check_graph_traffic adaptation for Cisco 4GB counter reset

[Menno Member Find all posts View Profile Close Menno]

Because cisco resets the in/out bytes counters after 4GB I got weird output from check_graph_traffic with my routers.
I made a quick and dirty change for this in check_graph_traffic at line 261 just before the '$in_traffic =' line:

# cisco resets the counters every 4GB ....
if ($in_bytes < $last_in_bytes) {$last_in_bytes -= 4294967296};
if ($out_bytes < $last_out_bytes) {$last_out_bytes -= 4294967296};

Probably there already is a plugin for this, but changing this plugin was faster than looking for another one.
It works fine here, maybe someone else can use this too..

Re: check_graph_traffic adaptation for Cisco 4GB counter res

Menno,

YOU ARE THE MAN!!!!!!!!!

Here you help me out again...

I have both Foundry and Cisco devices that behave in this manner. I will implement your additions to the check_graph_traffic.pl script and see if you fix me yet again!

Thanks!

counter reset error re-introduced in 1.3.3?

I installed version 1.3.3 lately and that contained a new check_graph_traffic.pl. I noticed the 4GB counter reset doesn't work anymore. I think this is because the check_graph_traffic.pl script now calculates in bits instead of in bytes, but didn't adapt the 4GBytes counter to bits.
So to correct this I made the following changes:

line 262
## Count must round at 4294967296 Bytes
line 268
$total = 4294967296 * 8 - $last_in_bits + $in_bits;
line 280
$total = 4294967296 * 8 - $last_out_bits + $out_bits;

Also in this version the perfparse traffic has been given a decimal comma instead of a dot and my perfparse database doesn't like that. For example when I now make a new service the decimal part is now part of the unit (for example plugin-output is 2700,1Bits/s, perfparse then shows 2700 as value and (,1Bits/s) as unit. So I commented those lines out:

line 363
# $in_perfparse_traffic_str =~ s/\./,/g;
line 364
# $out_perfparse_traffic_str =~ s/\./,/g;

Another small error is that the metric system is now used (1k = 1000 bits, was 1024 in older plugin) but at 2 places this is not adapted, lines 332 and 341 still divide by 1048576 instead of by 1000000.
