Step 3: Display Detailed Component Environmental Information

Action

To display detailed environmental status information about a component, use the following CLI command:

user@host> show chassis environment component-name

Sample Output

The command output displays the temperature of the air passing by the component, in degrees Centigrade. It also displays the total percentage of CPU, interrupt, heap space, and buffer space being used by the component processor, including the total DRAM available to the component processor. The command output displays the time when the component started running and how long the component has been running. A short uptime can indicate a problem with the component.

For examples of sample output, see the JUNOS System Basics and Services Command Reference.

Figure 26 lists the operational mode CLI commands that display more detailed information for each router and platform component.
