![]() ![]() You’ll be asked for a local username and password, Keep note of it, as we’ll need it later. Start Splunk by accepting license sudo /opt/splunkforwarder/bin/splunk start -acept-license. Install the package using sudo dpkg -i b This typically install the splunkforwarder on /opt/splunkforwarder for Debian based ubuntu wget -O splunkforwarder-9.0. "" You could use following steps to configure the Splunk Universal Forwarder on a EC2 machine or any other VPS servers.ĭownload the splunkforwarder package for EC2 OS from Splunk Downloads web page e.g. Configuring Splunk Universal Forwarder on EC2 Unlike HTTP Event Collector, Universal Forwarder are lightweight agents which are installed as a package on the host machine which periodically monitors the log file in the background and pushes them to the Splunk Cloud. Since HTTP Event Collector relies on HTTP connections, it might impact the application performance. While Splunk provides something called HTTP Event Collector allowing us to push data from servers to Splunk cloud over HTTP/HTTPs, I opted to use the universal forwarder. Splunk provides different type of forwarders, universal forwarder, heavy forwarder and light forwarder. To push logs to Splunk cloud, we’d need to use one of Splunk forwarders. Splunk forwarders send data from data sources to Splunk cloud for indexing which makes it easier for searching, querying and building dashboards. Different Ways of Forwarding Logs To Splunk This article is simply a documentation of the steps I took to configure Splunk universal forwarder to forward application logs from a EC2 server and a dockerized app deployed on ECS Fargate. I wanted to try and understand what goes into configuring the Splunk universal forwarder. Using Splunk queries, we could query those log data to debug any production issues as well as to build different charts and dashboards for both engineering and business reporting.Įven though I was fairly comfortable with writing Splunk queries to build dashboards utilizing the log data, I’ve never actually configured servers to forward logs to Splunk. At my day job, we use it extensively to aggregate application logs hosted on different servers. Splunk is a platform for aggregating, indexing, searching & analyzing logs and other machine generated data. Long story short - unless you have a reason to prevent restarts on a UF, absolutely set "restartSplunkd" to true in the Splunk Cloud Universal Forwarder ![]() This would get quite tedious and requires either being on the system with the UF or having changed the UF's password to access it's rest API. The alternative here is to touch a reload rest endpoint on the UF every time you would like to reload the configuration. This means the only way to automatically reload the new inputs configuration on the UF is to trigger a restart. The problem is the Deployment Server does not do any reload of any sort. Technically the UF doesn't require a restart. If it fails, it will then restart.Īdd these to any serverclasses that you'd like to reload. # to the client, that client will try to reload that app. #* If true and issueReload is also true, then when an updated app is delpoyed #* This is only valid on forwarders that are newer than 6.4. #* If you don't want to immediately start using an app that is pushed to a client, you should set this to false. #* If true, triggers a reload of internal processors at the client when a member app or a directly configured app is updated #* Can be overridden at the serverClass level and the serverClass:app level. #* If true, restarts splunkd on the client when a member app or a directly configured app is updated. By adding the following settings to the serverclass, Splunk will opportunistically reload (and issue a restart if the objects are not reloadable). ![]() In Splunk 6.4 and greater, the Universal Forwarder is reloadable via the nf. ![]()
