DMC setup prerequisites
This topic is a step in the process of setting up the Distributed Management Console (DMC) for either a Splunk Enterprise deployment or a single Splunk Enterprise instance. See About the Distributed Management Console in this manual.
By now you have decided which instance should host the DMC in your deployment. Before proceeding to Set cluster labels (for a deployment) or Configure DMC in standalone mode (for a single Splunk Enterprise instance), make sure you meet these prerequisites:
- Have a functional Splunk Enterprise deployment. See Scale your deployment with Splunk Enterprise components in the Distributed Deployment Manual.
- Make sure that your deployment is healthy, that is, that all peers are up.
- Make sure that each instance in the deployment (each search head, license master, and so on) has a unique server.conf
serverNamevalue and inputs.conf
- Platform instrumentation must be enabled for every Splunk Enterprise instance (except forwarders) that you intend to monitor. Every instance must meet the platform instrumentation system requirements:
- Each node must be running Splunk Enterprise 6.1 or higher.
- Platform instrumentation is supported for Windows, Linux, and Solaris.
- Forward internal logs (both
$SPLUNK_HOME/var/log/introspection) to indexers from all other instance types. See Best practice: Forward search head data in the Distributed Search Manual. Without this step, many dashboards will lack data. These other instance types include:
- Search heads.
- License masters.
- Cluster masters.
- Deployment servers.

Dashboard version dependencies
The dashboards in the Distributed Management Console rely on data collected from Splunk Enterprise internal log files and endpoints. Much of the data comes from platform instrumentation, which was introduced in Splunk Enterprise version 6.1. In addition, platform instrumentation has been enhanced in subsequent releases, for example by adding logging about iostats in Splunk Enterprise 6.4.0. The following table summarizes which quantities were introduced in which version.
The instances that you monitor in the console must meet these version requirements, or the related dashboard panels will appear blank.
|All dashboards||Most panels||Splunk Enterprise 6.1|
|KV store dashboards||All panels||Splunk Enterprise 6.2.0 (which introduced the feature)|
|Search head clustering dashboards||All panels||Splunk Enterprise 6.2.0|
|Distributed search dashboards||Panels about bundle replication||Splunk Enterprise 6.3.0|
|HTTP Event Collector dashboards||All panels||Splunk Enterprise 6.3.0 (which introduced the feature)|
|Scheduler dashboards||Most panels||Splunk Enterprise 6.3.0|
|Resource usage: Machine, Resource usage: Deployment||I/O panels||Splunk Enterprise 6.4.0|
To continue setting up your DMC in a distributed deployment, see Set cluster labels.
To continue setting up your DMC on a single instance, skip to Configure DMC in standalone mode.
