About this task
You can monitor Index Load in the following ways:
- Interactively, by using the Index Load status command while indexing.
- After running Index Load, using the search administration logger.
Procedure
- Use the metrics that are displayed by the Index Load status
command while indexing to help refine tuning parameters and improve
performance throughput:
- Go to the following URL: http://hostname:port/search/indexload/status.
The status report is displayed and shows its metrics.
For example:
- Review the status report and further adjust the tuning
parameters in this task accordingly.
The status report
contains the following considerations:
- The overall read rate and indexing rate.
- The batch queue size in memory with the high water mark, showing
the peak memory consumption.
- The average document width and size in bytes.
- The cumulative flush and commit time.
- The time that the system resources are utilized. That is, the
CPU time and heap memory.
- The index data directory statistics with related Solr configurations.
- Use the search administration logger to read Index Load
statuses from the admin.log file.
