Nagios Support Forum

Hello and good morning. I'd like to apologize you for my bad english. I am not sure how nagios forum works because I can't post my problem in a new thread and this seem be similar to my own problem. I'm going to try to explain it.
I'd like to send a executive summary to my email acount but the file is generated whit O kb and acrobat, of course, can't read it.
The messages in file logs said:
HHTP request sent, awaiting response ...sh:/usr/bin/wkhtmltopdf: No such file or directory....
Undefined variable: fullbody in /usr/local/nagiosxi/reports/execsummary.php on line 360
200 ok....


If I send miself another kind of reports, as availability or state history all work fine.

Could you help me?
Thank you so much.

What version of Nagios XI are you using? Does this happen with other reports? Is there valid data in the executive report for the timeperiod you selected?

I'm using Nagios XI (2012 R2.2) version. Availability, state history, top alerts, alert histogram and notifications are working fine.
Besides, the information from executive summary on the screem seem be correct.

If you still keep the original install directory in /tmp, do the following:

Open the wkhtml install script in a text editor:
Then change this line: to this: Then run: Let us know if this fixes your issue.

Morning!!
Execsummary report is already working now although error_log file shows next message:

PHP Notice: Undefinied variable: varr in usr/local/nagiosxi/html/includes/components/latestalerts/latestalerts.inc.php on line 282, referer: http://nagiosxi/nagiosxi/reports/execsummary.php?

I don't know if it's important or not because in pdf file is show the same information than nagiosxi screen.
We are having another problem... Event log report only works from legacy mode.
Even log available reports screen is emply while even log legacy reports screen is full of events.
Could you help me whit this issue too?

Thank you so much!!

The php notice will probably not cause this issue. Lets check the logs.
Do a running tail on the apache error log. While the tail is running, try browsing to the "event log" in XI. Copy the output of the tail and post it in code wraps in your next post. Kill the tail with crtl-c after you have copied the errors.

Hi, morning!
Error_log file showed...
[Tue Aug 27 13:06:43 2013] [info] [client x.x.x.x] (32)Broken pipe: core_output_filter: writing data to the network
but surfing by the internet I have been able to resolve the problem. I have added next line in /etc/httpd/conf/httpd.conf

EnableSendfile Off

And now, httpd service seem to work ok.

Unfortunately, the problem whit event log reports is going and httpd/error_log file don't show any problem.
This is the result of tail -f /var/log/httpd/error_log after restart httpd service and browser to the "event log"

Do you get an "empty" Event Log report when you change the "Period" from the "Last 24 Hours" to a something else (let's say "This Month")?

Yes, the result is the same whatever period time I choose

Are you viewing XI via ssl? If so you need to try tailing the /var/log/httpd/ssl_error log file.
