shinken 1.2.4 on ubuntu desktop 12.10

26 feb 2013

motivation

need to get shinken-1.2.4 working on ubuntu desktop 12.10 and later i want to run it on a raspberry pi.

shinken installation

in general we follow the installation guide from [1]

BUT first install libmysql-dev or you will hit issue [2][3]:
```
 apt-get install libmysqlclient-dev
 apt-get install python-dev
 apt-get install python-pip
```
note: if you don’t install libmysqlclient-dev the pip installation of MySQL-python==1.2.4b2 will bail out with an error

since the most recent MySQL-python has an issue with distribute, we downgrade it:

 pip install distribute==0.6.28
 pip install MySQL-python==1.2.4b2

note: if you don’t install MySQL-python==1.2.4b2 then the shinken 1.2.4 installer might have a problem

fixing the pnp4nagios from 2.17 to 2.18

bugfix, see [6], for the (2.18 release). if we don’t updated from 2.17 to 2.18 our pnp4nagios will only produce an empty document and thus no RRD graphics.
```
 Bugfix: Blank screen on PHP 5.4 fixed
```
get the source of shinken:
```
 wget http://www.shinken-monitoring.org/pub/shinken-1.2.4.tar.gz
 tar xfz shinken-1.2.4.tar.gz
 cd shinken-1.2.4
```
now change install.d/shinken.conf:
```
 install.d/shinken.conf -> export PNPRELEASE="17" 
```
to
```
 install.d/shinken.conf -> export PNPRELEASE="18" 
```
for more details how i learned about this issue, see [[shinken_1.2.4_on_ubuntu_desktop_12.10/#index1h2]]

execute the installation

 ./install -i
 ./install -p nagios-plugins
 ./install -p check_mem
 ./install -p manubulon
 ./install -p check_netint 
 ./install -a pnp4nagios

and then restart the services

  /etc/init.d/shinken restart
  /etc/init.d/npcd restart

some parts of that script seem to run forever so be patient

 # ./install -i

fix the installation:

many parts of the installation are broken, so for basic operation here are some fixes:

create a common secret key (for pnp4nagios and npcd communication):

  cat /dev/urandom | tr -dc _A-Z-a-z-0-9 | head -c${1:-32} > /usr/local/pnp4nagios/etc/secret.key
  chown shinken:shinken /usr/local/pnp4nagios/etc/secret.key

fix pnp4nagios to use the common key file by looking at /usr/local/pnp4nagios/etc/process_perfdata.cfg: disable KEY = should_be_changed and enable KEY_FILE = /usr/local/pnp4nagios/etc/secret.key (see this example how it should look like):

 ...
 # enables or disables encryption. It is strongly
 # advised to not disable encryption. Anybody will be
 # able to inject packages to your worker.
 # Encryption is enabled by default and you have to
 # explicitly disable it.
 # When using encryption, you will either have to
 # specify a shared password with KEY = ... 
 # Default is 1.
 #
 ENCRYPTION = 1

 # A shared password which will be used for
 # encryption of data pakets. Should be at least 8
 # bytes long. Maximum length is 32 characters.
 #
 #KEY = should_be_changed

 # The shared password will be read from this file.
 # Use either key or keyfile. Only the first 32
 # characters will be used.
 KEY_FILE = /usr/local/pnp4nagios/etc/secret.key

finally, restart the services:

  /etc/init.d/shinken restart
  /etc/init.d/npcd restart

note: cpu/load/memory/NetworkUsage all fail for localhost at my machine but i get ping latency statistics and RRD graphs (it says: Cpu UNKNOWN36m 2s (Service Check Timed Out))

finally, open these two pages in your browser:
- http://localhost:7767
- http://localhost/pnp4nagios
note: it could take 2minutes for pnp4nagios to generate RRD graphics
see the logs:
```
 tail -f  /usr/local/shinken/var/*.log
```
note: in case you want to debug npcd, see [[shinken_1.2.4_on_ubuntu_desktop_12.10/#index1h2]]

since monitoring localhost is not enough:

go to /usr/local/shinken/etc/hosts and add a file like wiki.serverkommune.de.cfg:

