Recommend a Windows server log analyser

Hi Experts

Can you recommend a good (free) basic Windows Event log analyser
I am looking for something simple, to perform on demand analysis
I have a server which generated 25K event in 4 days and I would like to analyse the logs (possibly offline as the server itself is getting old and slow)

Any suggestion ?

Is it always the same Event ID?
bbaoIT ConsultantCommented:
always first try something official from MS: Log Parser 2.2, a SQL-like query engine for collecting logs from varied sources.

Alexandre MichelManager; IT ConsultantAuthor Commented:

No, it is not always the same event, there are lots of different event IDs


Thanks for that. It looks promising. I will look into it.

Log Parser 2.2 seems to be a Command Line based tool. Is that correct? Any GUI that you know of?
bbaoIT ConsultantCommented:
you are correct.

yeah, its GUI version is also available now: Log Parser Studio


you may also try  Event Log Consolidator tool from SolarWinds - http://www.solarwinds.com/free-tools/event-log-consolidator

It is an efficient tool (GUI) to help you organize event logs in SMBs.

Damjan, thanks for the suggestion. I tried it ... but cannot get it to look at Windows "Application Event" logs. It seems to only look at the "File Replication Service" log for some reason...

Bing, the Log Parser studio looks great ... but ... I need to know SQL query to use it! Which I don't ... Luckily there are a number of samples I can use. This allowed me to create a first meaningful analysis

Are you familiar with SQL & Log Parser or should I ask a new question?

I would like to modify this query to only use the last nn entries or the entries since xx (date & time)

SELECT SourceName, 
    BIT_AND(EventID, 0x3fffffff) as EventID, 
    COUNT(*) As Entries
    GROUP BY SourceName, EventID, EventTypeName

Open in new window

TimeGenerated is a date & time field from the Event Log (in my case in the form of "d/mm/yyyy hh:mm:ss PM"). Not sure how to restrict the count to TimeGeneated > now()-24 hours or something like that

Also is there a way to restrict the report to only items whose Count is > 100 ?

just use WHERE clause. e.g. use WHERE TimeGenerated > '2016-08-08 00:00:00' to restrict events for today only.

> Also is there a way to restrict the report to only items whose Count is > 100 ?

use "SELECT TOP n" plus additional clauses as required to restrict the result to specific number or less. be aware that if used with GROUP BY on more than one field, it may cause additional fields not fully counted.

BTW, to get the benefits of Log Parser engine, you have to be familiar with SQL SELECT queries.
