collector.properties
For Collector versions 19.182-25 and later the collector.properties file can be modified on existing Collectors allowing you to configure its internal processes for specific uses. This file is generated automatically when installing a Collector.
note
Starting with collector 19.170+, the installation directory is secured to users belonging to the sumologic_collector group. Modifying collector.properties may require sudo privileges. For more information, see Enhanced File System Security for Installed Collectors.
Configure collector.properties
Stop the Sumo Logic Collector service.
- On Windows:
net stop sumo-collector - On Linux:
sudo ./collector stop
- On Windows:
Navigate to the installation directory of an existing Installed Collector and open the
collector.propertiesfile in the config directory with a text editor. An example path is:/<sumo_home>/config/collector.propertiesAdd the parameters you need, see all of the available parameters in the collector.properties parameters table below.
infoKeep all of the existing parameters already in the file. If you remove any, the Collector will not be able to restore them and could result in collection issues.
Save the file in the same location. Maintain UTF-8 format.
Start the Sumo Logic Collector service.
- On Windows:
net start sumo-collector - On Linux:
sudo ./collector start
- On Windows:
Default Collector installation location
The default collector installation locations are:
Linux:
/opt/SumoCollector//usr/local/SumoCollector
Windows:
C:\Program Files (x86)\Sumo Logic CollectorC:\Program Files\Sumo Logic Collector
collector.properties example
The example below has parameters that were automatically added by the Collector based on the configuration of the user.properties file, such as cpuTarget. The collector.properties file is different, only modify parameters found in the parameters table below. If you see another parameter you want to adjust, check user.properties to see if it's an available configuration parameter.
The collector.properties parameter collector.localfile.inputType has been added and set to nonblocking to tell the Collector to use the Windows Rollable path for UNC file paths. That is the only collector.properties parameter in this example.
receiver.url = https://collectors.sumologic.com
windows.remote.jni = true
cpuTarget = -1
json.sync.mode = UI
logIngestStatus = Normal
collector.debug.forceRestart = -1
collector.localfile.inputType = nonblocking
collector.properties parameters
The table below has parameters that you can manage.
info
Do not modify any other parameters found in the collector.properties file, it could result in collection issues.
