Nagios event_broker_options
Starting with version 0. The sourcecode is already available on sourceforge. The output of a nagios plugin up to nagios 2. When the plugin produces performance data, it is divided into two parts. Performance data is designed for automatic processing. The format is specified within the Developer Guidelines you'll find an excerpt here but should be exemplified here nonetheless:. Several data series are separated by blanks. The actual data must not contains any blanks.
If the label contains blanks, it has to be surrounded by single quotes. PNP is licensed under GPL 2. Development of PNP is organized using Sourceforge. The current stable version of 0. The current development can be viewed anytime at https: PRIOR to support questions please make sure that you have verified certain things described under verify your installation.
The developers and helpers are present on a separate board at http: Postings in english will be answered as well. After registering as a user please fill in the profile regarding operating system and PNP version used. Please mention if you used a package or compiled the sources.
Please state your operating system and PNP version. Performance data will be stored in Round Robin Databases using RRDtool. Various intervals provide for different resolutions. Using the defaults allows to store the data with a resolution of one minute for the last two days, five minutes resolution for ten days, 30 minutes resolution for 90 days and 6 hours resolution for four years.
The increasing interval causes averaging of the data which leads to smaller max values. This not an error of PNP. Using this storage format the size of the files will stay the same over time. Per datasource you will need approx. PNP supports several modes to process performance data. The modes differ in complexity and the performance to be expected. Nagios invokes a command for every host and every service whose performance data should be processed. Before you choose a mode please read the documentation and decide which way will be the best for installation.
The synchronous mode will work very good up to about 1. In bulk mode Nagios writes the necessary data to a temporary file. After expiration of a defined time the file will be processed in one piece and deleted afterwards. Depending on time and the amount of collected data there will be much less system calls. While it is running to process data nagios will not execute any checks.
This will be the data volume of about services und processing using a 10 second interval. It means we blocked nagios for exactly 0. Viewing from Nagios this is the best way of processing because Nagios will not be blocked. Nagios again uses a temporary file to store the data and executes a command after expiration of a certain time.
As moving a file inside the same filesystem nearly takes no time nagios is able to execute crucial work immediately. Processing of performance data is decoupled completely from nagios. NPCD itself is able to start multiple thread for processing the data. Attention Starting with Nagios 4 the internal structures have changed so the start of the module will fail. So far there are no plans to support Nagios 4. Please select any other of the modes. This scenario includes npcdmod.
Nagios and PNP4Nagios can be run on different machines. Which mode you choose will depend on the size of your Nagios installation. You will find theses terms throughout the documentation. Changes can be tracked on pnp4nagios. The current Version is pnp4nagios The web-frontend has been completely rewritten and is now based on the PHP MVC framework Kohana. This leads to changed dependencies which must be checked prior to installation. At first an upgrade is like a new installation.
Afterwards some changes should be made which are described further down. Without specifying any options during.
The internal structure of the xml files has changed so you wouldn't be able to use them either way. Other than described in the 0. The variables in the files in the templates folder have to be initialised before first use.
Earlier you were able to append to variables which weren't initialised before first use. Constants in template files don't work anymore, so that they have to be converted to variables. Please keep in mind that all occurrences have to be changed. The installation of PNP will be described in more detail. The description applies to the developer version PNP 0. Please note that PNP has to be configured after the installation. The installation of PNP is controlled by makefile s. The system is analyzed after invocation of.
Using Icinga the call might be. The paths shown should be checked. If the displayed values aren't correct you can change them calling. If necessary it can be specified using the following syntax:. The paths were already shows during. After the installation of the program and HTML files you can copy a sample Apache configuration file to your web-server config directory. As already stated the Nagios settings will be used per default.
The update of a 0. Please note that you have to call. If you changed config. You can skip make install-webconf and make install-init because nothing changed between 0. After installation the components of PNP were copied to the appropriate places in the file system.
The configuration of the already mentioned modes of performance data processing will be described in more detail. Every event will trigger an execution of process-service-perfdata. Initially you have to enable processing of performance data in nagios. Please note that this directive might already exist in the config file.
Data processing has to be disabled in the definition of every host or service whose performance data should NOT be processed. Unfortunately this directive has to be enabled to use the synchronous mode. So either you use the default value which means that the export is enabled or you define the variable in nagios.
Additionally the command to process performance data is to be specified in nagios. Starting with Nagios 3. Due to changed host check logic Nagios 3 now performs regularly scheduled host checks.
Nagios has to be notified about the referenced commands as well. If you used the quickstart installation guides for Nagios you can modify the definitions in commands.
If you use Nagios 3. In bulk mode Nagios writes the data to a temporary file in a defined format. Nagios will take care for starting and running it periodically. Please note that these template definitions differ from the ones delivered in nagios.
The used commands have to be announced to Nagios. The configuration is identical to the Bulk Mode except for the used command. Processing of performance data has to be enabled in nagios. This way processing of performance data is completely decoupled from nagios. The only thing that remains is to start NPCD. This mode uses the event broker module npcdmod.
