Node.js Overview
The Node.js Overview is the top-level display for the Node.js Monitor, which provides a good starting point for immediately getting the status of all your connections on your Data Server. You can select the RTView DataServer for which you want to see data and easily view the current data for that DataServer including:
| • | The total number of active alerts for the selected DataServer, including the total number of critical and warning alerts. |
| • | The total number of modules. |
| • | The total number of processes across all instances. |
| • | The maximum process lag across all instances. |
| • | The total number of expired workers. |
| • | A visual list of the top 10 hosts based on CPU percentage and rate of requests on your connected DataServer. |
You can hover over each region in the upper half of the Overview to see more detail. You can also drill down to see even more detail by clicking on each respective region in the Overview. For example, clicking on the alerts in the CRITICAL and WARNING alerts region opens the Alerts Table by Components display.
The bottom half of the display provides a trend graph for a selected connection/host combination. You can hover over the trend graph to see the values at a particular time. You can specify the time range for the trend graph and view data based on a log scale, which enables visualization on a logarithmic scale and should be used when the range in your data is very broad.
