This node lets you call one of the functions provided by systeminformation. The result of each call will be returned as msg.payload.
There are two ways to select the function to be called:
$3
You may configure the to-be-called function via the nodes property editor.
style="min-width: 432px; width: 432px; align: center; border: 1px solid lightgray;"/>
Functions are arranged in groups, following the systeminformation documentation.
In case a function expects additional parameters, those may be defined as required.
Additionally, the node may be configured to observe the selected function by polling at a given rate. If polling is enabled, you may decide to let the node emit a msg only if the function call returned changed values.
$3
You may trigger the call of a
systeminformation function as well by sending to the node a msg that is configured accordingly:topic: name of the systeminformation function to be called.
payload: optional with parameters to be passed to the function. The keys of the objects properties have to match the names of the parameters as defined by the systeminformation documentation, e.g:
``
{
topic: 'versions',
payload: {
apps: 'npm, php, postgresql'
}
}
> The dynamic mode may be used in addition & parallel to a static configuration, as shown in the provided example.
