Host status never change, even if the host is down! help

[eric]

hi, everyone:

I monitored a few hosts with cacti, but now i find when one of hosts is down, the status of the host is still up.

I go through the whole forum, but I can't find solution.

I have tried the method introduced by TheWitness at http://forums.cacti.net/about9730-0-asc-0.html. but it doesn't work.

I tried to use:
snmp and ping
snmp
ping(udp/icmp)

they all don't work. the host down is still up...

I checked the database during i am testing. the stuts is always 3

mysql> select status, status_event_count, status_fail_date from host where id=29;
+--------+--------------------+---------------------+
| status | status_event_count | status_fail_date |
+--------+--------------------+---------------------+
| 3 | 0 | 2006-01-21 01:38:00 |
+--------+--------------------+---------------------+
1 row in set (0.00 sec)

what's the wrong?

TheWitness, can you give me some suggestion?


I used the monitor plugin, if it cause the problem?

thx!

1) You monitoring the host with SNMP?

2) Post the portion of a DEBUG log, where cacti tests to see if the device is up.

3) What version of everything are you using?
