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.

Results returned by the health command vary based on the command target and Flex System chassis type where the command target is installed.
  • Flex System Enterpise chassis command target: For the Flex System Enterpise chassis 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 chassis, unless the state reported by the chassis itself is higher.
    • OK - All monitored parameters are within normal their operating ranges.
    • System level - There are currently active minor warnings or system events, but no critical or major events are active.
    • Non-critical - There are currently active major warnings or system events, but no critical events are active.
    • Critical - One or more critical events are currently active.
  • Lenovo Flex System Carrier-Grade chassis command target: For the Lenovo Flex System Carrier-Grade chassis 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 chassis, unless the state reported by the chassis itself is higher.
    • OK - All monitored parameters are within normal their operating ranges.
    • Minor - There are currently active minor warnings or system events, but no critical or major events are active.
    • Major - There are currently active major warnings or system events, but no critical events are active.
    • Critical - One or more critical events are currently active.
  • Compute node command target: For the compute node command target, one of the following health states is returned for all chassis types. 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.
    • OK - All monitored parameters in the chassis are within normal their operating ranges.
    • Non-critical - There are currently active warnings or system events, but no critical events are active.
    • Critical - One or more critical events are currently active.
  • Command targets other than a chassis or compute node: For command targets other than a compute node, one of the following health states is returned for all chassis types.
    • OK - All monitored parameters are within normal their operating ranges.
    • System level - There are currently active minor warnings or system events, but no critical or major events are active.
    • Non-critical - There are currently active major warnings or system events, but no critical events are active.
    • Critical - One or more critical events are currently active.
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 (Telco major/minor event), Normal symbol for normal system event (Telco OK event)
  • SNMP: Critical/Bad, Warning (Telco major/minor event), Good (Telco OK event)
  • CLI: Critical, Non-critical (Telco major/minor event), 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.
