Antwort: RE: MRTG graphs problem - measurement units not taken into consideration

[Radu.Popa at technomatic.de]

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!
