Enterprise Library Instrumentation and microsoft exception handlingblock.

[archana]

hi all

i have used microsoft's exception handling block for publishing
exception to event viewer. but i am getting very different error when
exception occured on production. error source displayed as "Enterprise
Library Instrumentation" ad error discription varies but mainly like

"Failed to create instances of performance counter 'Cache Total
Turnover Rate' - The requested Performance Counter is not a custom
counter, it has to be initialized as ReadOnly.."

can anyone shed some light on it?

thanks in advnace.
