HAProxy_Stats_Service對象（ [信息] = > HAProxy_Stats_Info對象（ [圖：保護] = >陣列（ [pxname] = > proxy_name [svname] = > service_name [weight] = > weight [pid] = > process_id [iid] = > proxy_id [SID] = >的service_id [跟蹤] = >跟蹤 [型] = >類型）

這將已經得到了更快的回答，如果一個issue was created for it，但比我從來沒有想過更好的遲到:)

這確實是正確的屬性：

$loadbalancer['haproxy_stats']->health->backup

但是，如果您正在檢查負載均衡器BACKEND的統計信息，它只會返回備份節點的數量。如果你想知道，如果個別節點是主動或備份，您將需要遍歷他們是這樣的：

foreach ($stats->getBackendNames() as $backend) { 
    foreach ($stats->getServerNames($backend) as $server) { 
     $service = $stats->getServiceStats($backend, $server); 
     echo "$backend:$server\n"; 
     echo " Active: {$service->health->active}\n"; 
     echo " Backup: {$service->health->backup}\n"; 
     echo " Health: {$service->health->status}\n\n"; 
    } 
}

這將產生這樣的輸出：

foo-cloud:FRONTEND 
    Active: 
    Backup: 
    Health: OPEN 

production-nodes:hiphop-node01-us.foocloud.com 
    Active: 1 
    Backup: 0 
    Health: UP 

production-nodes:apache-node01-us.foocloud.com 
    Active: 0 
    Backup: 1 
    Health: UP 

production-nodes:hiphop-node02-us.foocloud.com 
    Active: 1 
    Backup: 0 
    Health: UP 

production-nodes:apache-node02-us.foocloud.com 
    Active: 0 
    Backup: 1 
    Health: MAINT 

production-nodes:BACKEND 
    Active: 2 
    Backup: 2 
    Health: UP 

stats:FRONTEND 
    Active: 
    Backup: 
    Health: OPEN 

stats:BACKEND 
    Active: 0 
    Backup: 0 
    Health: UP
