Hello Everyone,

I needed help setting warning and critical thresholds for Interface Errors and Interface Status moniotors

./check_nwc_health -t 20 --mode interface-errors --hostname xxx.xx.xx.xx --community blah --regexp --name '1.(1|2)|external' --selectedperfdata ''
OK - interface 1.1 errors in:0.00/s out:0.00/s , interface 1.2 errors in:0.00/s out:0.00/s , interface /Common/external errors in:0.00/s out:0.00/s | '1.1_errors_in'=0;1;10;; '1.1_errors_out'=0;1;10;; '1.2_errors_in'=0;1;10;; '1.2_errors_out'=0;1;10;; '/Common/external_errors_in'=0;1;10;; '/Common/external_errors_out'=0;1;10;;

./check_nwc_health -t 20 --mode interface-usage --hostname xxx.xx.xx.xx --community blah --regexp --name '1.(1|2)|external' --selectedperfdata 'traffic'
OK - interface 1.1 usage is in:0.00% (0.00Bits/s) out:0.00% (0.00Bits/s) (down), interface 1.2 usage is in:0.00% (22149.33Bits/s) out:0.00% (20203.56Bits/s), interface /Common/external usage is in:0.00% (33533.33Bits/s) out:0.00% (34769.78Bits/s) | '1.1_traffic_in'=0;;;0;0 '1.1_traffic_out'=0;;;0;0 '1.2_traffic_in'=22149.33;;;0;0 '1.2_traffic_out'=20203.56;;;0;0 '/Common/external_traffic_in'=33533.33;;;0;0 '/Common/external_traffic_out'=34769.78;;;0;0

This is for GTM. What should be the threshold values be set to? Based on the module, if you don't specify the warning or critical threshold it just reports ok

For the errors, looking at the performance data string I can see it will warning at 1 and critical at 10.

The interface usage does not appear to have any warning or critical. Really it comes down to what is applicable to your environment. What is specific about these interfaces that you want to warn? Is it connected to a fixed size pipe and you want to know when you are reaching it's capacity?

Needed help in some regex implementation in nagios config file

I have this explicitly working:

./check_nwc_health -t 60 --mode interface-status --hostname xx.xxx.xx.xx --community ******** --regexp --name 'Vlan3|GigabitEthernet1/0/(?!1|4|1[7-9]|2[0-1]|27|29|3[0-9]|4[0-4]|5[1-2])|Port-Channel(?!1|2|1[0-3]|48)|Tel' --selectedperfdata ''

defineservice{
use network-services
host_name CS301
service_description Interface Status
check_command check_nwc_health_regex!interface-status!******!\'Vlan3|GigabitEthernet1/0/(?!1|4|1[7-9]|2[0-1]|27|29|3[0-9]|4[0-4]|5[1-2])|Port-Channel(?!1|2|1[0-3]|48)|Tel\'!\'\'!60
notifications_enabled 0
}

This is returning me error, I am assuming because of the slashes, ? and !

I have simpler regex expression withing nagios config that works


defineservice{
use network-services
host_name GTM301
service_description Interface Status
check_command check_nwc_health_regex!interface-status!********!\'1.(1|2)|external\'!\'\'!60
notifications_enabled 0
}

Thanks in advance

It seems that the issue is the !

I need to be able to escape it properly, so it won't look at it as Nagios argument separator

You could put it as a user defined variable in resoruces.cfg and is referenced as $USERxx$
Or perhaps as a custom service object and reference it that way, like _INTERFACE and it is referenced as $_SERVICEINTERFACE$

Does that make sense?

\! did the trick

Are we all set to close this up then?

For the interface usage for example I am getting something like this

How can I explain this, even if we do the math it's more throughput through a 100MB pipe, this stuff is in Gbytes/S

Are you using the latest version of check_nwc_health?

https://labs.consol.de/nagios/check_nwc ... index.html

I did notice this bug fix:

2014-08-28 3.0.3.8
bugfix in interface-usage/ifspeed (Thanks Matthias Gallinger)

I have 3.5 which is after ifspeed fix. I am just using ifspeed flag to set the maxrange along with the units to MBi and calcualations are matching up with the my cacti graphs. Thanks for the pointer
