Readers: | Number of tags being read from this DataSet (each tag will be a Reader). |
Writers: | Number of tags being written to this DataSet (each logging tag is a Writer). |
HDB Files: | Number of .hdb2 files in this DataSet. |
Last File: | Gives the date of the most recently created HDB file. |

Directory: | Path where the files are stored for this DataSet. |
Rollover: | If logging continues this will show the date/time the DataSet is configured to Rollover (create a new file). If logging is stopped and resumed after the time passes then Rollover will occur when logging starts. |

Arrow Down 
On the DataSet Panel
Roll-Over | Forces a file Roll-Over to happen immediately. |
Roll-Up | Forces a Roll-Up if it is configured for this DataSet and files are available to act on. |
Obsolete Tags | Pulls up the Obsolete Tags search menu. Tags can be made obsolete to reduce the tag license count. Obsolete tags still consume storage space, but they cannot be accessed. The Obsolete Tags option is for the Ignition Module and certain custom-made collectors that cannot omit tags, they either send everything or nothing. Make some tags obsolete so that you only pay for the data in use. |
Refresh File List | Refreshes the list of .hdb2 files displayed if a file has been copied into or removed through the directory. |
Validate All Files | Performs a validation on all files in the DataSet. |

DataSets that have not received any data within the specified amount of time are indicated by a red dot in the top left hand corner of the DataSet tile. Learn how to adjust the time allotment setting, to become aware of connection issues as soon as possible.
