Question:
What is the Glutton MODE in VRM, what are the causes and how does it work?
Answer:
Enhanced glutton protection mode is a new feature in VRM versions e.g. VRM 3.71 and newer.
The prevention of a glutton (German: Vielfraß) defines and prevents a camera or multi-channel encoder from mounting and consuming a large number of blocks in a very short time.
If a device is placed in glutton mode, VRM performs the following operations:
- All blocks except the actual mounted and recording block are removed from the camera span list.
- If a device is in glutton mode, it gets only 6* number of configured cameras blocks per hour.
- The device is monitored and when block consumption returns to normal, it is removed from Glutton Mode.
Possible messages when a camera is in Glutton mode are as follows:
- This device has an abnormal high storage consumption. To protect other recordings, storage allocation is reduced. This may result in recording gaps for this device.
- Device runs out of storage and might stop recording.
- This device had an abnormal high storage consumption and is now set back to regular mode.
Glutton Mode possible causes:
- BVMS Profiles: Normal-Good-Excellent used on any Current CPP.
- Corrupts the Camera Configuration, VRM will place camera into Limited span mode (6 spans per hour max).
- Bad Time Server: If Time Server jumps more than 2 seconds (Forward or Backwards) frequently.
- Causes Camera to prematurely release blocks and take new ones.
- Network Issues: Wireless, bad cables, bad switch ports, port 3260 blockage issues, network disconnections, etc.
