Hardware Data and Test Results
This topic provides information about the results of the tests that Paragon Automation executes to determine the health and functioning of the device hardware.
Overview
The Hardware accordion displays the hardware data and results of the tests that Paragon Automation executes. These tests determine the health and functioning of a device hardware. You can also view events (alerts and alarms), if any, for the device on the Hardware accordion and on the Hardware Details for Device-Name page.
To access the Hardware accordion, navigate to the Observability > Health > Troubleshoot Devices page. Click a device name to access the Device-Name page. Click the Hardware (accordion) in the Overview tab.
The top-right corner of the accordion displays the overall health of the device's hardware. The various states are:
-
Healthy—The device's hardware (PSUs, fans, line cards, CPU, and memory) and temperature (of the Routing Engine, Routing Engine CPU, PSM, and chassis) is healthy.
-
Being Monitored—The health of the device is being monitored.
-
Action Needed—The device's hardware and temperature have issues that you must address.
-
Urgent Action Needed—The device's hardware and temperature have issues that must be addressed immediately.
Table 1 lists the results of the hardware tests.

Performance Graphs
The graphs on the Hardware Details for Device-Name page display the performance of the hardware components. You can also view information on alerts and breaches, if any, on these graphs. Figure 1 shows the graphs for fans in a device.
The fans present in the device are listed on the left of the Fan accordion, in the order of severity of events that have occurred. You can view up to six fans at a time with the fan that is in the most critical state displayed at the top of the list. To view fans that are not listed, click the Select Fans drop-down list and select the fans. However, you must clear a previously selected fan to be able to select another fan.
Click the toggle button next to the name of the fan, to view the performance of the fan in a graph. The graph displays two lines showing the high (in orange) and critical (in red) threshold levels related to the speed of the fan. You can also zoom into a particular portion of the graph to view more information about events that have occurred.
To view the performance of more than one fan on the graph, click the toggle button next to the name of the fan in the Show Fan Speeds list. Details of the fans displayed on the graph are also listed in a table below the graph as shown in Figure 1. You can also click the option buttons on the left of a fan name in the table to highlight the graph for that fan.
You can view the performance of a fan for a week, a day, 3 hours, 1 hour, 30 minutes, or a custom time period. By default, performance for the past 30 minutes is displayed. To change this period, click the Week, Day, 3 hrs, 1 hr, 30 mins, or Custom buttons provided above the graph.
You can view more than 25 data points on a graph related to events (in real time) that have occurred on the fan when you select the 30-minute time period. However, you can only view up to 25 data points related to events when you select a week, a day, 3 hours, 1 hour, or a custom time period (of more than 30 minutes). Data is aggregated to ensure that not more than 25 data points are plotted on the graph at once.
The graph auto-refreshes at an interval depending on the time range for which the information is displayed. See Table 4 for more information. However, you can refresh the graph at any point by clicking the Refresh icon provided above the graph.
You can also click the pop-out button next to the graph to open the graph in a new tab. You can view all customizations that you made on the graph in the parent tab, in the new tab.
The most critical alert (issues and anomalies) is displayed just above the graph and next to the quick chart. To view other alerts, click the link just below the alert. The quick chart displays the performance of the fan that you selected from the Select Fans drop-down list. However, if alerts related to the performance of any fan is generated, the fan with the most severe alert is displayed on the quick chart by default.
Alerts, if any, related to the fan is also displayed on the graph, and in the table below the graph. You can also open the graph in a new tab. When you open a graph in a new tab, you can view the following information in the new tab as well:
-
Alerts related to the fan.
Alerts are refreshed across all open tabs simultaneously, when:
-
An alert is refreshed in any one of the open tabs.
-
The last alert fetched was beyond three minutes.
-
-
List of fans that you toggled to view from the Select Fans drop-down list.
-
Fan that you selected from the table below the graph.
| Time Range | Auto-Refreshed |
|---|---|
| Weekly | Every 16.8 hours |
| Daily | Every 58 minutes |
| Every three hours | Every 8 minutes |
| Hourly | Every 3 minutes |
| Thirty minutes | Every 2 minutes |
| Custom | No auto-refresh |
You can similarly view the graphs and alerts related to the performance of other hardware components and temperature.
