eG Monitoring
 

Measures reported by XchgVirusScanTest

Messages received on an Exchange server and the attachments they contain are often scanned by anti-virus software prior to acceptance and delivery. This test monitors the performance of the mail scanning and virus processing sub system. Information about bottlenecks in the Virus scanning subsystem, or situations when excessive viruses are being delivered via mail messages or attachments can be detected by this test.

Measurement Description Measurement Unit Interpretation
Scan_queue_length The number of requests that are currently queued for virus scanning Number An excessive value for this metric could result in slowdown of mail delivery
Files_cleaned The percentage of all files scanned during the last measurement period that required to be cleaned Percent  
Files_quarantined The percentage of all files scanned during the last measurement period that required to be quarantined Percent  
Messages_cleaned The percentage of messages scanned during the last measurement period that required to be cleaned Percent  
Messages_quarantined The percentage of all messages scanned during the last measurement period that required to be quarantined Percent  
File_clean_rate The rate at which separate files were cleaned by virus scanner during the last measurement period Files/Sec  
File_scan_rate The rate at which separate files are processed by virus scanner during the last measurement period Files/Sec A very low scan rate could result in over-crowded scan queues, which would eventually slowdown mail delivery.
File_quarantine_rate The rate at which separate files were marked to be quarantined by virus scanner during the last measurement period Files/Sec  
Msgs_clean_rate The rate at which top-level messages were cleaned by virus scanner during the last measurement period Msgs/Sec  
Msgs_process_rate The rate at which top-level messages were processed by virus scanner during the last measurement period Msgs/Sec Ideally, messages should be quickly processed by the virus scanner. Any dip in this rate is a cause for concern, as it would lengthen scan queues and ultimately delay mail delivery.
Msgs_quarantine_rate The rate at which top-level messages were put into quarantine by virus scanner during the last measurement period Msgs/Sec
