This app contains nine dashboards, made to compliment the Monitoring Console during maintenance activities involving data sources and the Forwarding tier for pre- and post-validations.
With the exception of the "Poll Instance" and "Data Source Monitoring" dashboards, all dashboards are portable, allowing their source XML to be copy-and-pasted into a new dashboard on another Splunk instance. (To make a dashboard portable, search and replace the dcm_internal_index macro with index=_internal, and replace the dcm_audit_index macro with index=_audit)
Shows high-level trends of indexing rates, deployment clients, Splunk Stream forwarders, distinct data source counts, and average data source throughput.
Click the Indexing Rate, Events Per Second, HTTP Event Collector Data Received, Forwarding Splunk Instances, Deployment Clients Phoning Home, Stream Forwarders Phoning Home, Instances Reporting Red/Yellow Data Forwarding Health, or SC4S Sources Forwarding Data values to expand the metric to the timechart below. The Events Per Second timechart contains distinct values over time for Indexes, Sourcetypes, Sources, and Hosts to identify changes to ongoing trends. The Deployment Clients and Stream Forwarders Phoning Home values are the distinct count for the given time span, with a minimum span to compensate for adjusted phone home intervals above default.
Click the Show Filters link on the top to expose the time picker, and to display indexers by instance for smaller deployments, or by site for larger deployments.
Reviews internal logs and metrics for troubleshooting common forwarder issues. Check this dashboard when performing maintenance activities on forwarders. Includes forwarder information, throughput metrics, stops and starts, index/sourcetype/source details, health status, resource usage, splunkd logs, deployment server messages, and indexer discovery messages.
Although this dashboard was made primarily for troubleshooting use cases around forwarding, it may also be used to investigate many issues involving both Splunk Enterprise and Universal Forwarder instances. This is as long as their internal logs are forwarding to your indexers, to allow this app to review for issues.
Filter by a single forwarder (Splunk instance) at a time, or a batch of forwarders during maintenance or triage.
Reviews internal logs and metrics for troubleshooting common data source issues. Check this dashboard when deploying configuration changes to data sources. Includes tstats data over time, as well as detected issues with permissions, enqueuing, timestamp parsing, line breaking, aggregation, future timestamps, and time disparity.
Overlays are added to Tstats Events panels to see distinct values over time for indexes, sourcetypes, sources, and hosts, to help identify changes in ongoing trends.
Tick the Sparklines checkbox in the Tstats Details panel to review individual index, sourcetype, source, and/or host trends beside the other split-by fields. Adding these sparklines may cause these dashboard searches to consume lots of memory -- make sure the Splunk Enterprise instance running this app has a healthy amount of memory available or memory tracker configured properly.
Reviews REST and tstats data for troubleshooting common data model issues, similar to the Data Source Troubleshooter but for identifying issues with a particular data model. Works best when installed on a search head which includes the underlying data models (i.e. Splunk_SA_CIM) and associated knowledge objects to identify constrained data (i.e. CIM-compliant tags). For example, on the search head hosting the Splunk Enterprise Security (ES) app.
Reviews events by sourcetype and host over time, optionally monitoring and alerting on anomalies such as missing data. Use this dashboard to review a particular data source for issues such as spikes in data ingestion or outages.
Optionally, visit the Data Source Monitor Configuration dashboard to input sourcetypes and hosts for active monitoring. This feature requires installation of the Machine Learning Toolkit (MLTK), alerting on anomalous values by using the DensityFunction algorithm. See the Configuration section for details.
Reviews a particular data source (either a sourcetype or a host) for anomalous values. This dashboard works alongside the Data Source Monitoring dashboard during troubleshooting.
Reviews Splunk Connect for Syslog (SC4S) indexed fields and metrics for investigating common syslog ingestion issues. Use this dashboard if you have SC4S configured in your deployment, and need to troubleshoot issues related to SC4S syslog collection.
To review data in the metrics panels, the SC4S environment variable "SC4S_DEST_SPLUNK_SC4S_METRICS_HEC" should be properly configured to forward metrics data. See the SC4S documentation for the Splunk data source.
Reviews REST API data from the Deployment Server(s), extending the information given by Forwarder Management. Includes a similar interface to Forwarder Management, but with the addition of monitoring multiple Deployment Servers, and many filters and extended information of both Deployment Clients and Servers.
This feature is for use wherever the Data Collection Monitor app is installed on-premise, such as on the Monitoring Console or Deployment Server, per Installation instructions. It will not work on the Splunk Cloud Search Head.
A bit unique relative to the other dashboards, the Poll Instance dashboard pulls information from a remote Splunk instance for diagnostic information, such as from an unpeered Splunk Enterprise instance or a Universal Forwarder. Use this dashboard to troubleshoot issues such as file inputs not ingesting or to validate current configuration settings.
This dashboard requires configuration before use. See the Installation section below regarding setup remote Splunk credentials.
This feature is for use wherever the Data Collection Monitor app is installed on-premise, such as on the Monitoring Console or Deployment Server, per Installation instructions. It will not work on the Splunk Cloud Search Head.
This generator command powers the Poll Instance dashboard, and may be used in your own SPL to query REST API endpoints of Splunk Enterprise and Universal Forwarder instances. This is most useful for instances which are not search peers of this instance, which is a requirement of the "| rest" command. To help with compatibility, "| pollinstance" also returns a table similar in formatting to "| rest".
Syntax:
| pollinstance splunk_host=<string> [splunk_port=<int>] account=<string> object=<string> [uri]
splunk_host - the host/IP of the target Splunk instance to poll information fromsplunk_port - the management port of the target Splunk instance (optional, default is 8089)account - the account name given to the username/password combination, as saved in this app's Configuration dashboardobject - determines what output to return from the instance; choose one of the following:rest - Perform a GET operation from the given REST API endpoint (requires uri to be specified)all - Returns information from all the objects listed belowinfo - System high-level infosettings - System high-level settingsmessages - System messagesconfs - Current configuration valuesinputstatus - Input status (tailing processor, exec processor, modular inputs, TCP/UDP)apps - Splunk Appsdata - Data inputs and outputs (TCP cooked/raw, UDP, forward servers)kvstore - KV Storecluster - Indexer Clustershcluster - Search Head Clusterdeployment - Deployment Clientslicenser - License Slavessearch - Distributed search peershealth - Splunkd Healthstatus - Introspection (CPU/memory/disk utilization, partitions, splunkd processes)Examples:
Poll data from remote Splunk instance "splunk.mycorp.com" REST endpoint "/services/server/status", using credentials from account "Main_IDXC":
| pollinstance splunk_host="splunk.mycorp.com" account="Main_IDXC" object="rest" /services/server/status
Poll all objects from remote Splunk instance "10.50.1.22" on non-standard port "8091", using credentials from account "Tampa_UFs":
