Disk I/O bandwidth monitoring

[sccuser]

I'm trying to monitoring Disk I/O bandwidth and Net traffic bandwidth with below Item settings





What im expecting is to get alarm trigger if within 60s

Disk I/O bandwidth < 0.6 Mbps
Net traffic bandwidth < 0.6 Mbps

I tried following but it did not work

{Templates_cameraerf_counter[\PhysicalDisk(_Total)\Disk Write Bytes/sec].min(60)}<0.6M
{Templates_camera:net.if.in[{IPADDRESS},bytes].min(60)}<0.6M

Pls refer the below graph.



Any suggestions?
