Monitoring and managing the performance of Lifecycle
Query Engine
You can monitor and manage the performance
of Lifecycle
Query Engine by
viewing status in the dashboard, responding to issues that are identified,
and configuring properties that impact the responsiveness of queries
and server performance.
Monitoring Lifecycle Query Engine performance
When you log in to Lifecycle
Query Engine,
you can quickly assess the overall status by viewing information in
the various widgets on the Home page. You can view high-level status
of data sources, nodes, the query service, and backups. If issues
need to be addressed, such as errors with data sources, you can click
to see the details and take the appropriate actions.
Improving the responsiveness of Lifecycle Query Engine queries
When the query activity is high,
the load on the server can affect the responsiveness of the queries.
As an administrator, you can take several measures to improve the
resiliency of Lifecycle
Query Engine and
the responsiveness of queries. For example, you can define limits
for running queries, enable query caching, or enable load shedding.
Managing Lifecycle Query Engine nodes
If you installed and deployed Lifecycle
Query Engine across
several nodes, you can use the LQE Nodes page to view the status and
performance details for each node. You can also modify the configuration
for a specific node.
Improving Lifecycle Query Engine performance
As an administrator, you might need
to address performance issues that are not related to any of the query
service or Lifecycle
Query Engine node
configurations. In these situations, you can review and update several
advanced properties.
Analyzing Lifecycle Query Engine server statistics Lifecycle
Query Engine provides
a detailed analysis of the statistics that are gathered about the
performance of the server and queries. You can use this information
to identify issues with performance and take corrective actions, or
to make decisions about improvements.
Setting up Lifecycle Query Engine event notifications
You can configure Lifecycle
Query Engine to
send email notifications whenever certain types of events occur. For
example, if a data source becomes unavailable or if a node goes offline,
you are notified and can take the appropriate corrective action.
