Lync Server 2013 中的伺服器效能報告Server Performance Report in Lync Server 2013

 

主題上次修改日期: 2012-10-01Topic Last Modified: 2012-10-01

「伺服器性能報告」會提供 Microsoft Lync Server 2013 伺服器的清單,該清單已經歷最高百分比的低通話量。The Server Performance Report provides a list of Microsoft Lync Server 2013 servers that have experienced the highest-percentage of poor calls. 報告依伺服器類型分解伺服器,報告下列類型的個別統計資料:The report breaks down servers by server type, reporting separate statistics for the following types:

  • 中繼伺服器Mediation Server

  • A/V Conferencing ServerA/V Conferencing Server

  • A/V Edge ServerA/V Edge Server

  • 閘道 (轉送伺服器) Gateway (Mediation Server)

  • 閘道 (轉送伺服器旁路) Gateway (Mediation Server bypass)

  • 影片 (包含 A/V 會議伺服器及 A/V Edge server 的影片度量) Video (including video metrics for A/V Conferencing servers and A/V Edge servers)

  • 應用程式共用 (包括 A/V 會議伺服器和 A/V Edge server 的應用程式共用計量,) Application Sharing (including application sharing metrics for A/V Conferencing servers and A/V Edge servers)

請務必注意,此報告中顯示的排名為相對排名。It’s important to note that the ranking shown in this report as relative rankings. 例如,假設您的最壞執行伺服器在其1000的來電中有一個不佳的呼叫。For example, suppose your worst-performing server had one poor call among its 1,000 placed calls. 這是1% 的可接受百分比。That's a more-than-acceptable percentage of .1%. 不過,如果這是執行最壞的伺服器,也就是 (也就是說,如果其他所有伺服器的呼叫百分比不佳,甚至低於 0.1% ) ,則該伺服器仍會出現在伺服器效能報告上。However, if that's the worst-performing server you have (that is, if all your other servers have a poor call percentage even lower than .1%), then that server will still appear on the Server Performance Report.

伺服器效能報告的最佳用法Making the Best Use of the Server Performance Report

伺服器效能報告提供了多種篩選資料的方式;例如,您可以篩選網路類型 (來自有線連線的呼叫,以及從防火牆內部撥打的撥號類型) 和 access 類型 (呼叫從防火牆內部所撥打的呼叫,而不是來自防火牆) 以外的呼叫。The Server Performance Report provides a number of ways to filter data; for example, you can filter on network type (calls made from a wired connection vs. calls made from a wireless connection) and access type (calls made from inside the firewall vs. calls made from outside the firewall). 在查看伺服器效能報告以利用這些篩選器時,是一個不錯的主意。It's a good idea when viewing the server performance report to make use of these filters. 例如,假設您的轉送伺服器的呼叫百分比不佳,3.24%。For example, suppose you have a Mediation Server that has a poor call percentage of 3.24%. 如果您只是在無線通話時查看,則相同的伺服器可能會有接近20% 的低通話百分比。If you look solely at wireless calls, that same server might have a poor call percentage approaching 20%. 這表示伺服器在無線通話時發生困難,因為伺服器沒有有線通話的問題,所以發生部分掩蓋問題。That means that the server was having difficulty with wireless calls, a problem that is partially obscured because the server was not having problems with wired calls.

篩選Filters

篩選器可以讓您傳回更精確的資料集或者以不同方法檢視傳回的資料。Filters provide a way for you to return a more finely-targeted set of data or to view the returned data in different ways. 例如,伺服器效能報告可讓您執行下列作業:依伺服器類型篩選傳回的資料,或透過網路類型 ((即有線或無線) )。For example, the Server Performance Report enables you to do such things as filter the returned data by server type or by network type (that is, wired or wireless). 您也可以選擇資料的分組方式。You can also choose how data should be grouped. 在此情況下,資料會依小時、日、周或月進行分組。In this case, data is grouped by hour, day, week, or month.

姓名Name 可以排序Can Sort On 描述Description

伺服器Server

No

伺服器的名稱/IP 位址。Name/IP address of the server.

通話數量Call volume

No

撥打的通話總數。Total number of calls made.

