Transmission Control
Name | Data Type | Description |
---|
Discover Edge Nodes | Boolean | A writeable tag to request the BIRTH sequence for any new Edge Nodes to be published and the info tags created in the Transmission Info folder. |
Discover Edge Nodes Required | Boolean | A tag indicating there are new Edge Nodes present on the gateway that have not birthed yet and a Discover Edge Nodes request is required |
Last Refresh | DateTime | The time at which the last refresh request was completed |
Refresh | Boolean | A writeable tag to request a MQTT Transmission refresh. This will force all Edge Nodes to disconnect and reconnect resulting in the sending of NDEATH, NBIRTH and DBIRTH messages |
Transmission Info
Name | Data Type | Description |
---|
Refresh Required | Boolean | A tag indicating that new tags have been identified by Transmission and a refresh is required. The refresh can be accomplished with a full refresh of Transmission or by refreshing the individual Edge Node affected |
Transmitters
For each Transmitter, a tag tree will be created with the tag path of TransmitterName > Tag Path > GroupID > EdgeNodeID
Name | Data Type | Description |
---|
Largest Mesg Xmit (bytes) | Long | The largest message size in bytes sent by the Edge Node since the last time the metrics were reset via the Edge Node Reset Metrics tag |
Largest Mesg Xmit Timestamp | DateTime | The time at which the largest message was sent by the Edge Node since the last time the metrics were reset via the Edge Node Reset Metrics tag |
Last Refresh | DateTime | The time at which the last Edge Node refresh request was completed |
Refresh Edge Node | Boolean | A writeable tag to request a refresh of the Edge Node. This will force the Edge Node to disconnect and reconnect resulting in the sending of NDEATH, NBIRTH and DBIRTH messages |
Refresh Required | Boolean | A tag indicating the new tags have been identified by Transmission for this Edge Node and a refresh is required. |
Reset Metrics | Boolean | A writable tag to reset the metrics for this Edge Node |
Total Bytes Xmit (bytes) | Long | The number of bytes sent by the Edge Node since the last time the metrics were reset via the Edge Node Reset Metrics tag |
Total Mesg Xmit | Long | The number of messages sent by the Edge Node since the last time the metrics were reset via the Edge Node Reset Metrics tag |
MQTT Client
Name | Data Type | Description |
---|
Command Latency (ms) | Long | The amount of time for a test MQTT command message to be sent and received back by the MQTT Client |
Enable Latency Check | Boolean | Writeable tag to enable command latency checking for each MQTT Client |
MQTT Client ID | String | The Client ID for the MQTT Client |
Offline DateTime | DateTime | The last time at which the MQTT Client successfully disconnected from the MQTT Server |
Online | Boolean | A read-only tag showing the connection status of the MQTT Client |
OnlineDateTime | DateTime | The last time at which the MQTT Client successfully connected to the MQTT Server |
Primary Host ID | String | The Primary Host ID configured for this MQTT Client |
Target Server URL | String | The URL of the target MQTT Server to connect to |
History Store
Name | Data Type | Description |
---|
Disk Used | Long | Created if the History Store type is Disk_Backed and shows the memory used since last module restart. This parameter will never go to zero for the following reasons: The initial config of the DB will contain empty seeded tables based on the number of edge nodes and devices (table per edge node and per device) and at least one metadata table. Flushed rows are marked for deletion and will actually be deleted from the DB on its internal schedule. This is to minimize the writes on a flash/SSD drive.
|
Memory Used | Long | Created if the History Store type is In_Memory and shows the memory used since last module restart |
For each Transmitter, a tag tree will be created with the tag path of HistoryStoreName > GroupID > EdgeID and/or > DeviceID
Name | Data Type | Description |
---|
Metrics Percentage Used | Float | Number of Edge Node or Device level tag change events stored as a percentage or the configured Edge Node or Device Tag Capacity |
Metrics Stored | Long | Number of Edge Node or Device level tag change events stored |
Records Percentage Used | Float |
|
Records Stored | Long | Number of Edge Node or Device level records stored |
