Known Issues

At the time of release, a number of known issues were reported that you should be aware of when running the probe.

Error messages from remote management commands on Solaris

When remotely managing the SNMP agent over the probe's HTTP/HTTPS interface on a Solaris system, the following messages appear in the error log:

Error: E-UNK-000-000: SNMP Message (priority=3): 
/netcool/omnibus/var/snmpv3/hosts/targethost.conf: Not owner
Error: E-UNK-000-000: SNMP Message (priority=3): 
/netcool/omnibus/var/snmpv3/hosts/targethost.local.conf: Not owner
Error: E-UNK-000-000: SNMP Message (priority=3): 
/netcool/omnibus/var/hosts/target.conf: Not owner
Error: E-UNK-000-000: SNMP Message (priority=3): 
/netcool/omnibus/var/hosts/targethost.local.conf: Not owner

In each case, targethost is replaced by the identity of the target for the command.

Despite these errors, the SNMP command is processed correctly. The messages result from a Solaris system call, because the files are not available. You can disregard these messages or choose to put the appropriate files in the named directories.

Unable to use nco_http on a Windows system

When using nco_http to send JSON data to the probe from a Windows systems, the value of the -data option is not processed correctly. Use either of the following workarounds:

Store the content of the -data option in the nco_http.props file to avoid entering it on the nco_http command line.
See Storing commands in nco_http.props properties file for information on using the nco_http.props file to hold data for the nco_http utility.
Use the nco_probeeventfactory utility instead of nco_http.
See Sending commands using nco_probeeventfactory for information on using the nco_probeeventfactory utility.

snmpget() function error messages from the Probe Rules Syntax Checker

The Probe Rules Syntax Checker can only access rules functions provided by the OMNIbus library.

The following functions are supported by the SNMP Probe but not by the OMNIbus library:

snmp_get()
snmpget_p()
snmpget_v2c()
snmpget_v2c_p()
snmpget_v3()
snmpget_v3_p()
snmpset()
snmpset_p()
snmpset_v2c()
snmpset_v2c_p()
snmpset_v3()
snmpset_v3_p()
drop_list_contains()
drop_list_remove()
drop_list_add()
read_trap_count()
read_drop_count()
get_queue_size()
print_engines()
get_engine_info()
update_engine()
set_engine_correction()

The Probe Rules Syntax Checker generates errors when checking the syntax of any rules files that contain any of these functions, or any other functions not in the OMNIbus library. You can disregard these messages.

Probe cannot run without `libncrypt`

On AIX® and Windows operating systems, running OMNIbus version 7.3.0, the probe requires the libncrypt library. Make sure that you have installed the correct OMNIbus fix pack as set out in the patch dependencies section of the description.txt file supplied with the download package.

IPv6 not supported on Microsoft Windows

When running on a Microsoft Windows system, the probe does not support using IPv6 to communicate with the SNMP target device. That is, do not use any of the following values for the Protocol property on Microsoft Windows:

UPDV6
TCPV6
ALLIPV6

Traps dropped due to malformed timestamps

The SNMP probe only processes traps that have a timestamp less than or equal to four bytes. The probe drops any trap that has a malformed timestamp (one that is greater than four bytes in size).
