Troubleshoot performance issues

Resolve slow response times and performance degradation in agent management by optimizing serverclass configuration and API usage.

Condition

Performance issues in agent management can cause slow responses from the deployment/server/clients endpoint. The following symptoms indicate a performance issue:

The response from the endpoint deployment/server/clients takes more than 30 seconds.
The Agent Management home page takes more than 30 seconds to load.
Searching by host name or app takes more than 30 seconds to complete.
The list of matched agents for server class takes more than 30 seconds to load.

Solutions

Use the following solutions to resolve performance issues in agent management:

Reload agent management periodically
Over time, agent management can slow down. Reload agent management periodically to improve performance.
Change the index retention period
Reduce the index retention period for the _dsphonehome index to improve performance when you have many agents that phone home frequently.
Change the phone home interval on every agent
Increase the phoneHomeIntervalInSecs value to reduce the frequency of agent check-ins and improve performance.
Reduce serverclass whitelist and blacklist count
Optimize serverclass allow list and deny list configuration by using regex patterns, shared attributes, machine type filters, and removing stale entries. Serverclass configuration is a known bottleneck because each list entry results in heavy regex matching operations.
Use lookup cache when Deployment Server 10.2 or higher is available
Enable lookup cache for improved performance in Deployment Server 10.2 or higher.
Use API endpoints that show agents by ID
Use API endpoints that retrieve specific agent information by ID instead of loading the entire agent list to improve performance.
