Question

我正在使用此库的修改版本（https://github.com/kamermans/HAProxyAPI）来连接到我的所有loadbalancer实例。但是，要知道连接的服务器是活动实例还是备份实例，我需要从统计信息中添加“bck”属性。（我无法使用以下方法访问它：$ loadbalancer ['haproxy_stats'] - ＆gt; info-＆gt; line-＆gt; data-＆gt; bck）

请注意，此属性：$ loadbalancer ['haproxy_stats'] - ＆gt; health-＆gt; backup。不是我需要的，这只表示备份服务器是否存在于此负载均衡器中。

如何访问此属性？

示例Haproxy Stats来自：HAProxy_Stats :: get（$ exec） - ＆gt; getServiceStats（$ interface，$ server）;

结果（print_r）如下所示：

HAProxy_Stats_Service对象（ [info] =＆gt; HAProxy_Stats_Info对象（ [map：protected] =＆gt;排列（ [pxname] =＆gt; proxy_name [svname] =＆gt;服务名称 [重量] =＆gt;重量 [pid] =＆gt; PROCESS_ID [iid] =＆gt; proxy_id [sid] =＆gt; service_id为 [tracked] =＆gt;追踪 [type] =＆gt;类型）

如果是issue was created for it，这个问题会得到更快的回答，但是我觉得迟到的时间要晚得多：）

这确实是正确的财产：

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

但是，如果您正在检查负载均衡器BACKEND的统计信息，它将只返回备份节点的数量。如果您想知道单个节点是活动的还是备份的，您需要像这样迭代它们：

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";
    }
}

这将产生如下输出：

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
