Bandwidth graph Stopped Updating

Post by Box293 »

From this screenshot the Bandwidth graph has stopped updating:
Selection_101.png
If I tail /usr/local/nagiosna/var/backend.log and stop and start the source I see this:

Code: Select all

Error running initialization.
But it starts OK. I know traffic is being received (watching a tcpdump) and there are the correct firewall rules in place.

RRD file has not been updated for a while:

Code: Select all

ls -al /usr/local/nagiosna/var/pfSense/
total 1264
drwxrwsr-x+ 3 nna nnacmd    4096 Jul  3 06:45 .

Re: Bandwidth graph Stopped Updating

I did some more troubleshooting on this.

First:

Code: Select all

service nagiosna restart
NagiosNA backend stopped.
Traceback (most recent call last):
  File "/usr/local/nagiosna/bin/initialize_source.py", line 16, in <module>
    import rrdtool
ImportError: librrd.so.4: cannot open shared object file: No such file or directory
NagiosNA backend started...
Then:

Code: Select all

rrdtool
RRDtool 1.4.8  Copyright 1997-2013 by Tobias Oetiker <tobi@oetiker.ch>
               Compiled Oct 24 2014 09:26:45

Usage: rrdtool [options] command command_options
Valid commands: create, update, updatev, graph, graphv,  dump, restore,
		last, lastupdate, first, info, fetch, tune,
		resize, xport, flushcached

RRDtool is distributed under the Terms of the GNU General

For more information read the RRD manpages

So I looked at the Network Analyzer fullinstall script and it has an rrdtool section:

Code: Select all

rrdtool() {
	tar xf rrdtool-1.4.9.tar.gz
	(
		cd rrdtool-1.4.9
		./configure --prefix=/usr/local --disable-perl
		make
		make install
	)
	rm rrdtool-1.4.9 -rf
}
Clearly I'm not up to date.
I checked the upgrade script and there is no reference to installing / updating rrdtool.

So after updating rrdtool:

Code: Select all

rrdtool
RRDtool 1.4.9  Copyright 1997-2013 by Tobias Oetiker <tobi@oetiker.ch>
               Compiled Nov 11 2015 11:13:45

Same problem:

Code: Select all

service nagiosna restart
NagiosNA backend stopped.
Traceback (most recent call last):
  File "/usr/local/nagiosna/bin/initialize_source.py", line 16, in <module>
    import rrdtool
ImportError: librrd.so.4: cannot open shared object file: No such file or directory
NagiosNA backend started...
Does the file exist?

Code: Select all

find / -name librrd.so.4
/usr/local/lib/librrd.so.4
/tmp/nagiosna/rrdtool-1.4.9/src/.libs/librrd.so.4

ls -la /usr/local/lib/librrd.so.4
lrwxrwxrwx 1 root root 15 Nov 11 11:13 /usr/local/lib/librrd.so.4 -> librrd.so.4.2.2
Then I tried:

Code: Select all

yum install python-rrdtool

But I didn't proceed as it looked like it was going to downgrade rrdtool.

Not sure what to do now.

Re: Bandwidth graph Stopped Updating

Post by Box293 »

OK so with the help of @jdalrymple I was able to fix the problem.

Basically I needed to delete (I moved to be safe) the old python components, re-compile rrdtools and it was OK.

Code: Select all

mkdir /usr/local/lib64/python2.6/site-packages_backup
mv /usr/local/lib64/python2.6/site-packages/*rrd* /usr/local/lib64/python2.6/site-packages_backup
mv /usr/lib/python2.6/site-packages/rrdtool-0.1.1-py2.6-linux-x86_64.egg /usr/lib/python2.6/site-packages/rrdtool-0.1.1-py2.6-linux-x86_64.egg_backup
cd /tmp
wget https://assets.nagios.com/downloads/nagios-network-analyzer/2/nagiosna-2r1.0.tar.gz
tar xzf nagiosna-2r1.0.tar.gz
cd /tmp/nagiosna/
tar xf rrdtool-1.4.9.tar.gz
cd rrdtool-1.4.9
./configure --prefix=/usr/local --disable-perl --enable-python
make
make install
service nagiosna restart
Then after about 15 minutes the graphs started to appear. You can watch the RRD file to make sure it's being updated, it's in your source directory:

Code: Select all

watch 'ls -al /usr/local/nagiosna/var/pfSense/'
