[Devmon] Alerting for FCS-err and RCV-err

[Mario V. <mar...@gm...>]

Hi,

I've noticed that the FCS-Err and RCV-Err in the CISCO "sh int counters
errors" command are not strictly available via snmp (I stand to be corrected
though).

The output of {ifInError} and {ifOutError} succesfully display the number of
errors on the ports since boot, but I'd like to be alerted when either
increases (even by 1) as I can then go and check the ports on the related
switch.


I've used the {ifInEps} and {ifoutEps} built-in transform which should
calculate if there is a difference between checks and alert me if a
difference exists.  At the moment, I am not receiving an alert when errors
increase the numbers and am not sure why.


Is there a better way to do this or can anyone see where I've gone wrong in
the settings below:


*transforms (built-in):*
# Do delta transform on all error counters
ifInEps         : DELTA         : {ifInErrors}
ifOutEps        : DELTA         : {ifOutErrors}

*thresholds:*
ifInEps         : yellow        : >=1   : {ifName}{ifAliasBox} - High input
error ({ifInEps})
ifInEps         : red           : >=10  : {ifName}{ifAliasBox} - Very high
input error ({ifInEps})
ifOutEps        : yellow        : >=1   : {ifName}{ifAliasBox} - High output
error ({ifOutEps})
ifOutEps        : red           : >=10   : {ifName}{ifAliasBox} - Very high
output error ({ifOutEps})

*message:*
Input error:  yellow={ifInEps.thresh:yellow}, red={ifInEps.thresh:red}
Output error: yellow={ifOutEps.thresh:yellow}, red={ifOutEps.thresh:red}

TABLE:
Ifc name|Errors in|Error rate in|Error load in|Errors out|Error rate
out|Error load out
{ifName}{ifAliasBox}|{ifInErrors}|{ifInEps.color}{ifInEps}|{ifInErrPct.color}{ifInErrPct}%{ifInErrPct.errors}|{ifOutErrors}|{ifOutEps.color}{ifOutEps}|{ifOutErrPct.color}{ifOutErrPct}%{ifOutErrPct.errors}



Thanks,
