pip install fails

Running docker-compose up in shinken_thruk_graphite returns the following error:

Step 4/35 : RUN useradd --create-home shinken &&                 pip install shinken pymongo>=3.0.3 requests arrow bottle==0.12.8 &&                 update-rc.d -f apache2 remove &&                 update-rc.d -f shinken remove
 ---> Running in fe2e3ade3cf4
ERROR: Service 'shinken' failed to build: The command '/bin/sh -c useradd --create-home shinken &&                 pip install shinken pymongo>=3.0.3 requests arrow bottle==0.12.8 &&                 update-rc.d -f apache2 remove &&                 update-rc.d -f shinken remove' returned a non-zero code: 1

There appears to be some issue with pip:

  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement shinken

The only way I could get this to build was by adding --index-url=https://pypi.python.org/simple/ to the pip install commands and removing the pip arrow package install.

Enabling ConfigTool

Hey,

have you ever tried to enable the config tool, to allow editing the config from thruk frontend?

Currently trying, but struggling with some issues.

Regards,
Dennis.

Temporary unavalaibility of booster-nrpe module from shinken.io

Hi, just to inform that the booster-nrpe module is unavailable at the moment. We are asking to the maintainer to (re)upload it.

Sorry for the inconvenience.

Shinken alwasy redirects to port 80

I have installed the docker image in a Synology NAS. I tried manual and automatic port mapping (set in the docker UI interface of the NAS). I can reach the shinken webui using http://ip:port/user/login, but after inputting credentials and clicking on login, i am redirected to an url without the port and therefor can not reach anything beyond the login page. going directly to http://ip:port/ will also redirect to url without port.

can i edit the configs somewhere to make shinken webui run on a specified port or use an env variable?

Monitoring Windows Machines

In order to monitor windows machines there are some packages missing. The following packages need to be installed in order for the windows pack monitor to work:

libconfig-inifiles-perl
libdatetime-perl
libnumber-format-perl
libscalar-list-utils-perl

And to install the monitoring pack in the appropriate section of Dockerfile:

su - shinken -c 'shinken install windows'

Use smaller base image

Hey,

I was just about to try this out (I still will), and I noticed the use of the debian base image. Would it be possible to utilize a smaller image?

I could foresee a number of issues, such as monitoring using standard utilities (curl, wget, ping, openssl), but I hope it would be kind of simple :).

Mike.

Please update webui to webui2 interface

The webui2 interface is much nicer than webui and it has plenty of features which could help us.

guide for Play with Docker

I made a guide that shows you how to deploy to Play with Docker - https://labs.play-with-docker.com

https://gist.github.com/cornernote/695cc633680df7b5ccfd02ffa6dd5ab0

Thought you may want to include it in your docs somewhere.

Shinken docker SSL handshake issue - Remote host

Hi all,

I have Shinken inside docker container running on a host. Then I have remote hosts where I have NRPE installed. They are not on the same machine. Docker IP address is 172.17.0.27 and then I installed the following packages on the remote host:
apt-get install openssl nagios-nrpe-server nagios-plugins nagios-plugins-basic nagios-plugins-standard
But when I run the check_nrpe command from inside the Shinken docker container, I get the SSL handshake error:

root@containerID:/usr/lib/nagios/plugins# ./check_nrpe -H 10.154.20.52
CHECK_NRPE: Error - Could not complete SSL handshake.

I changed the followings on my remote host is the allowed_hosts:
allowed_hosts=127.0.0.1,172.17.0.27
sudo echo 'dont_blame_nrpe=1' >> /etc/nagios/nrpe_local.cfg
Then rebooted the service: sudo service nagios-nrpe-server restart

Can someone please let me know what I did wrong?

Thanks

How to set up Apache proxy

Hi there!
Everything is working fine except that I'm unable to set up an Apache proxy.
I would like to do so to be able to put a ssl certificate on Shinken webui.
I've tried to change the apache original file or even add virtual host but still having troubles.

Virtualhost looked something like this:

`
ServerName shinken.tld

    ProxyRequests Off
    ProxyPreserveHost On
    ProxyVia On

    <Proxy *>
    Order allow,deny
    Allow from all
    </Proxy>

    ProxyPass / http://shinkenIP:8082/
    ProxyPassReverse / http://shinkenIP:8082/
    RewriteEngine on
    RewriteRule /webui[/]?$ /webui/dashboard/ [R=permanent]

    CustomLog ${APACHE_LOG_DIR}/access_shinken.log combined
    ErrorLog ${APACHE_LOG_DIR}/error_shinken.log

    SSLEngine on
    SSLCertificateFile path/to/certfile
    SSLCertificateKeyFile path/to/keyfile
    ProxyRequests On
    ProxyPreserveHost Off

Any idea ?

How to run individual containers for scaling.?

In this repository I could see that all shinken components have been bundled in to one image..., I have a use case where I need to run individual containers and scale them separately.

