Re: Missing percentdiscards, percenterrors, discards, and errors graphs

Hi,

I added the missing counters to the mib2-X-interfaces-pkts group and start
graphing the counters again. I have newts storage because of that I don't
have lost any information except the last days after the upgrade to version
22.

   <group name="mib2-X-interfaces-pkts" ifType="all">
      <mibObj oid=".1.3.6.1.2.1.31.1.1.1.7" instance="ifIndex"
alias="ifHCInUcastPkts" type="Counter64"/>
      <mibObj oid=".1.3.6.1.2.1.31.1.1.1.8" instance="ifIndex"
alias="ifHCInMulticastPkts" type="Counter64"/>
      <mibObj oid=".1.3.6.1.2.1.31.1.1.1.9" instance="ifIndex"
alias="ifHCInBroadcastPkts" type="Counter64"/>
      <mibObj oid=".1.3.6.1.2.1.31.1.1.1.11" instance="ifIndex"
alias="ifHCOutUcastPkts" type="Counter64"/>
      <mibObj oid=".1.3.6.1.2.1.31.1.1.1.12" instance="ifIndex"
alias="ifHCOutMulticastPkt" type="Counter64"/>
      <mibObj oid=".1.3.6.1.2.1.31.1.1.1.13" instance="ifIndex"
alias="ifHCOutBroadcastPkt" type="Counter64"/>
      <mibObj oid=".1.3.6.1.2.1.2.2.1.13" instance="ifIndex"
alias="ifInDiscards" type="counter"/>
      <mibObj oid=".1.3.6.1.2.1.2.2.1.14" instance="ifIndex"
alias="ifInErrors" type="counter"/>
      <mibObj oid=".1.3.6.1.2.1.2.2.1.19" instance="ifIndex"
alias="ifOutDiscards" type="counter"/>
      <mibObj oid=".1.3.6.1.2.1.2.2.1.20" instance="ifIndex"
alias="ifOutErrors" type="counter"/>
   </group>

Also modified the mib2 thresholding-config to take account of the changes
and use the 64 bit counters:

      <expression description="Trigger an alert if incoming usage of any
interface reaches or goes above 80% of its maximum speed for three
consecutive measurement interv
als (only for interfaces that have a maximum speed value defined)"
type="high" ds-type="if" value="80.0" rearm="65.0" trigger="3"
ds-label="ifName" filterOperator="OR" ex
pression="ifHCInOctets * 8 / 1000000 / ifHighSpeed * 100">
         <resource-filter
field="ifHighSpeed">^[1-9]+[0-9]*$</resource-filter>
      </expression>
      <expression description="Trigger an alert if outgoing usage of an
interface reaches or goes above 80% of its maximum speed for three
consecutive measurement interva
ls (only for interfaces that have a maximum speed value defined)"
type="high" ds-type="if" value="80.0" rearm="65.0" trigger="3"
ds-label="ifName" filterOperator="OR" exp
ression="ifHCOutOctets * 8 / 1000000 / ifHighSpeed * 100">
         <resource-filter
field="ifHighSpeed">^[1-9]+[0-9]*$</resource-filter>
      </expression>

Best regards,

Jose
