A script to gather valuable data for providing to support engineer
This script is mostly intended as tool for support engineers. If a user reports a problem, the output of the scripts should cover the most common questions a support engineer will have.
The intention is not to collect as much data as possible but collect what is helpful in most cases and providing an overview whithout drowning support in too much data.
Please note: Even though this script is meant to just collect really useful data, it does still collect a lot. Browse through any output before you send it so that you don't send any confidential data without noticing.
Please note as well: The main intention of the script is to provide data when asked for it. While it might be helpful when working with commercial support, sending unwanted big blobs of data into community channels might lower your chances of getting help. Always try the troubleshooting section of the Icinga 2 documentation before requesting any community help. The upcoming "suggestion mode" of this script might help with troubleshooting as well.
Later versions might include options to collect this "usually helpful" set of data or lots of data for deep diving (e.g. whole logfiles, etc.)
This script has several different modes:
- Default mode: Give a quick overview over your setup for professional or community support
- Tarball mode: Create a tarball of the configuration of your setup for thorough investigation by professional support
- Suggestion mode: Search things to improve and possible problems and give advice (still to be implemented)
If your setup consists of multiple hosts you can run on it on every node to get a more thorough overview. If you have e.g. dedicated nodes for graphing the script will work and only analyse the tools you installed on the node. (Although details about Graphers are still missing)
Just use the script without any parameter.
Just run the script with the
# ./icinga-diagnostics.sh -t
Be aware that this collects your whole configuration including passwords, etc. Think before you send this to someone!
The script will thell you where you can find your tarball when it's finished. You can still remove data from the tarball before sending it to someone.
- -z : Calculate zones with their endpoints (very time consuming on large setups)
- -g : add
gdb Output is only useful for debugging problems in the Icinga 2 binary, not for configuration problems. For
gdb to work you have to install
gdb and the "degbugging symbols" for all the programs you want to have their information added. e.g. for Icinga 2 the corresponding package is
icinga2-debuginfo on RedHat/CentOS or
icinga2-dbg on Debian or Ubuntu. In addition you will need the
icinga-gdb file containing the
gdb commands in the directory where icinga2-diagnostics resides.
Currently supported systems
The script currently works on the following operating systems:
- RHEL/CentOS/Oracle Linux/Scientific Linux
- SLES (thanks, wnieder)
- FreeBSD (thanks, @larsengels)
- Debian (still some functionality is missing)
The script currently works with the following software components:
- Icinga 2
- Icinga Web 2
Planned supported systems
The script should work on all Operating systems supported by Icinga 2
The script should gather informations about the most common addons to Icinga 2 and collect data relevant to monitoring setups.
This is an abrreviated output from a run on a Icinga 2 Vagrant box
