PNP Graph Template issue

[Eurocash]

Hi,

I have issue with check_iftraffic64 plugin and PNP Graph template downloaded from here:
https://exchange.nagios.org/directory/P ... 64/details

Our nagios version: Nagios XI 5.4.13

Check command:
check_band_usage3_copy_1
/usr/local/nagios/libexec/check_iftraffic64.pl -H $HOSTADDRESS$ -C $ARG1$ -i $ARG2$ -M $ARG3$ -I $ARG3$ -O $ARG4$ -u m -b $ARG5$ -B

Template is named check_band_usage3_copy_1.php ( which is a requirement for it to work )

Everything seems to be working fine inside nagvis, template works ( pleas see attached file nagvis-working template.JPG )
The problem is when i click on link and graph is displayed inside nagios, its empty ( see attached file nagios-empty graph template.JPG)
There is more info in attached graphapi.log and Gi0_0_2_-_link_do_MPLS_Netia_copy6.rrd file.

What goes wrong here ?

This is just a guess since I haven't been able to fully reproduce the problem and this was developed by a third party, but the command seems to have a problem with not escaping the parentheses around time and usageIN. Try changing line 122 and 123 in the template.

From:

Code: Select all

	# Determine time increments used in graph
	$def[1] .= "CDEF:time=PREV(usageIN),POP,TIME ";
	$def[1] .= "CDEF:prevtime=PREV(time) ";

to:

Code: Select all

	# Determine time increments used in graph
	$def[1] .= "CDEF:time=PREV\(usageIN\),POP,TIME ";
	$def[1] .= "CDEF:prevtime=PREV\(time\) ";

Restart the httpd service(service httpd restart) and refresh the browser.

After this change graph is working in Nagios, but in Nagvis is blank. Maybe you can recommend some other template with similar functionality?

[cdienger]

Well dang.

Another possible option disabling the highchart which may be having problems with the escaping. Do this under Admin > System Config > System Settings > Theme & Display, and uncheck the "Use Highcharts for Performance Graphs page and host/service detail pages (host/service popup graph always uses Highcharts)" option. You then would want to revert the template file to its initial state.

[Eurocash]

We have this option already unchecked, it was necessary for template to work. On modified template - Nagios graph OK, Nagvis graph empty, on origianl template - Nagios graph empty, Nagvis graph OK.

Is there anything logged in the apache logs(/var/log/httpd/) when it's broken in either Nagios or Nagvis?

I'd also like to get a fresh copy of the rrd and its respective xml to try and reproduce this again.

The Nagios graphs worked right off the bat using the unaltered template on my test system(CentOS 6.8 php 5.3.3). What OS is your system and php version? I know that some older php versions have had issues with nested quotes. Supported php versions are 5.3, 5.4, 5.5, and 5.6. You can try upgrading to a newer version using "yum upgrade php".

All good:
