"Holes" in Graphs

[Rudolf]

Hi all,

sometimes the displayed graphs have holes. the lines are interrupted. maybe I should increase the timeout? zabbix_server.log says:
"Timeout while receiving data from [myhost.mydomain]"
"The value is not stored in database".

what would be a good way to setup a trigger that checks for "holes" in the graphics?

If there is a timeout when retrieving values, is it because, or some combination of:

a) you are using a user parameter that takes too long to run?

b) the servers you are monitoring are too busy to respond?

c) your timeout value in your configuration is too small? ( look here and search for timeout: http://www.zabbix.com/manual/v1.1/config_files.php )

d) you are having intermittent network problems that are preventing the data from being sent to the server

e) something else?

Rather than try to detect the "holes", I suggest you find the root cause of why the data is not being returned.

As for detecting holes, a simple visual scan of the graphs does the trick.

Hi,

Indeed we use user parameters to check our web sites. 85 web sites, quite a lot. I modified an old script I found here in the cookbook forum (checkurl). Probably that's the problem. But I didn't find yet a better solution to check web sites. Connect to a web site, read it, if the words "yes I work fine" are found then return the time it took to connect. I should open a new thread for that.

Hi all,

I've the same problem in a production environment of 6 servers and 90 network devices.
The problem seems linked with the number of query that the server should take every minute.
I'm modified assigned StartSuckers=40 in zabbix_server.conf and the graphs are now correct.
