Meaning
Trouble
A severe condition has occurred. These include loss of network connectivity, loss of HTTP access, and full disk conditions (by default, over 95% full), since these can result in a system hang.
Generally, any red condition results in the administrator being notified. Any ERROR message in the message file also causes a notification since this may signal a fault.
If a severe situation is occurring that is not being noticed by Big Brother, use the acknowledgement HTML page to notify the administrator manually.
No report
No report from this client for this test has been received in the last 30 minutes (by default; you can change the time threshold). This may be the result of a heavily loaded system, or could indicate a more serious loss of communication within the Big Brother system itself, either at the client or the Big Brother server. For example, the server may not be accepting connections.
Attention
The reporting system has reached a threshold you should know about. These include HTTP server errors, disks almost full (90-94% by default), important processes not running, and WARNING messages in the messages file.
OK
Everything is fine. A completely green screen represents a seldom achieved state of administrative bliss.
Unavailable
The associated test has been turned off or does not apply. A common example is connectivity on disconnected dialup lines
Offline
Notification for this test has been disabled. Generally used when performing maintenance
Acknowledged
The notification associated with this event has been acknowledged by one of the recipients
