Monitoring Interface
Figure 1: Monitoring Interface Overview
The Monitoring interface provides the following key functions:
Real-Time Monitoring - Offers a comprehensive real-time view of collected data with flexible filtering, sorting, and search mechanisms to target specific information. Multiple display formats are available to accommodate different operational needs.
Interactive Control - Provides users with the capability to perform real-time actions on the supervision system through predefined operations, including:
- Re-scheduling checks
- Programming downtime periods for resources
- Acknowledging incidents and alerts
Host Monitoring
The host monitoring interface can be used to view the evolution of the supervision of its information system in real time.
Figure 2: Host Resource Status View
Status
Statuses are indicators for the hosts or the services. Each status has a precise meaning for the object. To each status corresponds a code generated by the monitoring plugin according to thresholds defined by the user/s
Host Status
The table below summarizes all the possible statuses for a host.
| Status | Description |
|---|---|
| UP | The host is available and reachable |
| DOWN | The host is unavailable |
| UNREACHABLE | The host is unreachable |
Table 1: Host Status Indicators
Service Status
The table below summarizes all the possible statuses for a service.
| Status | Description |
|---|---|
| OK | The service presents no problem |
| WARNING | The service has reached the warning threshold |
| CRITICAL | The service has reached the critical threshold |
| UNKNOWN | The status of the service cannot be checked (e.g.: SNMP agent down, etc.) |
Table 2: Service Status Indicators
Advanced Statuses
In addition to the standard statuses, new statuses can be used to add additional information.
- The PENDING status is a status displayed for a service or a host freshly configured, but which has not yet been checked by the scheduler.
- The UNREACHABLE status is a status indicating that the host (parental relationship) is situated downstream of a host with a DOWN status.
- The FLAPPING status indicates that the status change percentage of the object is very high. This percentage is obtained from calculations performed by the network monitoring engine.
- The ACKNOWLEDGED status is a status indicating that the incident of the service or the host has been taken into account by a user.
- The DOWNTIME status is a status indicating that the incident of the service or the host occurred during a downtime period.
Soft And Hard States
A host or a service can have two states: SOFT: Signifies that an incident has just been detected and that it has to be confirmed. HARD: Signifies that the status of the incident is confirmed. Once the status is confirmed, the notification process is engaged (sending of an email, SMS, etc.).
Status Confirmation
An incident (Not-OK status) is confirmed as of the moment when the number of validation attempts has reached its end. The configuration of an object (host or service) requires a regular check interval, a number of attempts to confirm a Not-OK status and an irregular check interval. As soon as the first incident is detected, the state is “SOFT” until its confirmation into “HARD”, triggering the notification process based on the number of validation attempts defined.
Generic Actions
The following icons are available for controlling the monitoring interface:
| Icon | Action | Description |
|---|---|---|
 | Refresh | Serves to refresh the results manually. |
 | Pause | Serves to put the automatic data refreshment into pause. |
 | Restart | Serves to restart automatic data refreshment. |
