health command

This command displays the current health status of the command target. It can also be used to display the alerts that are active for the command target.

You can only specify one command target each time you run the health command.

For the compute node command target, one of the following health states is returned. This state will reflect the highest health state reported by any other component installed in the compute node, unless the state reported by the compute node itself is higher.

For command targets other than a compute node, one of the following health states is returned. For the Flex System Enterprise Chassis, this state will reflect the highest health state reported by any other component installed in the chassis, unless the state reported by the chassis itself is higher.

Note: The various CMM interfaces use different terms to indicate the same condition:
  • Web interface: Critical symbol for critical system event, Attention symbol for non-critical system event, Normal symbol for normal system event
  • SNMP: Critical/Bad, Warning, Good
  • CLI: Critical, Non-critical, OK

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or health command errors for a list of error messages that are specific to the health command.

Table 1. health command.

The command table is a multi-row, four-column table where each row describes a CMM CLI command option: column one lists command function, column two provides a detailed command description, column three shows command-option syntax, and column four lists valid command targets.
Function What it does Command Target (see paths in Command targets)
Display health status Displays the current health status of the command target.
  • Possible return values for the compute node target are:
    • ok
    • non-critical
    • critical
  • Possible return values for other targets are:
    • ok
    • system level
    • non-critical

Example: To display the health status and alerts in a tree structure with time stamps for all components installed in the Flex System Enterprise Chassis, that are valid command targets, while the Flex System Enterprise Chassis is set as the default command target, at the system> prompt, type 
health -l a -f -t

The following example shows the information that is returned from these commands:

system> health -l a -f -t
