| Which tool are you talking about? |

There is no such thing as a monitoring tool that can monitor everything in an infrastructure. It is very likely different tools are used by different groups of specialists. A network specialist might be using Concord eHealth or HP Openview Network Node Manager (NNM). A UNIX specialist might be working with HP Openview Operations (OVO) or Concord eHealth. A Windows specialist might be working with MOM2005 or OVO. Knowing the specialist helps in guessing which tool a person is using. But if you don’t know the person, how do you tell which tool he is using (without a glance at the computer screen of course)? Elementary, my dear Watson, you listen to him. The first clue is the word used for a message that appears in the tool to indicate something is wrong or some threshold has been crossed. In HP Openview Network Node Manager these messages are called alarms and they appear in the Alarm Browser. However, a NNM administrator might be talking about events, which are the source of the alarms.
Unfortunately, other tools also use alarms and events. The word alarms is also used in Concord eHealth, where they appear in the GUIs called Live Exceptions or Live Status. The word event is very common to MOM, where events are sent through from the Windows eventlog. Some of the events, depending on their importance, generate an alert. (Every alert comes from an event, but not all events generate an alert). In HP Openview Operations, the message is called a message and it can be seen in the Message Browser
The words used for interacting with these messages are your second clue. What you do with a message as an operator or a system administrator for example, depends on the tool. And even when the same words are used, they might mean a completely different thing. In HPOV NNM you can acknowledge and delete alarms. Acknowledge means you have seen the alarm; it stays in the browser and has a checkmark in front of it. Deleted alarms are gone forever.
In Concord, sending a message to the history is called clearing, but acknowledging is like in NNM, putting a checkmark in front of a message to show you have seen the message.
In Openview Operations messages can be owned. They change colour and stay in the active message browser. No one else but you can acknowledge the message, which means sending it to the history browser. In MOM it works a bit differently: you have to change the status of a message, from New (the default status of new alerts) to Acknowledged, when someone has seen the message, and Resolved when you want to send the message to the history browser. Of course, the word acknowledge is used in the same way as in NNM and in Concord. By the way, these statuses may have been replaced by the MOM administrator for other statuses names, since they can be configured in MOM.
