[solved] rrdcached integration into PNP4Nagios doesn`t work

Hi,

I`m trying to integrate rrdcached support, as described here (http://docs.pnp4nagios.org/pnp-0.6/rrdcached) I added these 2 lines:
RRD_DAEMON_OPTS = unix:/var/run/rrdcached.sock
$conf['RRD_DAEMON_OPTS'] = 'unix:/var/run/rrdcached.sock';

into proper configs and I hoped it will start somehow working. But insted of it, I got red warning instead each graph. That warning is in attachment.

My config:
Debian Lenny @ HP DL 360G3 Proliant server (cca 3800 services [cca 1800 passive checks] and some 900 hosts )
Nagios 3.2.3, PNP4Nagios 0.6.7, rrdtool 1.3.1-4, Apache 2

I know there is "testing" note in config. My question is: Is this error caused because of testing state of rrdcached function in PNP or am I doing some mistake in integration with PNP?

Thank you for help.
Pep.

Your rrdtool version does not support rrdcached.

http://docs.pnp4nagios.org/pnp-0.6/rrdcached
You need svn version 1550 or higher.

Thank you for reply.

I installed rrdtool 1.4.4. Just in case I also recompiled PNP4nagios (ver. 0.6.7).

and in config file "process_perfdata.cfg" changed variable "RRDTOOL" to "RRDTOOL = /opt/rrdtool-1.4.4/bin/rrdtool"
in config file "config.php" I updated this line to new rrdtool path "$conf['rrdtool'] = "/opt/rrdtool-1.4.4/bin/rrdtool";"

And now error message tells me diffrenet think, which is attached. I also thought that as rrdcached is supposed to be a daemon I tried "ps xua | grep rrd
" and I got no output, so no rrd cached is runnig. Is this the problem?

Thank you.
Pep.

Thank you, it seems to work now. At least graphs are show now :)

My problem was here:
As I was reading the manual @ http://docs.pnp4nagios.org/pnp-0.6/rrdcached

I was skipping few first lines which optically looked to me as just some explaining of parameters of rrdcached. So I missed I have to manually run this command:
rrdcached -w 1800 -z 1800 -p /tmp/rrdcached.pid -j /tmp -s nagios -m 0660 -l unix:/tmp/rrdcached.sock

Thank you again for great graphs and quick help!
Pep.

I`m back again.

My graphs are shoving, but last data shown there are before I switched to rrdcached. I`ve triyed a gew suggestions, but with no success.

- when I run rrdcached like this: (I changed -w and -z for better debugging)
/opt/rrdtool-1.4.4/bin/rrdcached -w 60 -z 60 -p /tmp/rrdcached.pid -j /tmp -s nagios -m 0777 -l unix:/var/run/rrdcached.sock

I get this log in syslog:
Oct 26 16:00:18 Nagios-satelit-1 rrdcached[28503]: caught SIGTERM

Nagios process is running, checks are running.

RRD journals are created in /tmp (rrd.journal.1288101467.843651, ... and other 3 similar file names [owner root / group root]) But they dont grow, they have only 0 bytes.

Thank you.
Pep.

Hello,

any ideas? Where should I search for error messages which could aim me to right direction to solve that?

When I comment "$conf['RRD_DAEMON_OPTS'] = 'unix:/var/run/rrdcached.sock';" and "RRD_DAEMON_OPTS = unix:/var/run/rrdcached.sock" back to defaul state, graphs are generated again. But not witch rrdchached, I guess :(

now I run rrdcached under nagios user, but no diffrence except that I had to change "-j directory" because of the access rights:

ps -ef | grep rrdcached
nagios 29833 1 0 18:32 ? 00:00:00 /opt/rrdtool-1.4.4/bin/rrdcached -w 60 -z 60 -p /tmp/rrdcached.pid -j /tmp -s nagios -m 0777 -l unix:/tmp/rrdcached.sock

ls -la /tmp/rrdcached.sock
srwxrwxrwx 1 nagios nagios 0 27. říj 18.32 /tmp/rrdcached.sock

I also changed path /tmp/rrdcached.sock in variables "$conf['RRD_DAEMON_OPTS']" and "RRD_DAEMON_OPTS", of course.

Is that OK, that "rrd.journal..." files are only 0 bytes big? Should I search why they are not filled with data?

I still can see recently created graphs, but wihout data measure after switching to use "rrdcached.sock"

uff, Pep.

Justy to be sure, this is my rrdcached version:
/opt/rrdtool-1.4.4/bin/rrdcached -help
RRDCacheD 1.4.4
Copyright (C) 2008,2009 Florian octo Forster and Kevin Brintnall

(I Just downloaded the last version of RRDtool in its homepage, hoping that it will fit my needs. After all I don`t know how to get exactly SVN version 1550 or higher because on rrdtool homepage I haven`t found anything like SVN versions in download section)

In log level 2 I can see the message "...update ERROR unknown option..." now. It is the same error message, as I saw for the firts time instead the graph, but now it`s in log, as you can see in the attachment. So it looks like I still don`t have correct version of RRDtool :( Am I right?

The RRDs perl modules are not based on rrdtool 1.4.4
Did you build rrdtool with perl bindings?

Please check your rrdtool installation.

Before I tried to install rrdcached support in PNP4nagios I use rrdtool installed by Aptitude only. Than, after you told my to upgrade rrdtool, I downloaded it and I did this:

installed these packages: libcairo2-dev, libglib2.0-dev, ibsdl-pango-dev, libxml2-dev
and then:
./configure
make
make install

Nothing else.

My experiences are not such big to be able to answer you your question "Did you build rrdtool with perl bindings?", sorry

I attached the output of ./configure of rrdtool.

and thats the problem.

Please read the rrdtool install instructions.
./configure --help will give you also some informations how to build the perl bindings

Also the pnp4nagios ./configure summary will show you the detected rrdtool AND perl RRDs version.

The pnp4nagios configure scripts provide a --help option and some hints to point PNP to the correct perl RRDs Libs