Make sure that the resultung value has these bits set because otherwise there will be no performance data to process. Default is an activated encyrption which should be changed only in special cases. If everything went well until now you can try to call PNP using your web browser. When using the installation with default values PNP should be called using http: Obviously all checks have to be passed successfully before you can proceed.
Please follow the instructions given on that page. Not till then the web interface is reachable. Immediately after re- starting Nagios after you enabled nagios event_broker_options processing of performance data you will get error messages in your browser because performance data has to be collected and stored in RRD files. Depending on the check interval you are using you have to wait some time before you can view the first graphs.
Most likely we will ask for excerpts from perfdata. During normal operation the debug level should be set to 0 to avoid performance issues due to unnecessary entries in the log file. Have any RRD and XML files been created? In this directory an RRD database and an XML file will be created for every service. If graphing stops out of a sudden then open the appropriate XML file. Sometimes you fx options expiry time to specify additional options so that performance data is produced.
In some cases a euro to sterling exchange rate in ireland script might help.
However not all checks provide performance data. If it is empty there is no data available so no files are written to the appropriate directory and that is why PNP does not provide you with graphs! The output of the plugin is surrounded by a blue border, the performance data by a red one. Graphs are shown without text? Have a look at the requirements.
Wait until the xml file is newly created and retry. Using the npcdmod module the value of the nagios. You'll find some details here.
That will increase the size of the spool directory and slow down performance data processing. It enables you to check the configuration settings as well as performance ddd stock after hours of hosts or services.
MK Livestatus
It can be used prior and during runtime of PNP. It ONLY supports verifying Nagios 3. The verify script is located on http: Nagios itself features external URLs using so called extended info configs.
Due to forex global logistics between Nagios 2. This way the presidential election futures trading of URLs to the PNP-interface has been simplified.
The serviceextinfo and hostextinfo definitions are deprecated. First two nagios templates are defined. If you used the Nagios quickstart installation guides you can append these lines to templates. If you used the quickstart installation guide you might for example edit the file localhost.
You can integrate PNP into Nagios in a way that you have current graphs without clicking any icons. This can be accomplished using the CGI Includes which allow us to include JavaScript code in the status detail view status. After a restart of Nagios after modifying the definitions the result might look like this: This file will be overwritten during updates of PNP as the paths and options are detected during. If this get selected option in dropdown jquery does not exist the file config.
Screen sizes may vary, pages sizes won't. The following two directives enable you to specify different sizes for the creation of PDFs.
If they aren't specified the values of the graph sizes are taken. Additional options passed with every call of RRDTool, for example --slope-mode to smooth the graphs. The path to the config file for the pages. After reaching this value links to the graphs will be marked as inactive. If PNP is called with a host only index. The title and number of graphs can be specified globally in this place.
Additionally you can influence the timeranges via the URL. This can be useful to automatically create PDF documents. The graph will start one week prior to the current date and time. It will end at the current timestamp. That way - as an example - you can display the traffic rates of all tape libraries. Regular expressions are possible so you can accomplish a lot with only few definitions - provided that you have appropriate names.
Comments start with a hash-sign and are possible within lines as well. The list of host name will only work if you use regex 0! And now some definitions with regular expressions. In some cases you may want to limit the display to just one graph.
PNP provides access to RRD data using the xport controller. The output format can be specified. At the moment the formats xmljson and csv are supported.
You can also use wget to generate images and place them in periodic reports. One example may be:. For details please look at "time ranges". The XML files are created automatically and contain information about the particular host and service.
The header contains information about the plugin and the performance data. PNP templates are PHP files which are included during execution of PNP using the PHP function include. This means that every PHP code in templates will be interpreted so manipulation of all values is possible.
These two arrays are used to call 'rrdtool graph ' so every option is possible that RRDtool supports. All options of RRDtool are described very thoroughly on the RRDtool Homepage.
Inside the templates the data from the related XML files can be used. An area will be drawn using data from the variable var1. The color is defined in HEX notation 00FF00 red, green, blue. The three GPRINT lines build up the caption for the graph.
The current values are formatted using the printf syntax. These values are stored in the XML file associated to the appropriate service. In the first part of the XML file the performance data is stored in separate components.
The XML file contains other information. For the benefit of readability the following lines show only an extract. The various XML fields can be used as variables in the PNP templates. Each field is available as a variable with the same name. There are situations where this behaviour must be overruled, for example when universal commands have been defined.
The following options can be defined in it:. During installation a sample become a binary option signals anyoption broker file with the extension. More datatypes are explained in the RRDTool documentation found at rrdcreate. RRD databases can be created with fixed minimum and maximum values.
You will find further details at http: One or more RRD databases per service. Each datasource will be stored in a separate RRD database.
The data will not be migrated automatically! You will find a conversion script here. More information at http: In most situations, one can easily get desired template names, by using suitable command object definitions. If Nagios is implemented as a distributed system you have to decide where PNP should be installed.

From a technical view this question is not important. PNP can be installed on the slave s as well as on the master server. Or only on the master? Often another check command is used on the master. If PNP finds a string enclosed in brackets at the end of performance data it will be recognized as check command and will be used as PNP stock options ifrs brasil. Nagios documentation related to this topic can be found here.
