Operating
Overview
The Executive Report in MetaDefender Core provides statistical data on file scanning performance and processing metrics. This document explains the key terms, metrics, and values displayed in the report to help you better understand your MetaDefender Core deployment's performance.
Processing Stages
| Definition | Explanations |
|---|---|
| Hashing | The process of calculating cryptographic hash values (such as MD5, SHA-1, SHA-256) of the scanned files. |
| In-Queue | The time a file spends waiting in the processing queue before active scanning begins. |
| Archive Extraction | The process of unpacking and analyzing compressed or archived files (such as ZIP, RAR, 7z, etc.). |
| Waiting (including reasons for waiting) | The waiting time when processing by Metascan™™™ engines |
| Nested Files | The waiting time for completely processing all nested files of an archive file |
Duration Values
| Definition | Explanations |
|---|---|
| Average | The arithmetic mean of processing times for all files during the reporting period. |
| Max | The longest time any single file spent in a particular processing stage during the reporting period. |
| Min | The shortest time any file spent in a particular processing stage during the reporting period. |
How to calculate
Average = Total Time Spent in Stage ÷ Number of Files Processed
Example:
File A with Hashing time = 5
File B with Hashing time = 10
File A with Hashing time = 12
- Average Hashing = (5 + 10 + 12) / 3 = 9
- Max Hashing = 12
- Min Hashing = 5
