Eventlog monitoring based on description does'nt work

Post by appleseed »

Hello,

I'd like to collect any changes to group policies within our Windows Server 2003 Domain. Therefor I set up an eventlog test in hostmonitor:

Test by: RMA Agent

Log Source:
Computer: \\Server01 (Domain Controller)
Log: Security
Event source: Security

Alert Condition:
Computer: Any
Event Type: Any
Event Id: Any from the following: 566
Description: Any String from the list: "groupPolicyContainer" (as unique part of eventlog description which points to a policy change event)

Without the description everything works fine. But then a lot of events will be monitored which doesn't have to do with group policy changes

I've tried using asterisks or apostrophes - no success, any changes of GPO won't be written.

We use Host Monitor Enterprise 6.80 running on Windows 2000 Pro.

Thanks in advance

What message do you see in "Reply" field, when you try to perfom the test without description? Do you see correct event log message or something like "Message not found ..."?

Oh I see...

the phrase "grouPolicyContainer" won't be written in reply field. There are some bars instead:

Object Operation:||||Object Server:|DS||||Operation Type:|Object Access:|||||Object Type:|%{19195a5b-6da0-11d0-afd3...

Unfortunately there is nothing suitable in there wich refers to Group Policy exclusively

Hm. Bars mean CRLF characters, I suppose. What exact message do you see in "Event Viewer" applet for this particular Event Id?

The description for the eventlog entry looks like this:

Object Type: groupPolicyContainer
Object Name: CN={5EAA131E-C35F-40B7-912D-14BD2FA5583F},CN=Policies,CN=System,DC=test,DC=local

Well, I will try to explain what is wrong (I need to explain this to myself as well :wink: )
In fact event description contains message like
....
Properties:
Write Property
%{e48d0154-bcf8-11d1-8702-00c04fb96050}
%{f3a64788-5306-11d1-a9c5-0000f80367c1}
%{bf967a86-0de6-11d0-a285-00aa003049e2}
While Event Viewer replaces GUIDs with textual information like
...
Properties:
Write Property
Default property set
versionNumber
groupPolicyContainer
So, you may setup NT Event Lot test filter using GUID, then filter should work. In other word, use "%{bf967a86-0de6-11d0-a285-00aa003049e2}" instead of "groupPolicyContainer"
To be sure what exactly data is stored as event description, you may create HTML report with test results or simply widen Reply field (make the field wide enough for entire message).

Hi,

Is there a way to see event information in HM like event viewer does ?
Thus, with translated GUID's ?

Example: I'll monitor (via event 566) changes on specific groups.
Ok, I can use the GUID of that group to filter, but I will see in the event who made the changes etc ...

There is no such option yet. We plan to implement it, probably in version 8.xx
