5 ### <a id="addons-graphing-pnp"></a> PNP
7 [PNP](http://www.pnp4nagios.org) is a graphing addon.
9 [PNP](http://www.pnp4nagios.org) is an addon which adds a graphical representation of the performance data collected
10 by the monitoring plugins. The data is stored as rrd (round robin database) files.
12 Use your distribution's package manager to install the `pnp4nagios` package.
14 If you're planning to use it configure it to use the
15 [bulk mode with npcd and npcdmod](http://docs.pnp4nagios.org/pnp-0.6/modes#bulk_mode_with_npcd_and_npcdmod)
16 in combination with Icinga 2's [PerfdataWriter](4-advanced-topics.md#performance-data). NPCD collects the performance
17 data files which Icinga 2 generates.
19 Enable performance data writer in icinga 2
21 # icinga2 feature enable perfdata
23 Configure npcd to use the performance data created by Icinga 2:
25 vim /etc/pnp4nagios/npcd.cfg
27 Set `perfdata_spool_dir = /var/spool/icinga2/perfdata` and restart the `npcd` daemon.
29 There's also an Icinga Web 2 module for direct PNP graph integration
30 available at https://exchange.icinga.org/icinga/PNP4Nagios

33 and [graph template names](13-addons-plugins.md#addons-graphing-pnp-custom-templates).
36 ### <a id="addons-graphing-graphite"></a> Graphite
38 [Graphite](http://graphite.readthedocs.org/en/latest/) is a time-series database
39 storing collected metrics and making them available through restful apis
42 Graphite consists of 3 software components:
44 * carbon - a Twisted daemon that listens for time-series data
45 * whisper - a simple database library for storing time-series data (similar in design to RRD)
46 * graphite webapp - A Django webapp that renders graphs on-demand using Cairo
48 Use the [GraphiteWriter](4-advanced-topics.md#graphite-carbon-cache-writer) feature
49 for sending real-time metrics from Icinga 2 to Graphite.
51 # icinga 2 feature enable graphite
53 There are Graphite addons available for collecting the performance data files too (e.g. `Graphios`).
55 ### <a id="addons-graphing-ingraph"></a> inGraph
57 [inGraph](https://www.netways.org/projects/ingraph/wiki) requires the ingraph-collector addon
58 to be configured to point at the perfdata files. Icinga 2's [PerfdataWriter](4-advanced-topics.md#performance-data) will
59 write to the performance data spool directory.
61 ## <a id="addons-visualization"></a> Visualization
63 ### <a id="addons-visualization-reporting"></a> Icinga Reporting
65 By enabling the DB IDO feature you can use the Icinga Reporting package.
67 ### <a id="addons-visualization-nagvis"></a> NagVis
69 By using either Livestatus or DB IDO as a backend you can create your own network maps
70 based on your monitoring configuration and status data using [NagVis](http://www.nagvis.org).
72 ### <a id="addons-visualization-thruk"></a> Thruk
74 [Thruk](http://www.thruk.org) is an alternative web interface which can be used with Icinga 2.
76 ## <a id="log-monitoring"></a> Log Monitoring
78 Using Logstash or Graylog in your infrastructure and correlate events with your monitoring
79 is even simpler these days.
81 * Use the `GelfWriter` feature to write Icinga 2's check and notification events to Graylog or Logstash.
82 * Configure the logstash `nagios` output to send passive traps to Icinga 2 using the external command pipe.
83 * Execute a plugin to check Graylog alert streams.
85 More details can be found in [this blog post](https://www.icinga.org/2014/12/02/team-icinga-at-osmc-2014/).
87 ## <a id="configuration-tools"></a> Configuration Management Tools
89 If you require your favourite configuration tool to export Icinga 2 configuration, please get in
90 touch with their developers. The Icinga project does not provide a configuration web interface
91 yet. Follow the [Icinga Blog](https://www.icinga.org/blog/) for updates on this topic.
93 If you're looking for puppet manifests, chef cookbooks, ansible recipes, etc - we're happy
94 to integrate them upstream, so please get in touch at [https://support.icinga.org](https://support.icinga.org).
96 These tools are currently in development and require feedback and tests:
98 * [Ansible Roles](https://github.com/Icinga/icinga2-ansible)
99 * [Puppet Module](https://github.com/Icinga/puppet-icinga2)
100 * [Chef Cookbook](https://github.com/Icinga/chef-icinga2)
103 ## <a id="plugins"></a> Plugins
105 For some services you may need additional 'check plugins' which are not provided
106 by the official Monitoring Plugins project.
108 All existing Nagios or Icinga 1.x plugins work with Icinga 2. Here's a
109 list of popular community sites which host check plugins:
111 * [Icinga Exchange](https://exchange.icinga.org)
112 * [Icinga Wiki](https://wiki.icinga.org)
114 The recommended way of setting up these plugins is to copy them to a common directory
115 and create a new global constant, e.g. `CustomPluginDir` in your [constants.conf](5-configuring-icinga-2.md#constants-conf)
118 # cp check_snmp_int.pl /opt/monitoring/plugins
119 # chmod +x /opt/plugins/check_snmp_int.pl
121 # cat /etc/icinga2/constants.conf
123 * This file defines global constants which can be used in
124 * the other configuration files. At a minimum the
125 * PluginDir constant should be defined.
