Lifecycle Query Engine
(LQE) provides detailed statistics that you can use to analyze the performance of the server and
queries. You can use this information to identify performance issues and take corrective actions, or
to make decisions about improvements.
Procedure

On the LQE Health Monitoring page at
https:<host_name>:<port>/lqe/web/health/overview,
click Statistics in the menu.
If you deployed LQE across several nodes, in the Node Statistics
section select a node from the list and see the associated details, such as data and system
information, and memory usage. You can also focus on a specific partition to see data for artifacts,
historical data, artifact type data, or internal metadata.

Queries in the menu.
In the
Node Queries section, you can view details about a particular
point in the chart by hovering over the point.

will be listed on the Blocked Queries page.
- To unblock a query, click the Unblock action in the list.
