Availability of the host/application

[kelbel]

Hello, I have the following scenario:

- Zabbix geographically dispersed clients
- Zabbix_agentd queries using Active Mode
- Monitored application uses flags to disclose their status
* 0 - Disabled
* 1 - Running
* 2 - Problem


I'm getting all the data correctly, even have a trigger that tells me if the application is with status 0 or 2, but I have two questions:

1) The status of the host is always "Unknown", why? I would like to stay as follows:
- Status = 1 -> "Available"
- Status = 0 or 2 -> "Unavailable"

2) Is there a way to calculate the downtime of the application? For example, it was stored as long as I'm getting the status of 0 or 2 and then calculate the sum of it, within 1 month.
This would permit "see" that the application was out 1d 2h in the last month, in the case.


Thanks in advance.

Have you tried to telnet the agent and query the item to verify if the output is correct?

I don't extensively use active checks, but I think the hostname in zabbix_agentd.conf and the host name on the server (not the DNS name) must match exactly.
