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.
