An alarm is an event generated by a Netreo monitoring check when it enters a critical state. There is not much to know about alarms other than that they are used to manage internal activity within Netreo while a check is in that state.
Alarms become associated with incidents and may be viewed in the Incident View dashboard for any particular incident.
Alarms should not be confused with alerts. They are independent concepts. In general, think of an alert as being the typical result of an alarm. Although it is possible for an alarm to exist without causing an alert.
How Alarms Work
Each type of monitoring check has its own criteria for when it will generate an alarm. See the individual entries for each check type for more information.
When a monitoring check generates an alarm, that alarm contains basic information about the problem, such as the device and specific check involved. Once an alarm is generated, it immediately attempts to open a new incident to house it and its information. (If Netreo’s incident management system determines that an alarm is being caused by an already open incident, that alarm is bundled into the open incident rather than being allowed to open a redundant new incident of its own.)
While an alarm is occurring, the monitoring check that caused it continues to perform its monitoring duties. If the results of the check bring its status back down below critical, the resulting alarm is cleared and its associated incident is notified. When all of the alarms associated with an incident have cleared, and a specific period of time has passed (typically five minutes), that incident automatically closes itself and records the event in the audit log. (It is important to note that an incident cannot be closed until all of the alarms that it contains have cleared.)
Alarms cannot be directly interacted with in Netreo, but they may be viewed in the Incident View dashboard of the incident with which they are associated.
View the alarms for an incident
- Locate the incident for which you wish to view the alarms. Two ways to do this are:
- Go to the main menu and selecting Quick Views > Active Incidents. Locate the incident in the list and select it.
- Enter the incident ID into the search box of the main menu bar, then select it’s entry from the search results.
- Any current alarms associated with the incident are displayed in the Incident Detail panel of the Incident View dashboard.
