Best Practices for Working with Data Collectors

Here are some best practices that enable the collectors collect and store the most accurate data:

• Synchronize the Windows clock for the following computers:
  • Source Data Archiver of a Server-to-Server Collector
  • Computer on which the Data Collector is running
  • Destination Data Archiver
• Turn on the Data Recovery Mode option for Historical Collectors such as Server-to-Server and Calculation Collectors. This ensures that most gaps in data collection due to the unavailability of source Archiver or in the case of collector not running are automatically filled in the next time the collector runs.
• If you are using polled collection with Calculation or Server-to-Server Collector, ensure that you have at least one uncompressed polled tag so that the polled data is frequently sent to the destination Archiver. This ensures that the bad data marker sent when a collector shuts down has an accurate time stamp that reflects the time of shutdown of the collector.
