Comands for JSON/Simple-JSON Grafana Plugin added

[marcokaminski]

Some commands have been added to visualize data in Grafana without having to create SQL queries.
For Grafana there are 2 plugins working with the new commands.

In the forum there is a post about it https://forum.iobroker.net/topic/23033/aufruf-modifikation-simpleapi-adapter-iobroker-als-datenquelle-f%C3%BCr-grafana
Issue #17 is then processed.

I had upgraded to version 2.0.3 and adopted the changes from 2.0.4 and 2.0.5.
I have left my changes as version 2.0.3, I hope that's okay.

Very interesting case. Thank you!
Only one improvement could be done: the iteration via all instances with common.getHistory flag set will return all instances that support "history" and there is no need to iterate sql, influx... extra.

function getHistoryInstances() {
    socket.emit('getObjectView', 'system', 'instance', {startkey: 'system.adapter.', endkey: 'system.adapter.' + '.\u9999'}, function (err, doc) {
        if (err) {
            console.error(err);
        } else {
            if (doc.rows.length) {
                var result = [];
                for (var i = 0; i < doc.rows.length; i++) {
                    result.push(doc.rows[i].value);
                }
                result = result.filter(function (adp) {
                    return adp && adp.common && adp.getHistory;
                });
                
                var text = '';
                for (var r = 0; r < result.length; r++) {
                    var name = result[r]._id.substring('system.adapter.'.length);
                    text += '<option value="' + name + '" ' + (settings.dataSource === name ? 'selected' : '') + '>' + name + '</option>';
                }
                $('#dataSource').append(text).select();
                showHideSettings();
            }
        }
        
    });
}

I had searched for such a function, a very good idea. I will implement that today or tomorrow.

[marcokaminski]

I tried to install the function. But I get an empty rows-array when calling

socket.emit('getObjectView', 'system', 'instance', {startkey: 'system.adapter.', endkey: 'system.adapter.' + '.\u9999'}, function (err, doc)

There are instances of adapter history and influxdb.

There are two errors fixed:

function getHistoryInstances(settings) {
    socket.emit('getObjectView', 'system', 'instance', {startkey: 'system.adapter.', endkey: 'system.adapter.\u9999'}, function (err, doc) {
        if (err) {
            console.error(err);
        } else {
            if (doc.rows.length) {
                var result = [];
                for (var i = 0; i < doc.rows.length; i++) {
                    result.push(doc.rows[i].value);
                }
                result = result.filter(function (adp) {
                    return adp && adp.common && adp.common.getHistory;
                });
                
                var text = '';
                for (var r = 0; r < result.length; r++) {
                    var name = result[r]._id.substring('system.adapter.'.length);
                    text += '<option value="' + name + '" ' + (settings.dataSource === name ? 'selected' : '') + '>' + name + '</option>';
                }
                $('#dataSource').append(text).select();
                showHideSettings();
            }
        }
    });
}

@marcokaminski Could you please add infos about these new possibilities also to README nd maybe update the Forum thread?

[Apollon77]

PS: We still need to do a 2.1.0 with these new features once verified working (e.g. via Forum check?)

[marcokaminski]

@Apollon77 For the new commands (search, query) I had already adapted the README.md.
The feature proposed by Bluefox has just eliminated adapter customization for other adapters with history data.
I will announce in the forum post mentioned above, that the changes are now entered in the ioBroker repository and now this repository should be used.

Finalization comments:

• I changed it to get published as 2.1.0
• enhancing tests for the new methods would be great :-)
