Issue:
Discovery against F5 devices results in no Memory Component elements being created.
Environment:
All currently supported CA Performance Management releases
Cause:
MIB data on device is incorrect or incomplete.
Resolution:
The following shows the MIB OIDs the certifications in user rely upon for discovery, element creation and polling.

From:
DA_HOST:8581/typecatalog/certifications/snmp/F5BigIpMemory 
F5 BigIP Memory: <MIB>F5-BIGIP-SYSTEM-MIB</MIB> 
<Attribute name="sysStatMemoryTotal" type="Long"> 
<Source>1.3.6.1.4.1.3375.2.1.1.2.1.44.0</Source> 
<Attribute name="sysStatMemoryUsed" type="Long"> 
<Source>1.3.6.1.4.1.3375.2.1.1.2.1.45.0</Source> 
<Attribute name="sysDescr" type="OctetString">

<Attribute name="sysName" type="OctetString"> 
<Source>1.3.6.1.2.1.1.5.0</Source> 

From
DA_HOST:8581/typecatalog/certifications/snmp/F5BigIPMultiHostMemoryMib 
F5 BigIP Multi Host Memory: <MIB>F5-BIGIP-SYSTEM-MIB</MIB> 
<Attribute name="Index" type="ObjectID"> 
<Source>1.3.6.1.4.1.3375.2.1.7.4.2.1.3</Source> 
<Attribute name="sysMultiHostUsed" type="Double">

<Attribute name="sysMultiHostTotal" type="Double"> 
<Source>1.3.6.1.4.1.3375.2.1.7.4.2.1.2</Source> 

From:
DA_HOST:8581/typecatalog/certifications/snmp/F5BigIPGlobalHostMemMib 
F5 BigIP Global Host Memory: <MIB>F5-BIGIP-SYSTEM-MIB</MIB> 
Attribute name="Index" type="ObjectID"> 
<Source>1.3.6.1.4.1.3375.2.1.1.2.20.3</Source> 
<Attribute name="sysGlobalHostMemUsed" type="Long">

In this case after gathering a MIB dump for the device and browsing the data present from the F5-BIGIP-SYSTEM-MIB we found:

  • For the F5 BigIP Multi Host Memory and F5 BigIP Global Host Memory, there are no Index entries. We might see the MIB but wouldn't successfully discover or poll any elements due to no indecies present to use in element creation. No elements, no polled data.
  • For the standard F5 BigIP Memory VC neither of the propietary MIB OIDs in the F5-BIGIP-SYSTEM-MIB that we're seeking are found.
Engaged the device administration users or vendor for assistance with MIB data corrections to resolve this problem.
