Monitor server statistics using ArcGIS Server Manager
使用ArcGIS Server Manager監控Server統計信息
ArcGIS Server records various service statistics, such as total requests, average response time, and timeouts, and reports this information in ArcGIS Server Manager as one or a series of graphs. Administrators and publishers can use this information to monitor service activity and better understand how clients are using services.?
ArcGIS Server記錄了種類繁多的服務統計信息。比方總請求數，平均響應時間。超時等。ArcGIS Server管理器會將這些信息以圖形曲線的方式報告給用戶，ArcGIS Server管理員和服務公布人員可以依據這些信息來監控服務活動，更好的了解客戶端是怎么使用這些服務的。?
ArcGIS GeoEvent Processor stream services
The ArcGIS GeoEvent Processor for Server extension exposes a new type of service, called the stream service, which emphasizes low latency, real-time data dissemination, for client/server data flows. Clients connecting to a stream service begin receiving data immediately upon subscribing to the service. Clients can specify and reconfigure both spatial and attribute constraints without first unsubscribing and then reconnecting to the service.
在ArcGIS GeoEvent處理器的服務器擴展暴露了一個新的服務類型。稱為流服務，它針對客戶端/服務器的數據流，強調低延遲，實時數據公布。客戶端連接到一個流服務后。立即為訂閱的服務接收數據。客戶端可以在不退訂服務的情況下，指定并又一次配置空間和屬性限制，然后又一次連接到該服務。
What is a Stream Service?
A Stream Service is a new type of ArcGIS Server service which emphasizes low latency, real-time data dissemination, for client/server data flows. Clients connecting to a Stream Service begin receiving data immediately upon subscribing to the service. Clients can specify and reconfigure both spatial and attribute constraints without first unsubscribing and then reconnecting to the service.
The?ArcGIS GeoEvent Processor for Server?extension must be incorporated into your GIS Enterprise in order to leverage Stream Services. Initially, only clients developed using the ArcGIS API for JavaScript will be able to connect to a Stream Service. Future releases will support a wider variety of client subscriptions.
See?What is GeoEvent Processor?for more information on?ArcGIS GeoEvent Processor for Server.
Stream Services leverage WebSocket technology which supports full-duplex, bi-directional communication. This enables clients to specify the data they want to receive without having to unsubscribe and reestablish their connection to the service. Clients are able to filter Stream Service data by specifying either spatial or attribute constraints.
Connecting to a Stream Service to receive a real-time data feed allows you to separate the basic need of immediate event visualization from the need to persist data in a database. By configuring a?GeoEvent Processor?output to broadcast event data via a Stream Service you will have the option of archiving or persisting event data in an enterprise data store, but doing so is not a requirement for data visualization.
The illustration below compares how feature data has traditionally been received, processed, and consumed with how real-time data is received and broadcast using Stream Services.

OGC WFS 2.0 support
The Open Geospatial Consortium (OGC) Web Feature Services (WFS) you create and host on ArcGIS Server now support the WFS 2.0 specification. The ArcGIS Server implementation of the WFS 2.0 specification addresses the required features of the simple WFS profile, transactions, response paging, and stored queries.
ArcGIS10.3 for ?Server上如今支持WFS2.0規范。
在WFS2.0規范的ArcGIS Server實現攻克了簡單的WFS配置文件，交互，尋呼響應。和存儲查詢所需的功能。

