Rhino provides monitoring facilities for capturing statistical-performance data about the cluster, using the client-side application rhino-stats.
This application connects to Rhino using JMX, and samples requested statistics, in real time.
You can display extracted statistics in tabular-text form on the console, or graphed on a GUI using various graphing modes.
When correctly configured, monitored, and tuned — using Rhino’s performance-monitoring tools — Rhino SLEEs will surpass industry standards for performance and stability. ---
For service developers and administrators
Much of the statistical information that rhino-stats gathers is useful to both service developers and administrators:
-
Service developers can use performance data, such as event-processing time statistics, to evaluate the impact of SBB-code changes on overall performance.
-
Administrators can use statistics to evaluate settings for tunable performance parameters. For example, the following can help determine appropriate configuration parameters:
| Parameter set type | Tunable parameters |
|---|---|
Object pools |
Object pool sizing |
Staging threads |
Staging configuration |
Memory database sizing |
Memory database size limits |
System memory usage |
JVM heap size |
