Nagios Core doen't show all services on page

Hello, I have started using Nagios Core for monitorize Windows Servers. After a lot of headaches and lot of research, I did it work. I use WMI to do it. This is what I use:
S.O: Debian 8.2
Nagios: Core 3.5.1 (from Debian Repository)
Apache: 2.4 (from Debian Repository)
wmic: 1.3.14 (from source)
check_wmi_plus: 1.54
pnp4nagios: 0.6.25 (from source)
The problem I have happens when I want to see all the services of all hosts, I don't see all the services at first (despite having less than 100 services). After a couple off auto-refresh, all the services are seen. I assume this is a problem or a bad configuration of Apache but I don't know where to start. Greetings.

What do you see logged in the apache error logs:
Code: Select all
tail /var/log/httpd/error_log -n 100
Are you able to show a screenshot when it is not showing all the services. You might have a filter on and it's not showing pending services.

I did some research and I found there is problems with unprintable characters in "service_description" what causes the problem I got. I removed those characters but the problem is still there. Thanks a lot for your answer.

Are any of those unprintable characters in the service status information column?

Yes they are, it is what I was not having in mind. I kept searching and Nagios does not support it. The thing is that all OS are installed in spanish so the results of the queries have unprintable characters. Is there any way to change this in Nagios?
I am thinking in a workaround with check_wmi_plugin, to replace or remove those characters. Thanks for your answer.

We have someone who works with Nagios Core in the Spanish language,
@lcontreras, I'm going to reach out to him to see if he has come across this problem.

Meanwhile i have found a workaround. It consist on use of "sed" command. The problem was in the output of the services so in the "commands.cfg" file added to the "command_line".
ie:
Code: Select all
command_line ($USER6$/check_wmi_plus.pl -H $HOSTADDRESS$ -m checkservice -u $USER8$ -p $USER9$ -a '$ARG1$' -o '$ARG2$' $ARG3$ $ARG4$ $ARG5$ | sed -f $USER6$/replaces.sed)
I created a file named replaces.sed which contains the characters to replace. ie:
Code: Select all
s/\ß/a/g
s/\Ú/e/g
s/\Ý/i/g
s/\¾/o/g
s/\·/u/g
And now it works as it should do.