 # cat wiki.serverkommune.de.cfg

 define host{
 host_name                      wiki.serverkommune.de
 contact_groups                 admins
 address                        wiki.serverkommune.de
 use                            http
 }

afterwards restart shinken:

 /etc/init.d/shinken restart

security: change the admin user password:

 cd /usr/local/shinken/etc
 htpasswd htpasswd.users admin

hacking shinken

when i select a server which i do monitor, like wiki.serverkommune.de, there is the ‘Graphics’ tab which says:

 Oh snap! No graphs available!

i tried to debug this to no avail!

this string seems to be references from: shinken/webui/plugins/eltdetail/views/eltdetail.tpl

 %uris = app.get_graph_uris(elt, graphstart, graphend)
 ...
 <div class="font-red"><strong>Oh snap!</strong> No graphs available!</div>

so i tried to find references to get_graph_uris:

 shinken/modules/webui_broker/webui_broker.py:    def get_graph_uris(self, elt, graphstart, graphend, source = 'detail'):
 shinken/modules/webui_broker/webui_broker.py:                f = getattr(mod, 'get_graph_uris', None)
 shinken/modules/graphite_ui.py:    def get_graph_uris(self, elt, graphstart, graphend, source = 'detail'):
 shinken/modules/pnp_ui.py:    def get_graph_uris(self, elt, graphstart, graphend, source = 'detail'):

according to the devs this page should work: http://192.168.11.114/pnp4nagios (for me it is an empty page)

because of the fact that there were no graphics i started looking at pnp4nagios and found npcd [Nagios Performance Data C Daemon]:

 /etc/init.d/npcd status
 npcd (pid 994) is running...

a look at the task

 ps aux | grep npcd
 shinken    994  0.0  0.2  90776  1028 ?        S    02:41   0:00 /usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg

i’ve played with various values in the configuration file:

log_level
/usr/local/pnp4nagios/libexec/process_perfdata.pl

but it seems that the npcd service cleares the perfdata_spool_dir = /usr/local/pnp4nagios/var/spool/

the error must be somewhere in there!

a closer look at /usr/local/pnp4nagios/libexec/process_perfdata.pl:

it seems that: /usr/local/pnp4nagios/etc/rra.cfg does not exist
however, /usr/local/pnp4nagios/etc/rra.cfg-sample does
/usr/local/pnp4nagios/etc/secret.key is not there either

/usr/local/pnp4nagios/var/perfdata exists and contains files:

looking at /usr/local/pnp4nagios/etc/process_perfdata.cfg it seems that a password was missing and the secret file wasn’t set either

# enables or disables encryption. It is strongly
# advised to not disable encryption. Anybody will be
# able to inject packages to your worker.
# Encryption is enabled by default and you have to
# explicitly disable it.
# When using encryption, you will either have to

#
ENCRYPTION = 1

# A shared password which will be used for
# encryption of data pakets. Should be at least 8
# bytes long. Maximum length is 32 characters.
#
KEY = should_be_changed

# The shared password will be read from this file.
# Use either key or keyfile. Only the first 32
# characters will be used.
# KEY_FILE = /usr/local/pnp4nagios/etc/secret.key

what about pnp4nagios vhost? apache seems to be running:

/etc/init.d/apache2 status
Apache2 is running (pid 1459).

