Another problem seen in Google Chrome is that the function "onload()" does not get called as it supposed to according to w3c-manual.Files needed to run the demoindex.svgSVG file which show the graphical map and include the javascript file.load-status-nagios-json.js.Javascript which calls the PHP script to get a fresh set of JSON data.status.nagios.json.php (source).PHP script which parses the local /var/lib/nagios,icinga/status.dat and convert it to JSON data format.status.datIt is a file generated by Nagios/Icinga.The first 3 files above could be stored in one single .php if that is more convenient.It is also possible to cache the data and only send the difference by changing the .php script and set a cookie.
Open /etc/nagios/objects/hadoop-services.cfg with a text editor. This file contains service definitions for the following services: Ganglia, HBase (Master and Region), ZooKeeper, Hive, Templeton, and Oozie. perl nagios status.dat *Download File* https://t.co/wyCkJo8nfX Login using the Nagios admin username (nagiosadmin) and password (see Set the Nagios Admin Password). Click on hosts to check that all hosts in the cluster are listed. Click on services to check that all of the Hadoop services are listed for each host. When your action_url contains /pnp4nagios/, there will be automaticallya graph displayed for your host and service. This gives you a quickview about the performance history. The image is then linked toPNP4Nagios to get detailed information. The images speak for themselves, parsing the status.dat for everyrequest takes time and increases linear with the amount of services.Requesting only the needed data for the specific page via livestatushas a much lower overhead and is therefor much faster, but stillincreases linear with the amount of services of course. Just at a muchlower rate. The biggest performance issues for the status.dat based CGIs is onpages where no or nearly no data is needed, like the process info pageor the commands page. The repsonse time for Thruk stays nearlyconstant where Nagios or Icinga still need to parse the holestatus.dat. Livestatus provides instant access to nagios status via a local or tcp socket and introduces almost zero additional CPU load on your monitoring server (but does have a memory footprint, of course). Simple integration with xinetd/unixcat allows it to be queried via the network. Output is in one of three formats: CSV, JSON and Python. Numerous configuration options are available, and it is stable enough for Production usage. The documentation is very good. Additionally, livestatus enables other nagios add-ons, such as "MK Multisite", which aggregates the results from multiple nagios installations into a single GUI without the use of NSCA or passive service checks results, which require nagios configurations to be maintained on both worker and master servers. Django Function:def getNagiosHostStatus(): nagiospass = 'you-forgot-about-dre-1999' nagiosuser = 'apicall' from requests.auth import HTTPDigestAuth try: r = requests.get(' -bin/status2json.py', auth=HTTPDigestAuth(nagiosuser,nagiospass)) data = r.json() except: data = None return(data) Nagvis is an Addon for nagios that allow create our own maps with the nagios information services. The classical method to collect services data from Nagios is reading the file status.dat, this file is updated every 10 seconds by default Icinga 1.x writes object configuration data and status data in a cyclicinterval to its objects.cache and status.dat files. Icinga 2 providesthe StatusDataWriter object which dumps all configuration objects andstatus updates in a regular interval. The Configuration page can to be used to properly configure the Nagios Main Configuration file to enable performance data handling. This should be already set up by the GroundWork installer. But these are the crucial configuration parameters. The image (select Show/Hide) shows the parameters in the Nagios Main Configuration screen that enable performance data handling. Use the following steps to ensure that the performance handler is working as expected. The performance handler log file is /usr/local/groundwork/nagios/var/log/process_service_perfdata_file.log, as configured in the perfdata.properties file. At a high debug_level setting, the following information is entered in the log for each plugin execution: This is the file that Nagios uses to store the current status, comment, and downtime information. This file is used by the CGIs so that current monitoring status can be reported via a web interface. The CGIs must have read access to this file in order to function properly. This file is deleted every time Nagios stops and recreated when it starts. This option deterines what data Nagios will send to api.nagios.org when it checks for updates. By default, Nagios will send information on the current version of Nagios you have installed, as well as an indicator as to whether this was a new installation or not. Nagios Enterprises uses this data to determine the number of users running specific version of Nagios. Enable this option if you do not wish for this information to be sent. La forma clásica de acceder a la informacion actual de sus hosts y servicios es mediante la lectura y análisis del archivo status.dat, que es creado por Nagios en una base regular. El intervalo de actualización se configura a través status_update_interval en nagios.cfg. Un valor típico es de 10 segundos. Si la instalación es cada vez más grande, usted podría tener que aumentar este valor con el fin de reducir al mínimo el uso de CPU y de E / S de disco. La interfaz web de Nagios utiliza status.dat para mostrar sus datos. Analizar status.dat no es muy popular entre los desarrolladores de addons. Así que muchos utilizan otro enfoque: NDO. Este es un módulo de ORC que se carga directamente en el proceso de Nagios y envía todas las actualizaciones de estado a través de un socket UNIX a un proceso de ayuda. Eso crea sentencias SQL y actualizaciones de varias tablas en una base de datos MySQL o PostgreSQL. Este enfoque tiene varias ventajas sobre status.dat: Using your preferred text editor, open the Nagios commands configuration file, located at /etc/nagios4/objects/commands.cfg. Identify the command definitions for notify-host-by-email and notify-service-by-email. For each, verify that the location of the mail binary is /usr/bin/mail, as in the following example: Open the Nagios contacts.cfg configuration file, located at /etc/nagios4/objects/contacts.cfg. Identify the nagiosadmin contact definition. In the email field, enter the email address where you would like to receive Nagios notifications. This tutorial was tested using Nagios Core 4.3.4 on Debian 9.2if(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'howtoforge_com-box-3','ezslot_9',106,'0','0']);__ez_fad_position('div-gpt-ad-howtoforge_com-box-3-0');Even though Nagios Exchange has thousands of available plugins to freely download, sometimes the status needed to be checked is very specific for your scenario.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'howtoforge_com-medrectangle-3','ezslot_8',121,'0','0']);__ez_fad_position('div-gpt-ad-howtoforge_com-medrectangle-3-0');ConsiderationsIt is assumed that: - You have Nagios installed and running (You can follow this Tutorial if not). - You know the basics on Nagios administration. Nagios server in this example is hosted on 192.168.0.150 and an example client is hosted on IP 192.168.0.200Exit CodesTo identify the status of a monitored service, Nagios runs a check plugin on it. Nagios can tell what the status of the service is by reading the exit code of the check.Nagios understands the following exit codes:(adsbygoogle=window.adsbygoogle[]).push(); - 0 - Service is OK. - 1 - Service has a WARNING. - 2 - Service is in a CRITICAL status. - 3 - Service status is UNKNOWN. A program can be written in any language to work as a Nagios check plugin. Based on the condition checked, the plugin can make Nagios aware of a malfunctioning service.Example PluginI will use a simple example. I wrote a plugin in a bash script to check for current Warnings. Let's consider I have the Nagios server configured to alert only on critical status, so I want an alert if I have too many services on a Warning status.Consider the following script (check_warnings.sh):#!/bin/bashcountWarnings=$(/usr/local/nagios/bin/nagiostats grep "Ok/Warn/Unk/Crit:" sed 's/[[:space:]]//g' cut -d"/" -f5)if (($countWarnings eebf2c3492 -- You received this message because you are subscribed to the Google Groups "ESLint" group.
