[Check_mk (english)] pnp4nagios interface graphs

[James Cook]

After updating to PHP 7.2 on Centos 7 I discovered that pnp4nagios would no longer display network interface graphs for linux hosts. This issue appears to be caused by $WARN[1] and $CRIT[1] not being set so they are not numeric values. I added the code below to work around the problem to etc/pnp4nagios/templates/check_mk-lnx_if.php (just before the "# Convert bytes to bits if necessary" line).



if(!is_numeric($WARN[1])) {

$warn=0;

}

if(!is_numeric($CRIT[1])) {

$crit=0;

}



This is in check_mk raw 1.5.0p5 with pnp4nagios 0.6.26.

Hope this helps someone else.
