The System Status page summarizes the state of all nodes, connectors, events and indexes across a cluster of AIE servers. It provides early warning when some part of the system shows unusual behavior.

Monitoring System Status

To monitor AIE system status, select Diagnostics -> System Status in the AIE Administrator, or by clicking System Health at the top of any Administrator page. The System Status screen appears showing data for:

  • Node health
  • Connector status
  • System events
  • AIE Index status
  • Performance monitoring graph

Note that you can:

  • Sort/resort any table by the desired data by clicking the desired column heading.
  • Hide the navigation pane with the show/hide button to see more or less of the status tables as desired.

System Status Information

Node Health

The Node Health table shows runtime statistics for each node in the AIE project. Look here to verify that nodes are running, and are not limited by available memory.

The table sorts the rows by Up Time, unless a node has gone off line. In that case the offline node moves to the top.




These are the nodes as defined in the project's topology-nodes.xml file.

Up Time

How long the node has been up and running.

CPU (%)

Current CPU load on the node.

Memory (%)

Current memory usage on the node.

GC (%)

Current garbage collection activity on the node.

Connector Status

The Connector Status table shows a condensed version of current connector activity. For a complete description of Connector data, see the Connectors page.

The Connector table shows the following fields for each connector.




The Connector's name.  


Connector status, such as Running, Stopped, Paused, Completing.

Docs Sent  

The number of documents found in the current Connector run.

Outstanding Docs  

The number of documents for which the Connector has yet to receive acknowledgment from the index.

Last Scan Count  

The number of documents processed on the last Connector run. 

System Events

The System Events table shows a condensed version of event activity. For a complete description of events, see the System Events page.



Event ID 

The unique ID number of the event.  Note that ID numbers can cover multiple projects and nodes, so they do not always appear sequential when viewed within a single project. 


This column indicates the *log4j* level of the event.  


Indicates where the message originated within AIE.


A brief event description. 


The date/time the event occurred. 

Acknowledging Events

New events appear highlighted until you acknowledge them.

To acknowledge an event:

  1. Click on the row containing the event and select Acknowledge from the menu (you can also view Event Details). The Acknowledge Even dialog box appears. Acknowledge Event
  2. Enter your username and a reason in the Acknowledgement area and click Acknowledge.

Multi-Partition Monitoring

Events such as an optimize or index delete appear to be single actions, but are executed once per partition across all nodes of the project. As a result, they generate multiple event messages.

Index Status

By default, the Index Status area shows descriptive statistics for main AIE index.  To view a different index, click the downward pointing arrow in the Index table header, and select the desired index. 




Indicates whether nodes associated with the selected index are healthy or down. 


Shows the type of security.

Indexed Documents

The total number of indexed documents.

Number of Partitions

The total number of partitions in the index.


Size of the index file in bytes.

Searchable Documents

The number of indexed documents that are searchable.


Shows the number and type of duplicate indexes. Types are Write To, Replicate To, and Share To. See Configure the Index for additional details.


Shows which Write To index is currently the master index. A value of mixed indicates that the master index is spread across multiple nodes.

Query Count

Queries processed since restart.


The performance graph shown is the same graph that appears on the Performance Monitoring page.
