Example 1 with DataSource

use of org.collectd.api.DataSource in project jcollectd by collectd.

the class PacketWriter method write.

public void write(PluginData data) throws IOException {
    String type = data.getType();
    writeString(Network.TYPE_HOST, data.getHost());
    writeNumber(Network.TYPE_TIME, data.getTime() / 1000);
    writeString(Network.TYPE_PLUGIN, data.getPlugin());
    writeString(Network.TYPE_PLUGIN_INSTANCE, data.getPluginInstance());
    writeString(Network.TYPE_TYPE, type);
    writeString(Network.TYPE_TYPE_INSTANCE, data.getTypeInstance());
    if (data instanceof ValueList) {
        ValueList vl = (ValueList) data;
        List<DataSource> ds = _types.getType(type);
        List<Number> values = vl.getValues();
        if ((ds != null) && (ds.size() != values.size())) {
            String msg = type + " datasource mismatch, expecting " + ds.size() + ", given " + values.size();
            throw new IOException(msg);
        }
        writeNumber(Network.TYPE_INTERVAL, vl.getInterval());
        writeValues(ds, values);
    } else {
    // XXX Notification
    }
}

Example 2 with DataSource

use of org.collectd.api.DataSource in project jcollectd by collectd.

    String line;
    while ((line = reader.readLine()) != null) {
        DataSet ds;
        ds = DataSet.parseDataSet(line);
        if (ds != null) {
            String type = ds.getType();
            List<DataSource> dsrc = ds.getDataSources();
            this._types.put(type, dsrc);
        }
    }
}

Example 3 with DataSource

use of org.collectd.api.DataSource in project jcollectd by collectd.

            instance = vl.getTypeInstance();
        }
    }
