client machine problems ( connectivity)

[nightwish]

Hi All

I'am using zabbix 1.8.3 in a centOS.

I have 30 machines in my zabbix server. Althought few of then seems to have a connection problem.

I am prety shure that there are no LAN problems.


This is the problem that I'am getting. From time to time the zabbix server cannot communicate whith agent and refresh all itens.

In the events of items from that client machine I get:

OK Information 31m 16s No -

2011.Jan.05 17:36:35 /etc/passwd has been changed on server xxxxx UNKNOWN Information 26s No -

2011.Jan.05 17:16:58 /etc/passwd has been changed on server xxxxx OK Information 51m 19s No -

2011.Jan.05 17:16:36 /etc/passwd has been changed on server xxxxx UNKNOWN Information 22s No -

2011.Jan.05 16:01:57 /etc/passwd has been changed on server xxxxx OK Information 2h 6m 20s No -

2011.Jan.05 16:01:40 /etc/passwd has been changed on server xxxxx UNKNOWN Information 17s No -

2011.Jan.05 15:06:57 /etc/passwd has been changed on server xxxxx OK Information 3h 1m 20s No -

2011.Jan.05 15:06:39 /etc/passwd has been changed on server xxxxx UNKNOWN Information 18s No -

2011.Jan.05 14:41:57 /etc/passwd has been changed on server xxxxx OK


Any idea why this may happen.

Thanks in advanced.

post item update interval & trigger expression for that item.

could it be that your zabbix server or database is overloaded ?

Hi richlv

Thanks by reply.


This happens in all itens/triggers. In a few machines.

It seems that zabbix cannot contact the agent by a few seconds.


All the itens start to bliking with the updated status.

This is in dead very strang.

Any ideas ??
