Missing Assets

In the Axeda Platform, the concept of "Missing" means that an asset cannot be contacted, for whatever reason. The Platform has a scheduled task, called the MissingDevicesTask, that checks for assets that have missed regular contacts ("ping rate") for a specified period of time or have missed a specified number of regular contacts (configured in the Missing Assets step of the Model wizard). These assets may be running an Axeda Agent or wireless assets that are set up to poll the Platform. For these assets, the Missing Assets page shows those assets that the Missing Devices task has determined meet the configured criteria for "Missing".

Note: For an asset to be listed as missing, its model must be configured to go missing, as defined in the Model Wizard - Missing Assets step.

For assets running Axeda IDM Agents that are Occasionally Connected, the MissingDevicesTask detects when these assets are offline and changes their status to Missing. When the assets reconnect, their status returns to Online.

For AWP assets that do not poll the Platform or poll very infrequently and are enabled for shoulder-tap messaging, the MissingDevices task checks the shoulder tap messaging table for those assets that meet the "missing" criteria. A shoulder-tap asset is considered "missing" if the Platform has exhausted the maximum number of retries allowed. For more information about shoulder-tap messaging, refer to Shoulder Tap Messaging for AWP Assets - definition.

For M2M assets that do not poll at all but can respond to a Shoulder Tap message ("contactable" assets) through the Axeda Codec Server, the Last Contact Time updates depend on how the codec handles communications with the assets. Refer to the Axeda® Codec Developer's Kit Guide for complete information.

Notes: The MissingDevices task checks for missing assets based on a schedule set in the Platform. For example, the Platform may be set to check for missing assets every 30 minutes and display the results; if this is the case, then the table updates its list of missing assets every 30 minutes.

If rules are configured to run when a missing asset returns, the rules are generated the next time the Agent running on the asset contacts the Platform. For wireless assets that poll the Platform, the rules are generated the next time the asset polls the Platform. For assets that do NOT poll the Platform, the rules are triggered when the asset responds to a shoulder tap message (as long as the codec forwards the response to the Platform).

Muted assets are not included in the Missing Devices calculation.

Procedures from this page

From this page, you can filter the list of assets shown; add selected assets to your Watch list; view information and properties for an asset. Click the title of a procedure to display it; click the title again to hide it:

How to filter the Missing list

Click Filters to show the filter boxes.
To view all assets to which you have privileges, click Clear without typing any search values. To narrow your search, do the following.

In the box above the Name column, type all or part of the name of the asset(s) you want to find. (The Platform will return all names that contain the characters you specified.)
In the box above the Model column, select the asset model to include in the search.
In the box above the Organization column, select the organization to include in the search.

Click Filter.

The Platform finds all assets that contain the search value(s) defined and shows only those assets in this table.

How to add assets to the Watch list

For an asset shown in the table, select the check box after the Last Contact column. To add all assets shown to your Watch list, select the check box in the table header. This automatically selects all check boxes in that column. (You can unselect assets if you don't want to add them all to the Watch list.) Skip to step 3.
Repeat step 1 for each asset you want to add to your Watch list.
Click Add Checked to Watch List.

How to view asset information and properties

From the table, select the name of the asset.

The Asset dashboard appears with information and properties for that asset.

Tips

o Select an option from the Jump to list to see more information or actions for the asset If the asset is muted, you will be restricted to viewing only those pages that do not contain functionality that will result in communications to the muted asset. If the asset is unmuted, all pages to which you have privileges are available. For example, click Available scripts to see a list of all scripts registered for this asset as well as the names of the script authors and descriptions of each script. The options in this list vary from asset to asset.

o The maximum number of rows supported for returning Platform search results for this type of table is defined in your user preferences, Items Per Page setting (Long table or Short table).

o Use $image\icon_refresh.gif$ (Refresh link) beside the table navigation tools to refresh the page with the latest Platform results. (Browser Refresh tools do not update the table.)
