Windows EventLog parsing questions

no one with Windows EventLog parsing experience?

Hi, I am interested in answers also

[user54119]

Victor, maybe you could help

Hi!

I won't be able to help you much. #1, #2, and #4 need changes in agent (#4 also in server). #1 is implemented in 1.2.14 (event source, id, and severity passed as three additional parameters for event generated). #2 should be relatively easy to implement, I'll add this as feature request for 1.2.15. For #4 we plan to introduce new policy type to distribute parser configurations across nodes in a same way as you can distribute configuration files, but I cannot promise exact release when it will be implemented.

Best regards,
Victor

Hi Victor

Thanks for your information and your work. I agree with all points.

thanks
Dani

is #2 already implemented? My newest test says NO. (I didn't saw the feature request in the bug tracker)

any plans for #4? To deliver the parser files by agent policy is in my opinion the most elegant way.

[victor]

Yes, seems that it was forgotten. I've created issue in bug tracker (https://www.radensolutions.com/chiliproject/issues/641). As for #4, it will be in 2.0 branch, probably close to year end.

Best regards,
Victor

thanks for the update, ok for me.

Hi,

#2 is implemented in 1.2.17. This is turned off by default to maintain compatibility with previous versions. Setting parameter ProcessOfflineEvents in LogWatch section to yes or true will enable this feature. When on, agent will save timestamp of last processed event and on start will process all events since last processed.

Best regards,
Victor

Hi Victor

I come back to #2 and #4:

#2: I tested again with V2.0.-M3 but it is not working for me. Can you please check again?

#4: For which version is this planned?

Thanks, Dani

Hi,

can you please show me your agent config and content of registry entries under HKEY_USERS\.DEFAULT\Software\NetXMS\LogParserLibrary (assuming you run agent under Local System account - otherwise check same registry path under appropriate user)?

Best regards,
Victor

agent config (put together from server agent configuration and agent policy):

MasterServers = netxms.domain.com
ListenPort = 4700
RequireAuthentication = yes
RequireEncryption = yes
EnabledCiphers = 1
SharedSecret = longkey
EnableWatchdog = yes
LogFile = {syslog}
LogFile = ${ProgramFiles}\NetXMS\nxagentd.log
DebugLevel = 0
ConfigIncludeDir = ${ProgramFiles}\NetXMS\etc\nxagentd.conf.d
FileStore = ${ProgramFiles}\NetXMS\var
SubAgent = ecs.nsm
SubAgent = portcheck.nsm
SubAgent = ping.nsm
SubAgent = winperf.nsm
SubAgent = wmi.nsm
SubAgent = logwatch.nsm
SubAgent = filemgr.nsm

[filemgr]
RootFolder = ${SystemDrive}\

[logwatch]
ProcessOfflineEvents = yes
Parser = ${ProgramFiles}\NetXMS\var\eventlog-system-parser.xml
Parser = ${ProgramFiles}\NetXMS\var\eventlog-application-parser.xml

Registry Key HKEY_USERS\.DEFAULT\Software\NetXMS\LogParserLibrary:

LogWatch.Application REG_DWORD 0x552b7a44
LogWatch.System REG_DWORD 0x552b7a78

Have you found anything in my config and the registry?

Hi Victor.
Have you found anything in my config and the registry?

Hi,

it looks perfectly fine. I re-run tests on my system, and agent picks up everything as expected. Let's try to upgrade this system to 2.0-M4 (just to make sure I'm checking latest codebase) , and if it will not help I'll create special build with additional debug.

Best regards,
Victor

[user54119]

Ok, I will try V2.0-M4 first. When will it be available?

[victor]

It's just made available for download.

Best regards,
Victor

[user54119]

I have updated to V2.0-M4, but I see the same issue as before.

I tested like this:

parser xml:

<parser name="SystemLog">
  <file>*System</file>
  <rules>
    <rule>
      <match>(.*)</match>
      <level>1</level>
      <event params="1">100845</event>
    </rule>
  </rules>
</parser>

I turned off hardly a Win7-x64 virtual machine and started again. But I don't get an event '100845' in NetXMS for the windows error 6008 (last shutdown was unexpected) in the system eventlog.

Other windows events while the node is normal working are parsed ok and generate NetXMS events.

[victor]

Can you please set debug level to at least 2, reset system again, and check agent's log for message like

LogWatch: reading old events between ... and ...

and possibly also like this:

LogWatch: EvtQuery failed (...)

and post those lines and timestamp of "unexpected shutdown" event.

Best regards,
Victor

[user54119]

Hi Victor

Here the agent log with debuglevel=2. There was no "LogWatch: EvtQuery failed (...)".
There were these events for example before the NetXMS agent started:
Event-ID 41, Source=Kernel-Power, severity=critical, 04.05.2015 18:19:34
Event-ID 6008, Source=EventLog, severity=error, 04.05.2015 18:19:36

thanks
Dani
