Overview
In Monitoring → Problems you can see what problems you currently have. Problems are those triggers that are in the "Problem" state.
| Column | Description |
|---|---|
| Time | Problem start time is displayed. |
| Severity | Problem severity is displayed. Problem severity is based on the severity of the underlying problem trigger. Colour of the trigger severity is used as cell background. For resolved problems, green background is used. |
| Recovery time | Problem resolution time is displayed. |
| Status | Problem status is displayed: Problem - unresolved problem Resolved - recently resolved problem. You can hide recently resolved problems using the filter. New and recently resolved problems blink for 30 minutes. Resolved problems are displayed for 30 minutes in total. Both of these values are configurable in Administration → General → Trigger displaying options. |
| Info | An green information icon is displayed if a problem is closed by global correlation or manually by acknowledgement. Rolling a mouse over the icon will display more details: |
| Host | Problem host is displayed. |
| Problem | Problem name is displayed. Problem name is based on the name of the underlying problem trigger. |
| Duration | Problem duration is displayed. See also: negative problem duration |
| Ack | The acknowledgement status of the problem is displayed: Yes - green text indicating that the problem is acknowledged. A problem is considered to be acknowledged if all events for it are acknowledged. No - a red link indicating unacknowledged events. If you click on the link you will be taken to a bulk acknowledgement screen where all problems for this trigger can be acknowledged at once. This column is displayed if problem acknowledgement is activated in Administration → General. |

Negative problem duration
It is actually possible in some common situations to have negative problem duration i.e. when the problem resolution time is earlier than problem creation time, e. g.:
- If some host is monitored by proxy and a network error happens, leading to no data received from the proxy for a while, the item.nodata() trigger will be fired by the server. When the connection is restored, the server will receive item data from the proxy having a time from the past. Then, the item.nodata() problem will be resolved and it will have a negative problem duration;
- When item data that resolve the problem event are sent by Zabbix sender and contain a timestamp earlier than the problem creation time, a negative problem duration will also be displayed.
Using filter
You can use the filter to display only the problems you are interested in. The filter is located above the table.
