Hi Aaron,

Assuming you refer to the caMonitor example code that comes with Base: this is an example for how to use the CA client library. In its sources it sets (line 27)
#define MAX_PV 1000  
which is most probably the limit you are experiencing.

For monitoring 5000 values, a command line client does not sound like a reasonable tool. If you can give some more details on your use case, there might be better ways to get it done.

Cheers,
~Ralph

Hello All,

I have a list of roughly 5000 PVs that I would like to monitor, but when I run the "./caMonitor" program with the full list it seems to only monitor less than half of the list.
Is there a limit to the number of PVs that can be monitored using the example "./caMonitor" program?

Thanks for any help that can be offered,
