Saving data

Health Center can save the data that it is currently analyzing to a .hcd file on the hard disk.

The .hcd file can be opened by the Health Center at a later date without the need for a live connection. The file contains data showing what the system looked like at the time the data was saved. The file does not need to be opened by the Health Center that created it. The file can be passed to another installation of the same version for analysis. For more information, see Opening files from disk.

Saving data to disk

To save data to disk, select File > Save Data.

You are prompted to enter a file name and location for saving the data.

The amount of disk space used to export data is configurable. By default, the disk space is 300 MB. This means that only the most recent 300 MB of data read by the Health Center is available to save. The quantity of information produced by the monitored application determines the time duration included in the 300 MB of data. For example, an application producing little information might record the last 10 hours of trace data in 300 MB of space. An application producing much information might only record the last 10 minutes of data.

To change the amount of disk space used to save data, use the disk space management option under Preferences > Data Storage Settings. To save all the data read by the Health Center, clear this option.

CAUTION:
If you remove the limit on the file size, the file might grow until you run out of disk space.

All the data currently available is exported. If you cropped the data displayed by dragging to select only a particular time interval, then the cropping settings are lost when you import the file. If you have enabled Sliding window truncation, then data outside of the sliding window you selected is exported if the data has not yet been removed from the disk. The exported data is available when you import the file later.
