Taking a Snapshot

Many times the best way to send diagnostic information to INTEG is to send us a Snapshot. A Snapshot is a zip file containing all of the files from the JNIOR.

When a Snapshot is taken the Support Tool will make a telnet connection, run a few diagnostic commands and then download all of the files. The diagnostic commands that are executed will be logged to the snapshot.log file.

There are two commands that will generate files that are not normally in the file system.

The first in the iolog command. The iolog command will generate a jniorio.log file. This file shows the past 512 digital input transitions as well as the past 512 relay output transitions. Up to 16 relay outputs will be shown in the log. The relays on the expansion modules will be logged as well.

The second command is the netstat -c command. This command generates a network capture file in the temp directory. The network capture file can be loaded in a desktop application called wireshark. This file will grow up to 512Kb. The duration of time covered by the file depends on the amount of traffic that the JNIOR handles. Optionally filters can be applied to the capture buffer to limit the types of traffic that are logged.

To take a snapshot follow these steps:

Open the Support Tool. Go to the Snapshot tab.

Click on ‘Take Snapshot’.

Answer ‘Yes’ to the Snapshot confirmation dialog

Select the JNIOR you want to take a Snapshot from and click ‘Ok’.

Once your snapshot is compete find it on the left. It should be made visible once it is complete. Right click on the Snapshot file and select ‘Show in folder’. You could also expand the zip archive in the tree view or double click it to open in your loaded Archive application.

Taking a Backup

It is always a good idea to take backups of devices. Personal pictures, work documents, and even the JNIOR. There is another aspect of taking a backup of the JNIOR that can prove very useful. That is that a backup can become an update project. The update project can then be used to restore the same unit to a point in time or to clone a JNIOR. This means that you can take a backup and then make one or more other JNIORs appear and behave exactly the same.

Where can I find the backup feature? The Backup feature is under the Snapshot tab.

How is a Backup different than a Snapshot? The backup differs from a snapshot in a two ways. The most important difference is that an update project will be created. The other difference is that log files are not captured. A snapshot is used to capture log files to submit to INTEG to help debug any issue you may be having.

The Backup procedure Click ‘Take Backup’ in the Snapshot Tab

Take Backup Button You will be shown a prompt that lets you know what is about to happen and to make sure you want to continue.

Backup Confirm Info Clicking ‘Yes’ will provide you with a dialog allowing you to select which unit you want to backup.

JNIOR selection dialog box When the backup has finished you will be prompted for a name. Give the backup a meaningful name. That name might be the unit name followed by a date string or it may be a name describing the job function that the JNIOR is performing.

Backup Naming dialog box Lastly you will be prompted to open the Backup or Update Project in the Update Tab.

Open Backup as Update Project If you click ‘No’, you can open the Update Project at any future point in time. Just go to the Update tab and click ‘open project’ and select the backup.

The following is the backup update project that was created.

Edit Update Project That, is the backup procedure. Congratulations, you can now use this backup to restore this unit back to this point in time or use it to configure other JNIORs to perform the same task.

Note

After successfully cloning a JNIOR configuration, since it will copy the EXACT configuration of the other JNIOR, make sure you go through and change any settings that shouldn’t be the same. This means any references to external devices should be checked for IP changes.
