If a performance instance uses another collection interval, it corresponds
to a number of collection units calculated with the formula: 5
minutes/instance collection interval in minutes. For example, if the
collection interval is 10 minutes for all performance instances, to collect
performance data including CPU, memory, interface send and receive
rates, unreachability rate, and response time on a device that contains
one CPU, one memory bar, and 10 interfaces, the total collection units of
the device are: (1+1+10×2+1+1)×5/10=12.

NOTE:
•
Make sure you have stopped IMC before you change the Java Heap
size.
• The Java Heap size for a 32 bit-operating system cannot exceed 1 GB.
If a larger Java Heap size is required, use a 64-bit operating system.
How can I collect the IMC logs for technical support?
Use the log collection tool provided by IMC:
• On Windows, the tool is located in the \deploy\logfiles.bat directory of
the IMC installation path.
