Installing Smokeping on CentOS 5.5

August 6, 2010 59 Comments

In this CentOS 5.5 tutorial we will be installing Smokeping and SmokeTrace on a CentOS 5.5 i386 server. The assumption is that you have a basic to medium understanding of Apache but if you follow this tutorial you should be able to complete the task successfully.

A bit on the software that we’ll be using:

Smokeping
SmokePing keeps track of your network latency:

* Best of breed latency visualisation.
* Interactive graph explorer.
* Wide range of latency measurment plugins.
* Master/Slave System for distributed measurement.
* Highly configurable alerting system.
* Live Latency Charts with the most ‘interesting’ graphs.
* Free and OpenSource Software written in Perl written by Tobi Oetiker, the creator of MRTG and RRDtool

http://oss.oetiker.ch/smokeping/

Preliminary Note:
I am using a CentOS 5.5 i386 base installation in this tutorial.

* www.how2centos.com (IP 10.0.0.100): CentOS 5.5 i386 base installation

Lets begin by installing the framework required by Smokeping.

Lets create a service startup script for Smokeping


# vi /etc/init.d/smokeping

# vi /etc/init.d/smokeping

#!/bin/bash
#
# chkconfig: 2345 80 05
# Description: Smokeping init.d script

# Get function from functions library

# Start the service Smokeping
start() {
        echo -n "Starting Smokeping: "
        /opt/smokeping/bin/smokeping >/dev/null 2>&1
        ### Create the lock file ###
        touch /var/lock/subsys/smokeping
        success $"Smokeping startup"
        echo

        kill -9 `ps ax | grep "/opt/smokeping/bin/smokeping" | grep -v grep | awk '{ print $1 }'` >/dev/null 2>&1 && killall speedy_backend
        ### Now, delete the lock file ###
        rm -f /var/lock/subsys/smokeping

Now browse to your new installed Smokeping and Smoketrace installation

Loved this Howto but when I get to the very end and browse to my website it just lists the smokeping.cgi file like a text file
Anonymous

The only suggestion I can make is to double check you Apache config and make sure the following has been done:

vi /etc/httpd/conf/httpd.conf

change > #AddHandler cgi-script.cgi
to > AddHandler cgi-script.cgi

Under

change > Options Indexes FollowSymLinks
to > Options Indexes FollowSymLinks ExecCGI
http://pulse.yahoo.com/_P7BSE7GUPH2HBT72WEGWOLRWEQ Nnyan

Thanks for the reply! I found I made a copy-paste error and got that fixed. I did not have a /smokeping/var directory (just created one) and finally I got this error:

ERROR: /opt/smokeping/etc/config, line 111: File ‘/opt/smokeping/etc/smokeping_secrets.dist’ is world-readable or writable, refusing it

so I just chmod’d that file and it’s up and running! this is awesome! Any chance of getting this into a script?

Sorry, what you are looking for isn’t here.

There are quiet a few things that could have gone wrong.

Please check the following:

1) Is Apache running?
2) What errors do you get in the Apache error logs?
3) Check to see you’re using your FQDN and not How2CentOS?
Akuler85

hi.. i dont know how to check, i’m still new for this linux command and open source software, please guide me. Thanks

If you’re still new to Linux then this is probably one of the most difficult installations you can do.

Short of allowing us access to your server I am afraid assisting you could be a lengthy process.

If you do require help then we can assist for a small donation. Please use the contact us page should you want our help.

Excellent guide !!!
Houckham

I now have a very odd problem. My first two targets are working great (and still working) I have added another three targets since and they are not populating any data. There graphs are present but no lines.
Anonymous

Very strange behavior. Are you able to ping them from the command prompt? Maybe a firewall.
Houckham

Yes, very strange! …A couple of reboots os the server later and all is good again, the new graphs are populated with data. :-S

I performed another test by adding one more target and same happened again.

What actions should be taken after adding targets? I am not sure if maybe a particular service needs to be restarted?
Houckham

OK. I restarted Smokeping service and httpd service and nothing changed. Still no data in the graphs after 3 hours.

I then rebooted the server, and it started working. Therefore there must be a service which needs to be restarted I guess – do you know which one?

Yo mate , have a question . Do you have any guide/addendum running this with seLinux enabled ? Your guide works perfectly with seLinux off , but my installs just wont have any of it when it’s switched on . Always really wanted to learn selinux properly , but i just find it hopelesly overcomplicated any time i try and use it.
NoYourName

great how to. I used this as an outline on a 64bit install of CentOS with the newest version of Smokeping. I don’t know if this is true with the version you used in the how to, but the path at the top of tr.cgi had to be changed to match smokeping.cgi. Thanks for the great writeup.
Nirav

i follow the docs, and when i try to open http://hostname.my.com/smokeping/tr.html page opens and when i pass host address i don’t see anything on screen… i even don’t see any log under /var no data under /data

Am i missing anything here?

– I’ve added 2 more hosts, i’ve restart smokeping…and they don’t load the RRD
– Traceroute isn’t working at all

I’ve tried what i could, but i can’t make it working. Can please someone help me with this issue? If possible, mail me at kdr (a) kdr (.) ms

Have you guys tried starting it with it’s binary file ?

