Work with Virtual Receiver Logs and Version History

info

All procedures, described in this page, are generic for all Virtual Receivers connected to evalink talos and are done from any instance of a Virtual Receiver.

If there are any specifics of working with Virtual Receiver logs and version history for a particular receiver type, they will be mentioned in the documentation section that is dedicated to that receiver type.

You can access your connected Virtual Receiver records for a particular site by navigating to the Sites > [site] > Receivers tab.

All events for each instance of any Virtual Receiver are recorded into Virtual Receiver logs. For each instance of a Virtual Receiver configured on a site, you can view receiver logs for a set period of time and version history which reflects all the changes to the receiver instance configuration made by evalink talos users.

Logs and version history are maintained for each individual receiver instance. If you have several receiver types connected to your site or several receivers of the same type, each separate receiver instance will have its own logs and version history.

You can access Virtual Receiver logs and version history directly from the relevant Virtual Receiver record.

All alarms from Virtual Receivers are also logged into the evalink talos event logs. The log files accessed from a Virtual Receiver Instance contain additional event entries that are not shown in evalink talos alarm logs.

For details about how to work with evalink talos alarm reports and event log reports, see section Working with Reports.

Virtual Receiver Logs Contents

When you click subject Receiver Logs button for a particular Virtual Receiver instance, you open a Virtual Receiver log dialog.

The figure below shows Virtual Receiver Logs dialog for a Virtual TNA Receiver:

By default, this dialog displays all receiver events during the last hour.

You can select a different time period in the top menu of the Virtual Receiver Logs dialog or set up a custom period by clicking Custom. For details, see section View Virtual Receiver Logs for a Specified Time Period below.

You can also filter logs by keyword. To do so, use the Filter by keywords field. Separate keywords by commas.

If you want to work with a log file outside evalink talos user interface, you can download the logs as a text file. To do so, click the download Download button at the bottom of the Virtual Receiver Logs dialog.

Keep in mind, that the downloaded file will contain the logs for the time period that you have configured. If you haven't done any configuration, by default, evalink talos includes events for the last hour into the downloaded log file.

The logs contain event entries from the Virtual Receiver instance as is, which means, they are not interpreted by evalink talos for better readability.
