Color Blind theme for Icinga Web 2

Color Blind theme for Icinga Web 2

Give your Icinga Web 2 a new look – with official ‘Color Blind Theme’ introduced in version 2.7.0! Not just for people with impaired colour vision – with a fresh and well rounded new palette, the new theme is a real looker!

It’s important for us that everyone has the chance to use our tools with maximum effectiveness.We took an existing module from our Icinga Partner Sol1icingaweb2-theme-colourblind by Andrew Foster – refined it a little and it is now part of the default Icinga Web 2 colour scheme bundle!

 

What’s with the change?

The colorblind theme by Sol1 was already very well made, but we saw some minor issues with the chosen colours in terms of:

  • context with the icinga states
  • readability

Well, let’s just have a look first:

So in the top, there is the default Icinga colour scheme – with mocks of the three types of colour deficiency we focused on during the development for the module.

Last row is the new theme which is integrated into the Icinga Web 2 core now.

Icinga state context

Another minor detail to improve was the colour of the WARNING (handled) state, which didn’t really fit in with the rest:

Comparison of colours for the states + handled states

The WARNING (handled) grey sticks out and is hard to connect to the unhandled state colour

So in order to both have the context in which the colours are used preserved and have some sort of hierarchy in severeness of the states some changes needed to be made.

This warranted for a change both in brightness and hue for the OK green as well, so it could be distinguished from the WARNING (handled) yellow:

Readability

There have also been some changes to the font colour:
Handled states (Including OK for urgencies sake) are now displayed with black text.

This makes it a lot easier to distinguish between handled and unhandled states in the blink of an eye.

In case you want to build your own theme, there is a helpful article on the topic from our Partner Würth Phoenix. If you have any issues, feedback or inspiration – please tell us about it here or open an issue on github.

And by the way, I will be speaking about this topic at the Icinga Camp Stockholm as well!

Icinga Cube 1.1.0 is out!

Icinga Cube 1.1.0 is out!

As a little introduction for everyone who has not heard about the cube yet:

The cube module is there to show statistics grouped by the custom variables that have been set for the hosts and services. They are then displayed in up to three dimensions for a quick overview to show the relations.

The services are going cubin’!

The most prominent change is the addition of services:
While it used to be only possible to have the hosts in a cube, the module has now been extended to provide full functionality with services as well.

You can easily switch between hosts and services, while we keep the filters of your cube in place!

  • Support Services #37

 

No more SQL dump crashes! (or at least fewer)

PostgreSQL rollup syntax errors are now smoothed out and will work as intended – also including the documentation for the requirements.
Having custom variables names like SQL keywords also no longer break the cube!

  • Fix SQL keywords breaking the queries #38
  • Fix rollup syntax for PostgreSQL databases #29 + #24

 

Restrictions are in place

Adds a filter that considers protected custom variables.
The cube now polls the restrictions set in the monitoring module and only shows the hosts that the user has permission to view.

  • Apply monitoring restrictions #33
  • Respect protected custom vars #25

 

And just a pinch of UX

Removed the possibility to add more than three dimensions to the cube – we live in a three dimensional world after all.
When the name of a cube tile is too long to fit, it will no longer push everything else downwards but be shortened with an ellipsis instead!

  • Limit to 3 dimensions #36
  • Truncate long headers #35

 

Fixed pröblems with ümlauts

The URL encoding has been adapted so that both white spaces and umlauts are now supported!
Name your vars however you like!

  • Fix Slices with whitespace or umlaut in data field #17

 

 

Icinga Reporting – Hands On

Icinga Reporting – Hands On

After our initial release of Icinga Reporting for early adopters we continued our development and are happy to release v0.9.1 today. The release includes bug fixes and some minor enhancements for the usability. I want to take this opportunity to write a post aimed at the people who are new to the whole reporting shabang – like me 🙂

This week I set out to figuring out for myself why one would need to use reporting and how to get there – and to share my new knowledge with you!

 

What is reporting?

