Evaluate Data Compression Performance

You can determine how effectively data compression is functioning at any given time by examining the Collector Detail Diagnostics on the Collectors section of the Dashboard, as shown in the Understanding the Interface topic.

The compression field at the top of the page shows the current effect of archive compression. If the value is zero, it indicates that compression is either ineffective or turned off. If it shows a value other than zero, it indicates that archive compression is operating and effective. The value itself indicates how well it is functioning. To increase the effect of data compression, increase the value of the archive compression deadband so that compression becomes more active. Values for this parameter should typically range from 0 to 9%.
