Hello, Willard
Could you share your whole log4j config file?
I'm asking because the default one will have the following configuration:
<logger name="org.apache.cloudstack.alerts" additivity="false">
<level value="WARN"/>
<appender-ref ref="SYSLOG"/>
<appender-ref ref="CONSOLE"/>
<appender-ref ref="FILE"/>
<appender-ref ref="SNMP"/>
<appender-ref ref="ALERTSYSLOG"/>
</logger>
This is the only "logger" configuration that is using the SNMP appender
by default. And the package that it is using
(`org.apache.cloudstack.alerts`) does not exist. Therefore, it will
never log anything in the SNMP appender.
After looking at the code, I think that the packages that are meant to
be appended with the SNMP appender are `com.cloud.alert` and
`com.cloud.usage`. The interface of these implementations is in
"org.apache.cloudstack.alert", but still, the configuration there would
be invalid anyways as "org.apache.cloudstack.alerts" (ending with an
"s") does not exist. The implementations of that interface are all in
`com.cloud.alert` and `com.cloud.usage`. Therefore, you could use those
packages instead. Here is an example of how to configure that:
<logger name="com.cloud.alert" additivity="false">
<level value="WARN"/>
<appender-ref ref="SNMP"/>
</logger>
<logger name="com.cloud.usage" additivity="false">
<level value="WARN"/>
<appender-ref ref="SNMP"/>
</logger>

I followed the cloudstack documentation here:
https://docs.cloudstack.apache.org/en/4.18.0.0/adminguide/management.html?highlight=snmp#configuring-snmp-and-syslog-managers
to get SNMP traps working, however, no traps are being sent. I don't see
any related errors logged. I see no instances of failed library loads, but
I do not see. Do I need to manually install the libsnmp4j library myself?
I know it's reading the log4j config as I get this notification in the
management server log:
2023-08-07 18:20:42,842 INFO [c.c.u.LogUtils] (main:null) (logid:) log4j
configuration found at /etc/cloudstack/management/log4j-cloud.xml
Here is the log4j config for the SNMP appender (note that I have configured
syslog as well, and that is working).
<appender name="SNMP"
class="org.apache.cloudstack.alert.snmp.SnmpTrapAppender">
<param name="Threshold" value="WARN"/>
<param name="SnmpManagerIpAddresses" value="<redacted>"/>
<param name="SnmpManagerPorts" value="162"/>
<param name="SnmpManagerCommunities" value="public"/>
<layout
class="org.apache.cloudstack.alert.snmp.SnmpEnhancedPatternLayout">
<param name="PairDelimiter" value="//"/>
<param name="KeyValueDelimiter" value="::"/>
</layout>
</appender>
Any insight will be greatly appreciated.
Regards,
Willard
