How to Query for an event log details with a given event id?
c#, events
Solution
There are a few new twists if your going to query events from the new style Windows EventLogs.
- You will have to use the classes from the `System.Diagnostics.Eventing.Reader` namespace to read the new events.
- Your query will be in Xpath form, so that time value is tricky, see msdn for the `EventLogQuery` definition.
- Your program will run into access issues, be ready to impersonate a user that's included in the `EventReaders` AD group on the logging machine.
This sample shows some of the new access methods:
string eventID = "5312";
string LogSource = "Microsoft-Windows-GroupPolicy/Operational";
string sQuery = "*[System/EventID=" + eventID + "]";
var elQuery = new EventLogQuery(LogSource, PathType.LogName, sQuery);
using (var elReader = new System.Diagnostics.Eventing.Reader.EventLogReader(elQuery))
{
List<EventRecord> eventList = new List<EventRecord>();
EventRecord eventInstance = elReader.ReadEvent();
try
{
for (null != eventInstance; eventInstance = elReader.ReadEvent())
{
//Access event properties here:
//eventInstance.LogName;
//eventInstance.ProviderName;
eventList.Add(eventInstance);
}
}
finally
{
if (eventInstance != null)
eventInstance.Dispose();
}
}
Problem
- How to know whether a particular event (given event ID, time and node as inputs) is logged or not? [In this case, I know only one event will be logged] - If the event is logged, how do I get details like event description, Log-name etc.. for eg, I want to query for an event under the node Applications and Services Logs > Microsoft > Windows > groupPolicy > Operational, and event id is 5315 and time is current time.