# /opt/smokeping/bin/smokeping
Gilbert

try changing line 39 of the init script to

status /var/lock/subsys/smokeping
blahblahblah789

Yeah run the /opt/smokeping/bin/smokeping by hand.. When I did that I learned that I needed to install the RRDs.pm module. I did a yum install perl-rrdtools

I then reran smokeping and it worked for me so far.

Hello I found a fix – I added the extra detail to kill the speedy_backend in my service management script: /etc/init.d/smokeping

~~snip~~

# Stop the service Smokepingstop() { echo -n “Stopping Smokeping: ” kill -9 ps ax | grep "/opt/smokeping/bin/smokeping" | grep -v grep | awk '{ print $1 }' >/dev/null 2>&1 && killall speedy_backend ### Now, delete the lock file ### rm -f /var/lock/subsys/smokeping success $”Smokeping shutdown” echo}
~~end snip~~

good fix !

Thanks for the update! I have added your suggestion to the tutorial!
Herrmc

I used cut and paste from the tutorial and had the same problem as several post here (where: service smokeping status) showed “Smokeping is stopped”.
I edited the line to add the path as above… but failed to notice that in the tutorial text that the “S” in “Smokeping” is capitalized…. changed it to lower case and all is well with the service smokeping status
Herrmc

I have completed the install per the tutorial, and gone over it a few times… worked out some kinks from typos and missed lines.

Now I am getting this error on the webpage when I click the “Targets” link on the main page. I will keep looking for my typo or missed step, but was hoping someone could help on this one.

Installing perl-CGI solved the problem, but it showed another one:

I’m having the same problem on CentOS 6 64 bit – installed perl-CGI and now having problems with RRDs.pm.

Installed PackagesName : perl-rrdtoolArch : x86_64Version : 1.4.4Release : 1.el5.rf

# locate RRDs.pm
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/RRDs.pm

Tried changing the “use lib” line in bin/smokeping that points to …/RRDs/ to point to this folder or the RRDs.pm itself, without luck.

Any ideas?

@159ec39bc2b9bd92e357a6e5ae4e66cd:disqus , that was my first issue. If you see no change after you perform “chmod 700 /opt/smokeping/bin/smokeping” ensure SELinux is in permissive mode:
setenforce 0

Then, if you perform:

service smokeping restart
service smokeping status

Hopefully it’ll return “running.” If it is indeed the same issue as mine, it’ll return “smokeping dead but subsys locked” :-/

As this article is over a year and a half old I will have to go through an installation to familiarize myself again.

Expect an update this coming weekend.

Hello,
I have problem, I have CentOS 6.2 smokeping is running as service, but apache view cgi script as plain text. I checked httpd.conf and my option is corectly.

AddHandler cgi-script .cgi – is OK

pls Help me

Its seems there are a few people with this issue after following this guide:

when running /opt/smokeping/bin/smokeping it gives the following error:

Can’t locate RRDs.pm in @INC (@INC contains: /opt/smokeping/lib /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/RRDs /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5 /usr/share/perl5 .) at /opt/smokeping/lib/Smokeping.pm line 13.BEGIN failed–compilation aborted at /opt/smokeping/lib/Smokeping.pm line 13.Compilation failed in require at /opt/smokeping/bin/smokeping line 7.BEGIN failed–compilation aborted at /opt/smokeping/bin/smokeping line 7.

I too am getting the same message, however all packages are installed and up to date and the guide has been followed to the letter and re-checked several times. There doesn’t seem to be any answers and my linux isnt good enough to diagnose myself, I have tried for several hours.

If anyone can suggest anything I would be grateful
Chris

As per tutorials I have installed on Centos 5.5 no error found while installation. Smokeping service does not start. It shows OK but status it says stopped… If anyone help I would be greatful
Gwhite

Haven’t tested this theory yet, but it looks like that directory is the one used in CentOS 5. On the machine I’m currently attempting to configure I issued rpm -ql rrdtool-perl and part of the output was for /usr/lib64/perl5/auto/RRDs this is as close as I’ve gotten so far to something that looks right.

Any consultants that can help debug a SMOKEPING install?

We’re a Public Library and are trying to troubleshoot our 3 ISP Circuits that randomly drop off line. Of course the ISP says there is no problem. We’ve bumped the problem up to Corporate, but need real proof of the problem. We’re hoping that SMOKEPING will highlight the exact time and if it’s a complete drop or just a slowdown.

I’ve installed the app on VPS in the closest big city (Denver), and want to monitor the 3 circuits via monitoring the latency by pinging the three Firewall Interfaces just inside each of the cable modems.

It almost works. Both httpd and smokeping are running, and system monitoring is showing consistent traffic in and out, so it appears to be working. But there is no graphs, just a few text headings that seem to mimic the examples on the smokeping site.

If interested, please email your rates and availability (and a ballpark price to get a working SMOKEPING install).

Thanks (email me at vonskippy AT gmail DOT com).

Just discovered that myself and came here to check it was documented. Glad to see it’s been found already!

You don’t need to have the full path – just changing the capital “S” to lower case works.
