shinken 1.2.4 on ubuntu desktop 12.10

26 feb 2013

copied from shinken-monitoring.org

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]

  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

  2. 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

  3. 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]]

  4. 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

  5. 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))

  6. finally, open these two pages in your browser:

    note: it could take 2minutes for pnp4nagios to generate RRD graphics

  7. 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]]

  8. 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

  9. 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:

    ls -la  /usr/local/pnp4nagios/var/perfdata/serverkommune.de/

  • 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

# 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:

Apache2 is running (pid 1459).

   (14:38) < _pitchfor> you site points to the old 0.4.x docs

   (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

   (14:42) <   qknight> _pitchfork_: what is fixed with that new version?
   (14:42) < _pitchfor> http://docs.pnp4nagios.org/pnp-0.6/dwnld#changelog

   (14:44) <   qknight> 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-
