oncloud.sql

==================================

This adapter saves state history into SQL DB.

Supports PostgreSQL, mysql, Microsoft SQL Server and sqlite. You can leave port 0 if default port is desired.

MS-SQL:

Use localhost\instance for host and check that TCP/IP connections are enabled. https://msdn.microsoft.com/en-us/library/bb909712(v=vs.90).aspx

SQLite:

is "file"-DB and cannot manage too many events. If you have a big amount of data use real DB, like PostgreSQL and co.

SQLite DB must not be installed extra. It is just a file on disk, but to install it you require build tools on your system. For linux, just write:

sudo apt-get install build-essential

For windows:

c:\>npm install --global --production windows-build-tools

And then reinstall the adapter, e.g:

cd /opt/oncloud
oncloud stop sql
npm install oncloud.sql --production
oncloud start sql

MySQL:

You can install mysql on linux systems:

apt-get install mysql-server mysql-client

mysql -uroot -p

CREATE USER 'oncloud'@'%' IDENTIFIED BY 'oncloud';
GRANT ALL PRIVILEGES ON * . * TO 'oncloud'@'%';
FLUSH PRIVILEGES;

If required edit /etc/mysql/my.cnf to set bind to IP-Address for remote connect.

Warning: oncloud user is "admin". If required give limited rights to oncloud user.

Structure of the DBs

Default Database name is "oncloud", but it can be changed in configuration.

Sources

This table is a list of adapter's instances, that wrote the entries. (state.from)

DB	Name in query
MS-SQL	oncloud.dbo.sources
MySQL	oncloud.sources
PostgreSQL	sources
SQLite	sources

Structure:

Field	Type	Description
id	INTEGER NOT NULL PRIMARY KEY IDENTITY(1,1)	unique ID
name	varchar(255) / TEXT	instance of adapter, that wrote the entry

Note: MS-SQL uses varchar(255), and others use TEXT

Datapoints

This table is a list of datapoints. (IDs)

DB	Name in query
MS-SQL	oncloud.dbo.datapoints
MySQL	oncloud.datapoints
PostgreSQL	datapoints
SQLite	datapoints

Structure:

Field	Type	Description
id	INTEGER NOT NULL PRIMARY KEY IDENTITY(1,1)	unique ID
name	varchar(255) / TEXT	ID of variable, e.g. hm-rpc.0.JEQ283747.1.STATE
type	INTEGER	0 - number, 1 - string, 2 - boolean

Note: MS-SQL uses varchar(255), and others use TEXT

Numbers

Custom queries

The user can execute custom queries on tables from javascript adapter:

sendTo('sql.0', 'query', 'SELECT * FROM datapoints', function (result) {
    if (result.error) {
        console.error(result.error);
    } else {
        // show result
         console.log('Rows: ' + JSON.stringify(result.result));
    }
});

Or get entries for the last hour for ID=system.adapter.admin.0.memRss

sendTo('sql.0', 'query', 'SELECT id FROM datapoints WHERE name="system.adapter.admin.0.memRss"', function (result) {
    if (result.error) {
        console.error(result.error);
    } else {
        // show result
        console.log('Rows: ' + JSON.stringify(result.result));
        var now = new Date();
        now.setHours(-1);
        sendTo('sql.0', 'query', 'SELECT * FROM ts_number WHERE ts >= ' + now.getTime() + ' AND id=' + result.result[0].id, function (result) {
            console.log('Rows: ' + JSON.stringify(result.result));
        });
    }
});

storeState

If you want to write other data into the InfluxDB you can use the build in system function storeState. This function can also be used to convert data from other History adapters like History or SQL.

The given ids are not checked against the oncloud database and do not need to be set up there, but can only be accessed directly.

The Message can have one of the following three formats:

• one ID and one state object
• one ID and array of state objects
• array of multiple IDs with state objects

Get history

Additional to custom queries, you can use build in system function getHistory:

var end = new Date().getTime();
sendTo('sql.0', 'getHistory', {
    id: 'system.adapter.admin.0.memRss',
    options: {
        start:      end - 3600000,
        end:        end,
        aggregate: 'minmax' // or 'none' to get raw values
    }
}, function (result) {
    for (var i = 0; i < result.result.length; i++) {
        console.log(result.result[i].id + ' ' + new Date(result.result[i].ts).toISOString());
    }
});

History Logging Management via Javascript

The adapter supports enabling and disabling of history logging via JavaScript and also retrieving the list of enabled datapoints with their settings.

enable

The message requires to have the "id" of the datapoint.Additionally optional "options" to define the datapoint specific settings:

sendTo('sql.0', 'enableHistory', {
    id: 'system.adapter.sql.0.memRss',
    options: {
        changesOnly:  true,
        debounce:     0,
        retention:    31536000,
        maxLength:    3,
        changesMinDelta: 0.5,
        aliasId: ""
    }
}, function (result) {
    if (result.error) {
        console.log(result.error);
    }
    if (result.success) {
        //successfull enabled
    }
});

disable

The message requires to have the "id" of the datapoint.

sendTo('sql.0', 'disableHistory', {
    id: 'system.adapter.sql.0.memRss',
}, function (result) {
    if (result.error) {
        console.log(result.error);
    }
    if (result.success) {
        //successfull enabled
    }
});

get List

The message has no parameters.

sendTo('sql.0', 'getEnabledDPs', {}, function (result) {
    //result is object like:
    {
        "system.adapter.sql.0.memRss": {
            "changesOnly":true,
            "debounce":0,
            "retention":31536000,
            "maxLength":3,
            "changesMinDelta":0.5,
            "enabled":true,
            "changesRelogInterval":0,
            "aliasId": ""
        }
        ...
    }
});
