You can install StatsD to monitor the performance of your system in real time.
Figure 2.1, “StatsD Monitoring Protocol” shows a simple flow chart that depicts the StatsD monitoring protocol.
StatsD is a fast, lightweight system monitor and can use many third party tools for storing the statistics it collects (e.g. Graphite) and for displaying the statistics as graphs (for e.g. using Grafana).
Examples of metrics that StatsD can monitor include:
- Number of report pages rendered
- Number of JDBC rows accessed
- Servlet response time
- Number of Job Engines
- System RAM and CPU loads
