_Stat_event_0
The data point element saves the total performance (the amount of all Event Manager connections) per message.
The first table shows the SndTotal, RcvTotal, Snd and Rcv elements. Since Snd and Rcv contain many elements, these elements are described in an own table.
| Data point element | Type | Description |
| SndTotal | unsigned | How many messages were sent in the last interval (altogether). (SndTotal) |
| RcvTotal | unsigned | How many messages were received in the last interval (altogether). (RcvTotal) |
| Snd | The elements of Snd are described in the table below. | |
| Rcv | The elements of Rcv are described in the table below. |
| Data point element | Type | Description |
| SYS_MSG | unsigned | General system messages which the managers send to each other |
| SYS_MSG_NAMESERVER | unsigned | ID of the data point |
| DP_MSG_CONNECT | unsigned | Corresponds to dpConnect() which registers the work() function to be called when the values of data point attributes are changed. |
| DP_MSG_HOTLINK | unsigned | Notification for a dpConnect() |
| DP_MESSAGE_VC | unsigned | Corresponds to a dpSet() (which assigns values to data point attributes or creates data point configs) and to dpSetTimed() (which assigns values and source time to original attributes that can be modified by user) |
| DP_MESSAGE_REQUEST | unsigned | Request for an answer. Corresponds to a dpGet() which reads values of data point attributes. |
| DP_MESSAGE_ANSWER | unsigned | A general answer for a dpGet() |
| DP_MSG_IDENTIFICATION | unsigned | Data point identification |
| DP_MSG_TYPECONTAINER | unsigned | Type container |
| DP_MSG_MANIP_DP | unsigned | Creating data points |
| DP_MSG_LOCK | unsigned | Locks configs |
| DP_MSG_UNLOCK | unsigned | Unlocks configs |
| DP_MSG_CMD_NEW_DEL_DP | unsigned | Information about new data points |
| DP_MSG_SIMPLE_REQUEST | unsigned | Corresponds to dpGet() |
| DP_MSG_ASYNCH_REQUEST | unsigned | Corresponds to dpGetAsynch() which reads values of data point attributes at particular source time. |
| DP_MSG_PERIOD_REQUEST | unsigned | Corresponds to dpGetPeriod()which queries data point attributes over a specific period. |
| DP_MSG_ALERT_VC | unsigned | Corresponds to alertSet() which allows to set data point attributes. For example acknowledgements are executed via this element. |
| DP_MSG_ALERT_CONNECT | unsigned | Corresponds to an alertConnect() which registers the work() function to be called when there are existing alerts. |
| DP_MSG_ALERT_HL | unsigned | Information(answer) to an alertConnect() |
| DP_MSG_ALERT_DISCONN | unsigned | Corresponds to an alertDisconnect() which logs off the work() function call (the work function is not called anymore) |
| DP_MSG_ALERT_TIME_REQUEST | unsigned | Corresponds to an alertGet() |
| DP_MSG_ALERT_PERIOD_REQU | unsigned | Corresponds to an alertGetPeriod() which writes values of alert attributes (of data point elements)for which alerts were saved in the database during a defined period. |
| DP_MSG_FILTER_REQ | unsigned | Corresponds to a dpQuery() which queries attribute values with the aid of SQL statements. |
| DP_MSG_FILTER_CONNECT | unsigned | Corresponds to a dpQueryConnectAll() (which initializes a registration to a workfunc()that is called when attributes are changed as well as when data points are created) or to a dpQueryConnectSingle() which works like dpQueryConnectAll but returns only one line when attributes are changed. |
| DP_MSG_FILTER_DISCONNECT | unsigned | Corresponds to dpQueryDisconnect() which ends a registration for a work function. |
