Help with agent_based and rulesets

Hi,

First of all, thank you very much for the help

I am developing a new integration with proxox.
I have taken the data from the VMs and I want it to have rule to define the status of OK, WARN, CRIT… according to the state of the machine.
I know that the problem is with the integration with the rule because if I leave it without the integration everything seems to go correctly.

The error is when I do a service discovery:

Well, this is the definition of the rule:
(I don’t pass the whole function as the above is “nonsense”)

        elements={
            "powered_on": DictElement(
                parameter_form = ServiceState(
                    title = Title("Powered ON"),
                    prefill=DefaultValue(ServiceState.OK),
                    help_text = Help(
                        "Check result if the VM is powered on"
                    ),
                ),
            ),
            "powered_off": DictElement(
                parameter_form = ServiceState(
                    title = Title("Powered OFF"),
                    prefill=DefaultValue(ServiceState.WARN),
                    help_text = Help(
                        "Check result if the VM is powered off"
                    ),
                ),
            ),
            "unknown": DictElement(
                parameter_form = ServiceState(
                    title = Title("Powered OFF"),
                    prefill=DefaultValue(ServiceState.UNKNOWN),
                    help_text = Help(
                        "Check result if the VM is powered off"
                    ),
                ),
            ),
        }

this is the check function of the vm:

def check_proxmoxve_qemu(item, params, section):
    data = section.get(item)

    if data is None:
        yield Result(
            state=params["unknown"],
            summary=f"VM with ID {item} no longer exists"
        )
        return
    
    qemu_state = data['State']
    qemu_name = data['VM Name']

    if qemu_state == "running":
        state_code = params["powered_on"]
    elif qemu_state == "stopped":
        state_code = params["powered_off"]
    else:
        state_code = params["unknown"]

    yield Result(
        state = state_code,
        summary = f"{qemu_name} is {qemu_state}"
    )

and the Check Plugin function:

check_plugin_ometemp = CheckPlugin(
    name = "proxmoxve_qemu",
    service_name = "VM %s",
    discovery_function = discover_proxmoxve_qemu,
    check_function = check_proxmoxve_qemu,
    check_default_parameters = {
        "powered_on": State.OK,
        "powered_off": State.WARN,
        "unknown": State.UNKNOWN
        },
    check_ruleset_name = "proxmoxve_qemu",
)

There is a syntax error somewhere, according to the error message the error is in line 1.

Since this is unfortunately not your complete script, it is not possible to see exactly where the error is.

You should check your syntax and maybe run a linter.

Hi!

I found the problem, it should be written as State(params[‘parameter_name’])

it looks like this:

    if qemu_state == "running":
        state_code = State(params["powered_on"])
    elif qemu_state == "stopped":
        state_code = State(params["powered_off"])
    else:
        state_code = State(params["unknown"])
