We do have such a capability, but it is not "official".
If you want to experiment with this do:
cd $RTDIR/smartview/conf
cp /opt/CPrt-R80/tmp/*8082*/webapp/config/cmdContextMenuActions.xml .
cp /opt/CPrt-R80/tmp/*8082*/webapp/config/contextMenuActions.xml .
Edit the contextMenuActions.xml file, and add new actions for log fields, using the same format. For example, to echo the application name, add:
<contextMenuAction>
<fieldsNames>appi_name</fieldsNames>
<actions>
<action>Echo</action>
</actions>
</contextMenuAction>
Edit cmdContextMenuActions.xml, and add the command to run for this action:
<cmdContextMenuAction>
<parentMenuName>Application Tools</parentMenuName>
<name>Echo</name>
<command><![CDATA[echo <parameter>]]></command>
</cmdContextMenuAction>
<parameter> will be replaced with the actual field value - Application Name in our case.
Restart SmartView:
$RTDIR/scripts/stopSmartView
$RTDIR/scripts/startSmartView
Share your experience with us.
If anything goes wrong, you can delete those files and restart SmartView again.
