How to Deal with Cluster Manager Failure in Splunk

There are 2 ways... (The below ways for Single Site Cluster only)

1) Replace the manager node on the indexer cluster
--> Install & Stop Splunk on Separate Server
--> Copy the backup of the old manager's configurations to the new manager
--> Start Splunk on new manager Server

2) Implement cluster manager redundancy
To achieve cluster manager high availability, you can deploy two or more cluster managers in an active/standby configuration. You can configure the managers to support either automatic or manual failover.

🛡 Wazuh Mastery Pack · 15 of 15 — Wazuh vs Other SIEMs

The honest take, after operating most of them in production:

✅ Where Wazuh wins:
• No license cap — ingest as much as you want
• Built-in EDR (FIM, SCA, Active Response, rootkit checks)
• Compliance mappings out of the box
• Lightweight agents, multi-OS, easy enrollment

⚠️ Where Wazuh struggles:
• No native UEBA / ML-driven anomaly detection
• OpenSearch-based, slower than Splunk's SPL
• Dashboards less polished than commercial tools
• Community-driven support (paid tier exists)

The decision tree I actually use:

🔹 Tight budget + need SIEM + EDR + compliance → Wazuh, every time
🔹 Big budget + need ML / UEBA / fast search → Splunk
🔹 Need flexibility above all, willing to DIY → ELK
🔹 Already have OSSEC → migrate to Wazuh today

Wazuh isn't the best at any single thing. It's the best free SIEM/XDR that ships with everything in one box. Pair it with good engineering, and you outperform stacks that cost 50× more.

That's a wrap on the 15-part series. Thanks for reading along — and to everyone who commented, shared, or DM'd me with feedback: it kept me writing.

The full PDF pack is pinned to my profile if you missed earlier sheets.
