I have managed to put the text into the graphs ( watermark) by adding the
option directly into the respective php file ( e.g. check_snmp_int.php).
All the php files seem to have already an $opt[1] line which overrides the
general options.
I am still stucked with the PDF background file however.
Thanks once again!
----------------------------------------------------------------------------
I can't say I've ever tried that. I would think you need to append to
rather than replace the graph options though, so wouldn't it be ..
$conf['graph_opt'] .= " --watermark 'Test'"
(note the ".=" rather than just "=" and the space added before --watermark
)
I don't have my Nagios system to hand at the moment so can't take a
look myself. Remind me on Monday if you're still stuck and I'll have
a play with that myself.
Another option is to create some graphs outside of PNP altogether (but
using the .rrd databases created by PNP). See:
http://oss.oetiker.ch/rrdtool/doc/rrdcgi.en.html
Again, I can dig out some examples for you if you remind me during the
week (or do a search - I'm sure we've covered this topic before either
here or on the PNP email list some time in the last few months).

Hello again,
Can you please give some guidelines how to customize the PNP4Nagios
background page? I have tried using the $conf['graph_opt'] = "--watermark
'Test'" option, but it does not take it. Also modifications done on the
background.pdf file are not updated. Already restarted apache and nagios
services. In general I would like to add some logos and/or text.
Thank you!

Well done.
Yes, you can create a custom template.
Take a look under /usr/local/pnp4nagios/share/templates.dist and find
the file named check_snmp_int.php . Copy it to the directory
/usr/local/pnp4nagios/share/templates and then edit it to get the
wider line.
For example the line which reads:
$def[1] .= "LINE1:var1#003300:\"in \" " ;
Change it to read:
$def[1] .= "LINE3:var1#003300:\"in \" " ;
You will find documentation on how the LINE instruction works at:
http://oss.oetiker.ch/rrdtool/doc/rrdgraph_graph.en.html
and some general help on PNP templates at:

After adding the -r option it works like a charm!
Now in pnp4nagios I can see both values on the same graph: bytes in and
bytes out. I see them as two thin lines. Any way to make the lines thicker
and change their colour?

Was a typo error of the community string, after putting "public" instead
of "Public" everything looks cool.
Still 1 question:
If I try to query interface GigabitEthernet0/2 I get the response:
GigabitEthernet0/21:DOWN, GigabitEthernet0/23:DOWN, GigabitEthernet0/24:UP
No usable data on file (40 rows) , GigabitEthernet0/2:UP No usable data on
file (1 rows) , GigabitEthernet0/22:DOWN, GigabitEthernet0/20:UP No usable
data on file (1 rows) : 3 int NOK : CRITICAL
So ti seems that it takes all interfaces starting with "0/2" string. Any
way to limit this? Do I have to enter any escape character?
Thank you!

Ok,
Here is what I got so far:
1. If I run the command: ./check_snmp_int.pl -H 192.168.2.1 -C public -2
-n GigabitEthernet0/24 -fY -kqB -g -w 600000,600000,100,100,100000,10 -c
800000,800000,200,200,200000,20 -d 5 , I get the following output:
GigabitEthernet0/24:UP (16.9Kbps/26.2Kbps/0.0/0.0/0.0/0.0):1 UP: OK |
'GigabitEthernet0/24_in_bps'=16899;600000000;800000000;0;1000000000
'GigabitEthernet0/24_out_bps'=26237;600000000;800000000;0;1000000000
Before getting a correct output I run the command several times. The
initial output is GigabitEthernet0/24:UP No usable data on file (102 rows)
:(1 UP): UNKNOWN
2. Defined the following command in nagios:
define command{
command_name check_snmp_int
command_line $USER1$/check_snmp_int.pl -H $HOSTADDRESS$ -C
$USER5$ -2 -n $ARG1$ -fY -kqB -g -w $ARG2$ -c $ARG3$ -d $ARG4$
}
Where
And the corresponding service check:
define service{
use generic-service,pnpgraphed-service ;
Inherit values from a template
host_name test_sw
service_description Port 24 Bandwidth Usage
check_command
check_snmp_int!"GigabitEthernet0/24"!600000,600000,100,100,100000,10!800000,800000,200,200,200000,20!10
normal_check_interval 2 ; Check the service every
2 units under normal conditions
retry_check_interval 1 ; Re-check the service
every 1 unit until its final/hard state is determined
}
In nagios service status I get now: ERROR: Description table : No response
from remote host "192.168.2.1".
In resources I have defined $USER5$=Public
Ideas, please?
Thank you!

I have tried the SNMP plugin a few minutes ago and here is what I get when
running it from the command line:
./check_snmp_int.pl -H 192.168.2.1 -C public -n GigabitEthernet0/24 -k -w
200,400 -c 0,600
GigabitEthernet0/24:UP No usable data on file (1 rows) :(1 UP): UNKNOWN
The interface name I took it from listing all available interfaces on the
switch.
Any ideas, please?
Thanks!

Hello,
I am using Nagios to monitor the bandwidth usage of a couple of
switches/routers via the check_local_mrtgtraf command. The graphs I handle
via pnp4nagios. The problem I encounter is the following: if the monitored
bandwidth is at one point expressed in KB/s and then I bring a lot of
traffic through the router the, unit is changed into MB/s. The graphed
values seem not to take into consideration the change of the measurement
unit meaning that the 50KB/s seems to be at the same height as the 50MB/s
value in the graph.
Can anyone please help?
Thank you!