Is it possible with this repository ...?

FROM debian:jessie

Would it be possible to have this image deriving from debian:jessie and not debian:wheezy ?

Instructions for setting up webservice

It would be great to enable webservice by default / provide instructions to do so:

https://shinken.readthedocs.io/en/branch-1.4/89_packages/ws_daemon_module.html

Error 404: Not Found on /wall

Hi,

I get Not found: '/wall' when i try to access the webui wall. I'm using basic shinken.

Thanks a lot.

default user/password in README do not work

followed exact instructions to run thrunk/graphite image, and default logins don't work for shinken webui or thruk....
tried admin/admin and passwords listed in htpasswd.users, no luck.

Monitoring remote host with nrpe

Hi,

I don't understand how I can monitor some remote host with nrpe. I have tried many things, but nothing seems to work for me. Note that I'm a beginner on Shinken or Nagios, sorry if the question is basic.

I created a file containing my remote host config in custom_configs/miscellaneous/my-remote-host.cfg :

define host {
    host_name            my-remote-host.com
    use                        generic-host
    alias                      my-remote-host.com
    address                 my-remote-host.com
}

But I don't know how I can define my services to be able to work with nrpe.

I tried something like this (with many variants)

define service {
    use             generic-service
    host_name           my-remote-host.com
    service_description     TEST REMOTE
    check_command            check_nrpe!check_load
}

But I have a not found error. check_nrpe is missing, and after search, it seems to be normal, I should use booster-nrpe instead.

Ok, so, I tried somethings like this :

define module{
     module_name       booster-nrpe
     module_type       nrpe_poller
}

define command {
   command_name   check_nrpe
   command_line  $NAGIOSPLUGINSDIR$/check_nrpe -H $HOSTADRESS$ -c $ARG1$ -a $ARG2$
   module_type    nrpe_poller
}

Source

But I have the same error. (Maybe I don't write these lines at the right location ?)

Am I missing something ?

Thanks.

/var/log or /var/log/shinken should be a docker volume

I think, any logs / data stored should be persisted outside of the docker container, so that when rebuilding no data would be lost (much like custom_config).

sending mail

Hello,

It seems that out of the box it doesn't send emails. I have been fiddling for a while looking for a solution that works and can't seem to find anything.

Are you able to put together an example of how you get it to send email?

I added this to Dockerfile:

FROM rohit01/shinken_thruk_graphite:latest

# Install mail requirements
RUN apt-get update
RUN apt-get install -y ssmtp mailutils

# Cleanup
RUN apt-get clean
RUN rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

Then added to config:

define command {
    command_name    notify-host-by-gmail
    command_line    echo "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\nDate/Time: $LONGDATETIME$" | /usr/bin/mail -s "** Nagios $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **"
}

define command {
    command_name    notify-service-by-gmail
    command_line    echo "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\nDate/Time: $LONGDATETIME$\nAdditional Info: $SERVICEOUTPUT$" | /usr/bin/mail -s "** Nagios $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **"
}

define notificationway {
    notificationway_name            gmail
    service_notification_period     24x7
    host_notification_period        24x7
    service_notification_options    w,u,c,r,f
    host_notification_options       d,u,r,f,s
    service_notification_commands   notify-service-by-gmail
    host_notification_commands      notify-host-by-gmail
    min_business_impact             1
}

define contact {
    use                             generic-contact
    contact_name                    me
    alias                           Me
    email                           [email protected]
    notificationways                gmail
}

I'm not sure how to check what's wrong, but I'm not getting emails.

I get an email if I do this:

docker-compose exec shinken bash
echo "Hello World" | mail -s "Test Email" [email protected]

Dockerfile has issues with check_fping

extra_plugins dir does not contain the check_fping plugin, and fails on this line:

          chmod u+s check_apt restart_service check_ping check_icmp check_fping apt_update

service packs

How would one go about setting up additional services like exchange, dc, windows etc

graphs not available

Hello,

Graphs: http://localhost/service/docker_shinken/http_port_7770#graphs. Available only on shinken_thruk_graphite image.

I can't seem to get this tab. It's just not there.

to reproduce:

goto https://labs.play-with-docker.com/ and start new instance
get shinken_thruk_graphite definition:

curl -Lo docker-compose.yml https://gist.github.com/cornernote/695cc633680df7b5ccfd02ffa6dd5ab0/raw/ab8f36617a636212692cfe4d93b27b5ed873823d/shinken_thruk_graphite.docker-compose.yml

get docker_shinken config:

mkdir configs
curl -Lo configs/docker_shinken.cfg https://gist.github.com/cornernote/695cc633680df7b5ccfd02ffa6dd5ab0/raw/ab8f36617a636212692cfe4d93b27b5ed873823d/docker_shinken.cfg

Start the stack

docker-compose up -d

Now click the port next to the IP address, and you will be taken to the interface, then goto
