Monitoring a Kubeless Function

When we have successfully deployed our Kubeless function, we then need to monitor our function. This can be achieved with the kubeless function top command. This command will provide us with the following information:

• NAME: The name of the Kubeless function
• NAMESPACE: The namespace of the function
• METHOD: The HTTP method type (for example, GET/POST) when invoking the function
• TOTAL_CALLS: The total number of invocations
• TOTAL_FAILURES: The number of function failures
• TOTAL_DURATION_SECONDS: The total number of seconds this function has executed
• AVG_DURATION_SECONDS: The average number of seconds this function has executed
• MESSAGE: Any other messages

The following is the kubeless function top output for the hello function:

$ kubeless function top hello

The output will be as follows:

Now that we've monitored the function...
