------------------------------------
Github user SolidWallOfCode commented on the pull request:
https://github.com/apache/trafficserver/pull/343#issuecomment-160667524
I have updated the PR with several changes.
* "Alert" is now "Message"
* Messaging is a privileged operation.
* Messages have a tag and payload (data). The former is a null terminated
string and the latter is a slab of bytes.
* traffic_ctl requires both tag and data to be null terminated strings
because they are both command line arguments.
I haven't had a chance to work on example uses yet, although I have made
progress in designing them.

> Add another event to the lifecycle hook, ALERT. This will be sent only from
> an external API, e.g. {{traffic_ctl}}. Any plugin that wants to be alertable
> from the command line can attach to this hook and watch for the event
> {{TS_EVENT_LIFECYCLE_ALERT}}. The data for the event wil be a string that is
> provided by the external agent.
