Dear Community,

I am creating application to monitor disk response time at VM level using ioping. 

But every time i run the poller with debugger, i’ve got no error but my application always been deleted by the system because its lastpolled is 0. i’ve try to follow the documentation, but its seems like i can’t get solution. 

Do you guys have any solution for this or you have the same problem?

here's the unix agent output :

<<<app-ioping>>>

reqps:2110

tfspeed:34565401

minreqtime:329

avgreqtime:474

maxreqtime:591

here's the pollling debug result :
