Guidelines to setting up probes polled via history operation table

1. These probes must have lives-of-history set to 1 or more (usually, 1 is enough).

2. These probes must have buckets-of-history-kept set to 1 or more (for a probe running every 30 second, on a device being polled every 5 minutes, this value should be greater than 10 to avoid losing any data).

3. These probes must have filter-for-history set to all (otherwise, no data will appear in the History table).
