ATG search installation and search engine log files

Here I would like to explain how your ATG search folder structure looks like after you do the ATG search installation and also about the search engine log files.

To get the ATG search, you need to install the ATGSearch<version>Windows.exe after you do the ATG installation. When you install ATG search, the generated folders include an OS dependant folder. In the below screen shot, you could see the "i686-win32-vc71" folder and this is generated since the ATG search ins installed in a windows machine.


The ATG search engine is actually an exe file inside this "i686-win32-vc71" folder. Below screen shot give you an idea about the "atgsearch.exe", which is the search engine application. This search engine application (atgsearch.exe) is started by a remote launcher call from the BCC search administration UI. 



The log files like "atgsearch_20120106112413_568.log" are the search engine log files where you could see the engine logs like the index file used by the search engine,enigne load ,enigne throughput and query response time,.. You could enable the debug logging for the search engine to find the different request processing by the engine including the ip address of the requesting host. Also the search engine start and end time can be obtained from this log.



The engine log will show slow request based on the <SlowRequestThreshold> parameter in the AEConfig.xml, like <SlowRequestThreshold>5000</SlowRequestThreshold>. If you set engineLogLevel to D in launchingService component, you will be able to see the ip address of  of the requesting host.

                 engineLogLevel = D

Example of the search engine log with requesting host ip:
2011/03/22 11:12:59 : DEBUG : Server : 0 : Accept socket 12068 at port 4790 from IP 100.222.46.124
2011/03/22 11:12:59 : DEBUG : Server : 0 : AEXmlWorker::Shutdown
2011/03/22 11:12:59 : INFO : Server : 0 : Shutdown received
2011/03/22 11:12:59 : DEBUG : Server : 0 : Accept socket 12068 at port 4791 from IP 100.222.46.124
2011/03/22 11:12:59 : INFO : Server : 0 : Waiting for pending requests to complete.
2011/03/22 11:12:59 : INFO : Server : 0 : Exiting engine
2011/03/22 11:12:59 : INFO : Server : 0 : Scheduled shutdown.


Consider the following search engine log :

2011/03/11 09:36:35 : INFO : Server : 0 : load: 0.6875 throughput: 1.72804 q/s time: 6.60434 s

Load  of .6 means that 60% of the search engine thread are active. Throughput is the number of requests that the engine is able to server per second. Time is the average response time.

So load is specified as percentage and 0.6875 is roughly 69 percent of load, where as anything greater then 1 would suggest the search engine is overburden. Throughput is telling us how many requests the engines can handle across all the cores of the engine hosted box. So throughput is kind of like saying how many request can be placed into the bucket. But it doesn't say how fast the objects in the bucket are moving.

    Hi,

    I have a problem with Service Center's search engines, ATGOrder and ATGProfile. Both has a scheduled shutdown at midday and midnight causing searches and live indexing to stop. How can I turn the scheduled shutdown off?

    Thanks in advance and good blog!

Basic design decisions for a commerce search setup ( with an ATG Search view)

In this blog I would like to explain the basic set of configuration/design decisions needed to setup an ATG search project. Most of these design decisions are common for all Enterprise search applications. 1. Decide the searchable properties :   This means the properties that the business want the user to search in the ecommerce platform. In ATG search these are configured as the text properties in the product-catalog-output-config.xml ( the definitionFile of the \atg\commerce\search\ProductCatalogOutputConfig). Usually the displayName of product/sku, displayName of department/category/sub-category, skuId, brandName are the properties configured as searchable. 2. Decide the search refinement properties or the faceted properties :   After a user search for a keyword, search refinement is the next step done to filter his results. ATG supports the search refinement using the Faceted Search concept. Read more about facted search @...

ATG Search Indexing - overview of different steps in search indexing

Read more about the search indexing behind the scene steps @  http://tips4ufromsony.blogspot.in/2011/12/atg-search-indexing-behind-scene-steps.html ATG Search prepares searchable content by indexing the products specified in the XML definition file (/atg/commerce/search/ProductCatalogOutputConfig). Generally there are two types of indexing 1.  Full Indexing  --> all data taken for indexing 2.  Incremental Indexing --> only changed data will be taken for indexing When full indexing is triggered, following happens:    1. The out of box component BulkLoader will call IndexedItemsGroup.getGroupMembers() to load the products to the XHTL document. It prevents uncategorized products from getting indexed. The definition file format begins with a top-level item as a product and includes the properties of parent category and childskus. For each product, the set of Variant Producers configured in ProductCatalogOutputConfig is execute...

ATG Search - high level overview of product-catalog-output-config.xml and XHTMLs

The definition file format begins with a top-level item element that specifies the repository and item descriptor to use, and then lists the properties of that item type to include. The top-level item element has the is-document attribute set to true. This attribute specifies that an XHTML document should be generated for each item of that type (in this case, each user item). Property values that come from standard JavaBean properties of the RepositoryItem object (rather than dynamic bean properties) are specified using a dollar-sign ($) prefix. The item element has an is-multi attribute for specifying multi-value properties. If a property is an Array, Collection or Map  you should set this attribute to true. Eeach ATG Search document is uniquely identified by a URL (typically the path name of the file on the file system). In the XHTML documents that the ATG platform generates from repository items, meta properties are represented by meta tags in the head of the document, whi...
