Archive Statistics

Displayed Charts

The charts of the Archive Statistics dialog provide a quick overview of the current MxFFS archive status (see also Storage on External File Server / Flash Device).

Displayed Charts

Parameter	Description
Transfer Statistics
Bandwidth Histogram: Connection Speed	Connection speed as measured during individual data transfers. Due to buffering, this chart can show values that are higher than the actual available network bandwidth.
Bandwidth Distribution	Distribution of the bandwidth that is available for transfers during the day (i.e., the last 24 hours).
Archiving History
Maximum Queue Fill Level	Distribution of the MxFFS data blocks waiting for transfer during the day (i.e., the last 24 hours). Notes Permanently high values in this chart indicate that the network is running at capacity. You should take measures to reduce the network load (more powerful hardware, segmenting the network into smaller parts, etc.). Peaks in this chart indicate that the camera was unable to reach the server.
Enqueued 4MB blocks	Number of MxFFS data blocks waiting for transfer during the day (i.e., the last 24 hours). Notes Permanently high values in this chart indicate that the network is running at capacity. You should take measures to reduce the network load (more powerful hardware, segmenting the network into smaller parts, etc.). Peaks in this chart indicate that the camera was unable to reach the server.
Transferred 4MB blocks	Number of MxFFS data blocks transfered during the day (i.e., the last 24 hours). Note The number of blocks in this chart is an indicator for the volume of transfered data (number x 4MB) as well as the attained data rate.
Lost 4MB blocks	Number of lost MxFFS data blocks during the day (i.e., the last 24 hours).
Archiving Reliability
Archive Connection Outages	Pattern of the detected archive connection failures in the course of the day since resetting the archive statistics. Note Frequent or evenly distributed connection failures indicate that the network is running at capacity. You should take measures to reduce the network load (more powerful hardware, segmenting the network into smaller parts, etc.).
Archive Verification Errors	Pattern of the errors detected when verifying the transferred archive data in the course of the day since resetting the archive statistics.
Block Retransmissions	Pattern of retransmissions of MxFFS data blocks in the course of the day since resetting the archive statistics.
Buffered Transfers
Direct Transfers into Archive	Percentage of MxFFS blocks written directly into the archive, i.e., there was no need to buffer these blocks on the SD card. Notes This value should be somewhere short of 100 % (it is impossible to reach 100 %; see note in section Target Switches). Values that are considerably lower than 100 % in this chart indicate that the network is running at capacity. You should take measures to reduce the network load (more powerful hardware, segmenting the network into smaller parts, etc.).
Target Switches	Number of instances in which the camera had to switch between direct archive storage and buffering on the SD card. Note Note that the camera switches back and forth between direct archive storage and buffering on the SD card a couple of times per hour for administrative purposes.
Internal Storage Statistics
Internal Transfer Bandwidth Histogram	Allows assessing the speed with which the recorder stores blocks in the internal buffers.
Internally Transferred 4MB Blocks	Number of blocks stored in the course of the day (or since rebooting the camera).

Note

If a chart shows time-of-day values, the current interval is highlighted in yellow.
