Metrics Storage

The metrics are primarily stored in the vovserver memory. You can choose how much RAM is to be used for the metrics using the parameter metrics.maxmem, which is a value in MB.

When the total RAM used by the metrics exceeds this value, metrics will be reduced by a combination of methods, chosen automatically by vovserver:
  • Cropping of old data
  • Reduction of accuracy of old data
  • Cropping metrics that are not recently accessed

The metrics are saved from time to time to files in the server working directory, precisely under the directory PROJECTNAME.swd/data/metrics. One or more files are used for each metric. The name of the files is the name of the metric itself, possibly extended with a timestamp.
