Re: [Devmon] if_err stats

Can someone advise where I'm going wrong? Have I got a syntax errror
somewhere, or is the basic configuration wrong?
The thresholds file is set to alert yellow if more than 1 error occurs, and
red if more than 3 occur using DELTA on ifInEps.
The messages file displays green status, but I never get alerted if
interface errors occur.
thresholds
# Create thresholds for all the error rate counters
# oid name : color : limit : Error message
ifInEps : yellow : >=1 : {ifName}{ifAliasBox} - Input
error detected : ({ifInEps})
ifInEps : red : >=3 : {ifName}{ifAliasBox} - Input
error detected : ({ifInEps})
ifOutEps : yellow : >=1 : {ifName}{ifAliasBox} - Output
error detected : ({ifOutEps})
ifOutEps : red : >=3 : {ifName}{ifAliasBox} - Output
error detected : ({ifOutEps})
message
Input Error RED Status if: {ifInEps.thresh:red}
Output Error RED Status if: {ifOutEps.thresh:red}
Input Error YELLOW Status if: {ifInEps.thresh:yellow}
Output Error YELLOW Status if: {ifOutEps.thresh:yellow}
TABLE:rrd(DS:ds0:ifInEps:COUNTER; DS:ds1:ifOutEps:COUNTER)
Ifc name|Errors incoming|Errors outgoing
{ifName}{ifAliasBox}|{ifInEps.color}{ifInEps.errors}|{ifOutEps.color}{ifOutEps.errors}
