perfdata output of check_snmp_int.pl not following specs about manubulon-snmp

[dnsmichi]

Can you send in a PR which fixes the issue please? :)

My perl knowledge is close to zero, but I think that https://github.com/dnsmichi/manubulon-snmp/blob/master/plugins/check_snmp_int.pl#L718 is the line to modify :/

[dnsmichi]

Hm, do you have some sample data then which I could use for further analysis? (plugin output and perfdata on the cli)

[pclerie]

This is the command line that produces the interface data being shown, as taken from /var/log/icinga2/debug.log:

'/usr/lib/nagios/plugins/check_snmp_int.pl' '-2' '-B' '-C' 'logisys-monitor' '-H' '172.28.5.3' '-M' '-Y' '-c' '0,600' '-d' '300' '-f' '-k' '-n' '\bpppoe0|\beth1|\btun0' '-t' '5' '-w' '300,400'

And if we enter that as is on the command line the output is:

eth1:UP  (0.0Mbps/0.0Mbps), tun0:UP  (0.0Mbps/0.0Mbps), pppoe0:UP  (0.0Mbps/0.0Mbps):(3 UP): UNKNOWN | 'eth1_in_bps'=1114;300000000;;0;100000000 'eth1_out_bps'=752;400000000;600000000;0;100000000  'tun0_in_bps'=5075;300000000;;0;0 'tun0_out_bps'=3401;400000000;600000000;0;0  'pppoe0_in_bps'=22887;300000000;;0;0 'pppoe0_out_bps'=12744;400000000;600000000;0;0

(The reason for the UNKOWN status is because I removed the parts of the output saying it could not write to the output file in /tmp.)

And the performance data from this output get written to the database as:

perfdata = E'eth1_in_bps=1761;300000000;;0;100000000 eth1_out_bps=969;400000000;600000000;0;100000000 '' ''pppoe0_in_bps''''=23036;300000000;;0;0 pppoe0_out_bps=12687;400000000;600000000;0;0 '' ''tun0_in_bps''''=4569;300000000;;0;0 tun0_out_bps=3055;400000000;600000000;0;0'

There are three things to note:

• The first is only apparent when looking at a full debug.log. The interfaces are not always returned in the same order. Each in/out pair is listed alternately in first position.

• In the command line output, the pairs are separated by two spaces, while the in|out counters are separated by a single space.

• Finally, here is how I unpack the database input line:

  • Each pair of counters is between single quotes. So the first pair is: 'eth1_in_bps=1761;300000000;;0;100000000 eth1_out_bps=969;400000000;600000000;0;100000000 '.
  • The second pair is: ' ''pppoe0_in_bps''''=23036;300000000;;0;0 pppoe0_out_bps=12687;400000000;600000000;0;0 '
  • And the last: ' ''tun0_in_bps''''=4569;300000000;;0;0 tun0_out_bps=3055;400000000;600000000;0;0'

---

The above is part of my internal bug report. The command line above will produce counters:

• eth1_in_bps
• _'pppoe0_in_bps'
• _'tun0_in_bps'

Hope that helps.

Hi,

i think, i have the same issue, i use the actually version from this page and use the following command

'/usr/lib64/nagios/plugins/check_snmp_int.pl' '-H' '172xx.xx.xx' '-L' 'sha,des' '-l' 'icinga2' '-X' 'XXX' '-x' 'XXX' '-Y' '-d' '60' '-e' '-f' '-kM' '-n' '48' '-w' '80,80' '-c' '90,90' '-B' '--64bits'

Perfdate Output looks very strange:

'D-Link Corporation DGS-1250-52XMP HW A1 firmware 2_01.006 Port 48_in_error'=0c

In this form i didn't get the grafana graph.

Hi,

The problem with the spaces in the interface name - not to mention the length. I don't have a D-Link here: Are ifName or ifAlias better? Have you already tried that?

Otherwise you could think about a PR which converts the names. Convert spaces to _ and shorten the name using a regexp filter. The firmware version actually has no place in a switch port name. I thik "Port_48_in_error" would be enough. It's strange what D-Link is doing here.