128 const PluginDir = "/usr/lib/nagios/plugins"
129 const CustomPluginDir = "/opt/monitoring/plugins"
131 Prior to using the check plugin with Icinga 2 you should ensure that it is working properly
132 by trying to run it on the console using whichever user Icinga 2 is running as:
134 # su - icinga -s /bin/bash
135 $ /opt/monitoring/plugins/check_snmp_int.pl --help
137 Additional libraries may be required for some plugins. Please consult the plugin
138 documentation and/or plugin provided README for installation instructions.
139 Sometimes plugins contain hard-coded paths to other components. Instead of changing
140 the plugin it might be easier to create logical links which is (more) update-safe.
142 Each plugin requires a [CheckCommand](6-object-types.md#objecttype-checkcommand) object in your
143 configuration which can be used in the [Service](6-object-types.md#objecttype-service) or
144 [Host](6-object-types.md#objecttype-host) object definition.
146 There are the following conventions to follow when adding a new command object definition:
148 * Always import the `plugin-check-command` template
149 * Use [command-arguments](#) whenever possible. The `command` attribute must be an array
150 in `[ ... ]` then for shell escaping.
151 * Define a unique `prefix` for the command's specific command arguments. That way you can safely
152 set them on host/service level and you'll always know which command they control.
153 * Use command argument default values, e.g. for thresholds
154 * Use [advanced conditions](6-object-types.md#objecttype-checkcommand) like `set_if` definitions.
156 Example for a custom `my-snmp-int` check command:
158 object CheckCommand "my-snmp-int" {
159 import "plugin-check-command"
161 command = [ CustomPluginDir + "/check_snmp_int.pl" ]
164 "-H" = "$snmp_address$"
165 "-C" = "$snmp_community$"
170 "-n" = "$snmp_interface$"
172 set_if = "$snmp_perf$"
179 vars.snmp_perf = true
180 vars.snmp_warn = "300,400"
181 vars.snmp_crit = "0,600"
184 Icinga 2 has built-in check command definitions for the [Manubulon Plugin Checks](7-icinga-template-library.md#snmp-manubulon-plugin-check-commands).
186 For further information on your monitoring configuration read the
187 [Monitoring Basics](3-monitoring-basics.md#monitoring-basics) chapter.
189 You can find additional plugins at the [Icinga Exchange](https://exchange.icinga.org)
191 More details on the plugins can also be found on the Icinga Wiki at https://wiki.icinga.org
193 ## <a id="plugin-api"></a> Plugin API
195 Currently Icinga 2 supports the native plugin API specification from the `Monitoring Plugins`
198 The `Monitoring Plugin API` is defined in the [Monitoring Plugins Development Guidelines](https://www.monitoring-plugins.org/doc/guidelines.html).
200 There are no output length restrictions using Icinga 2. This is different to the
201 [Icinga 1.x plugin api definition](http://docs.icinga.org/latest/en/pluginapi.html#outputlengthrestrictions).
204 ## <a id="addon-integration-hints"></a> More Addon Integration Hints
206 ### <a id="addons-graphing-pnp-action-url"></a> PNP Action Url
208 They work in a similar fashion for Icinga 2 and are used for 1.x web interfaces (Icinga Web 2 doesn't require
209 the action url attribute in its own module).
211 template Service "pnp-hst" {
212 action_url = "/pnp4nagios/graph?host=$HOSTNAME$"
215 template Service "pnp-svc" {
216 action_url = "/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$"
219 ### <a id="addons-graphing-pnp-custom-templates"></a> PNP Custom Templates with Icinga 2
221 PNP automatically determines the graph template from the check command name (or the argument's name).
222 This behavior changed in Icinga 2 compared to Icinga 1.x. Though there are certain possibilities to
225 * Create a symlink for example from the `templates.dist/check_ping.php` template to the actual check name in Icinga 2 (`templates/ping4.php`)
226 * Pass the check command name inside the [format template configuration](4-advanced-topics.md#writing-performance-data-files)
228 The latter becomes difficult with agent based checks like NRPE or SSH where the first command argument acts as
229 graph template identifier. There is the possibility to define the pnp template name as custom attribute
230 and use that inside the formatting templates as `SERVICECHECKCOMMAND` for instance.
232 Example for services:
234 # vim /etc/icinga2/features-enabled/perfdata.conf
236 service_format_template = "DATATYPE::SERVICEPERFDATA\tTIMET::$icinga.timet$\tHOSTNAME::$host.name$\tSERVICEDESC::$service.name$\tSERVICEPERFDATA::$service.perfdata$\tSERVICECHECKCOMMAND::$service.check_command$$pnp_check_arg1$\tHOSTSTATE::$host.state$\tHOSTSTATETYPE::$host.state_type$\tSERVICESTATE::$service.state$\tSERVICESTATETYPE::$service.state_type$"
238 # vim /etc/icinga2/conf.d/services.conf
240 template Service "pnp-svc" {
241 action_url = "/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$"
242 vars.pnp_check_arg1 = ""
245 apply Service "nrpe-check" {
248 vars.nrpe_command = "check_disk"
250 vars.pnp_check_arg1 = "!$nrpe_command$"
253 If there are warnings about unresolved macros make sure to specify a default value for `vars.pnp_check_arg1` inside the
255 In PNP, the custom template for nrpe is then defined in `/etc/pnp4nagios/custom/nrpe.cfg`
256 and the additional command arg string will be seen in the xml too for other templates.
