Specifically, HP printers that have internal/external JetDirect cards/devices, or other print servers (like the Troy PocketPro 100S or the Netgear PS101) that support the JetDirect protocol. </p> <p> The <i>check_hpjd</i> plugin (which is part of the standard Nagios plugins distribution) allows you to monitor the status of JetDirect-capable printers which have SNMP enabled. The plugin is capable of detecting the following printer states: </p> <p> <ul> <li>Paper Jam</li> <li>Out of Paper</li> <li>Printer Offline</li> <li>Intervention Required</li> <li>Toner Low</li> <li>Insufficient Memory</li> <li>Open Door</li> <li>Output Tray is Full</li> <li>and more...</li> </ul> </p> <p> <img src="images/note.gif" border="0" align="bottom"> Notes: </p> <p> <ul> <li>These instructions assume that you've installed Nagios according to the <a href="quickstart.html">quickstart guide</a>. The sample configuration entries below reference objects that are defined in the sample <i>commands.cfg</i> and <i>localhost.cfg</i> config files.</li><br><br> <li>For your convenience, the configuration examples given below can be found in a sample <i>printer.cfg</i> config file that gets installed when you following the quickstart guide. After reading these instructions, just edit the <i>printer.cfg</i> file to custom the host name, IP address, etc. and uncomment the reference to the <i>printer.cfg</i> file in the <i>nagios.cfg</i> file.</li><br><br> <li>The <i>check_hpjd</i> plugin will only get compiled and installed if you have the net-snmp and net-snmp-utils packages installed on your system. Make sure the plugin exists in <i>/usr/local/nagios/libexec</i> before you continue. If it doesn't, install net-snmp and net-snmp-utils and recompile/reinstall the Nagios plugins.</li> </ul> </p> <p> <strong><u>Creating Required Definitions</u></strong> </p> <p> You'll need to create some <a href="objectdefinitions.html">object definitions</a> in order to monitor a new printer. These definitions can be placed in their own file or added to an already exiting object configuration file. </p> <p> First, its best practice to create a new template for each different type of host you'll be monitoring. Let's create a new template for printers. </p> <p> <pre> define host{ name generic-printer ; The name of this host template use generic-host ; Inherit default values from the generic-host template check_period 24x7 ; By default, printers are monitored round the clock check_interval 5 ; Actively check the printer every 5 minutes retry_interval 1 ; Schedule host check retries at 1 minute intervals max_check_attempts 10 ; Check each printer 10 times (max) check_command check-host-alive ; Default command to check if printers are "alive" notification_period workhours ; Printers are only used during the workday notification_interval 30 ; Resend notifications every 30 minutes notification_options d,r ; Only send notifications for specific host states contact_groups admins ; Notifications get sent to the admins by default register 0 ; DONT REGISTER THIS - ITS JUST A TEMPLATE } </pre> </p> <p> Notice that the printer template definition is inheriting default values from the <i>generic-host</i> template, which is defined in the sample <i>localhost.cfg</i> file. </p> <p> Next, define a new <a href="objectdefinitions.html#host">host</a> for the printer that references the newly created <i>generic-printer</i> host template. </p> <p> <pre> define host{ use generic-printer ; Inherit default values from a template host_name hplj2605dn ; The name we're giving to this printer alias HP LaserJet 2605dn ; A longer name associated with the printer address 192.168.1.30 ; IP address of the printer hostgroups allhosts ; Host groups this printer is associated with } </pre> </p> <p> Add an optional <a href="objectdefinitions.html#hostgroup">hostgroup</a> for printers. This is useful if you create additional printers in the future and want to view them together in the CGIs. It can also be useful for <a href="objecttricks.html">object definition tricks</a> that you can use to manage larger configurations later on. </p> <p> <pre> define hostgroup{ hostgroup_name laserjet-printers ; The name of the hostgroup alias HP LaserJet Printers ; Long name of the group members hplj2605dn ; Comma separated list of hosts that belong to this group } </pre> </p> <p> The <i>hplj2605dn</i> host will be a member of two hostgroups - <i>allhosts</i> (which is referenced in the host definition and defined in <i>localhost.cfg</i>) and <i>laserjet-printers</i> (which is defined above). </p> <p> Now its time to define some <a href="objectdefinitions.html#service">services</a> that should be associated with the printer. As mentioned earlier, the <i>check_hpjd</i> plugin allows you to monitor the current state of the printer. Let's use that plugin to define a service. Before we do that, it should be noted that there is already a <a href="objectdefinitions.html#command">command definition</a> for using the <i>check_hpjd</i> plugin in service checks that has been defined in the <i>commands.cfg</i> file. That command definition looks like this... </p> <p> <pre> define command{ command_name check_hpjd command_line $USER1$/check_hpjd -H $HOSTADDRESS$ $ARG1$ } </pre> </p> <p> Let's create a service called <i>Printer Status</i> as follows... </p> <p> <pre> define service{ use generic-service ; Inherit values from a template host_name hplj2605dn ; The name of the host the service is associated with service_description Printer Status ; The service description check_command check_hpjd!-C public ; The command used to monitor the service normal_check_interval 10 ; Check the service every 10 minutes under normal conditions retry_check_interval 1 ; Re-check the service every minute until its final/hard state is determined } </pre> </p> <p> Notice that the <i>check_command</i> directive is passing "-C public" to the <i>check_hpjd</i> command. That argument gets put into the <i>$ARG1$</i> macro in the command definition and tells the plugin that it should use an SNMP community string of "public" when checking the status of the printer. </p> <p> That's it! You've just configured a new printer that should be monitored by Nagios.
