If you get “No such user ” then you should edit /etc/check_mk/multisite.mk and add your username to the admin_users statement. Either you've entered an invalid password or the authenticationconfiguration of your check_mk web pages is incorrect. it will scan localhost for tcp, that is defined in your main.mk configuration file. Thank you in advance. Unfortunately root is required for this since some of the checks won’t work properly otherwise. For commands.cfg make sure you check the notify-host-by-email and notify-service-by-email commands. root@z:~> tar zxf !$:t History. Total Errors: 0, Things look okay - No serious problems were detected during the pre-flight check. So to get it up and running: install nagios, define your contacts (email addresses), define your services (ntp, dns, www, mail, …), define your servers (including printers, switches and whatnot), install the plugins on all servers and/or SNMP including some firewalling/tunneling to get the data to your monitoring machine … yeesh, is this getting tiresome yet? Is there anything near this for check_mk plugin? One little issue I ran into a while ago is documented here in my notes. While you’re at it, make sure in the left pane under ‘Master Control‘ that ‘Performance Data‘ is enabled. address 127.0.0.1 Gah. Install the extension in your Check_MK instance by uploading the mkp package directly via the web interface Add the AlarmManager as a new host, select "No agent" under the Check_MK Agent option in the Data sources section and configure the SNMP settings of the AlarmManager under the SNMP option. Checkmk originated in 2008 as an Agent-substituting shell script for Inetd, and was published in April 2009 under GPL.

Then click the Integrations tab and click Add a new integration. Before you continue, make sure the ssh setup works. Does this integration avaoid that, and (this might be a noob question but,) which Nagios are you deploying here? Next we let check_mk do an inventory of your hosts: # Since the makefile is retarded we have to fake our httpd/extra dir ServerAdmin webmaster@nagios.jemoeder.nl or when everything is ok it says something like: Your environment passed all requirements.

Based on the condition checked, the plugin can make Nagios aware of a malfunctioning service. I have a fully functional setup of nagios and pnp4nagios. Require valid-user The reason for this is that the legacy_checks refer to commands that are manually defined in the Nagios configuration and which are consequently not available to the CMC. If you’re running the older version of check_mk (below 1.1.7i5) you need a different syntax: # Load Livestatus Module I have about 3000 hosts and 40,000 services configured in XI and about 60 hosts configured in check_mk WATO and about 1000 services.

Nagios plugins provide the check_http plugin script. to put its own garbage in later. We need at least version 0.6 for check_mk to work with it.

In lieu of these you can use the more modern custom_checks.These can be conveniently managed in WATO with the Active Checks ⇒ Classical Active and Passive Monitoring Checks rule (also without the CMC by the way).

So for the heck of testing our configuration, I define a host. Let’s see if Nagios agrees with our garbage: This document is intended for use by Nagios administrators looking to integrate SNMP traps into their monitoring configuration to gain greater insight into their IT infrastructure. sleep 1 It requires graphviz though, I couldn’t be bothered.

Haven’t had your problem with the active checks though, the way it’s supposed to work CheckMK does all the checking and reports back to nagios as a passive check. In my nagios logs I see something like: root@z:~/nagios-3.2.2> mkdir -p pkg/usr/share/nagios/cgi-bin root@z:~> tar zxf !$:t A customer is trying to get alarms from DC-RUM to Nagios or Check_MK consoles They are trying to use SNMP for this, but are open to any suggestions if we have other ideas.

A better solution might be to use your existing htpasswd file from your Nagios installation. It adopts a completely new approach of retrieving data from hosts and network components which is very performant and easy to configure - especially in large monitoring environments.
