HPOVFilter=filter
Specifies the events the adapter receives from OpenView NNM 6. This
value is ignored with OpenView NNM 5. The adapter can accept up to
4096 bytes for this parameter; you must enter the value in one continuous
line of input with no intervening line returns. Do not enclose the value in
quotation marks; if you enclose the value in quotation marks and turn on
adapter tracing, the trace file displays the following error:
Stream filtering set to: "{CORR{default}} .*"
Enter in TECAD_OVsInit...
Unable to initialize SNMP session system error: Invalid event \
filter (Filter parameter (""{CORR{default}}.*"") event \
specification must be "" or start with a ’.’)
Unable to initialize SNMP session system error: Bad file number
Enter in TECAD_OVsInitComplete...
can not initialize specific driver
The adapter also fails to initialize, and ovspmd sends the following
message:
# ovstart tecad_hpov
object manager name: tecad_hpov
state: FAILED
PID: 12901
last message: Unable to initialize SNMP session
system \
error: Bad file number
exit status: -
Turn on adapter tracing when you change the value for HPOVFilter to
make sure that the value was entered correctly or to see the errors
generated by it.
See the manual page for OVsnmpEventOpen for details on HPOVFilter
and the filter parameter.
WellBehavedDaemon
Specifies whether the adapter runs as an OpenView well-behaved daemon.
This value should always be TRUE.
Class Definition Statement File
The CDS file defines how events are constructed from the information that is sent
by OpenView. It is described in detail in “Class Definition Statement File” on
page 18 and in Appendix C, “Class Definition Statement File Reference” on page
155.
Errors in the .cds file definitions cause the adapter to not start successfully, which
often causes the adapter to exit with an exit (1). Therefore, change one definition
at a time and restart the adapter after each change to ensure that the new
definition works. If you make many changes before restarting the adapter, it is
more difficult to troubleshoot any problems; turning on adapter tracing helps you
locate the errors.
OpenView Event Example
The class definition in the following example is taken from the .cds file:
CLASS_OV_IF_FAULT
SELECT
1:ATTR(=,ENTERPRISE),VALUE(PREFIX, \
"1.3.6.1.4.1.11.2.17.1");
2:$SPECIFIC=40000000;
3:ATTR(=, "openViewSourceName");
