Introduction

The Checkmk GUI can be customized easily by each user to fit their personal needs. Here are some examples:

• The start page
• The number of columns
• The row limit
• The Sidebar snapins
• The time format

How to set Defaults?

It might be useful to define your own defaults for some of these settings so a new user doesn't have to change everything on his own.

...

1. Get the factory defaults from the original file, for example:

   Code Block
   language bash theme RDark title ~/lib/python3/cmk/gui/plugins/config/base.py
   # Default timestamp format to be used in multisite default_ts_format = 'mixed'

   .

2. Create a file below ~/local/share/check_mk/web/plugins/config and define your preferred default setting, for example:

   Code Block
   language bash theme RDark title ~/local/share/check_mk/web/plugins/config/my_base.py
   # We prefer to se both, the absolute and the relative time default_ts_format = 'both'

   .

3. After doing an "omd restart apache", you will find this setting in your GUI:

   Code Block
   language bash theme RDark
   OMD[mysite]:~$ omd restart apache

Example 2: Default Sidebar Snapins

In the case of the sidebar snapins, the file ~/lib/python3/cmk/gui/plugins/config/base.py doesn't help us because the variable "sidebar" that is set there seems to have a new data structure. You can find out this structure by explicitly configuring your sidebar in the GUI and then checking out the file ~/var/check_mk/web/<your_username>/sidebar.mk. The structure you find there can be used in ~/local/share/check_mk/web/plugins/config/my_base.py:

# Newly create users should get these sidebar snapins:
sidebar = [
        {
            'snapin_type_id': 'tactical_overview',
            'visibility': 'open'
        },
        {
            'snapin_type_id': 'bookmarks',
            'visibility': 'open'
        },
        {
            'snapin_type_id': 'views',
            'visibility': 'closed'
        },
        {
            'snapin_type_id': 'search',
            'visibility': 'closed'
        },
        {
            'snapin_type_id': 'time',
            'visibility': 'closed'
        }
    ]

Recommendations

Sometimes it's hard to work out the possible values of a setting. In that case, applying the setting in the GUI and then doing a "grep" in ~/var/check_mk/web might be helpful:

OMD[mysite]:~$ grep -r ts_format ~/var/check_mk/web/
/omd/sites/mysite/var/check_mk/web/cmkadmin/viewoptions.mk:{'svcproblems': {'ts_date': '%Y-%m-%d', 'ts_format': 'abs'}}