   (14:33) <   qknight> when i type: http://192.168.11.114/pnp4nagios/graph?host=blog.lastlog.de i get a total empty page (no html source code)
   (14:34) <   qknight> http://blog.lastlog.de/posts/shinken_1.2.4_on_ubuntu_12.10_LTS/
   (14:34) <   qknight> and i don't know where to start debugging the setup
   (14:35) < _pitchfor> pnp4nagios verison?
   (14:35) < _pitchfor> PHP Version?
   (14:38) < _pitchfor> you site points to the old 0.4.x docs
   (14:38) < _pitchfor> qknight:  so which version of pnp4nagios do you use?
   (14:39) <   qknight> _pitchfork_: npcd 0.6.17 - $Revision: 637 $
   (14:40) < _pitchfor> and why do you link to the 0.4.x docs?
   (14:40) < _pitchfor> anyway
   (14:40) < _pitchfor> which PHP version do you use?
   (14:40) <   qknight> pnp4nagios-0.6.17
   (14:41) < _pitchfor> PHP not PNP
   (14:41) < _pitchfor> http://docs.pnp4nagios.org/pnp-0.6/dwnld#changelog
   (14:41) <   qknight> PHP Version => 5.4.6-1ubuntu1.1
   (14:41) < _pitchfor> http://docs.pnp4nagios.org/pnp-0.6/dwnld#changelog
   (14:41) < _pitchfor> fixed with pnp4nagios 0.6.18
   (14:41) < _pitchfor> happy updating ;)
   (14:42) <   qknight> _pitchfork_: what is fixed with that new version?
   (14:42) < _pitchfor> http://docs.pnp4nagios.org/pnp-0.6/dwnld#changelog
   (14:44) <   qknight> _pitchfork_: sorry?
   (14:44) <   qknight> i will try to update now
   (14:44) < _pitchfor> qknight:  -> Bugfix: Blank screen on PHP 5.4 fixed
   (14:44) <   qknight> oh, right
   (14:44) <   qknight> thanks!

finally the fix (very simple one indeed): in the installer of shinken change shinken-1.2.4/install.d/shinken.conf:
```
  install.d/shinken.conf -> export PNPRELEASE="17" # must be updated to 18 instead!
```

note: see bugfix in [6] for the 2.18 release

Bugfix: Blank screen on PHP 5.4 fixed

shinken review

packaging

summary:

i tried third party packages for shinken but it failed horribly (as usually when i do something with third party stuff on ubuntu/debian).
source deployment seems to be a good idea for the time being - until someone packages it for ubuntu

anyway, when being used to nixpkgs this seems to horribly wrong!!1!

usability

this screenshot shows the shinken UI:

but:

the layout (picture above) is not structured in a clean/obvious way, i often need several moments to realise which result belongs to which server
when hoovering the mouse over a latency meassure (as shown in the picture above) it sometimes does weird things when the page is being reset
expanding several hosts makes the lower part of the page unusable as pageresets frequently reset the view to the top
sometimes hoovering does not work so there won’t be any graph
there is no indicator when the data was refreshed the last time, so once i thought everything is alright even though it was not!
when being in a host view i can’t use the ‘Graphs’ tab directly (it would show ‘Oh snap! No graphs available!’) but instead i have to select a service in the ‘Impacts’ tab first. why is this ‘Graphs’ tab there then?!
i could’t get CPU/Load/Memory check for localhost working

i tested all this both with ff and chrome. in general i like shinken and maybe someone benefits from this guide? how knows ;-)

future steps

using NRPE (Nagios Remote Plugin Executor) to monitor remote machines. see [7][8][9]
put shinken behind apache, thus make the service use 80/443, see [10]
consider using thruk, see [11]

summary

i’ve wasted about 3 days debugging shinken for ubuntu desktop 12.10. anyway, i need this setup as i want to run it on a raspberry pi! i like the documentation on the webpage and also the installer and installation steps is quite usable.

i really love the impact graph. can’t wait to see it in our more complex setup here!

consider using Centos/RHEL

hvad@shinken#irc.freenode.net recommended to use Centos/RHEL 6.x by using the EPEL repository. since i want to run shinken on the raspberry pi this is no option right now ;-P

thanks for the help to hvad/Issif/oliv-
