5 ### PNP <a id="addons-graphing-pnp"></a>
7 [PNP](https://www.pnp4nagios.org) is a graphing addon.
9 [PNP](https://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](https://docs.pnp4nagios.org/pnp-0.6/modes#bulk_mode_with_npcd_and_npcdmod)
16 in combination with Icinga 2's [PerfdataWriter](14-features.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 [Icinga Exchange](https://exchange.icinga.com/icinga/PNP).

33 and [graph template names](13-addons.md#addons-graphing-pnp-custom-templates).
36 ### Graphite <a id="addons-graphing-graphite"></a>
38 [Graphite](https://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](14-features.md#graphite-carbon-cache-writer) feature
49 for sending real-time metrics from Icinga 2 to Graphite.
51 # icinga2 feature enable graphite
53 There are Graphite addons available for collecting the performance data files too (e.g. `Graphios`).
55 A popular alternative frontend for Graphite is for example [Grafana](https://grafana.org).
57 ### InfluxDB <a id="addons-graphing-influxdb"></a>
59 [InfluxDB](https://influxdb.com) is a time series, metrics, and analytics database.
60 It’s written in Go and has no external dependencies.
62 Use the [InfluxdbWriter](14-features.md#influxdb-writer) feature
63 for sending real-time metrics from Icinga 2 to InfluxDB.
65 # icinga2 feature enable influxdb
67 A popular frontend for InfluxDB is for example [Grafana](https://grafana.org).
69 ## Visualization <a id="addons-visualization"></a>
71 ### Icinga Reporting <a id="addons-visualization-reporting"></a>
73 By enabling the [DB IDO](14-features.md#db-ido) feature you can use the
74 [Icinga Reporting package](https://icinga.com/docs/icinga1/latest/en/reporting.html).
76 ### NagVis <a id="addons-visualization-nagvis"></a>
78 By using either [Livestatus](14-features.md#setting-up-livestatus) or
79 [DB IDO](14-features.md#db-ido) as a backend you can create your own network maps
80 based on your monitoring configuration and status data using [NagVis](https://www.nagvis.org).
82 The configuration in nagvis.ini.php should look like this for Livestatus for example:
85 backendtype="mklivestatus"
86 socket="unix:/var/run/icinga2/cmd/livestatus"
88 If you are planning an integration into Icinga Web 2, look at [this module](https://github.com/Icinga/icingaweb2-module-nagvis).
90 ### Thruk <a id="addons-visualization-thruk"></a>
92 [Thruk](https://www.thruk.org) is an alternative web interface which can be used with Icinga 2
93 and the [Livestatus](14-features.md#setting-up-livestatus) feature.
95 ## Log Monitoring <a id="log-monitoring"></a>
97 Using [Logstash](https://www.elastic.co/guide/en/logstash/current/introduction.html) or
98 [Graylog](https://www.graylog.org) in your infrastructure and correlate events with your monitoring
99 is even simpler these days.
101 * Use the `GelfWriter` feature to write Icinga 2's check and notification events to Graylog or Logstash.
102 * Configure the logstash `nagios` output to send passive traps to Icinga 2 using the external command pipe.
103 * Execute a plugin to check Graylog alert streams.
105 More details can be found in [this blog post](https://icinga.com/2014/12/02/team-icinga-at-osmc-2014/).
107 ## Notification Scripts and Interfaces <a id="notification-scripts-interfaces"></a>
109 There's a variety of resources available, for example different notification scripts such as:
111 * E-Mail ([examples](03-monitoring-basics.md#alert-notifications) provided)
119 Additionally external services can be [integrated with Icinga 2](https://icinga.com/products/integrations/):
121 * [Pagerduty](https://icinga.com/products/integrations/pagerduty/)
122 * [VictorOps](https://icinga.com/products/integrations/victorops/)
123 * [StackStorm](https://icinga.com/products/integrations/stackstorm/)
125 More information can be found on the [Icinga Website](https://icinga.com/).
127 ## Configuration Management Tools <a id="configuration-tools"></a>
129 If you require your favourite configuration tool to export the Icinga 2 configuration, please get in
130 touch with their developers. The Icinga project does not provide a configuration web interface
131 yet. Follow the [Icinga Blog](https://icinga.com/blog/) for updates on this topic.
133 If you're looking for puppet manifests, chef cookbooks, ansible recipes, etc. -- we're happy
134 to integrate them upstream, so please get in touch with the [Icinga team](https://icinga.com/community/).
136 These tools are currently in development and require feedback and tests:
138 * [Ansible Roles](https://github.com/Icinga/icinga2-ansible)
139 * [Puppet Module](https://github.com/Icinga/puppet-icinga2)
140 * [Chef Cookbook](https://github.com/Icinga/chef-icinga2)
142 ## More Addon Integration Hints <a id="addon-integration-hints"></a>
144 ### PNP Action Url <a id="addons-graphing-pnp-action-url"></a>
146 They work in a similar fashion for Icinga 2 and are used for 1.x web interfaces (Icinga Web 2 doesn't require
147 the action url attribute in its own module).
149 template Host "pnp-hst" {
150 action_url = "/pnp4nagios/graph?host=$HOSTNAME$"
153 template Service "pnp-svc" {
154 action_url = "/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$"
157 ### PNP Custom Templates with Icinga 2 <a id="addons-graphing-pnp-custom-templates"></a>
159 PNP automatically determines the graph template from the check command name (or the argument's name).
160 This behavior changed in Icinga 2 compared to Icinga 1.x. Though there are certain possibilities to
163 * Create a symlink for example from the `templates.dist/check_ping.php` template to the actual check name in Icinga 2 (`templates/ping4.php`)
164 * Pass the check command name inside the [format template configuration](14-features.md#writing-performance-data-files)
166 The latter becomes difficult with agent based checks like NRPE or SSH where the first command argument acts as
167 graph template identifier. There is the possibility to define the pnp template name as custom attribute
168 and use that inside the formatting templates as `SERVICECHECKCOMMAND` for instance.
170 Example for services:
172 # vim /etc/icinga2/features-enabled/perfdata.conf
174 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$"
176 # vim /etc/icinga2/conf.d/services.conf
178 template Service "pnp-svc" {
179 action_url = "/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$"
180 vars.pnp_check_arg1 = ""
183 apply Service "nrpe-check" {
186 vars.nrpe_command = "check_disk"
188 vars.pnp_check_arg1 = "!$nrpe_command$"
191 If there are warnings about unresolved macros, make sure to specify a default value for `vars.pnp_check_arg1` inside the
193 In PNP, the custom template for nrpe is then defined in `/etc/pnp4nagios/custom/nrpe.cfg`
194 and the additional command arg string will be seen in the xml too for other templates.
