nagios-nsca

The purpose of this add-on is to allow the execution of NetSaint and Nagios plug-ins on a remote host in a manner that is as transparent as possible. This is the server part including the daemon without the client program.

nagios-nsca-client

The purpose of this add-on is to allow the execution of NetSaint and Nagios plug-ins on a remote host in a manner that is as transparent as possible. This package includes only the client program.

pnp4nagios

PNP is a tool that produces graphs from performance data from Nagios plugins.

nagios-plugins-rsync

Checks rsync servers availability, as well as (optionally) individual modules availability. It also supports authentication on modules.

nagios-nrpe

This daemon can be used to run nagios plug-ins on a remote machine for executing local checks. This package contains the software for both client and server.

nagios-nrpe-client

This package contains the Nagios Remote Plug-ins Executor (NRPE) which can execute predefined commands on the remote host. Upon receiving a plugin request from an authorized host, it will execute the command line associated with the command name it received and send the program output and return code back to the check_nrpe plugin. Allowed monitoring commands are described in the daemon configuration file.

nagios-nrpe-doc

This package contains the README files, OpenOffice and PDF documentation for the remote plugin executor (NRPE) for nagios

nagios-plugins-gwfl

The GWFL Nagios Plugins introduced more advanced monitoring, with better data consolidation, meaning less performance and administration overhead. Also, the structure of the plugins meant anyone with a little C knowledge could easily write more plugins using the SNMPGET function included in the GWFL plugins, and using a similar coding format to the plugins provided.

SNMP GETNEXT functionality is included, so that number of CPUs/PSUs/Drives need not be specified, the plugins will determine this themselves.

nagios-nrpe-server
This package contains the plug-in for the host runing the Nagios daemon. It is used to contact the NRPE process on remote hosts. The plugin requests that a plugin be executed on the remote host and wait for the NRPE process to execute the plugin and return the result.
The plugin then uses the output and return code from the plugin execution on the remote host for its own output and return code.

nagios-plugins-printer
This Nagios plugin queries prtAlertTable from the Printer MIB. It honors only prtAlertTrainingLevel = trained(4) or fieldService(5),prtAlertTrainingLevel = other(1),unknown(2),untrained(3) and management(6) are ignored.

For prtAlertSeverityLevel = warning(4) the plugin result is “WARNING”, for critical(3) the plugin result is “CRITICAL”, obviously, for warningBinaryChangeEvent(5) (new in RFC3805) the state is by default “WARNING”, but there is a hardcoded table of change events, which result in state “CRITICAL”

nagios-plugins-zypper

This plugin checks for software updates on systems that use package management systems based on the zypper command found in openSUSE. It checks for security, recommended and optional patches and also for optional package updates.

You can define the status by patch category. Use a commata to list more than one category to a state. If you like to know the names of available patches and packages, use the “-v” option

nagios-plugins-nis

Nagios plugin (script) to check the status of a NIS server on a specified host and NIS domain by asking NIS server for “passwd.byname”. As an additional check, a username may be specified which will then be “looked up” on the NIS server, note that this is optional and only introduced in v1.1

iftop can also run in promiscous mode and listen for all traffic on the subnet and can also listen for traffic on specified networks. iftop can be run in custom modes like disabling DNS name lookups, converting ports to service names, displaying results in Bytes etc.

For a detailed list of options run iftop with a “-h” arguement as follows:

opensuse11:~ # iftop -h
iftop: display bandwidth usage on an interface by host

Synopsis: iftop -h | [-npbBP] [-i interface] [-f filter code] [-N net/mask]

-h                  display this message
-n                  don’t do hostname lookups
-N                  don’t convert port numbers to services
-p                  run in promiscuous mode (show traffic between other
hosts on the same network segment)
-b                  don’t display a bar graph of traffic
-B                  Display bandwidth in bytes
-i interface        listen on named interface
-f filter code      use filter code to select packets to count
(default: none, but only IP packets are counted)
-F net/mask         show traffic flows in/out of network
-P                  show ports as well as hosts
-m limit            sets the upper limit for the bandwidth scale
-c config file      specifies an alternative configuration file

iftop, version 0.17
copyright (c) 2002 Paul Warren <pdw@ex-parrot.com> and contributors

Install IFTOP in openSUSE

Click from the 1-click installer for your openSUSE build to download the YMP file and launch an autmatic installation process which should add the required repositories and download and install the required packages and dependencies.

openSUSE 11.1

openSUSE 11.0

openSUSE 10.3

There are also IFTOP 1-click installers for

SLES/SLED 10

SLES 9

Once the installation finishes succesfully, iftop should be installed under /usr/sbin

opensuse11:~ # which iftop
/usr/sbin/iftop

To have a quick preview of the bandwidth utilization, simply run “iftop” without any arguements:

opensuse11:~ # iftop

To run in a promiscous mode and listen for all traffic on the subnet, run with “-p” option

opensuse11:~ # iftop -p

As shown earlier, use “-h” arguement for all options.

Reporting Options include SLA, Alert, notification and trending reports (using cacti & RRD-based integration addons)

Easily Extendable Architecture with over 200 community addons already available to enhance Nagios

Failover capabilities with distributed monitoring support

Our mission here is to get up and running with Nagios in less than 5 mminutes in openSUSE. So, let’s get on with it. We assume here that the Apache2 webserver is already installed on your openSUSE.

Install Nagios in openSUSE

Based on your version of openSUSE, click the following 1-click installs to install Nagios Core application, Nagios Plugins and Nagios Plugins extras (install in the same order)

|                                     | Nagios |                             | Nagios Plugins|             | Nagios Addons Extras |

openSUSE 11.1

openSUSE 11.0

openSUSE 10.3

This should download the YMP file and automatically launch the YaST package manager to add the required Repositories, download and install Nagios, plugins and the extras and the required dependencies.

