HAProxy サーバーの統計情報がコマンドで参照できるように設定します。 |
|
[1] | 必要なパッケージをインストールしておきます。 |
[root@dlp ~]# dnf -y install socat
|
[2] | HAProxy の設定です。 |
[root@dlp ~]#
vi /etc/haproxy/haproxy.cfg # 設定確認 # [global] セクション内に以下の設定があれば OK global ..... ..... stats socket /var/lib/haproxy/stats[root@dlp ~]# systemctl reload haproxy |
[3] | 以上の設定の後、以下のようにして参照可能です。 |
# 現在の状態を表示 [root@dlp ~]# echo "show info" | socat /var/lib/haproxy/stats stdio Name: HAProxy Version: 3.0.5-8e879a5 Release_date: 2024/09/19 Nbthread: 2 Nbproc: 1 Process_num: 1 Pid: 1350 Uptime: 0d 0h03m41s Uptime_sec: 221 Memmax_MB: 0 ..... .....