通話百分比不佳Poor call percentage

No

分類為不良的呼叫總數。Total number of calls classified as poor. 不佳的來電是指至少有一個衡量的衡量值超出允許的值 (例如,來電已有過高的抖動) 。A poor call is any call which at least one of the measured metrics exceeded the allowed value (for example, a call that experienced excessive jitter).

來回行程 (毫秒) Round trip (ms)

Yes

即時傳輸通訊協定 (RTP) 封包移至另一個端點後再進行的平均 (量(毫秒)) 所需)。Average amount of (in milliseconds) required for a real-time transport protocol (RTP) packet to travel to another endpoint and then back. 在100毫秒或更少的來回行程時間,會考慮可接受的品質。Round-trip times of 100 milliseconds or less are considered of acceptable quality.

高來回行程值可能是由國際通話路由所造成;路由傳送錯誤;或重載的媒體伺服器。High round-trip values can be caused by international call routing; a routing misconfiguration; or an overloaded media server. 較高的往返時間會導致使用雙向即時音訊交談的困難。High round-trip times result in difficulties with two-way, real-time audio conversations.

MOS) 降級 (Degradation (MOS)

Yes

通話期間 (MOS) 效能的平均平均觀點量。Average amount of mean opinion score (MOS) degradation experienced during a call. 降級值的範圍從低0.0 到高5.0。Degradation values can range from a low of 0.0 to a high of 5.0. 值0.5 或更少代表可接受的降級。A value of 0.5 or less represents acceptable degradation. 在過去,平均選項分數的計算方式是讓使用者以1到5的比例來評分通話的品質。Historically, mean options scores were calculated by having users rate the quality of a call on a scale of 1-to-5. 在 Lync Server 中,監控伺服器會使用一組演算法來預測使用者對通話的評分方式。In Lync Server, the Monitoring Server uses a set of algorithms to predict how users would have rated a call.

高降級值可能是由於擁塞、缺乏頻寬、無線擁塞或干擾或超載媒體伺服器或端點所造成。High degradation values can be caused by congestion, lack of bandwidth, wireless congestion or interference, or an overloaded media server or endpoint. 高降級導致音訊失真或遺失。High degradation results in distorted or lost audio.

High loss rates are generally caused by congestion, lack of bandwidth, wireless congestion or interference, or an overloaded media server. 封包遺失通常會導致音訊失真或遺失。Packet loss typically results in distorted or lost audio.

抖動 (毫秒) Jitter (ms)

Yes

在 RTP 封包抵達之間偵測到的平均抖動。Average jitter detected between RTP packet arrivals. (抖動是指 " 通話的 shakiness 量 " 。 ) 高抖動值通常是由擁塞或超載的媒體伺服器所造成,而且會產生失真或遺失的音訊。(Jitter is a measure of the "shakiness" of a call.) High jitter values are typically caused by congestion or an overloaded media server, and result in distorted or lost audio.

(隱藏的音訊範例是一種技術,它通常是因丟棄網路資料包而造成的強烈轉換。 ) 高值表示因封包遺失或抖動所造成的 concealment 損毀,並產生失真或遺失的音訊。(A concealed audio sample is a technique used to smooth out the abrupt transition that would usually be caused by dropped network packets.) High values indicate significant levels of loss concealment applied caused by packet loss or jitter, and results in distorted or lost audio.

修復延伸比率Healer stretched ratio

Yes

延伸音訊樣本的平均比例與樣本總數總數。Average ratio of stretched audio samples to the total to the total number of samples. (延伸的音訊是已展開的音訊,可在偵測到網路封包時,維持通話品質。 ) 高值會指出抖動所造成的大量樣本拉伸層級,並導致音訊的自動或失真。(Stretched audio is audio that has been expanded to help maintain call quality when a dropped network packet has been detected.) High values indicate significant levels of sample stretching caused by jitter, and result in audio sounding robotic or distorted.

修復壓縮比例Healer compressed ratio

Yes

壓縮音訊樣本的平均比率與樣本總數。Average ratio of compressed audio samples to the total number of samples. (壓縮音訊是一種已壓縮的音訊,可在偵測到網路資料包時,維持通話品質。 ) 高值表示減少抖動所造成的範例壓縮層級,並導致音訊的快向或失真。(Compressed audio is audio that has been compressed to help maintain call quality when a dropped network packet has been detected.) High values indicate significant levels of sample compression caused by jitter, and result in audio sounding accelerated or distorted.