Upon completion of the installation, the following are the key locations where the Nagios application and the relevant files will be installed.

Nagiois config files

/etc/nagios

Nagios plugins and cgi’s

/usr/local/nagios

Nagios web interface

/usr/share/nagios

Apache config file

/etc/apache2/conf.d/nagios.conf

Users

The installation also creates the user account nagios and the groups nagios & nagcmd

Create an Admin user for nagios

opensuse11:~ # htpasswd2 -c /etc/nagios/htpasswd.users nagiosadmin

This creates a new htpasswd.user file (-c option) and installs nagiosadmin as a new user for nagios web interface. Any later user account should be added without the “-c” option as follows to avoid the risk of overwriting the htpasswd.users file

opensuse11:~ # htpasswd2 /etc/nagios/htpasswd.users nagiosuser

Thats the web interface sorted.

Make Nagios Start at system startup

Add Nagios to the list of services on the system and make it start automatically at the system start/restart as follows:

opensuse11:~ # chkconfig nagios

opensuse11:~ # chkconfig nagios on

We are nearly there to get Nagios up and running.

Restart Apache

Restart Apache2 webserver to enable the Nagios web interface

opensuse11:~ # rcapache2 restart

Start Nagios

The installation adds a configuration file for the localhost as /etc/nagios/objects/localhost.cfg. This checks the network status, system load, system users, HTTP, PING, Root partition, SSH, Swap and total processes running on the system. This gives us a quick look into Nagios before we go on and add additional systems and services.

opensuse11:~ # rcnagios start

Thats the installation complete. Open a web browser and browse to http://localhost/nagios or http://<IP Address>/nagios if browsing from another system on the network. (Make sure the firewall allows HTTP & HTTPS connections into this system). Enter the username and password for the admin user (nagiosadmin).

Thats it…Nagios is up and running. Now, you can add more devices like more Linux systems and servers, Windows or network appliances. Obviously,monitoring  needs could change from anything being a dead or alive (ping) test to more checks like the ones we do here on the localhost.

A quick tip would be to create seperate config files for different types of devices like Windows, Linux etc or even a config file for each of the devices. This approach of config files for each device can reduce the maintenance perspective as you can pin point issues (if any) down to the particular file for the particular device also, any changes we know is for sure going to be only on the relevant file. The downside would be maintaing the files themselves.

Also, for each of these config files. there needs to be an entry in the /etc/nagios/nagios.cfg file. For instance, the localhost config file is entered as

cfg_file=/etc/nagios/objects/localhost.cfg

Else the cfg file will be completely ignored. Also, a good practice would be to verifiy the config changes (including adding or deleteing new devices) as failing to do so can bring down Nagios completely. To verify simply run nagios with “-v” switch and the config file as follows:

opensuse11:~ # nagios -v /etc/nagios/nagios.cfg

This should report any errors. When all looks good, restart nagios as follows

opensuse11:~ # rcnagios nagios restart

ntop shows the current network usage and displays list of hosts currently on the network and report IP and Fibre Channel (FC) traffic generated by the host. ntop supports TCP/UDP (HTTP/FTP,DNS,Telnet,SMTP etc),ICMP, ARP & RARP,IP/IPX,DLC, Decnet, Apple Talk, Netbios, FC (Control Traffic – SW2, GS3,ELS & SCSI)

Install ntop on openSUSE

To install ntop on openSUSE, click on one of the following 1-click installers based on the version of openSUSE operating system.

openSUSE 11.1

openSUSE 11.0

openSUSE 10.3

This should launch YaST package manager and add requried repositories, install the required package and dependencies for ntop. Accept the defaults and follow the onscreen instructions to complete the installation. Once the installation is successfully completed, ntop will be installed under /usr/bin/

saihari:~ #which ntop

/usr/bin/ntop

When you run ntop (as a root user) for the first time, run ntop from a terminal window, this should initialize ntop and will let you set the password for the default ntop admin user (admin). Enter the password twice. By default the web interface is accessible from

http://localhost:3000

or

http://<ipaddress>:3000

Login with the user “admin” and password you just set.

Later on, you can start/stop/restart ntop as follows:

saihari:~ # rcntop start

Starting service ntop                 done

saihari:~ # rcntop stop

Stopping service ntop                 done

Quick Start with ntop

As soon as you logon to the web interface, everything becomes fairly straight forward as most if not all data shown in simple host/IP or protocol based tables and/or with nice grpahs, piecharts or graphs generated using the RRD Tools.

For instance,

If you would want to generate nice RRD Tools based graphs then it is important that RRD Tool (should be installed by default in openSUSE) and its RRD Tool devel packages, else ntop will report the following error at startup and disable the RRD Plugin which means no RRD based graphs.

**ERROR** RRD: Disabled – unable to create base directory (err 13, /usr/local/var/ntop/rrd)

To install RRD Tool and its devel package quickly from a terminal window,

saihari:~ # yast2 -i rrdtool rrdtool-devel

RRD Tool generated Graphs

The plugin architecture makes it easy to allow enhanced features like

netFlow/sFlow support where ntop can be configured to be a flow probe or a collector

Last time packet seen for hosts

ICMP traffic data

Plugin Architecture

Simply, click on the plugin (Yes/No) link to toggle between enable & disable from the Plugins menu.

You can also dump traffic data from ntop web interface

Dump Traffic Data

ntop has always been and will be so for long as a must have opensource tool for any network or system admin in any sized network or even on your home network. Click here to visit the project homepage.
