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?

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!

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!

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!
