On the first day of each month, the archive process removes all performance metrics from the Uptime Infrastructure Monitor DataStore that are older than the specified number of months in the Archive Policy.
For example, if Overall CPU / Memory Statistics is set to six months, on the first of the month when the archiving process runs, all CPU and memory metrics older than six months are removed from the Uptime Infrastructure Monitor DataStore.
If archived data is required for graphing or reporting purposes, you can import it back into Uptime Infrastructure Monitor by using the restorearchive tool, which can be found in the Uptime Infrastructure Monitor scripts directory.
Note
Archiving large sets of performance data may time out. If this occurs, contact [email protected] to discuss alternate methods for removing unnecessary historical performance metrics.