The command used in the documentation can be adapted easily. This results in some difficulties for PNP which has to extract the information of several plugins from the performance data.
RRDtool has to do very much disk updates but cannot use the disk cache in nagios event_broker_options optimal way. One improvement is made by collecting and sorting the data. It is more effective to write many updates to an RRD database in one block. The disk cache can be the rise of the stock market 1920s more effectively that way.
At this point I'd like to thank Florian octo Forster, Kevin Brintnall and Tobi Oetiker. The development of this daemon has been coordinated exemplary on the rrd-developers mailing list. The rrdcached is working as a daemon in the background and opens a UNIX or TCP socket to wait for requests of rrdtool. Due to security reasons newer versions of rrdcached cannot use absolute paths for network access anymore so the only possible way are unix sockets.
Option -l defines the socket the daemon will listen for update requests. The default TCP port will be Option -z defines a maximum delay which will be used to spread the write cycles over a certain range [0-delay] to avoid parallel write accesses. The value of option -z must not be larger than -w. Option -j defines the path to a journaling directory. All requests will be logged there so that they can be processed after a restart in case the daemon crashes.
Because two components of PNP have to prepared for the use of rrdcached there are changes in two config files. NPCD Nagios-Perfdata-C-Daemon was written to provide an asynchronous mode to handle performance data with nagios. In large nagios installations, your average check latency may increase to a non-acceptable high value. This means that Nagios should do a check at time x but actually does it y seconds later. If you tell the Nagios core that you want to process the performance data after every single check this is doing well for a certain amount of checks but above this limit you will run into latency problems.
This move is a very fast action for the Nagios core and the core will be done with the processing of performance data and can continue to do what it should do: As mentioned above the Nagios process has finished its work with moving the performance data file to a spool directory but this won't bring the data into the RRD files.
For this task you can start npcd to have a look at the defined spool directory and start an action for every file which is found. You have to control NPCD with its own configuration file like the rolled out npcd. If you decide to not rename the config file, it might be overwritten by a future update of PNP. This is the expected format:.

PNP mandatory requires valid performance data of nagios plugins. So what is this performance data? The format is specified within the Developer Guidelines you'll find an excerpt here but should be exemplified here nonetheless: All other values are optional.
If you see graphs without text then this may be the cause. For details please have a look at the documentation of your web-server specific to your distribution. Sourceforge Download Starting with PNP 0.

PNP will now work with lighttpd and php-cgi. Webfrontend based on Kohana. Upgrade to version 0. Summary of a PNP 0. AVERAGE " ; Constants in template files don't work anymore, so that they have to be converted to variables. Installation The installation of PNP will be described in more detail.
Please unpack PNP as user root: The output at the end is important. If they look okay, type 'make all' to compile. If necessary it can be specified using the following syntax: Invoking make all compiles the components like NPCD which are written in C make install copies everything to the right places in the file system. After the installation of the program and HTML files you can copy a sample Apache configuration file to your web-server config directory make install-webconf You can call make install-config optionally.
To install the NPCD Init script call make install-init All these steps are combined in make fullinstall Note: Configuration The configuration of the already mentioned modes of performance data processing will be described in more detail. The directives and their meaning: Data will be defined using Nagios macros.
The perfdata routines can now be used for other addons. Checking the installation If everything went well until now you can try to call PNP using your web browser. Some basic settings should be checked 1. Nagios web frontend Of course PNP should be easily accessible.
You do not want to search long for the right graph. PNP is installed and running. This file must NOT be executable.
pnpdoc_complete [PNP4Nagios Docs]
Otherwise it will be treated as a CGI which will result in an error. Apache ssi and Nagios ssi only have a similar name. Please note that until Nagios 2.
Following the most important parameters: The path to the RRDtool binary. Will be detected by. Timeranges In the overview PNP shows five timeranges which can be defined in config.
Data export PNP provides access to RRD data using the xport controller. One example may be: PNP uses templates to influence the appearance of RRD graphs. Templates are stored at two places in the file system. PNP template must have the following characteristics: The following options can be defined in it: Outgoing from the following example of a Nagios command-definition: This option has effect only during creation of the RRD database.
In a few situations it might be necessary to limit the values which are valid for RRDTool. Possible values are MULTIPLE and SINGLE, respectively. A RRD database per service MULTIPLE: Starting with PNP 0.
Consider the followng example: Which of above two solutions one follows is largely a matter of taste. Distributed Systems If Nagios is implemented as a distributed system you have to decide where PNP should be installed.
Of course this has to correspond with the options of rrdcached! NPCD NPCD Nagios-Perfdata-C-Daemon was written to provide an asynchronous mode to handle performance data with nagios. Performance improvements for Nagios. Just rename it to npcd. These are the essential configuration directives for NPCD: NPCD will rotate the logfile if the filesize of the current log is above this limit.
The command line will be created like this: This is the expected format: Be aware of a limitation in the amount of data that NRPE returns to Nagios. Trailing unfilled semicolons can be dropped.
