Do you have any other hosts, servers, etc. being monitored? Are they collecting any data?

Have you checked the server log file to see if it shows any errors? You might also want to try changing the debug level to 4 on the server and see if that gives you more information if the default level doesn't tell you anything.

I'm not sure which logs I should be looking at. Should I go into the syslog? Is there a specific log file for the zabbix server that gives me this information?

In your server.conf file do you have a line specifying a log file?

Code:

logfile=/tmp/zabbix_server.log

? I think the default if this line does not exist is to dump the log information to syslog.

ok, I found it in my /tmp/zabbix_server.log file.

However, I now see data for those checks. What's strange is that I had the server running, put in the items that I wanted to monitor, then shut the server off and restarted it. I still was not seeing results after doing this.

I came in this morning, and the server was not running. I started it back up, and now I have the monitoring I was looking for at the end of last week.

So, here's another question: Why would the zabbix server just shutdown? The log file showed:

014978:20060823:205320 Timeout while receiving data from [App1]
014978:20060823:205320 Getting value of [net.tcp.port[app1, 8080]] from host [App1] failed

014970:20060823:205339 ZABBIX server is down.

However, I couldn't get the long line where it shows the Query, and when I went to get it, the log file was cleared. I'll look around for a way to make the log file stick around or roll over or something.

If anyone has any ideas on why this install is acting flaky, please let me know.

Thanks

I had the same problem for a while, I ended up putting this script together that monitored if the system crashed and sends an email to me as well as restarting the server and saving a copy of the last log file in a seperate file so it's not overwritten.. here is the script. I took it from someone else that posted it and made a few minor modifications..

Code:

#!/bin/bash

##################################################  ###############################
#																			   #
# Please look at first how many processes zabbix_server and zabbix_agentd have. #
# Then change the entries in the lines.										 #
# Change the email address!													 #
#		created by Krusty													  #
#																			   #
##################################################  ###############################

date=`date`
prozessserver=`ps -ef | grep zabbix_server | grep -v grep | grep -v tail | wc -l`
serverpid="/var/tmp/zabbix_server.pid"
#echo "Debug server: $prozessserver"

if [ $prozessserver -lt 4 ];
then
		echo "There is no zabbix_server process running. I will start this process now! $date"
		if [ -f $serverpid ]
		then
				echo "File $serverpid exists. I will remove this file now!"
				rm $serverpid
		fi

	echo "$date " >> /tmp/zabbix_checkstatus.log
	ps -A | grep zabbix >> /tmp/zabbix_checkstatus.log

	cp /tmp/zabbix_server.log /tmp/zabbix_server.log.crash
	cp /tmp/zabbix_server.log.old /tmp/zabbix_server.log.old.crash
		/usr/local/bin/zabbix_server

	   echo "At $date the zabbix_server process was not running. But the server will be started immediately." | mail -s "Zabbix Server crashed at $date" [email protected]
fi

prozessagentd=`ps -ef | grep zabbix_agentd | grep -v grep | grep -v tail | wc -l`
agentdpid="/var/tmp/zabbix_agentd.pid"
#echo "Debug agentd: $prozessagentd"
if [ $prozessagentd -lt 2 ];
then
		echo "There is no zabbix_agentd process running. I will start this process now! $date"
		if [ -f $agentdpid ]
		then
				echo "File $agentpid exists. I will remove this file know!"
				rm $agentdpid
		fi
		/usr/local/bin/zabbix_agentd

	echo "At $date the zabbix_agentd process was not running. But the agentd will be started immediately." | mail -s "Zabbix Agentd crashed at $date" [email protected]
fi

exit 0

Now as far as what my problem was, it turned out I had some corruption in my databases... and that was crashing my zabbix server... I had similar lines in my server log.. http://zabbix.com/forum/showthread.php?t=3163

ok, I'll check into the database possibly having errors tomorrow. It's entirely possible that we could have some. Thanks for all the help so far.