既然有了ArcGIS10.3新版本號的推出，那么版本號間的兼容性問題肯定是大家所關注的。以下來看一下關于這個問題的解答。以下我就不再進行翻譯了！
Can I view and use my?10.3?services within an earlier version of ArcGIS for Desktop?
Yes. You can add?10.3?services to earlier versions of ArcGIS for Desktop and use them in the same way that you used them in the past, including as a layer in ArcMap. This is accomplished purely through web service communication and not the local (DCOM) connections that are an option in 10.0. The fundamental structure and format of REST and SOAP requests a client makes to an ArcGIS Server web service have not changed at version10.3.
If your?10.3?ArcGIS Server site is federated with?Portal for ArcGIS?and you are connecting from a pre-10.2 version of ArcGIS for Desktop, you must access your services through ArcMap using?Add Data?>?Add Data from Portal for ArcGIS. You cannot connect to the server by clicking?Add ArcGIS Server.
Can I publish a service to?10.3?using an earlier version of ArcGIS for Desktop?
Generally, you can use a 10.1 or later version of ArcGIS for Desktop to publish a service to a?10.3?server. However, there are some restrictions to publishing with 10.1 if you are attempting to take advantage of functionality exclusive to?10.3:
- If you're using web-tier authentication for your administrative connection, you must use 10.2 or later to publish.
- If you are publishing to a server that is federated with Portal for ArcGIS, you must use 10.2 or later to publish.
Can I publish a service to a 10.1 or 10.1 SP1 server using ArcGIS?10.3?for Desktop?
Yes. You can publish services to a 10.1 or 10.1 SP1 version of ArcGIS Server using a?10.3?version of ArcGIS for Desktop. However, you will not be able to take advantage of any new?10.3?functionality until your server is upgraded to?10.3.
Can I administer a?10.3?server using an earlier version of ArcGIS for Desktop?
No. You must use version?10.3?to administer a?10.3?server. In the scenario where you have upgraded to ArcGIS?10.3for Server but you have not upgraded Desktop, consider using the ArcGIS Server Manager web application to administer your server.
Can I administer a 10.0 server using a later version of ArcGIS for Desktop?
No. You must use version 10.0 to administer a 10.0 server. In the scenario where you have upgraded to ArcGIS?10.3for Desktop and you need to administer a server from an earlier version, consider using the ArcGIS Server Manager web application to administer the server.
Can I configure an earlier version of the ArcGIS Web Adaptor with my?10.3?server?
No. To configure the Web Adaptor with ArcGIS Server, both products need to be running version?10.3.
Can I install the ArcGIS?10.3?Web Adaptor (IIS) on the same machine as a previous version of the?ArcGIS Web Adaptor (IIS)?
Yes. Beginning at 10.2.1, you can have a 10.2.1 version of the?ArcGIS Web Adaptor (IIS)?installed alongside one other previous version of the Web Adaptor on the same machine. For example, you can have a 10.1 SP1 version and a?10.3?version of the Web Adaptor installed on the same web server.
As with previous releases, the Web Adaptor's version must always match the version of ArcGIS Server. For example, you cannot configure a?10.3?version of the Web Adaptor with ArcGIS 10.2 for Server.
If you want to upgrade a previous version of the?ArcGIS Web Adaptor (IIS)?to?10.3, you'll need to uninstall the old version and install the?10.3?setup. After installing?10.3, you'll need to configure the Web Adaptor with ArcGIS Server.

In?10.3, can I reuse a map cache I created in an earlier version so I don't have to re-create the cache?
Yes. Map caches from 10.1 are available immediately. With 10.0 caches, make sure your cache is sitting in a server cache directory registered with ArcGIS?10.3?for Server (either by moving your cache or by registering its current location as a server cache directory). Then republish the service at?10.3?with the same name it used in 10.0 and configure the service to point to the appropriate cache directory.?
Using?10.3, can I connect to earlier versions of the geodatabase?
Yes. See?Client and geodatabase compatibility?for a list of compatible versions.
Can I publish services to ArcGIS?10.3?for Server that contain data from a previous geodatabase version?
In most cases, the geodatabase version does not have to match the version of ArcGIS Server. For specific information on which geodatabase versions are supported with ArcGIS?10.3?for Server, see?Client and geodatabase compatibility.
Do I need to upgrade my geodatabase in order to use it as ArcGIS?10.3?for Server's Managed Database?
A geodatabase version of 9.3 or later can be used as ArcGIS?10.3?for Server's Managed Database. To learn more about ArcGIS Server's Managed Database, see?Copying data to the server automatically when publishing.
