It is powerful and very useful in a distributed environment, but the high-level search language abstractions can mask a number of mistakes that essentially force a reduce operation early in the pipeline, which removes Splunk's ability to parallelise its operations, whether in a distributed environment or on a single instance.Ī simple rule of thumb is that any operation which (in a naive implementation) would need to see every 'event' to do its work will not be parallelised. Much of Splunk's search functionality is powered a MapReduce implementation. If you are having trouble getting Splunk to utilise your hardware, consider the following factors: It is easy to see what Splunk is doing if you monitor these:Ī sign that you have a bottleneck caused by Splunk's implementation details - rather than your own hardware - is a pattern where you mostly see a single core at 100% with little-to-no disk usage, with sporadic spikes of activity by splunkd on an extra core as it hits the disk for more events. There are certain powerful operations with a single-threaded implementation that spend most of their time occupying a single core while barely hitting the disk. The conventional wisdom in the Splunk community is that Splunk's performance is heavily IO-bound, but this may be an assumption based on traditional use cases for Splunk. If using the AUR package, you can run both by starting the systemd splunk service.Īlternatively run with the Splunk binary:

Splunk has two main components: the splunkd daemon and the splunkweb service, a cherrypy web application. It has a reasonably robust CLI interface, and all the configuration is stored in. Splunk's installation directory is commonly referred to as $SPLUNKHOME.

There is also a splunkforwarder AUR package which will install the Splunk Universal Forwarder. There is now a splunk AUR package to install which will create the splunk user and group, install Splunk, and install a systemd unit file.

This article will focus on lesser known features or failures of Splunk, and how to run it healthily in Arch Linux. Much of it is in Unix-like man pages, particularly for the search and configuration reference files. Splunk's online documentation is open to the public and reasonably comprehensive. Raw data is parsed by sets of regular expressions (many of them built-in) to extract fields these fields then allow a query language that has fairly unique semantics but will be recognisable to user familiar with SQL or other structured data querying languages. Splunk provides a fairly high-level search interface to data.

The free license allows up to 500 MB of data per day, but it is missing a few features such as access control, alerts / monitoring and PDF generation Splunk is licensed based on MB of data indexed per day. Splunk is a horizontal technology used for application management, security and compliance, as well as business and web analytics. Splunk aims to make machine data accessible across an organization and identifies data patterns, provides metrics, diagnoses problems and provides intelligence for business operation. Splunk captures, indexes and correlates real-time data in a searchable repository from which it can generate graphs, reports, alerts, dashboards and visualizations.
