![]() The Universal Forwarder is a lightweight version of Splunk, with limited features. A Splunk Enterprise instance can be configured as a Heavy Forwarder. Splunk provides two different packages/binaries, the full version of Splunk (Splunk Enterprise) and the Universal Forwarder. The common question which keeps rattling in the mind of many Splunkers, when to use Universal Forwarder or the Heavy Forwarder. | rest splunk_server_group=dmc_group_cluster_master splunk_server_group="dmc_indexerclustergroup_xxxxxxxxxxxxxxxxxxxxxxxxxx" /services/cluster/master/indexes | fields title, is_searchable, replicated_copies_tracker*, searchable_copies_tracker*, num_buckets, index_size | rename replicated_copies_tracker.*.* as rp**, searchable_copies_tracker.*.* as sb** | eval replicated_data_copies = "" | foreach rp*actual_copies_per_slot | makemv replicated_data_copies | eval searchable_data_copies = "" | foreach sb*actual_copies_per_slot | makemv searchable_data_copies | eval is_searchable = if((is_searchable = 1) or (is_searchable = "1"), "Yes", "No") | eval index_size = round(index_size / 1024 / 1024 / 1024, 2).Whether to use Universal Forwarder or the Heavy Forwarder? As Splunk admins, we need to keep an eye on the underlying physical disk storage utilization and this search identifies the consumed physical storage for each index: Over time the size of the raw data size in each Splunk index bucket, especially cold buckets, will grow and consume disk storage. | inputlookup dmc_forwarder_assets | makemv delim=" " avg_tcp_kbps_sparkline | eval sum_kb = if (status = "missing", "N/A", sum_kb) | eval avg_tcp_kbps_sparkline = if (status = "missing", "N/A", avg_tcp_kbps_sparkline) | eval avg_tcp_kbps = if (status = "missing", "N/A", avg_tcp_kbps) | eval avg_tcp_eps = if (status = "missing", "N/A", avg_tcp_eps) | eval forwarder_type = case(forwarder_type = "full", "Heavy Forwarder", forwarder_type = "uf", "Universal Forwarder", forwarder_type = "lwf", "Light Forwarder", 1=1, forwarder_type) | eval last_connected = strftime(last_connected, "%m/%d/%Y %H:%M:%S %z") | search NOT status=missing Universal forwarders can fall off the radar for a number of reasons (didn’t restart upon machine startup, machine was decommissioned, etc.) and this search can help identify those that haven’t phoned home for a predefined timeframe: This blog is about what I found to be the most handy features of the console and what I frequently leverage from the tool. ![]() But this blog is not about how to configure the monitoring console whether in a multi-instance or single-instance deployment because there's a ton of info on that on Splunk docs. The dashboards behind the console rely on data collected from the different Splunk Enterprise deployments' internal logs located in both $SPLUNK_HOME/var/log/splunk/ as well as $SPLUNK_HOME/var/log/introspection/. The gist behind the monitoring console is its myriad of dashboards that provides a birds-eye-view health check of a multi-instance Splunk deployment. Since Splunk enterprise released 6.5.x "The Distributed Management Console" app was renamed to "The Monitoring Console" the app name change was not just a rename as the tool got bundled with a number of enhancements.
