Advanced Settings

The Advanced Settings tab (System > Advanced Settings) provides administrators with global server configuration parameters that control retention, thresholds, execution, and storage options in XLServer.

These parameters apply system-wide across all projects.

Retention Settings (in days)​

XLServer continuously collects and stores metrics for monitoring and analysis.
To prevent repository database growth, old data is automatically purged based on retention periods.

Default retention values:

  • Server Metrics Retention: 30 days
  • Storage Metrics Retention: 30 days
  • Log Retention: 7 days
  • Audit Retention: 30 days

💡 Administrators can modify these values to balance data availability vs. repository size.

Threshold Settings (percentages)​

Thresholds define limits at which XLServer raises notifications or triggers incidents (if alerting is enabled).
They are defined as warning and critical levels.

Default thresholds:

  • Root Disk Warning Threshold: 80%
  • Root Disk Critical Threshold: 90%
  • Datastore Usage Warning Threshold: 75%
  • Datastore Usage Critical Threshold: 85%
  • Datastore Fragmentation Threshold: 20%

⚠️ Review thresholds to align with your SLA and infrastructure capacity.
Exceeding critical thresholds may result in degraded performance or service disruption.

Execution Settings​

These parameters tune the Task Executor Pool, which is the internal engine that queues and executes jobs in parallel.

Default values:

  • Thread Pool Executor Maximum Size: 4
  • Thread Pool Executor Core Size: 1

📊 Use System > Monitoring to observe job executor metrics (task queue, wait time, failures).
Adjust these values based on appliance resources and workload concurrency.

Storage Options​

Datastore storage behavior can be customized:

  • Enable Compression – When checked, datastore-level compression is enabled for all projects.
    By default, compression is disabled.

💡 Enabling compression reduces storage usage at the cost of additional CPU overhead.
Recommended for environments with limited disk space.
