Study Notes
Multisite Indexer Clusters
- Each site operates with its own set of peer nodes, sharing the same search heads.
- Site-specific replication and search factor rules apply to each site.
- Cluster administrator is responsible for defining "sites."
- True statements regarding multisite indexer clusters include ABD and therefore E (all of the above).
Master Node Functions
- The master node controls index replication and manages configurations within the index cluster.
- Peer nodes index data from inputs/forwarders and replicate data per master node instructions.
- Other capabilities include coordinating peer node activities and guiding search heads to data locations.
Cluster Reliability
- The cluster continues functioning even when the master node is offline.
- In multisite mode, a minimum of two peer nodes is required per site.
- Best practices dictate having at least RF+1 nodes in single-site mode.
Replication and Search Factors
- Replication Factor (RF): Indicates the total number of raw data copies maintained.
- Search Factor (SF): Specifies how many data copies can be searched and impacts recovery capabilities.
SmartStore and Buckets
- Remote storage for hot and warm buckets does not function using the cache manager.
- The indexer cluster can recover warm bucket data even if failed nodes meet or exceed the RF.
Search Head Clustering
- All search heads must have identical hardware specifications.
- Users can execute searches and visualize dashboards uniformly across different search heads.
- Search head clustering requires at least three search heads and a deployer server.
- Sizing guidelines for the deployer server emphasize adequate CPU and network resources for configuration management.
Data Integration and Movement
- Types of integration include various apps from Splunkbase, HDFS, re-forwarding data, and alert actions.
- Data can be sent to other systems via TCP and scheduled searches; raw text and syslog data are also transmitable through TCP.
Software Development Kits (SDKs)
- SDKs facilitate simplified code development in languages like Python, C#, JavaScript, and Java.
Additional Notes
- Summary indexes must be forwarded to the indexer tier in search head clustering.
- Correctly understanding the roles of master nodes, peer nodes, and the factors affecting replication and search is crucial for efficient Splunk administration.
