             Summary: Fix traffic_shell broken by TS-1740
                 Key: TS-2174
                 URL: https://issues.apache.org/jira/browse/TS-2174
             Project: Traffic Server
          Issue Type: Bug
          Components: Stats
            Reporter: Yunkai Zhang


I'm sorry for too late to fix this bug.

Here is an example about the broken of traffic_shell(reported by 
Esmq<[email protected]> ):
{code}
echo 'show:proxy-stats' | sudo /usr/local/trafficserver/bin/traffic_shell
Successfully Initialized MgmtAPI in 
/usr/local/trafficserver-4.0.1/var/trafficserver

Since I nearly didn't use traffic_shell, and traffic_line works well for me, I 
didn't notice this bug.

The root cause of this issue is that traffic_shell use RecFloat type to read 
most stats variables, though these variables are no longer RecFloat type after 
applied TS-1740, as a result bad conversion occurred.

We should make traffic_shell works as traffic_line, use the correct conversion 
to read stats variables.
