Arka fon:
Tutarsız halka arabellek ayarlarına sahip yüksek hacimli bir önbellekleme ad sunucusu ortamını (Redhat Enterprise Linux 5.8, IBM System x3550) miras ettim: eth0 için 1020 ve eth1 için 255. eth0, yerel veri merkezinin anahtar 1'ine, eth1 aynı anahtarın 2'sine bağlanır. Kümedeki her sunucu, eth0 veya eth1'in etkin arabirim olup olmadığı arasında değişir ve her küme farklı bir bölgede bulunur. Halka tamponlarının açıkça tutarlı hale getirilmesi gerekir.
İşler daha da zorlaşıyor: ISC bilgi tabanının giden tıkanıklık ile ilgili olduğunu iddia eden bir dizi ad sunucusunun neden "yanıt gönderme hatası: ayarlanmadı" hatalarını sık sık günlüğe kaydettiğini araştırırken yukarıdaki sorunu keşfettim . Daha yüksek halka arabelleği ayarına (1020) sahip sunucular ifconfig'e daha az paket bırakır (beklendiği gibi), ancak en yüksek yük gruplarından birinde günde yaklaşık 20k kez büyük bir sıklık ile yukarıdaki hatayı kaydetme eğilimindedir. Buna `` Grup 1 '' diyeceğiz. Alt halka tamponu (255) ayarına sahip sunucular günde önemli ölçüde daha fazla gelen paket bırakır (yine beklenir), ancak BIND hatasının çok daha az örneğine sahiptir, genellikle aynı yük grubunda 0-150.
Burada da büyük bir gizem yok. DNS'yi önbelleğe alma özyinelemeli bir hizmettir: bir şey önbelleğe alınmazsa, sunucunun bu soruyu sonunda bir yanıt döndürene kadar birden çok sorgu yapması gerekir. Bu bir (bir giriş) -> (çok sayıda) sorgu ilişkisidir. RX halka arabelleklerini düzeltmek, bu sayının karttaki yeni bir değere eşitlenmesine neden olmalıdır ve oradan çekirdeğin giden ağ kuyruğunu proc (wmem_max / wmem_default) olarak ayarlamak iyi bir fikir olacaktır.
Yapılandırma değişikliklerinin bir performans sorunu üzerindeki etkisini ölçmeyi seviyorum, bu nedenle üretim değişiklikleri yapmaya başlamadan önce bazı verileri toplamak için bir rapor yazdım. Grup 1'deki ilk iki sunucu için çıktıya bir örnek:
group1-01
RX: 7166.27/sec av.
TX: 7432.57/sec av.
RXDROP: 7.43/sec av.
unset_err: 27633
group1-02
RX: 7137.37/sec av.
TX: 7398.50/sec av.
RXDROP: 9.94/sec av.
unset_err: 107
Bunlar formüller. Bunun yerel bir komut dosyası olduğunu ve sunucu başına korunması gereken kabuk komut dosyalarına güvenilmediğini unutmayın.
RXPACK=$(ssh $server "sar -n DEV -f /var/log/sa/sa$(date --date=yesterday '+%d') | grep \"Average: .*\$(awk '{if (\$2 == "00000000") { print \$1 }}' /proc/net/route)\" | awk '{print \$3}'" 2>/dev/null)
TXPACK=$(ssh $server "sar -n DEV -f /var/log/sa/sa$(date --date=yesterday '+%d') | grep \"Average: .*\$(awk '{if (\$2 == "00000000") { print \$1 }}' /proc/net/route)\" | awk '{print \$4}'" 2>/dev/null)
RXDROP=$(ssh $server "sar -n EDEV -f /var/log/sa/sa$(date --date=yesterday '+%d') | grep \"Average: .*\$(awk '{if (\$2 == "00000000") { print \$1 }}' /proc/net/route)\" | awk '{print \$6}'" 2>/dev/null)
TXDROP=$(ssh $server "sudo grep 'error sending response: unset' /var/log/dns_named.1" 2>/dev/null | wc -l)
Bu raporu tüm önbellekleme DNS ortamlarımda çalıştırmaya başladığımda, Grup 2'yi arayacağımız neredeyse aynı paket yüküne sahip başka bir grubun hiç sorun yaşamadığını fark ettim :
group2-01
RX: 7066.44/sec av.
TX: 7345.95/sec av.
RXDROP: 0.00/sec av.
unset_err: 0
group2-02
RX: 7019.18/sec av.
TX: 7312.47/sec av.
RXDROP: 0.00/sec av.
unset_err: 0
Soru:
Grup2 neden RX halka arabelleklerinin net.core.wmem_default
/ / veya daha fazla ayarlanmasına gerek kalmadan bu şekilde davranıyor net.core.wmem_max
? Ne olursa olsun, halka tamponlarını normalleştirmem gerekecek, ancak / proc içindeki wmem değerleri ile oynamaya başlamadan önce burada başka neler olduğunu anlamak istiyorum.
Aklıma gelen tek şey, uygulamanın uygulama tarafından daha hızlı boşaltılmasıdır, ancak ağ yığını ayarlaması, çok fazla uygulamalı deneyime sahip olduğum bir şey değildir ve ikinci görüş almak istiyorum. (bazı ettool sayaç isimlerinde gözlerim parlıyor, inkar etmeyeceğim)
Aşağıdakileri olasılık olarak ortadan kaldırdım. Kanıtlar bölücüden sonra gelir.
- Halka tampon düzeni aynıdır. (grup1 ve grup2'nin ilk sunucusu aynı yapılandırıldı, grup1 ve grup2'nin ikinci sunucusu aynı yapılandırıldı)
- Varsayılan ağ geçidi düzeni aynıdır.
- Ağ kartları aynı. (Broadcom BCM5708)
- Ethtool tarafından bildirilen ürün yazılımı sürümü aynıdır. (BC 4.0.3 ipms 1.6.0)
sysctl -a
çıktı her iki grubun ilk sunucuları ile her iki grubun ikinci sunucuları arasında eşleşir. (çekirdek ve fs bölümleri hariç)- Grup 1 ve Grup 2'deki toplam sunucu sayısı aynıdır. (10)
Gizlilik nedeniyle, bilgileri hariç tutmak için kullandığım raw named.conf dosyasını veya grep filtresini gösteremiyorum. Aşağıdaki konfigürasyon parametrelerinin dört sunucu arasında sabit kalması için benim sözüme gerek var:
notify no;
allow-transfer { none; };
allow-recursion { any; };
allow-query { any; };
allow-query-cache { any; };
recursive-clients 100000;
max-cache-size 2G;
max-ncache-ttl 900;
Aşağıda çok miktarda sistem bilgisi bulunmaktadır. "Hosthash" sadece döngünün her yinelemesinin aslında gerçek ana bilgisayar adını göstermeden farklı bir sunucuya vurduğunu göstermektir.
Ana bilgisayar karmaları:
group1-1: dc78abcb154b74c87feecb3f35222263d40c028c
group1-2: 9fe491d58fd1e7d4e21e5bf10c164e4cf66e884b
