How to install Munin scripts for Open-Xchange

Support for Jolokia

By Version 7.4.0, Munin Scripts do support Jolokia as a bridge to get their information. This has been done to get less overhead and speak with the corresponding JMX-beans directly.

Prerequisites

Munin node and munin master must be installed and configured prior using the Munin scripts package for Open-Xchange. The installation for this core components differs on various Linux distributions. For details, please visit:

# enabled=1
# gpgcheck=1
# metadata_expire=0m

and run

$ yum update
$ yum install open-xchange-munin-scripts

open-xchange-munin-scripts-jolokia

Munin-scripts for Jolokia need an additional perl modules json and lwp, which are set inside the depenecies. Those should be installed automaticly.

If not, please install the following modules:

Debian: libwww-perl, libjson-perl

rpm: perl-JSON, perl-libwww-perl

Configuring munin-node scripts for Open-Xchange

The configuration of the scripts is done automatically.

Note: The database pool monitoring script will get only configured if the Open-Xchange server is running and the database pools initialized when installing the open-xchange-munin-scripts package. That can be verified by e.g.:

# showruntimestats -x | grep "DB Pool"
com.openexchange.pooling:name=DB Pool 4,NumWaiting = 0
com.openexchange.pooling:name=DB Pool 4,PoolSize = 3
com.openexchange.pooling:name=DB Pool 4,NumBrokenConnections = 0
com.openexchange.pooling:name=DB Pool 4,NumActive = 0
com.openexchange.pooling:name=DB Pool 4,NumIdle = 3
com.openexchange.pooling:name=DB Pool 4,AvgUseTime = 4.948
com.openexchange.pooling:name=DB Pool 4,MaxUseTime = 16777
com.openexchange.pooling:name=DB Pool 4,MinUseTime = 0

Configuring for open-xchange-munin-scripts-jolokia

Munin Scripts for Jolokia do have some additional settings for jolokia.

vim /etc/munin/plugin-conf.d/ox

Key Default value Comment
env.oxJolokiaUrl http://localhost:8009/monitoring/jolokia Base url for jolokia
env.oxJolokiaUser "changeMe!Now" User used for authentication with HTTP Basic Authentication.
env.oxJolokiaPassword "s3cr3t!toBeChanged" Password used for authentification

WARNING: If env.oxJolokiaUser is not changed from its default value changeMe!Now , monitoring will not work as the user changeMe!Now is set to stop monitoring inside the munin scripts.

Both, env.oxJolokiaUser and env.oxJolokiaPassword need to be set to the same value as set inside jolokia.properties

Configuring for OX Documents / Documentconverter

OX Documents and Documentconverter monitoring can used by installing the additional packages open-xchange-documents-monitoring and open-xchange-documentconverter-jolokia. The Documentconverter uses a different port to access monitoring data. The corresponding oxJolokiaURL is has to be configured with an entry in the settings.

[ox_documentconverter*]
env.oxJolokiaUrl http://localhost:8008/monitoring/jolokia

See this article for more details.

Supplementary notes for distributed munin clients

Munin node

The default munin node configuration only allows connections from localhost, which means that munin master has to run on the same host. If there already is a munin master running, that master IP has to be added to the file /etc/munin/munin-node.conf on each node:

# A list of addresses that are allowed to connect.  This must be a
# regular expression, since Net::Server does not understand CIDR-style
# network notation unless the perl module Net::CIDR is installed.  You
# may repeat the allow line as many times as you'd like

allow ^127\.0\.0\.1$

Munin master

Make sure the munin and apache packages are installed. If only localhost is going to be monitored, the default configuration is sufficient. Other munin nodes can be added in the /etc/munin/munin.conf file:

# a simple host tree
[localhost.localdomain]
    address 127.0.0.1
    use_node_name yes

By default, the munin monitoring web page is only reached from localhost, other hosts or networks can be added in /etc/apache2/conf.d/munin:

Allow from localhost 127.0.0.0/8 ::1    # the default setting
Allow from 10.99.0.0/8                  # added network

The munin webpage is located at http://yourhost_where_munin_is_running.org/munin.
