Info

The Thread Dump screen lets you inspect the currently active threads on your server. Each thread is listed and access to the stacktraces is available where applicable. Icons to the left indicate the state of the thread: for example, threads with a green check-mark in a green circle are in a "RUNNABLE" state. On the right of the thread name, a down-arrow means you can expand to see the stacktrace for that thread. When you move your cursor over a thread name, a box floats over the name with the state for that thread. Thread states can be: State NEW RUNNABLE BLOCKED WAITING TIMED_WAITING TERMINATED Meaning A thread that has not yet started. A thread executing in the Java virtual machine. A thread that is blocked waiting for a monitor lock. A thread that is waiting indefinitely for another thread to perform a particular action. A thread that is waiting for another thread to perform an action for up to a specified waiting time. A thread that has exited. When you click on one of the threads that can be expanded, you'll see the stacktrace, as in the example below: Apache Solr Reference Guide 4.6 18
Inspecting a thread You can also check the Show all Stacktraces button to automatically enable expansion for all threads. Core-Specific Tools In the left-hand navigation bar, you will see a pull-down menu titled "Core Selector". Clicking on the menu will show a list of Solr cores, with a search box that can be used to find a specific core (handy if you have a lot of cores). When you select a core, such as collection1 in the example, a secondary menu opens under the core name with the administration options available for that particular core. After selecting the core, the central part of the screen shows Statistics and other information about the core you chose. You can define a file called Extra" part of this main screen. admin-extra.html that includes links or other information you would like to display in the "Admin On the left side, under the core name, are links to other screens that display information or provide options for the specific core chosen. The core-specific options are listed below, with a link to the section of this Guide to find out more: Analysis - lets you analyze the data found in specific fields. Config - shows the current configuration of the <strong>solr</strong>config.xml file for the core. Dataimport - shows you information about the current status of the Data Import Handler. Documents - provides a simple form allowing you to execute various Solr indexing commands directly from the browser. Ping - lets you ping a named core and determine whether the core is active. Plugins/Stats - shows statistics for plugins and other installed components. Query - lets you submit a structured query about various elements of a core. Replication - shows you the current replication status for the core, and lets you enable/disable replication. Schema - describes the schema.xml file for the core. Schema Browser - displays schema data in a browser window. Analysis Screen The Analysis screen lets you inspect how data will be handled according to the field, field type and dynamic rule configurations found in schema.xml. You can analyze how content would be handled during indexing or during query processing and view the results separately or at the same time. Ideally, you would want content to be handled consistently, and this screen allows you to validate the settings in the field type or field analysis chains. Enter content in one or both boxes at the top of the screen, and then choose the field or field type definitions to use for analysis. The standard output (shown if "Verbose Output" is not checked) will display the step of the analysis and the output based on the current settings. If you click the Verbose Output check box, you see Apache Solr Reference Guide 4.6 19
