| Msgs_queued
|
The number of queued message files in a particular channel's queue directories
|
Number
|
A consistent high value in this measure is an indication that messages are not being delivered, are being delayed in their delivery, or are coming in faster than the system can deliver them. This may be caused by a number of reasons such as a denial of service attack caused by a huge number of messages flooding your system, or the Job Controller not running.
Common symptoms of message queue problems are:
- Disk space usage grows
- User not receiving messages in a reasonable time
- Message queue sizes are abnormally high
|
| Msgs_held
|
The number of .HELD message files in a specific channel's queue directories |
Number
|
If the MTA detects that messages are bouncing between servers or channels, then delivery is halted and the messages are stored in a file with the suffix .HELD in IPLANET_MESSAGING_SERVER_ROOT_DIR/SERVER_INSTANCE_DIR/imta/queue/channel. Whenever you find a value for this measure you have to diagnose and clean up .HELD messages.
