This monitor and alert indicates that the Health Service has either failed to publish its public key to a management group in order to receive secure messages or it has received a secure message encrypted with the wrong public key.
Below is a summary of the default configuration of this monitor:
Red state: Transition to red state if the health service, within 6 hours, receives at least 10 occurrences of event that indicates the wrong key (7004), failure to publish key (7005), or expiring public key (7013)
Green state: Transition to green state automatically every 6 hours.
The critical state can indicate the following may be happening on the agent:
The Health Service received a secure message from a management group which was encrypted using the wrong public key.
The Health Service was unable to publish its public key to a management group and will be unable to receive secure messages until this key is published.
The key pair that the health service uses to receive secure messages from a management group is expiring.
No action required – the health service will try to automatically fix the problem by doing one of the following:
The health service will discard the secure message and re-publish the public key.
The health service will attempt to retry publishing the key.
The health service will be recycled and the key regenerated.
