Fixing the monitoring hosts > hosts view in centreon 2.1.4

When opening the Monitoring > Hosts > Hosts view to view all the available and configured hosts in Centreon 2.1.4 you will get a blank result. This happens because there is a coding error in the following file.

/usr/local/centreon/www/include/monitoring/status/Hosts/xml/hostXML.php on line 249

To correct it you need to add a else statement to the if, elseif validation that happens there. So open the file listed above using your fav. editor (vim in my case)

vim /usr/local/centreon/www/include/monitoring/status/Hosts/xml/hostXML.php

Version 2.1.4

Skip to line 249 typing ” :249 ” followed by an enter stroke.
On that line there should be something like;

if (($ndo["last_hard_state_change"] > 0) && ($ndo["last_hard_state_change"] >= $ndo["last_state_change"]))
                        $hard_duration = Duration::toString(time() - $ndo["last_hard_state_change"]);
                else if ($ndo["last_hard_state_change"] > 0)
                        $hard_duration = " N/A ";

Change it to this by adding the part starting from “else”.

if (($ndo["last_hard_state_change"] > 0) && ($ndo["last_hard_state_change"] >= $ndo["last_state_change"]))
                        $hard_duration = Duration::toString(time() - $ndo["last_hard_state_change"]);
                else if ($ndo["last_hard_state_change"] > 0)
                        $hard_duration = " N/A ";
                else
                        $hard_duration = " unknown ";

Version 2.1.8

Goto rule 272 in the same file and locate this piece of code:

if (($ndo["last_hard_state_change"] > 0) && ($ndo["last_hard_state_change"] >= $ndo["last_state_change"]))
                        $hard_duration = Duration::toString(time() - $ndo["last_hard_state_change"]);
                else if ($ndo["last_hard_state_change"] > 0)
                        $hard_duration = " N/A ";

Add the following to make it work.

if (($ndo["last_hard_state_change"] > 0) && ($ndo["last_hard_state_change"] >= $ndo["last_state_change"]))
                        $hard_duration = Duration::toString(time() - $ndo["last_hard_state_change"]);
                else if ($ndo["last_hard_state_change"] > 0)
                        $hard_duration = " N/A ";
                else
                        $hard_duration = "N/A";

This same rule is responsible for the following errors in your apache error_log.

PHP Notice: Undefined variable: hard_duration in /usr/local/centreon/www/include/monitoring/status/Hosts/xml/hostXML.php on line 271, referer: http://centreon.amis.nl/centreon/main.php?p=20102&o=h

This change should fix it for ya.

Grtz, Chris.
