PNP4Nagios All Values the same

jpl · Post by **jpl** » Wed Nov 06, 2019 11:14 am

Having a weird problem with PNP4Nagios. In my memory graphs all the values for the different things (cache, buffers, total mem, used mem, etc...) are all the same value...the total memory value. Nagios version 3.5.1 and PNP v0.6.26.The template has 4 data sources defined:

$ds_name[1] = "sysinfo";
$opt[1] = "--vertical-label \"Bytes\" -l0 --title \"Memory usage for $hostname / $servicedesc\" ";
# Total Memory
$def[1] = "DEF:mem_total=$RRDFILE[1]:$DS[1]:AVERAGE " ;
# Used Memory
$def[1] .= "DEF:mem_used=$RRDFILE[1]:$DS[2]:AVERAGE " ;
# Cache
$def[1] .= "DEF:mem_cache=$RRDFILE[1]:$DS[3]:AVERAGE " ;
# Buffer
$def[1] .= "DEF:mem_buffer=$RRDFILE[1]:$DS[4]:AVERAGE " ;

The output of the check command looks like:

MEMORY OK - Total: 3789 MB - Used: 3003 MB - 79% used|TOTAL=3973943296;;;0;3973943296 USED=3149709312;3179154432;3576548352;0;3973943296 CACHE=616673280;;;0;3973943296 BUFFER=0;;;0;3973943296

The XML file in the perfdata folder has the same value (max memory in the system) in the <MAX></MAX> tag and I see the proper values in the <ACT></ACT> tags however the graph does not show those values.

Sample image attached.

Is this the whole template? You aren't showing any GPRINT lines... Please share the whole template.

We will try to help, but PNP4Nagios is not our project and more information can be found here

I'm asking here because I don't see any forums or anything on the PNP4Nagios website. Here is the rest of the template:

Code: Select all

# Memory Cache
        $def[1] .= rrd::cdef("mem_cache_tmp", "mem_cache,mem_buffer,+,mem_used,+");
        $def[1] .= rrd::area("mem_cache_tmp", "#DCDDD5", "Disk Cache");
        $def[1] .= "GPRINT:mem_cache:LAST:\"%3.2lf %sB Last \" ";
        $def[1] .= "GPRINT:mem_cache:MAX:\"%3.2lf %sB Max \" ";
        $def[1] .= "GPRINT:mem_cache" . ':AVERAGE:"%3.2lf %sB Average \j" ';
        # Memory Buffer
        $def[1] .= rrd::cdef("mem_buffer_tmp", "mem_buffer,mem_used,+");
        $def[1] .= rrd::area("mem_buffer_tmp", "#3E606F", "I/O Buffers");
        $def[1] .= "GPRINT:mem_buffer:LAST:\"%3.2lf %sB Last \" ";
        $def[1] .= "GPRINT:mem_buffer:MAX:\"%3.2lf %sB Max \" ";
        $def[1] .= "GPRINT:mem_buffer" . ':AVERAGE:"%3.2lf %sB Average \j" ';
        # Memory Used
        $def[1] .= rrd::area("mem_used", "#193441", "Processes");
        $def[1] .= "GPRINT:mem_used:LAST:\"%3.2lf %sB Last \" ";
        $def[1] .= "GPRINT:mem_used:MAX:\"%3.2lf %sB Max \" ";
        $def[1] .= "GPRINT:mem_used" . ':AVERAGE:"%3.2lf %sB Average \j" ';
        # Memory Total
        $def[1] .= rrd::line1("mem_total", "#000000", "Total");
        $def[1] .= "GPRINT:mem_total:LAST:\"%3.2lf %sB Last \" ";
        $def[1] .= "GPRINT:mem_total:MAX:\"%3.2lf %sB Max \" ";
        $def[1] .= "GPRINT:mem_total" . ':AVERAGE:"%3.2lf %sB Average \j" ';
        if ($WARN[2] != "") {
                $def[1] .= "HRULE:$WARN[2]#ffff00:\"Warning threshold for Processes\j\" ";
        }
        if ($CRIT[2] != "") {
                $def[1] .= "HRULE:$CRIT[2]#ff0000:\"Critical threshold for Processes\" ";
        }
?>

These look correct, but again we have limited knowledge of PNP v0.6.26

Is it possible that this check could be picking up a different template?

No, because if I break the template it complains about the same file I change. It's definitely using the template.

In the generated XML here is the reference to the tmeplate:

Code: Select all

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<NAGIOS>
  <DATASOURCE>
    <TEMPLATE>check_linux_mem</TEMPLATE>

check_linux_mem.php is the name of the template file in the templates folder.

Hmm.

I'll leave the topic open in case a community member has encountered this and can chime in, but I would still recommend contacting the projest author

If I find a solution I will post it here as well.
