View Full Version : get_value_agent is not called for all hosts in 1.1.1 ?
Hello all,
I am experiencing that zabbix 1.1.1 does not get values for all host, only for some of them. I have still old data in some servers, even if status of server and item is "active". I cannot find some glue why some servers work and some not. I read in this forum that there are more people like me. Does somebody has some hint ? It is very bad, our monitoring is entirely broken :( I will downgrade to 1.1 probably just now :(
When I do traffic dump, I do not see any request to agent ports for broken servers, but I can see traffic to good servers. Simple items, icmp, snmp works.
Any suggestions??
I do not remember any changes in 1.1.1 that might potentially affect this functionality. Are you saying that some hosts are not monitored at all?
I see only host status 0, icmp replies ok and agent values are old. When I look into config, I see that all servers are active and monitored. But to some of them, zabbix_server never sends any communication to port 10050 (I tried tcpdump).
Even items are enabled and active.
It probably does not seem to be problem with zabbix 1.1.1, I downgraded to zabbix 1.1 and everything is same :( Maybe we have some problem in db.. ? But why frontend says everything is ok but zabbix_server does not checke that hosts?
Thank you for any advice..
Anything in ZABBIX server log file? Perhaps you changed system time to past?
This is in server.log. I tried to increase debug level but no success, I did not any relevent information about missing hosts and get_value_agent. Only checks to working servers were found.
Please what it means: started [Poller. SNMP:ON] ? It means poller for SNMP, not for agent checks? So am I missing some process?

Hi all,
I just solved my problem. Problem was that in zabbix_server.conf, there was option StartSuckers which changed to StartPollers. And only 5 pollers are started by default and it was too little to check all servers.
I know it is probably my problem, because I did not read documentation.. But..
My BIG SUGGESTION is , please , Alex, make logging more verbose.. When I changed loglevel to 2, I see only infos about processes start and unreachable hosts. When I increase level, I see many sql statements, but did not see real problem there..
I think it should be good to write at least config parameters at start to logfile (StartPollers, StartTrappers, ..) . Next, there should be some logic to write that tehere is too small number of pollers or trappers (when all are busy). It is enaught to write "warning - all pollers threads busy".
It was very ard to find source of my problem.. And took too much time.
Thanx,
Lukas
