Icinga Director v1.4.0

 Tue, 10 Oct 2017 17:28:44 +0200 
#^Icinga Director v1.4.0 has been released
We tagged v1.3.2 more than two months ago and according our initial plans it should have been announced together with v1.4.0. However, sometimes things take longer than expected. But now it’s official: Director v1.4.0 is our shiny new release.

Business Process module

 Fri, 27 Jan 2017 18:01:25 +0100 
There is a lot of progress compared to the old BPM.

Business Process module v2.0.0 released
Want to visualize part of your IT infrastructure in a hierarchical way? Do you know the Business Impact of single services? What would happen in case you power down a specific server? Would it have any influence on your most important services? If yes, which applications would have been affected? This is what the Icinga Business Process module has been built for.

Define as many processes nested as deep as you want: each node can calculate it’s own state based on a given logical operator. Show them as a tree or using the tile renderer. Discover the business impact of your components, simulate state changes and deploy Icinga Service Checks and Notifications. Start to monitor whole processes instead of single services.

Director to the rescue

 Tue, 24 Jan 2017 18:29:39 +0100 
Exceptions prove the rule, Director to the rescue
Two and a half month have gone by since version 1.2.0. Yesterday we tagged the latest release: version 1.3.0. As we all know, Director is a fantastic tool for automation, being the glue between your various data sources and your monitoring. But in the rough real world not all the things are always automated. Therefore, this release puts focus on managing all those “little exemptions” many of you are facing in their daily work with in semi-automated environments.

What a nice collection of monitoring plugins! Setting up a Centreon Monitoring system was my final practical task during my apprenticeship. After switching to Icinga some years later, these plugins I unfortunately lost sight of.

“centreon-plugins” is a free and open source project to monitor systems. The project can be used with Centreon and all monitoring softwares compatible with Nagios plugins.

Icinga Director v1.2.0 has been released
Just 4 months have gone by since 1.1.0, and slightly more then 7 months since our first stable release. Icinga Director matured fast and has grown from a small Icinga Web 2 module to a pretty huge project. Yesterday we released version 1.2.0, packed with new features, bug fixes and usability improvements.

Icinga 2 meets InfluxDB

 Fri, 02 Sep 2016 16:58:27 +0200 
Icinga 2 meets InfluxDB
When it comes to monitoring we like to send out a notification as soon as the problem occurs. What’s better than a system that reports a problem the very moment it appears, right? However, we are aware that alerting alone is not always enough. To identify the problem’s root cause it is often necessary to have more information about a service besides its availability state. To meet this claim, most of the monitoring plugins used with Icinga 2 can return performance data. Additionally, the output contains a string showing one or more performance data metrics, for example the time a host or service check took to execute, the number of bytes being transferred, or the free disk space. With the new InfluxDBWriter feature of Icinga 2.5 it’s possible to automatically store this data in an InfluxDB database – without detour. In order to achieve that, the corresponding Icinga 2 object communicates with the native InfluxDB HTTP API.


I really should replace the old RRD perfdata files with InfluxDB. Grafana is a really nice tool.

M$ System Center Operations Manager connector for Icinga 2

icinga2-scom-connector - SCOM Alert connector for Icinga 2
The SCOM connector will help you import alert data from SCOM into Icinga 2.

It helps you to update Icinga's configuration with Hosts monitored by SCOM.

The other part of the tool will query all open alerts from SCOM and publish that status into Icinga, so you can see and get alerted about open problems.

When releasing Icinga 2 in its final version, we got quite a lot of feedback on why there is no agent, and how to monitor remote clients. Back in the beginning of 2014 we already had an idea on how to implement it, but you’d better design, re-design and even re-design such an i...

Creating suitable templates for your performance data in pnp4nagios is really worth the effort. Should have worked with the pnp4nagios templates much earlier! Still so many ideas how to improve it and add more features. Just realized today how long I haven't really worked with our monitoring system anymore. Had to delegate this task some years ago to others, but now I see how much more you could do with it and somehow I regret it.

Always got to hear there is no CPU stats for DELL switches, also the monitoring plugins I saw had fans, temp, psu, ports, etc. but no CPU. So I was bit excited when I found CPU stats in SNMP today for a DELL PowerConnect 2848. But then again in other places the SNMP implementation is just broken. It is the most recent firmware 1.0.0.45 from last year. :-!$ snmpwalk -v2c -c public switchaddress .1.3.6.1.4.1.674.10895.3000.1.2.110.7

Is DELL a company that will fix such problems?

Very impressive statement:
With an empty cache, just four requests are sent from the browser, amounting to a crazy total of 60KB to be loaded by the server. This is the HTML code, a large Icinga logo, Javascript for the application and various style sheets.
From this point on, no single JS or CSS file needs to be loaded.

NSClient++ new configuration

If you need to monitor M$ Windows servers #NSClient++ is a nice tool. Today I had to change some service checks and tried the release candidate from v0.4.2. It is quite different, but it is absolutely worth to dig into the new configuration and possibilities. The new filters and all these things are so powerful and amazing. \o/