When I’m talking about reporting in this context I mean Business Reporting. I’ll give you a brief overview by citing good old wikipedia:

Business reporting or enterprise reporting refers to both “the public reporting of operating and financial data by a business enterprise,” and “the regular provision of information to decision-makers within an organization to support them in their work.”

 

Wikipedia ‘Business Reporting’ (12.06.2019)

In short: Reporting means collecting data, from a certain period of time.

 

What does Icinga Reporting do?

In simple terms you could say, that the reporting module takes the data from the Icinga Database (IDO) or other modules and displays it. So you gain a nice overview directly in Icinga Web 2 and if you schedule the reports you can also get them per mail or export it to PDF, JSON or CSV format.

You can review the uptime of your hosts and services in the form of a recap of your chosen time period. This gives you the opportunity to improve the accessibility of your systems and environments in the long run. If you want a more in depth description I can point you to this article about the new reporting release.

 

Installation

The process of the installation is already described in the docs here, but for the sake of completeness I’ll do a quick walk through with you here as well.

I documented my way from my installation to my first report for you, installing both the reporting and the idoreporting modules:

 

Step 1: Cloning the reporting repository

You’ll want to navigate into the icingaweb2/modules repository and clone this repository under the name ‘reporting‘.

git clone git@github.com:Icinga/icingaweb2-module-reporting.git reporting

 

Cloning reporting in the modules directory

 

Step 2: Database creation

You will need to create a MySQL/MariaDB database – in this example it will be called ‘reporting‘ for convenience.

Create the db with:

CREATE DATABASE reporting;
GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE ON reporting.* TO reporting@localhost IDENTIFIED BY 'secret';

Then import the schema provided under etc/schema:

mysql -p -u root reporting < schema/mysql.sql

Database creation in MySql

 

Step 3: Activate the module in Icinga Web 2

Log in with a privileged user in Icinga Web 2 and enable the module in Configuration/Modules. Alternatively you can use the icingacli and run icingacli module enable reporting

Activating the module under Configuration/Modules

 

Step 4: Adding the resource

Once you’ve set up the database, create a new Icinga Web 2 resource for it using the Configuration/Application/Resources menu. Make sure that you set the character set to utf8mb4.

Adding the resource under Configuration/Application/Resources

 

Step 5: Cloning the IDO reports repository

Like in step one, just that this time we will clone this repository under the name ‘idoreports’.

git clone git@github.com:Icinga/icingaweb2-module-idoreports.git idoreports

 

Step 6: Import schemas

This step is an analogy to step 2: Import the following schemas also found under etc/schema to your Icinga 2 database (IDO):

mysql -p -u icinga2 icinga2 < schema/slaperiods.sql
mysql -p -u icinga2 icinga2 < schema/get_sla_ok_percent.sql

 

Step 7: Activate IDO reports

Log in with a privileged user in Icinga Web 2 and enable the module in Configuration/Modules/idoreports. Alternatively you can use the icingacli and run icingacli module enable idoreports

 

Configuring a new Report

So you should now be at the point where you can start creating your first reports. Just navigate to the Reporting menu item and you should see a button reading ‘Add report‘.

Creating a new report

You can define exactly what you want to see with the Filter, that you can use just like anywhere else in Icinga Web 2 to see only what is relevant to you.

Break it down by days, weeks or months to see what happened when.

Add your own threshold to set what value must be undershot before the tile will be coloured in an alarming red, so it sticks out for you to immediately see problematic entities.

Finished report

 

Scheduler Daemon

In case you want to have a report sent out to you on a regular basis, you can use the scheduler daemon for that:

icingacli reporting schedule run

This command schedules the execution of all applicable reports. You may configure this command as systemd service. Just copy the example service definition from config/systemd/icinga-reporting.service to /etc/systemd/system/icinga-reporting.service and enable it afterwards:

systemctl enable icinga-reporting.service

You have everything in your hands now to get started with Icinga Reporting. For any questions please feel free to get in touch with us and our lovely community on community.icinga.com. We would love to hear some stories how you use reporting in your organization and how we can help you with your daily work!
