![]() When not filtering I got the following errors WARNING Due to a limitation in the Windows EventLog subsystem, a query cannot contain more than 256 sources. I chose to use the Select option because there is a limit on the number of logs that NXLog can import. This is because when the service starts if the log doesn’t exist it doesn’t skip it, rather aborts. For each individual role (DC, ICA etc) I will have to add the specific event log in to the select statement. I’ve found the above seems to work on all the Windows machines. ![]() Changes I’ve made are adding the GELF extension, Adding the Input, Output and Route sections. When if file_exists('%LOGFILE%') file_cycle('%LOGFILE%', 8) # Rotate our log file every week on Sunday at midnight # Check the size of our log file hourly, rotate if larger than 5MB I have settled on the following for the nf file: define ROOT C:\Program Files (x86)\nxlogĪutodetectCharsets iso8859-2, utf-8, utf-16, utf-32 I installed it on the Windows 10 machine I have so that I could work out the configuration file settings. To do this, I used the NXLog Community edition which is free to download and use. Next task was to get events going in to Graylog. At the moment, I set it as a global input and followed the default settings. Within the main web interface the first thing I had to do was add an input. I manually created the DNS hostname in the AD DNS zone as well. This was done using the Netplan YAML file which was a new experience. First thing to do was log in to the console and set up the IP address. With the appliance deployed, I was able to note the username and passwords that are applicable to the appliance. I had to deploy the OVA file direct to the ESXi host rather than through vCenter as there is an error that appears when going through vCenter. It just makes life easier if everything is just ready to go. Where possible I wanted to use prebuilt appliances. It’s available as an OVA deployment which suits my ESXi environment nicely. Greylog keeps coming up as recommended on Reddit so I thought I would take a look. As a result, I wanted to look at another way to collect and aggregate log files etc. In a business environment it’s well worth doing and taking the cost. But, in a home lab environment where I have all the compute and storage on site, I just can’t justify the costs of sending to LA. I’ve blogged about OMS and using it previously. I am a huge fan of Log Analytics (formerly Operations Management Suite).
