Hi all! I wonder if in this mailing list is there anyone involved in the development of check_snmp_int.pl plugin or the newer version, check_snmp_netint.pl, or someone that using these plugins, have seen what I mention as an inconvenience that may have been solved by modifying the code.
A few days ago I decided to migrate my own servers to Debian GNU/Linux Jessie. Having migrated my firewall, I started getting an error in the Nagios Manubulon plugin check_snmp_int.pl since it does not find the interface eth1. # ./check_snmp_int.pl -H 10.1.0.10 -l Us3r -x passw0rd0 \ > -X passwOrd1 -L md5,des -w 1500,295 -c 2500,400 -k -B --label -n eth1 ERROR : Unknown interface eth1 This was running smoothly prior to migration, although it now seems to have changed the description of the interfaces: # ./check_snmp_int.pl -H 10.1.0.10 -l Us3r -x passw0rd0 \ > -X passwOrd1 -L md5,des -n -v Alarm at 10 + 5 SNMPv3 AuthPriv login : Us3r, md5, des Filter : OID : 1.3.6.1.2.1.2.2.1.2.2, Desc : Realtek Semiconductor Co., Ltd.

RTL-8100/8101L/8139 PCI Fast Ethernet Adapter:UP:(1 UP): OK | So I checked the equivalence between ifDescr and ifName: # snmpwalk -v 3 -u Us3r -l authPriv -a MD5 -A passw0rd0 -x DES \ > -X passwOrd1 10.1.0.10 ifDescr IF-MIB::ifDescr.1 = STRING: lo IF-MIB::ifDescr.2 = STRING: Realtek Semiconductor Co., Ltd.

RTL-8100/8101L/8139 PCI Fast Ethernet Adapter:UP (in=93.0Kbps/out=13.1Kbps):(1 UP): OK | It's a pity If it can not solve because quite a while I was using the check_snmp_int.pl plugin and was very happy with their results. But now in Debian Jessie I'm having this problem. It seems that something has changed in the SNMP service included in the new version of Debian since before (on Debian Wheezy) the description matched the ifName: # ./check_snmp_int.pl -H srv01.freesoftware -C public -w 1500,295 \ > -c 2500,400 -n -v Alarm at 10 + 5 SNMP v1 login Filter : OID : 1.3.6.1.2.1.2.2.1.2.2, Desc : eth0 OID : 1.3.6.1.2.1.2.2.1.2.1, Desc : lo Name : eth0, Index : 2 eth0:UP:(1 UP): OK | I think it is easier to identify interfaces such as eth0, eth1, etc, rather than by its manufacturer/model. Is it possible to change the behavior of the plugin so that "-n" allows to specify ifName instead of ifDescr and the plugin output is based on ifName because of this change in Debian? I was reading the script though I'm not sure what changes would be necessary to achieve this behavior. Thanks in advance.
